Scope

This standard specifies the classification and marking system for some of the most commonly used unfilled thermoplastic polymers for sliding bearings.
This standard classifies these unfilled thermoplastic polymers based on their different properties, additives, and the relevant information about their application in sliding bearings. The marking system does not include all characteristics, so polymers with the same marking may not be interchangeable in all cases.
This standard lists some basic parameters that affect the selection of polymers for sliding bearings, and it also outlines the properties and applications of the most commonly used unfilled thermoplastic polymers.
