16、1*A Summary of Changes section appears at the end of this standard.Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.3.2 Definitions of Terms Specific to This Standard:3.2.1 sulfone plastics, nplastics based on any of variousaromatic po
17、lymers which contain diphenyl sulfone in thebackbone of the repeating unit of the molecule.3.2.1.1 DiscussionAll of the sulfone polymers which areunder this specification contain ether oxygen which is anecessary component of the polymers as in the diphenylsulfone moiety. Examples of moieties which c
18、an be part of thebackbone of the repeating unit, in addition to diphenyl sulfone,are diphenyl isopropylidene, and biphenyl. Blends of thesepolymers can exist as well as co- and ter-polymers. Commer-cial polymers that are members of this class of thermoplasticsinclude polysulfone (PSU), polyether sul
19、fone (PESU), andpolyphenylsulfone (PPSU) (see Fig. 1).4. Classification4.1 Unreinforced sulfone plastics are classified into groupsin accordance with their composition. These groups are subdi-vided into classes and grades as shown in Table SP.NOTE 3An example of this designation system is given belo
20、w. Thedesignation SP0213 indicates the following:SP = sulfone plastics as defined in Section 3,02 (Group) = polyether sulfone, as defined in Terminology D 1600,1 (Class) = high temperature, and3 (Grade) = minimum requirements given in Table SP.4.1.1 To facilitate incorporation of future or special m
21、ateri-als the “Other” category for group (00), class (0), and grade (0)is shown in Table SP. The basic properties of these materialscan be obtained from Table A as they apply.4.2 Reinforced, filled, and lubricated versions of sulfoneplastics that are in Table SP are classified in accordance withTabl
22、es SP and A. Table SP is used to specify the group ofsulfone plastics and Table A is used to specify the propertyrequirements after the addition of reinforcements, pigments,fillers, or lubricants at the nominal level indicated (see 4.2.1).4.2.1 Reinforcements and Additive MaterialsA symbol(single-le
23、tter) is used for the major reinforcement or combina-tion, or both, along with two numbers which indicate thepercentage of addition by mass with the tolerances tabulated asfollows:Symbol Material ToleranceC Carbon and graphite fiber reinforced 63%G Glass fiber reinforced 63%L Lubricants Depends upon
24、 the materialand processto be speci-fiedM Mineral reinforced 63%R Combination of reinforcementsor fillers, or both63%NOTE 4This 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 reinfo
25、rcements and additivesshould be shown on the suppliers technical data sheet unless they areproprietary in nature. If necessary, additional callout of these reinforce-ment and additives can be accomplished by use of the suffix part of thesystem (see Section 5).4.2.2 Specific requirements for reinforc
26、ement, filled, orlubricated sulfone plastics shall be shown by a six-characterdesignation. The designation will consist of the letter “A” andthe five digits comprising the cell numbers for propertyrequirements in the order as they appear in Table A.4.2.2.1 Although the values listed are necessary to
27、 includethe range of properties available in existing materials, usersshould not infer that every possible combination of theproperties exists or can be obtained.4.2.3 When the grade of the basic material is not known, oris not important, the “0” grade shall be used for the reinforcedmaterials in th
28、is system.NOTE 5An example of this classification for a reinforced sulfoneplastics material is given as follows. The designation SP0213G30A43460would have the following material requirements:SP0213 = poly(ether sulfone) with minimum requirements given in Table SP,G30 = glass reinforced at the 30 % n
29、ominal level,A = Table A property requirements,4 = tensile strength, 95 MPa min,3 = flexural modulus, 4.5 GPa min,4 = Izod impact, 50 J/m min,6 = deflection temperature, 200C min, and0 = unspecified.If no properties are specified, the designation would beSP0213G30A00000.5. Suffixes5.1 Suffixes that
30、may be used are listed in Table 3 ofClassification D 4000.5.2 If the requirements for the poly(ether sulfone) materialin 4.2.3 also included flammability requirements, the followingexample indicates the callout:SP0213G30A43460FL310SP0213G30A43460 = same as in 4.2.3.From Table 3 in Classification D 4
31、000 the following is obtained:F = flammability requirements,L = UL94 recognition required,3 = 0.8 mm minimum thickness,1 = vertical burn test, and0 = V-0 rating.6.
