The properties enumeratedin this table and the tests defined provide identification of thecompounds selected. They are not necessarily suitable fordirect application
18、 in design because of differences in shape orpart, size, loading, environmental conditions, method ofprocessing, etc.4.2 Classes are designated by the cell number for eachproperty in the order in which they are listed in Table 1.NOTE 2The manner in which selected materials are identified by thisclas
