16、ies D883 and D1600.4. Classification4.1 ASA and AES materials, and ASA and AES alloys areclassified into groups according to their composition. Thesegroups are subdivided into classes and grades as shown inTable ASA/AES.NOTE 2An example of this classification system is given as follows:The designati
17、on ASA0111 indicates the following:ASA = acrylonitrilestyreneacrylate, 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 materi-als, the “other” catego
18、ry for class (0), and grade (0) is shownin Table ASA/AES. The basic properties of these materials areobtained from Table A, B, or C as they apply.4.2 Reinforced, filled, and lubricated versions of ASA andAES materials, and ASA and AES alloys that are not in TableASA/AES are classified in accordance
19、with Table A, B, or C.Table ASA/AES is used to specify the group of the materialand Table A, B, or C is used to specify the property require-ments after the addition of reinforcements, pigments, fillers, orlubricants at the nominal level indicated (see 4.2.1).4.2.1 Reinforced versions of the basic m
20、aterials are identi-fied by a single letter that indicates the reinforcement used andtwo digits that indicate the nominal quantity in percent byweight. Thus, a letter designation G for glass-reinforced forpercent of reinforcement, G33, specifies a filled material witha nominal glass level of 33 %. T
21、he reinforcement letterdesignations and associated tolerance levels are shown in thefollowing table:Symbol Material ToleranceC carbon and graphite fiber reinforced 62%G glass-reinforced 62%L lubricants (such as PTFE, graphite,silicone, and molybdenum disulfide)depends upon material andprocessto be s
22、pecifiedM mineral-reinforced 62%R combinations of reinforcements orfillers, or both63% for total reinforcementlevelNOTE 3This part of the classification system uses the percent ofreinforcements or additives, or both, in the callout of the modified basicmaterial. The types and percentages of reinforc
23、ements and additivesshould be shown on the suppliers technical data sheet unless they areproprietary in nature. If necessary, additional callout of these reinforce-ments and additives can be accomplished by use of the suffix part of thesystem (see Section 5).4.2.2 Specific requirements for reinforce
24、d, filled, or lubri-cated ASA and AES materials, and ASA and AES alloys shallbe shown by a six-character designation. The designation willconsist of the letter “A,” “B,” or “C” and the five digitscomprising the cell numbers for the property requirements inthe order as they appear in Tables A, B, or
25、C. Although thevalues listed are necessary to include the range of propertiesavailable in existing materials, not every possible combinationof the properties exists or can be obtained.4.2.3 When the grade of the basic material is not known, oris not important, the use of the “0” grade classification
26、 shall beused for the reinforced materials in this system.NOTE 4An example of this classification for a reinforced ASA/AESmaterial is given as follows. The designation ASA 0120G30A55130would indicate the following material requirements:ASA 0120 = Acrylonitrile-styrene-acrylate, molding resin,high im

Suffixes5.1 When additional requirements are needed that are notcovered by the basic requirements or cell-table requirements,they shall be indicated through the use of suffixes.5.2 A list of suffixes can be
29、 found in Classification SystemD4000 (Table 3) and are to be used for additional requirementsas appropriate. Additional suffixes will be added to thatstandard as test methods and requirements are developed andrequested.6. General Requirements6.1 Basic requirements from the property tables or celltab
30、les are always in effect unless superseded by specific suffixrequirements, which always take precedence.6.2 The plastics composition shall be uniform and shallconform to the requirements specified herein.7. Detail Requirements7.1 The materials shall conform to the requirements inTables ASA/AES, A, B
31、, C, and suffix requirements as theyapply.7.2 For purposes of determining conformance, all specifiedlimits for a specification (line callout) based on this classifica-tion system are absolute limits, as defined in Practice E29.7.2.1 With the absolute method, an observed value or acalculated value is
32、 not rounded, but is to be compared directlywith the limiting value. Conformance or nonconformance isbased on this comparison.8. Sampling8.1 Sampling shall be statistically adequate to satisfy therequirements of 12.4.8.2 A batch or lot shall be constituted as a unit of manufac-ture as prepared for s
