Classification4.1 There is currently no group, class, or grade distinctionand no basic property table is given.NOTE 2Where no basic property table

18、 exists, the generic familydesignation will be followed by four zeros, for example: PPS 0000.4.1.1 Table A shall be used to specify the physical propertyrequirements that shall be shown by a six-character designa-tion. The designation shall consist of the letter A and the fivedigits comprising the c

19、ell numbers for the property require-ments in the order as they appear in Table A.4.1.1.1 The values listed are necessary to include the rangeof properties available in existing materials. However, thisdoes not imply that every possible combination of propertiesexists or can be obtained with the cur

20、rent state of technology.4.2 A single letter shall be used to indicate the majorcategory of the reinforcement, along with two numbers thatindicate the percentage of additive(s) by mass, with thetolerances as tabulated in Table 1:TABLE 1 Reinforcement-Filler Symbols and TolerancesCategory Material To

23、signate the modification of the basic material. To facilitatethis designation, the type and percentage of additive can be shown on thesuppliers technical data sheet unless it is proprietary in nature. Ifnecessary, additional requirements shall be indicated by the use of thesuffix part of the system,

24、 as given in Section 5. Special agreements ontolerances may be needed below 5 % levels.NOTE 4An example of this classification system for a poly(phenylenesulfide) material is as follows: The designation ASTM D4067PPS0000G40A42043 would indicate the following material requirementsfrom Table A:PPS0000

25、 = poly(phenylene sulfide) material,G40 = glass-reinforced at 40 % nominal level,A = Table A physical property requirements,4 = tensile strength, min 120 MPa,2 = flexural modulus, min 10 000 MPa,0 = Izod impact strength, unspecified,4 = flexural strength, min 165 MPa, and3 = density, min 1.60 g/cm3.

26、If no properties are specified, the designation would be ASTM D4067PPS0000G40A00000.5. 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. Electrical,flammability or other re

27、quirements shall be designated by theappropriate suffix from Table 3 of Classification SystemD4000.5.1.1 If applicable, heat deflection temperature shall bedesignated using the following suffix:Y = Heat deflection temperature as designated by the follow-ing digits:First Digit1 = Test Method D648, 18
