2、adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense
3、.1. Scope*1.1 This classification system covers only ABS materialsand ABS alloys suitable for injection molding and extrusion.Some of these compositions may also be suitable for compres-sion molding. Recycle ABS and alloys will be addressed in aseparate standard.1.2 This classification system is not
4、 intended for the selec-tion of materials, but only as a means of calling out materialsto be used in the manufacture of parts. Materials are to beselected by personnel with expertise in the plastics field wherethe economics, the environment to be encountered, the inherentproperties of the materials,
5、 the part design, the part perfor-mance required, and the manufacturing process to be employedall enter into the selection.1.3 The properties included in this classification system arethose required to identify the compositions covered. There maybe other requirements necessary to identify particular
6、 charac-teristics important to specialized applications. These will beagreed upon between the user and the supplier by using thesuffixes given in Section 5.1.4 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.5 The following p
7、recautionary caveat pertains only to thetest methods portion, Section 12, of this classification system:This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth
