ASTM D3935-94(2001)

Standard Specification for Polycarbonate (PC) Unfilled and Reinforced Material

SCOPE
1.1 This specification covers unfilled and reinforced polycarbonate and polycarbonate copolymer materials suitable for injection molding, blow molding, and extrusion. Some of these compositions may also find use for compression molding or application from solution.
1.2 The properties in this specification are those required for identifying the compositions covered. There may be other requirements necessary for identifying particular characteristics important to specific applications. Those may be specified by using the suffixes in accordance with Section 5.
1.3 The values stated in SI units are to be regarded as the standard.
Note 1—This specification is similar to ISO 7391 - 1987 in title only. The technical content is significantly different.
1.4 The following hazards caveat pertains only to the test methods portion, Section 12, of this specification. This standard does not purport to address all 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 or regulatory limitations prior to use.
