2、ear oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification system covers ASA and AES materi
3、-als, and ASA and AES alloys suitable for injection molding andextrusion. This classification system does not cover recycledASA and AES materials, and recycled ASA and AES alloys.1.2 The properties included in this standard are thoserequired to identify the compositions covered. There may beother re
4、quirements necessary to identify particular character-istics important to specialized applications. These may bespecified 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 outplastic materi
5、als used in the fabrication of end items or parts.It is not intended for the selection of materials. Materialselection should be made by those having expertise in theplastic field after careful consideration of the design and theperformance required of the part, the environment to which itwill be ex
6、posed, the fabrication process to be employed, thecosts involved, and the inherent properties of the material otherthan those covered by this standard.NOTE 1This classification system and ISO 6402 cover the samesubject matter but are not technically equivalent.1.4 The following precautionary caveat
7、pertains only to thetest method portion, Section 11, 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 practices and determ

Terminology3.1 Except for the terms defined below, the terminologyused
16、 in this classification system is in accordance with Termi-nologies D 883 and D 1600.4. 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 examp
17、le of this classification system is given as follows:The designation ASA0111 indicates the following:ASA = acrylonitrilestyreneacrylate, as found in TerminologyD 1600,01 = injection molding resin (group),1 = medium impact (class), and1 = requirements given in Table ASA/AES (grade).4.1.1 To facilitat
18、e incorporation of future or special materi-als, the “other” category for class (0), and grade (0) is shownin Table ASA/AES. The basic properties of these materials canbe obtained from Table A, B, or C as they apply.4.2 Reinforced, filled, and lubricated versions of ASA andAES materials, and ASA and
19、 AES alloys that are not in TableASA/AES are classified in accordance 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 nomina
20、l level indicated (see 4.2.1).4.2.1 Reinforced versions of the basic materials 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,
21、 G33, specifies a filled material witha nominal glass level of 33 %. The 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,sili
22、cone, and molybdenum disulfide)depends upon material andprocessto be specifiedM 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 callou
23、t of the modified basicmaterial. The types and percentages of reinforcements 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
24、of thesystem (see Section 5).4.2.2 Specific requirements for reinforced, 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 th
25、e property requirements inthe order as they appear in Tables A, B, or C. Although thevalues listed are necessary to include the range of propertiesavailable in existing materials, users should not infer that everypossible combination of the properties exists or can be ob-tained.4.2.3 When the grade
26、of the basic material is not known, oris not important, the use of the “o” grade classification 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 f
27、ollowing material requirements:ASA 0120 = Acrylonitrile-styrene-acrylate, molding resin,high impact, from Table ASA/AES,G30 = Glass reinforced at 30 % nominal level,A = Cell Table A property requirements,5 = 80 MPa Tensile Stress at Yield, min,5 = 7500 MPa Modulus of Elasticity in Tension, min,1 = 4
28、 kJ/m2Charpy Impact Strength of Notched Specimens, min,3 = 90C Vicat softening temperature, min, and0 = unspecifiedIf no properties are specified, the designation would be ASA0120G30A00000.5. Suffixes5.1 When additional requirements are needed that are notcovered by the basic requirements or cell-ta
29、ble requirements,they shall be indicated through the use of suffixes.5.2 A list of suffixes can be found in Classification SystemD 4000 (Table 3) and may be used for additional requirementsas appropriate. Additional suffixes will be added to thatstandard as test methods and requirements are develope
30、d andrequested.6. General Requirements6.1 Basic requirements from the property tables or celltables 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.
31、7. Detail Requirements7.1 The materials shall conform to the requirements inTables ASA/AES, A, B, 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 d
32、efined in Practice E 29.7.2.1 With the absolute method, an observed value or acalculated value is 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 therequire
33、ments of 12.4.8.2 A batch or lot shall be constituted as a unit of manufac-ture as prepared for shipment and may consist of a blend of twoor more “production runs.”D6865042TABLE ASA/AES ASA/AES Minimum RequirementsGroup Description Class Description Grade DescriptionVicat SofteningTemperature,C, ISO
