20、nology D 883 and abbreviations with Terminology D 1600unless otherwise indicated.4. Classification4.1 Means for selecting and identifying rigid PVC andCPVC compounds are provided in Table 1. The propertiesenumerated in Table 1 and the tests defined are expected toprovide identification of the compou
21、nds selected. They are notnecessarily suitable for direct application in design because ofdifferences in shape of part, size, loading, environmentalconditions, etc.4.2 Classes are designated by the cell number for eachproperty in the order in which they are listed in Table 1.NOTE 4The manner in whic
22、h selected materials are identified by thisclassification system is illustrated by a Class 12454 rigid PVC compoundhaving the following requirements (see Table 1).
