Performance Testing of PK Section V-Ribbed Belts
The following information covers accessory drive belt testing methods and includes test configurations, pulley diameters, power loads, and guidance for interpreting test data. Belt construction definitions are also documented. This information has been prepared from existing literature, including standards and data supplied by Producers and Users of V-ribbed belts.
This latest revision of SAE J2432 accomplishes the following:
Revised backside pulley sizes in durability tests to properly replicate real world failure modes.
Increased belt dryout time in the noise test to accommodate all belt constructions.
Revise cold temperature tolerance specification to align with the accuracy and calibration limits of the test equipment.
