scope:

This specification covers the properties of an integrally colored, weatherable and stain resistant when required, PVC (Poly Vinyl Chloride) injection molding compound. These materials can be used for mold-in-color white and light colors or other integral colored PVC. White and some light colors require added stain resistance. All versions, including added stain resistance, will be defined by their ability to meet the test requirements of this specification. They are identified by "Type" and "Grade" to distinguish the Shore Hardness and added stain resistance respectively.
