1. Scope

1.1 This specification provides for the identification of polybutylene plastics molding and extrusion materials in such manner that the manufacturer and the purchaser can agree on the acceptability of different lots or shipments. The tests involved in this specification are intended to provide information for identifying materials according to types and categories. It is not the function of this specification to provide specific engineering data for design purposes.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

Note 1--ISO 8986 Part 1 and 2 resembles this standard in title, but the content is significantly different.

1.3 The following safety hazards caveat pertains only to the test methods portion, Section 9, 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
