Standard Specification for Styrene-Acrylonitrile (SAN) Injection and Extrusion Materials
|Publication Date:||10 July 2000|
|ICS Code (Thermoplastic materials):||83.080.20|
1.1 This specification covers unfilled, filled, and reinforced styrene acrylonitrile (SAN) materials suitable for injection molding and extrusion.
1.2 This specification is not intended for the selection of materials, but only as a means of calling out materials to be used in the manufacture of parts. Materials are to be selected by personnel with expertise in the plastics field where the economics, the environment to be encountered, the inherent properties of the materials, the part design, the part performance required, and the manufacturing process to be employed all enter into the selection.
1.3 The properties included in this specification are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized applications. These will be agreed upon between the user and the supplier, by using the suffixes specified in Section 7.
1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are given for information only. (see IEEE/ASTM SI 10.)
1.5 The following precautionary caveat pertains only to the test methods portion, Section 15, 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-- Although this specification and ISO 4894/1 differ in approach or detail, data obtained using either are technically equivalent.
