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.

 

 

 

 

 

 

 

 

 

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.
