The following bibliographic material is provided to assist you with your purchasing decision:


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 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.)

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.
