This specification establishes the classification, requirements, and test methods for extruded and compression molded plates, rods, and tubular bars manufactured from polycarbonate or recycled plastics. This specification does not cover materials used in glazing and signage. Rather, it is intended to be a means of calling out mechanical grade plastic products used for fabrication of end items or parts. The polycarbonate shape products may be categorized by type, grade, and class depending on resin and filler compositions. Appropriately sampled specimens shall be tested and conform accordingly to the following properties: tensile strength at break, elongation at break, and tangent tensile modulus; size and dimensional stability; lengthwise camber and widthwise bow; squareness; flexural modulus; and Izod impact strength.
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
1.1 This specification covers requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded and compression molded plate, rod, and tubular bar manufactured from polycarbonate.
1.2 This specification is not intended to cover materials used in glazing and signage as defined in 3.2.1 and 3.2.6. It is intended to be a means of calling out mechanical grade plastic products used for fabrication of end items or parts as defined in 3.2.2.
1.3 The properties included in this specification are those required for the compositions covered. Requirements necessary to identify particular characteristics important to specialized applications are to be described by using the classification system given in Section 4.
1.4 This specification allows for the use of recycled plastics as defined in Guide D7209.
1.5 The values stated in inch-pound units are to be regarded as the standard in all property and dimensional tables. For reference purposes, SI units are also included in Table S-PC and Table 1 only.
1.6 The following precautionary caveat pertains only to the test method portions, Section 12, 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 1—There is no known ISO equivalent to this standard.
