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 The restriction of BNST (Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene) was repealed by Canada and the DSL entry (ID=00127) was accordingly deleted from the DSL.
|ID||Specific Substance||CAS number||Common Synonyms||Typical Applications||Reportable Applications||Reporting Threshold|
|00148||Benzo[ghi]perylene||191-24-2||Impurities in carbon black, which is used as coloring agent in plastics and softener in rubbers||All||0.1 mass% of article|
|00149||Octamethylcyclotetrasiloxane||556-67-2||D4||Siloxanes are monomers used to manufacture silicones. They may remain as unreacted in silicone polymers and copolymers, used in many electrotechnical equipment product categories.||All||0.1 mass% of article|
|00150||Decamethylcyclopentasiloxane||541-02-6||D5||Siloxanes are monomers used to manufacture silicones. Residuals may remain in silicone polymers and copolymers.||All||0.1 mass% of article|
|00151||Dodecamethylcyclohexasiloxane||540-97-6||D6||Siloxanes are monomers used to manufacture silicones. They may remain as unreacted in silicone polymers and copolymers, used in many electrotechnical equipment product categories.||All||0.1 mass% of article|
|00152||Disodium octaborate||12008-41-2||Wooden veneer sheets and pressed wooden panels (as a constituent within the starch adhesive), as a flame retardant, as stabilizer in aminoplastic resins, and as a biocide in professional and industrial wood preservation.||All||0.1 mass% of article|
|00153||Terphenyl, hydrogenated||61788-32-7||Plasticizers, sealants, epoxy adhesives, paints and heat sinks||All||0.1 mass% of article|
|00154||Lead||7439-92-1||Steel, aluminum and copper alloys, lead acid batteries, solder and other applications||All||0.1 mass% of article|
|00139||Dicyclohexyl phthalate||84-61-7||DCHP||Plasticizer, dye, pigment, paint, ink, manufacture of adhesive, lubricant||All||0.1 mass% of article|
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.
Additions and modifications to the Reference Substance List (RSL) are shown in the Table below.
|Type of Change||ID||Substance Group||Specific Substance||CAS number|
|Deleted||R00099||Cadmium/Cadmium compounds||Cadmium chloride||10108-64-2|
|Deleted||R00100||Cadmium/Cadmium compounds||Cadmium sulfate||10124-36-4, 31119-53-6|
|Deleted||R00103||Chromium (VI) Compounds||Chromium trioxide||1333-82-0|
|Deleted||R00104||Chromium (VI) Compounds||Sodium chromate||7775-11-3|
|Deleted||R00105||Chromium (VI) Compounds||Sodium dichromate||10588-01-9, 7789-12-0|
|Deleted||R00107||Chromium (VI) Compounds||Potassium dichromate||7778-50-9|

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.
