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 % may include one or more monomers copolymerized with vinyl chloride or consist of other resins mechanically blended with polyvinyl chloride or copolymers thereof. The identification of vinyl chloride polymers shall be in accordance with the specified terminology. Material shall be of uniform composition and be so compounded as to meet the requirements designated for it. Nonrigid vinyl chloride plastics ordinarily are supplied in either diced or granulated form. Durometer hardness, specific gravity, tensile strength, volatile loss, brittleness temperature, burning rate, and volume resistance shall be tested to meet the requirements specified.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Significance and Use
6.1 Means for selecting and identifying nonrigid vinyl chloride compounds are provided in Table 1. The properties enumerated in this table and the tests defined are expected to provide identification of the compounds selected. They are not necessarily suitable for direct application in design because of differences in shape of part, size, loading, environmental conditions, etc. Only when specimens are molded in accordance with 11.1.1 can comparative data be expected. The tests selected can also be used for inspection or quality control provided that they are performed strictly in accordance with the instructions given herein and in the designated methods so that extraneous variables are minimized and results are reproduced within the limits of variability of the material being examined and of the tests used for its examination.
1.1 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.
1.2 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.
1.3 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.
—This standard and ISO 2898-1 and ISO 2898-2 address the same subject matter, but differ in technical content.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 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.
1.6 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.
1.7 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.
