Depending upon both thenature and duration o

9、f subsequent handling, it may discolor. Therefore, a rigidspecification for color is impractical and for many uses it may be unnecessary. Inthose cases where such a specification is required, its magnitude will vary widelywith the intended usage. The required value may be measured using Test MethodD
