ASTM D1755-92(2001)
(Specification)Standard Specification for Poly(Vinyl Chloride) Resins
Standard Specification for Poly(Vinyl Chloride) Resins
SCOPE
1.1 This specification covers the establishment of requirements for homopolymers of vinyl chloride in original powder form intended for subsequent mixing and processing in thermoplastic compositions. These resins have a nominal specific gravity of 1.4 and a theoretical chlorine content of 56.8%.
1.2 Two types of resin have been recognized: general purpose and dispersion. When mixed with the customary amount of plasticizer, general-purpose resins yield a dry or moist powder while dispersion resins yield a liquid slurry. Since many resins are polymerized to meet special requirements, a system of classification has been provided that permits a wide choice of grades.
1.3 The values stated in SI units are to be regarded as the standard.
Note 1—This standard is similar in content (but not technically equivalent) to ISO 1264-1980.
1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
