Abstract

This specification covers styrene-maleic anhydride materials suitable for molding and extrusion. It does not however apply to alloys or blends of styrene-maleic anhydride materials with non-elastomeric thermoplastics. The materials shall be conditioned and tested for physical and mechanical properties in the standard laboratory atmosphere. Test specimens and testing parameters for the unreinforced and reinforced, filled, or lubricated materials shall conform to the tensile strength, flexural modulus, Izod impact strength, Vicat softening point, and heat deflection temperature requirements.

Scope

1.1 This specification covers styrene-maleic anhydride materials suitable for molding or extrusion. This specification does not apply to alloys or blends of styrene-maleic anhydride materials with non-elastomeric thermoplastics. Styrene-maleic anhydride materials, being thermoplastic, are reprocessable and recyclable. This specification allows for the use of those materials provided that all the specific requirements of this specification are met.

1.2 The properties included in this standard 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 as given in Section .

1.3 This classification system and subsequent line call out (specification) are intended to provide means of calling out properties of plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Materials should be selected by those having expertise in the plastics field 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, costs involved, and the inherent properties of the material other than those covered by this classification system.

1.4 The values stated in SI units are to be regarded as the standard.

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

There is no equivalent or similar ISO standard for S/MA.
