IS 15151 : 2025/ISO 9982 : 2021 Belt Drives - Pulleys and V-Ribbed Belts for Industrial Applications - PH, PJ, PK, PL and PM Profiles - Dimensions
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO 9982 : 2021 'Belt drives - Pulleys and V-ribbed belts for industrial applications - PH, PJ, PK, PL and PM profiles - Dimensions' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Conveyor Belts Sectional Committee and approval of the Production and General Engineering Division Council.
This 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 except elastic belts.
The PK belt was originally established for automotive accessory drive applications and ISO 9981 deals specifically with that particular field.
This standard was first published in 2002. This revision has been brought out to align the standard with ISO 9982 : 2021.
The major changes in this revision are as follows:
a) Clarifications have been provided where the document is not for elastic belts;
b) Revision of 5.3.6 to reference ISO 254 for pulley roughness has been made;
c) Removal of the current roughness values has been made;
d) Specifications of the maximum pulley groove radius (Table 2) have been provided;
e) Specifications of the minimum pulley groove radius of PH and PJ profiles (Table 2) have been provided;
f) Specifications of the maximum belt groove bottom radius of PH and PJ profiles (Table 8) have been provided; and
g) Specification of the measuring pulleys and measuring forces of PK, PL and PM profiles (Table 9) have been provided.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'.
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
