Harmonization Activities on ISO and JIS Standards (Compressibility) for Brake Linings in Japan

A joint taskforce between the Sub-Committee (Brake Linings) of the J-SAE and the Technical Committee (Brake Linings) of the JAPIA from 1999 through 2001 has been conducting actual test runs of “Compressibility of brake linings” based on ISO 6310 and JIS D 4413. The studies on “Compressibility of brake linings” based on ISO and JIS test standards are discussed in this paper and some considerable improvements for these test procedures were obtained through these test studies and actual test runs.
