This International Standard specifies the principal dimensional characteristics of V-ribbed pulley groove profiles, together with the corresponding endless V-ribbed belts, of PH, PJ, PK, PL and PM profiles which are used for general industrial applications.
The PK belt was originally established for automotive accessory drive applications and ISO 9981 deals specifically with that particular field.
