IEC 62474 Database Update with Exemption Lists – July 2019

The IEC 62474 (Material Declaration) Database was updated on July 21-22, 2019. This was a very extensive and complex update:

  • There were a significant number of additions and changes made to the IEC 62474 declarable substances list (DSL) and references substance list (RSL) during this update. The new DSL/RSL version is D18.00.
    • One of the four SVHCs added to the REACH Candidate List in July 2019 is a possible constituent of electrotechnical products and therefore included in the DSL;
    • Several other substance groups and substances were added due to emerging regulatory changes;
    • A major review of substance names and synonyms was performed. Changes reflecting this review were included in this update;
    • DSL and RSL entries that are new or changed have a last revised date of 2019-07-21;
    • Entries that were removed can be identified by comparing the new DSL and RSL with D17.01 (see archive section).
  • An update to the complementary list was also posted (CL18.00). This is a list of REACH Candidate List SVHCs that were screened out and not added to the EEE industry DSL.
  • The initial release of exemption lists for EU RoHS Annex III and China RoHS were published as of July 22, 2019. The EU RoHS Annex IV exemption is in final review and will be published soon.
  • There were no changes made to the Material Class List (MCL) — update coming soon
  • The data exchange format (DX) had a major revision (X8.00) based on the revised IEC 62474:2018 standard published last year.
    • The revised XML schema and developer’s table were posted on April 14, 2019.
    • The revision supports a new  Declaration for Compliance module that enables suppliers to provide a summary declaration against a DSL.  It is similar to the IPC-1752A Class C declaration.

Additional information on the Database update is provided below.  For technical support, consulting, or training on this database update or on the full set of new features and changes that were recently added to IEC 62474 or the revised IEC 62474-2018 data exchange format and XML schema, please contact ECD Compliance.

Declarable Substances List (D18.00)

The DSL is used globally by EEE manufacturers, suppliers, and IT solution providers as a common list of substances that should be declared throughout the supply chain, allowing downstream manufacturers to access product compliance to substance regulations around the world. The DSL includes declarable substances and substance groups together with reporting thresholds, reportable applications, and other information that is important for creating a material declaration.

Three new Declarable Substance Groups (DSG) were added to the DSL based on regulatory developments.  This includes TNPP, one of the four SVHC added to the REACH Candidate List on July 16, 2019.  TNPP was the only SVHC that the IEC 62474 Validation Team (VT62474) found may be a constituent of an EEE product above the reporting threshold.  The other three SVHCs were added to the Complementary List (CL18.00) of SVHCs that have been screened out by the team.  Anyone that is aware of new information that a screened out SVHC may exist in EEE above threshold, should contact the VT or ECD Compliance.

The new DSG entries added to the DSL are listed in the table title “New DSL entries”.

Several other updates to declarable substance entries were also made, mostly to adjust declarable substance and declarable substance group names to align with the names used in regulations. There was also an extensive update to the formatting of CAS numbers and Basis Descriptions (i.e. the regulations that are the basis for adding the substance to the DSL).  The use of a standardized format will make it easier for IT systems to automatically parse and extract the relevant information.

The recently added substance clarification data field in the DSL now includes the substance description specified in the REACH Candidate List.  This is a normative field in the DSL and needs to be used to determine whether or not a given substance or mixture falls under the DSL entry.  Substance clarification may also include other information and notes to assist users with the DSL entry. The substance clarifications were simplified in D18.00 compared to version D17.01 – this will make it easier to identify which DSL entries have a substance clarification.

Other changes to DSL entries in this update include:

  • DIBP was added to “Phthalates, Selected Group 1 (DEHP, DBP, BBP, DIBP)” (ID=00036)
  • Several substance and substance group names (including several PAH substances) were adjusted to match the current names in legislation

Most of the changes to existing RSL entries were due to adjustments in the names of Declarable Substance Groups. This included:

  • Azocolourants and Azodyes which form certain aromatic amines
  • Phthalates, Selected Group 1 (DEHP, DBP, BBP, DIBP)
  • Polybrominated biphenyls (PBB)
  • Polybrominated diphenyl ethers (PBDE)
  • Polychlorinated naphthalenes

Additional changes to the RSL:

  • The name of the reference substance “Mercuric chloride” (ID=R00174) was changed to “Mercury, chloro(cyclohexylmethyl)-“
  • The duplicate reference substance Lead phosphate (ID=R00157) was deleted – this substance is also listed as Lead (II) phosphate (ID=R00165) (same CAS number) . Lead phosphate was added as a synonym to entry R00165 for completeness.

Exemption Lists

The initial release of exemption lists for EU RoHS Annex III and China RoHS were posted. The EU RoHS Annex IV exemption list is in final review and will be published soon.

When creating a material declaration, the following identity information is applicable:

  • List Authority=”IEC62474″;
  • List Identity=”EU-RoHS-AnnexIII” or “China-RoHS”
  • List Version=”E1.0″.
  • The Entry IDs of individual exemptions are provided in column D of the list.

Based on user input, some of the IEC 62474 exemptions lists have exemptions that are split into sub-exemptions when there are multiple expiry dates or technical requirements that change over time. Each sub-exemption has a sub-exemption ID (referred to as sub-identity). This has the benefit of enabling suppliers who are creating material declarations for their products to more precisely identify the specifics of the exemption they are declaring, including the product categories for which the exemption is valid.  However, the sub-exemption concept has the disadvantage of making the exemption lists more complex, although suppliers do not need to use the sub-exemptions. If a supplier’s part or material is used in many different product categories, they can select the original exemption (sub-identity=’00’).

For additional information on sub-exemptions, see the IEC 62474 blog article on exemption lists.

Given that this is the first release of the IEC 62474 exemption lists, there may be some adjustments based on feedback. Please check the IEC 62474  database regularly for any updates.

Background

The IEC 62474 DSL is an internationally recognized and harmonized list of substances and substance groups that are regulated and may be constituents of electrical and electronic products and systems. Electrical and electronic manufacturers and suppliers use the DSL in their design and supply chain management operations to specify and control substances of concern. The list is updated as needed based on regulatory changes. For additional information about IEC 62474, see the article About IEC 62474. The IEC 62474 database is available online; the standard itself which specifies the material declaration requirements and rules may be purchased in the same manner as any other IEC standard — from the IEC webstore or a reseller.

 Additional Information

The updated DSL version is D18.00. The new and modified entries have a last revised date of 2019-07-21.

If anyone is aware of errors or omissions in the database (e.g. a regulated substance that is not included in the DSL but has potential EEE applications) or a regulatory reference that is out of date, please send an email to ECD Compliance and we will raise the issue with the  IEC 62474 validation team.

For further support on IEC 62474 or your substance management program, please contact ECD Compliance.

IEC 62474 Material Declaration Exchange Format Adding Declaration for Compliance

On April 14, 2019, the revised IEC 62474 data exchange (DX) format — including XML schema and the Developer’s Table (DT) – was published on the IEC 62474 database.  It introduces several new capabilities to the International Material Declaration Standard for the Electrotechnical industry.

The material declaration information will now be organized in “sectionals”, similar to the way that IPC-1752A uses sub-sectionals and classes.   Each sectional represents a different type of information that may be included in the IEC 62474 material declaration and is represented as an element under ‘Product’ in Figure 1 below. The sectionals include:

  • Declaration for Compliance (represented by the Compliance element in figure below);
  • Composition Declaration (represented by the Composition element);
  • Material Class Declaration (represented by MaterialClassDeclaration);
  • Query Statement Declarations (represented by QueryList)

Note: the three additional elements shown under product (ProductID, Attachment, and Exemptions) provide additional information, but are not considered to be sectionals.

A material declaration that conforms to IEC 62474:2018 needs to include at least a Declaration for Compliance or a Composition Declaration but it may also include both.

Figure 1: Graphical Representation of Product Complex Type (generated using Liquid Studio)

 

 

 

 

 

 

 

 

 

Declaration for Compliance

The Declaration for Compliance is a true/false declaration against each entry in a Declarable Substance List (DSL), indicating whether or not the declarable substance (DS) (or declarable substance group (DSG)) is present in the product. This is similar to a Class C declaration in IPC-1752A. The Declaration for Compliance does not include any information on product build hierarchy, but it includes sufficient information for the recipient of the material declaration to be able to assess compliance against the regulations covered by the DSL.

For a declaration for compliance, the supplier creating the declaration would select true for a given DS/DSG entry if:

  • The DS or DSG is a constituent of the product being declared;
  • The DS/DSG may be present above the reporting threshold level; and
  • the reportable application is applicable.

Composition Declaration

The Composition Declaration may be used by the supplier to provide information about product parts, materials and/or substances that make up the product.  IEC 62474 requires that at least declarable substances that are present in the product be reported, but the Composition Declaration may include other substances, up to and including a full material declaration (FMD).

The Composition Declaration also supports declaration and identification of articles (as per the EU REACH regulation) to help manufacturers meet EU REACH SVHC reporting requirements (see related post “Reporting REACH SVHCs using the is Article Flag in IEC 62474 Declarations”)

We will be adding additional information on the revised IEC 62474 material declaration exchange format once the new schema and Developer’s Table are published in the IEC 62474 database.

 

IEC 62474 –Exemption Lists to be Posted on IEC 62474 Database

The IEC 62474 ED2 (published November 2018) includes a provision to post and maintain substance exemption lists on the IEC 62474 database.   Three lists have been approved so far (see Table 5) and will be posted in March 2019 when the upgraded IEC 62474 database features come on line.

Table 5: Exemptions Lists Approved for Publication on IEC 62474 Database

Regulatory BasisList authorityList identityInitial List version
EU RoHS 2 Annex III

EU RoHS 2 Annex IV
(2011/65/EU)
IEC62474EU-RoHS-AnnexIVE1.0
China RoHS 2IEC62474China-RoHSE1.0

The initial release of the EU RoHS Annex III exemptions will include all of the exemption renewals that were published in 2018 and the additional ten Delegated Directives published in February 2019.

Identification of Exemption Lists

Each exemption list will be identified by the List authority = “IEC62474”, a list identity, and a list version.  The list identity will remain fixed for a given regulation and the list version will be revised every time that an edit is made to the list. The list version is in the format Emmm.n where ‘mmm’ represents the major revision number and ‘n’ represents a minor editorial update.

Identification of Exemption Entries

Each exemption entry will also have a unique ID consisting of three parts: a base ID, a version ID, and a sub-exemption identity (explained below).  This IEC-ID is intended to uniquely and permanently identify a specific exemption even when a regulation re-uses an exemption number after significantly modifying the technical aspects or scope of an exemption.

The IEC-ID for each entry is of the format “nnnnn-vv-ss”, where nnnnn = base ID number, vv = version (alphabetic), and ss = sub-exemption ID (sub-identity).

Sub-exemptions: Exemption Details that Vary over Time or by Product Category

A unique aspect of the IEC 62474 exemption lists is that exemptions with technical requirements that change over time or have different effective/expiry dates based on product category will be subdivided into sub-exemptions that each have a unique technical requirement, effective date and/or expiry date. Each sub-exemption will share the base ID and version ID of its parent exemption but will have a unique sub-exemption identity (referred to as the sub-identity).

For example, the revised exemption 6(a) that comes into effect on July 1, 2019 is excerpted in Table 6. The example lists three sub-exemptions with different expiry dates for most category 8/9 products, category 8 in vitro, and category 9 industrial.  The IEC-IDs for the three sub-exemptions are: 00033-B-01, 00033-B-02, 00033-B-03 – the last two digits indicate the sub-identity. The original exemption as specified in the regulation always has the sub-identity ‘00’.

Other Information Included in the Exemption List File

The IEC 62474 exemption lists also provide additional information about each exemption such as the regulatory basis for the exemption and the DSL entry that the exemption applies to. “First Added” and “Last Revised” dates are provided to record when a specific entry was added or changed in the exemption list.

Format of the Exemption Lists (xls vs XML)

The IEC 62474 exemption lists are initially provided only as spreadsheets in xls format but may be migrated to an XML format in the future.  The XML format will make it easier for IT systems to automatically import revisions to the exemption list.

IEC 62474 – Amendment 1 to Broaden Use Across Industries

IEC 62474 Ed 2 is undergoing a quick amendment to broaden its use across multiple industries by allowing alternate Declarable Substance Lists (DSL) to be used in creating a material declaration.

A few other clarifications are also being made. The voting period for the IEC 62474 AM1 Committee Draft for Vote (CDV) closes on April 19th. If all National Committees (NC) approve the document, the amendment can skip the final draft (FDIS) voting and go straight to publication.

There are no other technical changes in Am1 that impact the data exchange format or the information on the IEC 62474 database.

IEC 62474:2018 is available from the IEC webstore and standards resellers worldwide.  The revision has also been approved as a European Standard (EN 62474).

IEC 62474 – Ed.2 Data Exchange Format to be Released in March 2019

The IEC 62474 data exchange format, including XML schema and developer’s table (DT) are being updated based on the requirements specified in the updated ED2 standard. Several new features have also been requested, including:

  • Flag to indicate that the declaration is a full material declaration
  • Safe use information, identifying a safe use condition from a list or a separate statement
  • A tag to identify declarable substance groups associated with a substance in a composition declaration
  • Identification of standardized or industry specified query lists
  • Attachments at Material and Product Part levels

The revised format has been approved, including all of the proposed new features. A final review and adjustments are being made. The revised data exchange format will be published around mid-March.

IEC 62474 Declarable Substance List (DSL) – July 2018 Update

The IEC 62474 Declarable Substance List (DSL) was updated to Version D16.00 on July 8, 2018. The update includes relevant SVHCs from the recent update to the EU REACH Candidate List and a few other changes to declarable substance and reference substance entries as described below.

Declarable Substance List (DSL)
Eight of the ten SVHCs added to the REACH Candidate List on June 27th were included in the DSL based on their potential presence in EEE products. The substance review for possible EEE uses was conducted by the IEC 62474 Validation Team (VT62474) with experts from Asia, Americas, and Europe. Note: if anyone is aware of information that may be relevant to whether or not one of the substances may be present in EEE products, please forward the information to the VT (by sending an email to iec62474(at)rohs.ca).

One of the additions, the phthalate DCHP, had been proposed for the Candidate List in 2016, but the Member State Committee (MSC) representing the EU countries couldn’t agree as to whether or not it met the requirements for listing. The substance was referred to the European Commission who made the final decision and issued Commission Implementing Decision (EU) 2018/636 in April to add the substance.

The additions to the DSL are listed in Table below.

One entry was deleted from the DSL. The restriction of BNST (Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene) was repealed by Canada and the DSL entry (ID=00127) was accordingly deleted from the DSL.

Reference Substance List (RSL)
Nine reference substances were deleted from the Reference Substance List (RSL). The substances are SVHCs that are on the REACH Candidate List; however, they have been previously screened out because no applications were found whereby the substances would remain in EEE products at or above the reporting threshold level. To avoid confusion that can arise when a regulated substance is on the RSL but not on the DSL, the VT 62474 agreed to remove the substances from the RSL for consistency.

One other RSL entry was modified. The RSL entry R00147 (substance name “Hexabromocyclododecane (HBCDD)”) was modified to remove the CAS registry number “3194-55-6”. In January 2018, a new entry (R00492) was added to the RSL with the specific substance represented by this CAS number  (1,2,5,6,9,10-hexabromocyclodecane), so listing the CAS number against the generic substance entry was no longer needed. To avoid confusion from having the same CAS number listed in two different RSL entries for the same substance group, the CAS number was removed from the generic entry.

Material Class List (MCL)
No changes were made to the MCL during this update to the IEC 62474 database. However, a major revision to the Material Class List is currently underway — the changes will better support Life Cycle Assessment (LCA) of EEE products.

Upcoming Major Changes to the IEC 62474 Standard and Database
The IEC 62474 standard was due for its periodic review and revision a couple years ago (like any other IEC standard) and the IEC/TC111 Maintenance Team has been working hard to improve the standard based on feedback we’ve received from many users and other stakeholders.

The FDIS version (Final Draft International Standard) of the revised standard was completed in March and is currently in translation; it should be available for voting at the end of July (voting is by country). In the interim, the VT62474 is busy drafting the changes to the XML schema to meet the new requirements and compiling other information that will be added to the database such as new data fields for the DSL and exemption lists. We will be posting additional information on this site over the next few months.

For immediate guidance, ECD Compliance supports manufacturers, solution providers, and suppliers on the implementation of IEC 62474. We can work with you on the transition to the new requirements and provide implementation guidance. For additional information, contact ECD Compliance.

The IEC 62474 Database
The IEC 62474 DSL is available on the IEC 62474 database at: http://std.iec.ch/iec62474. The new and modified entries have a last revised date of 2018-07-08.

IEC 62474 Declarable Substance List – Sept 2017 Update

The IEC 62474 Declarable Substance List (DSL) was updated on September 3, 2017. The updated version (D14.00) includes the additional SVHC added to the REACH Candidate List in July (Perfluorohexane-1-sulphonic acid and its salts) and changes to two existing DSL entries and some maintenance to reference substance list entries, including:

  • The nickel substance entry (nickel metal) is replaced by a nickel/nickel compounds declarable substance group with tenreference substances;
  • The numerical part of the reporting threshold of Hexabromocyclododecane (HBCDD) was reduced to 0.01 mass% of article to align with the EU POPs regulation; and
  • The reference substance name “Lead hydrocarbonate” was replaced by “Trilead bis(carbonate) dihydroxide” and the duplicate reference substance “Lead (II) carbonate basic” (same CAS, different name) was delected.

The DSL is used globally by EEE manufacturers, suppliers, and IT solution providers as a common list of substances that should be declared throughout the supply chain, allowing downstream manufacturers to access product compliance to substance regulations around the world. The DSL includes declarable substances and substance groups together with reporting thresholds and reportable applications.

IEC 62474 Declarable Substance List – Jan 2017 Update

The IEC 62474 Declarable Substance List (DSL) was updated on January 12, 2017 following the European Chemical Agency (ECHA) addition of substances to the EU REACH Candidate List on the same day. The update includes those of newly added REACH SVHCs that may be constituents of EEE products. A few additional maintenance updates were also made.

The DSL is used globally by EEE manufacturers, suppliers, and IT solution providers as a common list of substances that should be declared throughout the supply chain, allowing downstream manufacturers to access product compliance to substance regulations around the world. The DSL includes declarable substances and substance groups together with reporting thresholds and reportable applications.

The update includes:

  • two of the four SVHCs added to the EU REACH Candidate List on January 12, 2017
  • reference substances for one of the SVHCs that is a group of substances
  • an update to the reportable application field of one of the Lead/Lead compound substance groups
  • deletion of two reference substances

The IEC 62474 data exchange format (XML schema and developer’s table) was not updated during this maintenance cycle. There were no changes made to the Material Classes.

Bisphenol A (BPA) was added to the REACH Candidate List and, given that the substance has several applications in EEE manufacturing, was included in the IEC 62474  DSL.

For the Lead/Lead Compounds entry with ID=00021 a clarification was made to the reportable application field.  There are a total of five different Lead/Lead Compound entries with different reporting thresholds for different reportable applications. The clarification helps ensure that the correct threshold is being applied for each application.

IEC 62474 Declarable Substance List is Updated (June 2016)

The IEC 62474 Declarable Substance List (DSL) and the Reference Substance List (RSL) were updated on June 22, 2016. The substance lists are used globally by EEE manufacturers, suppliers, and IT solution providers as a common list of substances and substance groups that are declared throughout the supply chain. Downstream manufacturers of EEE products need suppliers to declare these substances when they are present in order to determine compliance to substance regulations around the world and as evidence of due diligence in their conformity assessment.

The update includes:

  • the one substance added to the EU REACH Candidate List on June 20, 2016
  • The entry for “Perfluorononan-1-oic-acid and its sodium and ammonium salts” was changed from a substance entry to a substance group and the three substances in this group were added as reference substanc.

The IEC 62474 data exchange format (XML schema and developer’s table) was not updated during this maintenance cycle.

EU REACH Candidate List

Only one substance was added to the REACH Candidate List by the European Chemical Agency (ECHA) on June 20, 2016. The subtance has potential applications in EEE and is therefore included in the DSL.

The substance “Perfluorononan-1-oic-acid and its sodium and ammonium salts” had been added to the DSL in December 2015 as a substance.  However, it’s actually a set of three substances; therefore it’s listing has been changed to a substance group and the three individual substances have been added to the reference substance list.

The new reference substance entries just added are shown in the table below.

IEC 62474 DSL Updated to Align with “Article” Interpretation

The IEC 62474 Declarable Substance List (DSL) was updated (D11.00) on March 28, 2016 to reflect the September 2015 European Court of Justice (ECJ) interpretation of the term “article”. The ECJ ruling is important for OEMS and suppliers in determining whether a REACH Candidate List SVHC is above the 0.1 mass% threshold that triggers communication and notification obligations under the EU REACH regulation. A summary of the ECJ ruling is available from the blog post EU Judgment – SVHC Reporting Required for First Article.

The 71 REACH SVHCs entries in the DSL have had their reporting threshold revised to “0.1 mass% of article” to indicate that the threshold refers to an individual article.

In developing a solution to align the DSL with the ECJ ruling, the IEC 62474 validation team (VT) considered the possibility of using the term “product part” to represent an article; however, a “product part” in a material declaration can be used to represent any of several levels of subassemblies and components in a EEE product. Therefore, in many situations, it may not always be a match for the REACH definition of article.

The VT also discussed the possibility of including some type of guidance to assist manufacturer in using the threshold in the context of electrical and electronic products. However, given that guidance on the practical interpretation of “article” is still the subject of intense discussion by regulators, politicians industry and other stakeholders for the next release of the European Chemical Agency (ECHA) guidance document on substances in articles, it wouldn’t be appropriate for the VT to try to second guess the conclusion of this work.  Once ECHA publishes its guidance document with examples, the IEC 62474 DSL may be revised again to support the guidance.

Reporting Levels

With the ECJ ruling addressed, the new “ReportingLevel” field, which was recently added to the database, was populated.  The ReportingLevel field is intended to simplify for users the interpretation of the more complex reporting thresholds. Some of the reporting thresholds are difficult to interpret because of how they are written in the regulation. For example, some thresholds refer to a part, but the actual intention from the regulation is material.

The ReportingLevel for a  given DSL entry indicates one of four possible values: Product, Product Part, Article or Material.

Changes to Declarable Substance Groups

There were a couple of additional minor DSL changes.

The scope of the substance group “Polychlorinated Naphthalenes (PCNs)” was expanded to include all such substances with 1 or more chlorine atoms Previously only substances with  more than 3 chlorine atoms were consider to be included in the group. The change is based on the additional requirements of the EU POP regulation.

For consistency in substance naming, the substance group  “4-Nonylphenol, branched and linear, ethoxylated [substances with a linear and/or branched alkyl chain with a carbon number of 9 covalently bound in position 4 to phenol, ethoxylated covering UVCB- and well-defined substances, polymers and homologues, which include any of the individual isomers and/or combinations thereof]” was abbreviated to “4-Nonylphenol, branched and linear, ethoxylated” to align with the IEC 62474 substance naming convention. The portion of the  name that appears in square brackets is not actually part of the chemical name but rather a description of the substance group.  This description has been moved to the comment field in the DSL entry.

Reference Substances

Given the expanded scope of the Polychlorinated Naphthalenes (PCNs) substance group, a large number of additional references have been added in place of the generic reference substance “Other polychlorinated Naphthalenes”. The added reference substances are listed in Table 1 below.

Four additional reference substances have been list for the substance group “4-Nonylphenol, branched and linear, ethoxylated”. The new entries are shown in Table 2.

 Material Classes and the XML Schema
