Scope
1.1 This document establishes a naming system for plasticized polyvinyl chloride (PVC-P) thermoplastic materials, which can serve as a basis for standardization.
1.2 The types of PVC-P plastics are classified according to a classification system. The basis for establishing the classification system is: the level of naming performance and the form of related substances, the intended use and/or processing methods, important performance characteristics, and information on additives and colorants.
Naming performance includes:
a) Shore hardness;
b) Density;
c) Temperature at which torsional stiffness reaches 300 MPa.
