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


This specification covers acrylonitrile-styrene-acrylate (ASA) and acrylonitrile-EPDM-styrene (AES) plastics and alloys suitable for injection molding and extrusion. ASA and AES materials, and ASA and AES alloys are classified into groups according to their composition. These groups are subdivided into classes and grades: class 0, 1, 2, and 3; grade 0, 1, 2, 3, 4, and 5. The tensile stresses at yield, modulus of elasticity in tension, charpy impact strength, vicat softening temperature, and melt volume-flow rate shall be tested to meet the requirements prescribed.

ORDER

Scope

1.1 This classification system covers ASA and AES materials, and ASA and AES alloys suitable for injection molding and extrusion. This classification system does not cover recycled ASA and AES materials, and recycled ASA and AES alloys.

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 may be specified by using the suffixes as given in Section 5.

1.3 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 should be made by those having expertise in the plastic 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, the costs involved, and the inherent properties of the material other than those covered by this standard.

Note 1—This classification system and ISO 6402 cover the same subject matter but are not technically equivalent.

1.4 The following precautionary caveat pertains only to the test method portion, Section , of this classification system: 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 requirements prior to use.
