Scope

This standard specifies a comprehensive method, for measuring disc brake pads, to
determine dimensional change as a function of temperature and their heat transfer.
Dimensions include:
- Thickness;
- Certain profile dimensions of brake pads, whose variations may lead to brake
failure.
This standard applies to disc brake pads for road vehicles. The dimensions shall not
exceed: width 120 mm, height 80 mm, thickness 20 mm. It shall be the entire molded
or bonded type pads with a solid back plate.
