Frequently Asked Questions
ICS 29.160.10 is a classification code in the International Classification for Standards (ICS) system. It covers "Components for rotating machines". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 33 standards classified under ICS 29.160.10 (Components for rotating machines). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.
IEC 60413:2026 concerns graphite-based grades that are used for sliding electrical contacts, such as carbon brushes or pantograph strips. By extension, it is possible to apply the test procedures of this document to all electrical sliding contacts for electrical transmission appliances and to other appliances of graphite-based materials (heat exchangers, bearings, etc.). This document specifies uniformized procedures for determining their following properties: - density and porosity; - resistivity; - flexural strength; - hardness; - ash content. In addition, it provides recommendations on test procedures for other properties: - Mechanical properties: Charpy impact test, compressive strength, tensile strength (Annex B). - Thermal properties: coefficient of thermal expansion, specific heat capacity, thermal conductivity (Annex C). The properties determined by these tests are inherent to the graphite-based materials and it is therefore important to distinguish them from performance characteristics in operation on electrical equipment (carbon brush in an electrical rotating machine, contact strips on a pantograph, etc.). Since these materials are generally brittle, porous materials, it is reasonable that their properties vary much more than the same properties in metals. Some test methods are suitable for use in production quality control (routine tests), others only for more thorough investigations, using precise laboratory techniques (see Annex A). WARNING — The use of this document can involve hazardous substances, operations and equipment. It does not purport to address all of the safety or environmental problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This second edition cancels and replaces the first edition published in 1972. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Title modified. b) Addition of definitions in Clause 3. c) Clause 5 on test specimen: Nomenclature and addition of the different types of test specimen, specification on their dimensions, tolerances and preparation. d) Improvement of test procedures of the properties already disclosed in the previous edition (Clause 6 to Clause 11). e) Separation of apparent density and apparent porosity (respectively Clause 6 and Clause 10). f) Resistivity (Clause 7): Addition of the eddy current method. g) Rebound hardness (Clause 9): Addition of a new model of scleroscope and addition of Leeb method, as a possible alternative to the traditional scleroscope method. h) Common elements of the test report in a dedicated Clause 12. i) Addition of Annex A (normative): introduction of tests categories (serial/type tests), list of properties to be tested for each test category of test according to their purpose. j) Addition of Annex B: test procedures for other mechanical properties than flexural strength and hardness: tensile, compressive and impact strength. k) Addition of Annex C: test procedures for thermal properties (coefficient of linear expansion, specific heat capacity and thermal conductivity). l) Addition of Annex D: supplement to density and porosity. m) Addition of Annex E: recommendations on methods for elements analysis. n) Addition of Annex F: supplem

IEC TS 63573-1:2026, which is a Technical specification, defines specific requirements for materials to be used for the stator and/or rotor core of rotating electrical machines according to the IEC 60034 series. This document applies in addition to IEC 60404- series and is addressed to the suppliers of the raw material (electrical sheet), to producers of magnetic cores (including a possible annealing treatment), to electric motor manufacturers as well as to users of electrical steel. This document does not apply to motor customers.
The objective of this document is to address the immediate needs of motor manufacturers striving to achieve high IEC efficiency classes.
IEC TS 63573 is an independent product-specific specification focusing on rotating electrical machines in accordance with the IEC 60034 series and can be applied as a supplement to IEC 60404-8-4.
At the time of publication of this document it is anticipated that collaboration with IEC Technical Committee 68 (Magnetic alloys and steels) will lead to the development of Amendment 2 to IEC 60404-8-4:2022. This amendment is expected to clarify the relevant issues and provide a comprehensive solution.
This Technical Specification will be withdrawn once Amendment 2 to IEC 60404-8-4:2022 is published and takes effect, provided it addresses the identified need.

SIGNIFICANCE AND USE
3.1 Resistance or voltage values alone do not provide sufficient detail for an engineering evaluation of contact noise. This practice lists the test conditions that should be reported with noise measurements and indicates some conditions (open circuit voltages, currents, etc.) that have been used for quality control and research studies. The use of these practices should provide sufficient detail for an engineering interpretation of the noise data and allow the tests to be repeated by another laboratory.
SCOPE
1.1 This practice describes the practices and factors considered to be most important in the measurement of electrical contact noise of sliding contacts.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

IEC 60413:2026 concerns graphite-based grades that are used for sliding electrical contacts, such as carbon brushes or pantograph strips. By extension, it is possible to apply the test procedures of this document to all electrical sliding contacts for electrical transmission appliances and to other appliances of graphite-based materials (heat exchangers, bearings, etc.). This document specifies uniformized procedures for determining their following properties:
- density and porosity;
- resistivity;
- flexural strength;
- hardness;
- ash content.
In addition, it provides recommendations on test procedures for other properties:
- Mechanical properties: Charpy impact test, compressive strength, tensile strength (Annex B).
- Thermal properties: coefficient of thermal expansion, specific heat capacity, thermal conductivity (Annex C).
The properties determined by these tests are inherent to the graphite-based materials and it is therefore important to distinguish them from performance characteristics in operation on electrical equipment (carbon brush in an electrical rotating machine, contact strips on a pantograph, etc.). Since these materials are generally brittle, porous materials, it is reasonable that their properties vary much more than the same properties in metals. Some test methods are suitable for use in production quality control (routine tests), others only for more thorough investigations, using precise laboratory techniques (see Annex A).
