MATERIAL DECLARATION FOR PRODUCTS OF AND FOR

THE ELECTROTECHNICAL INDUSTRY
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The electrotechnical industry tracks and declares specific information about the material

composition of its products for compliance and environmentally conscious design

requirements. The electrotechnical industry needs to gather information about the composition

of products and product parts that are purchased from suppliers for incorporation into their

products. Currently material declarations are driven by individual product manufacturer’s

specifications and there is no internationally accepted standardization. This results in

economic inefficiencies. To simplify requirements across the supply chain and to improve

economic efficiencies, it is necessary to standardize the exchange of material composition

data and provide requirements for material declarations.

This International Standard benefits the electrotechnical industry by establishing requirements
for reporting of substances and materials, standardizing protocols, and facilitating transfer
and processing of data.
62474  IEC:2012 – 7 –
MATERIAL DECLARATION FOR PRODUCTS OF AND FOR

THE ELECTROTECHNICAL INDUSTRY
1 Scope
This International Standard specifies the procedure, content, and form relating to material
declarations for products of companies operating in and supplying the electrotechnical

industry. Process chemicals and emissions during product use are not in the scope of this

International Standard.
The main intended use of this International Standard is to provide data to downstream
manufacturers that:
• allows them to assess products against substance restriction compliance requirements
• they can use in their environmentally conscious design process and across all product
life cycle phases
Clause 4 specifies requirements for a material declaration.
Clause 5 specifies the criteria for declarable substances and material classes in the
IEC 62474 database associated with this standard.
Clause 6 specifies the data format and exchange requirements to be included in the
IEC 62474 database.
Clause 7 specifies the process to regularly update and maintain the IEC 62474 database.
Although this International Standard specifies base requirements, it offers flexibility to product
manufacturers and suppliers in the selection of additional requirements or information.
This International Standard does not provide any specific method to capture material
composition data. Organizations have the flexibility to determine the most appropriate method
to capture material composition data without compromising data utility and quality. This
International Standard is intended to allow reporting based on engineering judgment, supplier
material declarations, or on sampling and testing.
2 Normative references

4 Requirements for material declaration
4.1 General
This clause describes the base requirements and additional requirements for a material
declaration. Subclause 4.2 describes the base data requirements and Subclause 4.3

– 10 – 62474  IEC:2012
describes additional requirements, should the manufacturer and supplier agree to declare

more.
Clause 4 is organized in the order of the conceptual diagrams (see Figures 1 and 2) for ease

of understanding. Required information is shown with solid boxes and arrows. Options are

shown within dotted boxes. Product, substance groups or substances with a mandatory

reporting requirement in the IEC 62474 database are mandatory objects in this approach.

Product parts, material classes, materials, and substance groups or substances without a

mandatory reporting requirement in the IEC 62474 database are optional objects in this

approach. Substance groups and substances not listed in the IEC 62474 database are also
optional objects. Further mandatory requirements apply without being displayed in the

diagrams (e.g. mass or mass percent).

4.2 Base data requirements
4.2.1 Products
The following requirements shall apply to products:

a) A material declaration shall be provided for a product or product family.

NOTE 1 Only the supplier is likely to know the appropriate product family groupings for material declaration
purposes based on their technical knowledge of product material content.

b) The product shall have an identification and a mass assigned. In the case of a product

family, the identification and mass of each product within the product family shall be

specified.
NOTE 2 When each product in the product family has the same mass, it is sufficient to provide this mass just
once.
4.2.2 Product parts
Product parts shall be declared if a substance group or substance in the IEC 62474 database
refers to this part in the reporting threshold level and its reporting threshold level is exceeded.
NOTE Examples for such product parts are when batteries are incorporated into a printed circuit board assembly.
If such product parts need to be declared, the following shall apply:
a) Product parts shall be assigned to the product;
b) Product parts shall have an identification assigned;
c) Product parts shall have a mass or percentage of the product mass assigned.
4.2.3 Substances or substance groups listed in the IEC 62474 database with a
mandatory reporting requirement
Substances or substance groups listed in the IEC 62474 database with a mandatory reporting
requirement shall be declared if they are present in the product at or above the reporting
threshold level given in the IEC 62474 database and if the reportable application as listed in

the IEC 62474 database is applicable for that substance or substance group.
NOTE 1 When such substances or substance groups are not declared in a material declaration, they are not
present over the specified threshold, but could be present below this threshold or the reportable application as
listed in the IEC 62474 database is not applicable.
If such substances or substance groups are present above the reporting threshold level given
in the IEC 62474 database and if the reportable application as provided in the IEC 62474
database is applicable, the following requirements shall apply:

a) Such substance groups shall be assigned to the product part (if 4.2.2 applies) or
otherwise to the product. Such substances shall be assigned to the substance group (if
the substance group has a mandatory reporting requirement) or otherwise to the product
part (if 4.2.2 applies) or otherwise to the product.
b) Such substances or substance groups shall be named as given in the IEC 62474 database.
c) In general, such substance groups or substances shall have a mass or percentage of the
product part mass (if 4.2.2 applies) or otherwise a percentage of the product mass
assigned. If such substance groups or substances have reporting threshold levels
specified in the IEC 62474 database, referring to the material, they shall have a material
mass percent assigned.
NOTE 2 The IEC 62474 database lists some substance groups that require reporting as percentage of the
material mass.
NOTE 3 The reporting requirement as percentage of the material mass can differ e.g. the numerator for this
percentage can be the sum of the masses of all substances belonging to this substance group present or just the
mass of a specific element. Details are given in the IEC 62474 database.

– 12 – 62474  IEC:2012
d) Such substance groups and substances with a reporting threshold level in the IEC 62474

database at the material or the product part level shall be declared separately for each

occurrence in the product exceeding the threshold.

4.2.4 Other requirements
The following requirements shall apply to material declarations:

a) Business information that is needed to exchange material declarations shall be provided

(see the IEC 62474 database).
b) In the case that the product manufacturer requests more than base requirements as

specified in this International Standard and the IEC 62474 database, the contracting

parties shall agree to details, such as safeguards protecting supplier trade secrets at the
request of the supplier.
c) The International System of Units (SI) shall be used.
NOTE For the purpose of presentations and communications among computers, the SI units together with
relevant SI prefixes are preferred. For example, small product parts could be best represented in grams rather than
kilograms.
d) If the supplier is uncertain on the applicability of the reportable application to their
product, then the presence of the substance shall be declared if it exceeds the reporting
threshold in the supplied product.
4.3 Additional requirements
4.3.1 Product parts
The following requirements apply to product parts when they are declared:
a) Product parts shall be assigned to another product part (if a higher level product part is
declared) or otherwise to the product.
b) Product parts shall have an identification assigned.
c) Product parts shall have a mass or otherwise the percentage of another product part mass
(if a higher level product part is declared) or otherwise the percentage of the product mass
assigned.
d) For identical product parts occurring multiple times, the information may be given only
once. In this case, the number of identical product parts shall be provided.
4.3.2 Material classes (optional)
The following requirements apply to material classes when declared:
a) Material classes shall be assigned to the product.

b) Material classes shall be named according to the IEC 62474 database.
c) Material classes shall have a mass or percentage of the product mass assigned.
d) The sum of the mass of the declared material classes should represent at least 95 % of
the product mass.
4.3.3 Materials (optional)
The following requirements apply to materials when declared:
a) Materials shall be assigned to a product part (if product part is declared) or otherwise to
the product.
b) Materials should be characterized by names as defined in a standard (e.g., ISO 1043,
parts 1 through 4 for plastics) or by internationally recognized names.
c) Materials shall have a mass or percentage of the product part mass (if product part is
declared) or otherwise percentage of product mass assigned.
d) Materials shall be allocated to material classes as specified in the IEC 62474 database.

62474  IEC:2012 – 13 –
NOTE 1 The definitions to use when determining the material class applicable to a specific material are

contained in the IEC 62474 database.

NOTE 2 When allocating a material to a material class, this does not trigger the conditions of 4.3.2(d)

4.3.4 Substances or substance groups listed in the IEC 62474 database with a

mandatory reporting requirement

Substances or substance groups listed in the IEC 62474 database with a mandatory reporting
requirement shall be declared if they are present in the product at or above the threshold level

given in the IEC 62474 database and if the reportable application as listed in the IEC 62474

database is applicable for that substance or substance group. Substances and substance

groups with a mandatory reporting requirement in the IEC 62474 database may be declared if

they are present in the product below the threshold level given in the IEC 62474 database or
if the reportable application as listed in the IEC 62474 database is not applicable for that
substance or substance group.
NOTE 1 When such substances or substance groups are not declared in a material declaration, they are not
present over the specified threshold, but could be present below this threshold or the reportable application as
listed in the IEC 62474 database is not applicable.
The following requirements apply to such substances or substance groups when declared:
a) Such substance groups shall be assigned to the material (if material is declared), to the
product part (if product part is declared) or otherwise to the product. Such substances
shall be assigned to the substance group (if substance group is declared) or to the
material (if material is declared) or to the product part (if product part is declared) or
otherwise to the product.
b) Such substances or substance groups shall be named as given in the IEC 62474 database.
c) In general, such substance groups or substances shall have a mass or percentage of the
material mass (if material is declared) or a percentage of the product part mass (if product
part is declared) or otherwise a percentage of the product mass assigned. If such
substance groups or substances have reporting threshold levels specified in the
IEC 62474 database, referring to the material they shall have a material mass percent
assigned.
NOTE 2 The IEC 62474 database lists some substance groups that require reporting as percentage of the
material mass.
NOTE 3 The reporting requirement as a percentage of the material mass can differ e.g. the numerator for
this percentage can be the sum of the masses of all substances belonging to this substance group present or
just the mass of a specific element. Details are given in the IEC 62474 database.
d) Such substance groups and substances with a reporting threshold level in the IEC 62474
database at the material or the product part level shall be declared separately for each
occurrence in the product exceeding the threshold.
e) Such substance groups and substances may have information on the reportable

application. If such information is provided, it shall be named as in the IEC 62474
database.
NOTE 4 Reportable applications for all declarable substance groups and substances are listed in the
IEC 62474 database.
NOTE 5 For those substances groups or substances with more than one reportable application, this
information supports the downstream manufacturer in the assessment against substance restriction
compliance requirements.
f) Such substances or substance groups may have information on applicable exemptions
pertaining to the allowed use. If such information is provided, it shall be carried through
the supply chain.
4.3.5 Substances or substance groups listed in the IEC 62474 database with an
optional reporting requirement, as reference substances or substances or
substance groups not listed in the IEC 62474 database
Substances or substance groups listed in the IEC 62474 database with an optional reporting
requirement should be declared if they are present in the product at or above the reporting
threshold level given in the IEC 62474 database and if the reportable application as listed in

– 14 – 62474  IEC:2012
the IEC 62474 database is applicable for that substance or substance group. Substances and

substance groups with an optional reporting requirement in the IEC 62474 database may be

declared if they are present in the product below the reporting threshold level given in the

IEC 62474 database or if the reportable application as listed in the IEC 62474 database is not

applicable for that substance or substance group. Substances listed in the IEC 62474

database as reference substances or substances or substance groups not listed in the

IEC 62474 database may be declared.

The following requirements apply to such substances or substance groups when declared:

a) Such substance groups shall be assigned to the material (if material is declared) or to the

product part (if product part is declared) or otherwise to the product.

Such substances shall be assigned to the substance group (if substance group is
declared), to the material (if material is declared) or to the product part (if product part is
declared) or otherwise to the product.
b) Substances or substance groups with an optional reporting requirement in the IEC 62474
database shall be named as given in the IEC 62474 database. Substances not listed in
the IEC 62474 database shall be identified by an internationally recognized name (e.g.
IUPAC name) and preferably also identified with CAS Registry Number, EC Commission
Number etc. when these are available.
NOTE 1 IUPAC Name: name assigned to a chemical compound according to recommendations by IUPAC
Nomenclature of Organic (or Inorganic) Chemistry. IUPAC is the abbreviation for the International Union of
Pure and Applied Chemistry.
NOTE 2 CAS Registry Number (also referred to as CAS Number): unique numeric identifier assigned by the
Chemical Abstracts Service, a division of the American Chemical Society.
NOTE 3 European Commission Number (also referred to as EC Number, EC-No and EC#): unique numeric
identifier assigned by the Commission of the European Union to chemical substances that are commercially
available within the European Union.
c) Such substance groups or substances shall have a mass or percentage of the material
mass (if material is declared) or percentage of the product part mass (if product part is
declared) or otherwise percentage of the product mass assigned.
d) Such substance groups and substances may have information on the reportable
application. If such information is provided, it shall be named as in the IEC 62474
database.
NOTE 4 Reportable applications for all declarable substance groups and declarable substances are listed in
the IEC 62474 database.
