Historical (view previous versions of standard)
This specification covers rigid poly(vinyl chloride) (PVC) compounds and chlorinated poly(vinyl chloride) (CPVC) compounds for use in extruded or molded form like pipe and fitting applications. Classification requirements for identifying rigid PVC and CPVC shall be according to base resin, impact resistance under notch, tensile strength, modulus of elasticity in tension, deflection temperature under load, and flammability. PVC and CPVC shall be in the form of cubes, granules, free-flowing powder blends, or compacted powder blends, and shall be of uniform size and free of foreign matter. The material shall conform to the test requirements such as tensile strength and modulus of elasticity, conditioning, impact resistance, deflection temperature, and flammability.
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.
1.1 This specification covers rigid PVC and CPVC compounds intended for general purpose use in extruded or molded form
Note 1—Selection of specific compounds for particular end uses or applications requires consideration of other characteristics such as thermal properties, optical properties, weather resistance, etc. Specific requirements and test methods for these properties should be by mutual agreement between the purchaser and the seller.
Note 2—Selection of compounds for pressure piping applications requires consideration of material stress ratings that are required for determining pressure ratings, but are not addressed in this specification. Requirements for long-term material stress ratings in accordance with recognized stress rating standards, such as HDB in accordance with Test Method D2837 for pressure piping, should be included in specifications for pressure piping products or systems.
Note 3—The list of compounding ingredients in 1.1 is not meant to be an exhaustive list of allowable compound ingredients. In addition to the compounding ingredients listed, others may also be used. The list of compounding ingredients in 1.1 does not imply that every ingredient listed is a required ingredient. Some compounds may not contain all the ingredients listed in 1.1.
1.2 For applications involving special chemical resistance see Classification D5260.
1.3 The requirements in this specification are intended for the quality control of compounds used to manufacture finished products. These properties are based on data obtained using standard test specimens tested under specified conditions. They are not directly applicable to finished products. See the applicable ASTM standards for requirements for finished products.
1.4 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.
1.5 Rigid PVC recycle 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.
1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.7 The following safety hazards caveat pertains only to the test methods portion, Section 11, of this specification: 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. Note 4—This specification is similar in content (but not technically equivalent) to ISO 1163-1:1985 and ISO 1163-2:1980.
Note 4—This specification is similar in content (but not technically equivalent) to ISO 1163-1:1985 and ISO 1163-2:1980.
