Abstract
1 Scope This document 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 inheren...
