This specification covers nonrigid vinyl chloride polymer and
copolymer classes in which the resin portion of the composition
contains at least 90 % vinyl chloride. The remaining 10 % can
include one or more monomers copolymerized with vinyl chloride or
consist of other resins mechanically blended with polyvinyl
chloride or copolymers thereof.
These nonrigid vinyl compounds are defined by a hardness range
and include the necessary stabilizers, plasticizers, fillers, dyes,
and pigments to meet the designated requirements.
This specification includes nonrigid vinyl chloride compounds
recommended for compression molding, injection molding, and
extrusion, but it must be recognized that particular compounds are
not suitable for all these means of fabrication.
NOTE 1-This standard and ISO 2898-1 and ISO 2898-2 address the
same subject matter, but differ in technical content.
The values stated in SI units are to be regarded as the
standard. The values given in parentheses are for information
This standard does not purport to address all of the safety
concerns, 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.
The text of this specification references notes and footnotes
which provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered as
requirements of this specification.
Recycle PVC plastics meeting the requirements of this
specification may be used in some applications. Refer to the
specific requirements in the Materials and Manufacture section of
the applicable product standard.
