Terminology3.1 DefinitionsThe terminology used in this classificationsystem is in accordance with Te
20、rminology D883 and Termi-nology D1600.4. Classification4.1 Poly(phenylene sulfide) materials are classified accord-ing to their composition. These classes are subdivided intogrades as shown in the Basic Property Table (Table PPS).NOTE 3An example of the use of this classification system forspecifyin
21、g fiberglass reinforced poly(phenylene sulfide) is given asfollows: The line callout PPS011G40 (specification) indicates the follow-ing:PPS = poly(phenylene sulfide) as found in Terminology D1600.01 = general purpose (group),1 = glass reinforced (class), andG40 = nominal 40 % glass with the requirem
22、ents given in TablePPS (grade).4.1.1 To facilitate incorporation of future or special materi-als the “other” category for group (00), class (0), and grade (0)is shown in Table PPS. The basic properties of these materialsare obtained from Table A as they apply.4.2 Reinforced, filled, and unfilled ver
23、sions of poly(phe-nylene sulfide) materials that are not in Table PPS are specifiedin accordance with Tables PPS, A, and B. Table PPS is firstused to identify the group and class of poly(phenylene sulfide).Table A is then used to specify the property requirements afterthe addition or reinforcements,
24、 pigments, fillers, or lubricantsat the nominal level indicated (see 4.2.1) or Table B is used tospecify the property requirements of unfilled/unreinforcedversions of poly(phenylene sulfide).4.2.1 Reinforced versions of the basic materials are identi-fied by a single letter that indicates the reinfo
25、rcement used andtwo digits that indicate the nominal quantity in percent byweight. Thus, a letter designation G for glass-reinforced and 30for percent of reinforcement, G30, specifies a filled materialwith a nominal glass level of 30 %. The reinforcement letterdesignations and associated tolerance l

The types and percentages of re
28、inforcements andadditives are usually shown on the suppliers technical data sheet unlessthey are proprietary in nature. If necessary, additional callout of thesereinforcements and additives are to be accompanied by use of the suffixpart of the system (see Section 5).4.2.2 Specific requirements for r
29、einforced, filled, or lubri-cated poly(phenylene sulfide) materials shall be identified byusing a six-character line callout. The specification shallconsist of the letter “A” and the five digits comprising the cellnumber for the property requirements in the order as theyappear in Table A.4.2.2.1 Alt
