Terminology3.1 The terminology used in this classification system is in accordance with Terminologies D883 and D1600.4. Classification4.1 ASA and AES materials, and ASA
19、 and AES alloys are classified into groups according to their composition. These groupsare subdivided into classes and grades as shown in Table ASA/AES.NOTE 2An example of this classification system is given as follows:The designation ASA0111 indicates the following:ASA = acrylonitrilestyreneacrylat
20、e, as found in TerminologyD1600,01 = injection molding resin (group),1 = medium impact (class), and1 = requirements given in Table ASA/AES (grade).4.1.1 To facilitate incorporation of future or special materials, the “other” category for class (0), and grade (0) is shown in TableASA/AES. The basic p
21、roperties of these materials are obtained from Table A, B, or C as they apply.4.2 Reinforced, filled, and lubricated versions of ASA and AES materials, and ASA and AES alloys that are not in TableASA/AES are classified in accordance with TableA, B, or C.

22、the material and TableA, B, or C is used to specify the property requirements after the addition of reinforcements, pigments, fillers, or lubricants at thenominal level indicated (see 4.2.1).4.2.1 Reinforced versions of the basic materials are identified by a single letter that indicates the reinfor
23、cement used and twodigits that indicate the nominal quantity in percent by weight. Thus, a letter designation G for glass-reinforced for percent ofreinforcement, G33, specifies a filled material with a nominal glass level of 33 %. The reinforcement letter designations andassociated tolerance levels

If necessary, additional callout of these reinforcements and additives can be accomplished by use of the suffix part of thesystem (see Section 5).4.2.2 Specific requirements for reinforced, filled, or lubricatedASAandAES materials

The designation will consist of the letter “A,” “B,” or “C” and the five digits comprising the cellnumbers for the property requirements in the order as they appear in Tables A, B, or C.

Additional suffixes will be added to that standard as test methods and
34、 requirements are developed and requested.6. General Requirements6.1 Basic requirements from the property tables or cell tables are always in effect unless superseded by specific suffixrequirements, which always take precedence.6.2 The plastics composition shall be uniform and shall conform to the r
