(Specification)Standard Specification for and Basis for Specifications for Styrene-Acrylonitrile (SAN) Injection and Extrusion Materials
Standard Specification for and Basis for Specifications for Styrene-Acrylonitrile (SAN) Injection and Extrusion Materials
ABSTRACT
This specification covers unfilled, filled, and reinforced styrene acrylonitrile (SAN) materials suitable for injection molding and extrusion. SAN compounds are typically general-purpose materials used in either molding or extrusion processes or applications. There are currently no group, class, or grade distinctions and no basic property table given. The SAN compounds are produced by the polymerization of the monomers acrylonitrile and styrene. The melt-flow rate, Vicat softening point, heat-deflection temperature, tensile strength at yield, flexural modulus, and glass content shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers unfilled, filled, and reinforced styrene acrylonitrile (SAN) materials suitable for injection molding and extrusion.
1.2 This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastic field only after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this standard.
1.3 The properties included in this standard are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified using the suffixes specified in Section 5.
1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are given for information only.
1.5 The following precautionary 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 1—This standard and ISO 4894-1 and ISO 4894-2 address the same subject matter, but differ in technical content. Although this standard and ISO 4894-1 and ISO 4894-2 differ in approach or detail, data obtained using either are technically equivalent.
