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.
