Harmonization Activities on ISO Standards (Internal Shear Strength) for Brake Linings in Japan

A joint taskforce between The Sub-Committee of the J-SAE and the Technical Committee of the JAPIA from 1998 through 2000 has been conducting actual test runs of “Internal shear strength of lining material” based on ISO 6311 and JIS D 4415. The studies on “Internal shear strength” based on ISO and JIS test standards are discussed in this paper and some considerable improvements for these test procedures were obtained through these studies and actual test runs.
