Terminology3.1 DefinitionsThe terminology used in this classificationsystem is in accordance with Terminologies D 883 and D 1600.4. Classification4.1 Poly(phenylene sulfide) materials are classified accord-ing to t
20、heir composition. These classes are subdivided intogrades as shown in the Basic Property Table (Table PPS).NOTE 3An example of this classification system for fiberglass rein-forced poly(phenylene sulfide) is given as follows: The designationPPS011G40 indicates the following:PPS = poly(phenylene sulf
21、ide) as found in Terminology D 1600.01 = general purpose (group),1 = glass reinforced (class), andG40 = nominal 40 % glass with the requirements 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
22、 shown in Table PPS. The basic properties of these materialscan be obtained from Table A as they apply.4.2 Reinforced, filled, and unfilled versions of poly(phe-nylene sulfide) materials that are not in Table PPS are classifiedin accordance with Tables PPS, A, and B. Table PPS is firstused to specif
23、y the groups and class of poly(phenylene sulfide).Table A then is used to specify the property requirements afterthe addition or reinforcements, pigments, fillers, or lubricantsat the nominal level indicated (see 4.2.1) or Table B is used tospecify the property requirements of unfilled/unreinforcedv
24、ersions of poly(phenylene sulfide).4.2.1 Reinforced versions of the basic materials are identi-fied by a single letter than indicates the reinforcement used andtwo digits that indicate the nominal quantity in percent byweight; thus, a letter designation G for glass-reinforced and 30for percent of re
25、inforcement, G30, specifies a filled materialwith a nominal glass level of 30 %. The reinforcement letterdesignations and associated tolerance levels are shown asfollows:Symbol Material Tolerance (Based on Total Mass)C carbon and graphite fiber rein-forced62 percentage pointsG glass-reinforced 63 pe
26、rcentage pointsL lubricants (such as PTFE,graphite, silicone)depends upon material and process.to be specified by supplier/useragreement.M mineral-reinforced 63 percentage pointsR combinations of reinforcementsor fillers, or both63 percentage pointsNOTE 4This part of the classification system uses t
27、he percent ofreinforcements or additives, or both, in the callout 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-me
28、nts and additives can be accompanied by use of the suffix part of thesystem (see Section 5).4.2.2 Specific requirements for reinforced, filled, or lubri-cated poly(phenylene sulfide) materials shall be shown by asix-character designation. The designation will consist of theletter “A” and the five di
29、gits comprising the cell number for theproperty requirements in the order as they appear in Table A.4.2.2.1 Although the values listed are necessary to includethe range of properties available in existing materials, usersshould not infer that every possible combination of theproperties exists or can
30、 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 shall beused for the reinforced materials in this system.NOTE 5An example of this classification for a reinforced PPSmaterial is given as follows. The designation PPS0110
31、G20A31042 wouldindicate the following material requirements:PPS0110 = Glass reinforced poly(phenylene sulfide), from TablePPS,G20 = Glass reinforced at 20 % nominal,A = Table A property requirements,3 = 110 mPa tensile strength, min,1 = 6000 mPa flexural modulus, min,0 = Unspecified Izod strength,4
32、= 160 mPa flexural strength, min, and2=1.53 103kg/m3density, min.If no properties are specified, the designation would be PPS010G20A00000.NOTE 6An example of this classification for a unfilled/unreinforcedPPS material is given as follows. The designation PPS000B32030 wouldindicate the following mate
33、rial requirements:PPS000 = unfilled/unreinforced poly(phenylene sulfide), from TablePPS,B = Table B property requirements,3 = 60 mPa flexural modulus, min,2 = 2000 mPa flexural modulus, min,0 = unspecified Izod strength,3 = 80 mPa flexural strength min, and0 = unspecified.If no properties are specif
34、ied, the designation would be PPS0000B00000.5. 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.5Available from Underwriters Laboratories (UL), Corporate Progress, 333Pfing

36、3580625.2 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 developed andrequested.6. General Requirements6.1 Basic requirements fr
37、om 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.7. Detail Requirements7.1 The materials shall conform to the re
38、quirements in TablePPS, A, and B, and suffix requirements as they apply.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.With the absolute method, an observed value
39、 or a calculatedvalue is not rounded, but is to be compared directly with thelimiting value. Conformance or nonconformance is based onthis comparison.8. Sampling8.1 Sampling shall be adequate statistically to satisfy therequirements of 12.4.8.2 A batch or lot shall be constituted as a unit of manufa
