17、ce with Terminologies D883and D1600.3.2 Definitions of Terms Specific to This Standard:3.2.1 sulfone plastics, nplastics based on any of variousaromatic polymers which contain diphenyl sulfone in thebackbone of the repeating unit of the molecule.3.2.1.1 DiscussionAll of the sulfone polymers which ar

18、eunder this specification contain ether oxygen which is anecessary component of the polymers as in the diphenylsulfone moiety. Examples of moieties which can be part of thebackbone of the repeating unit, in addition to diphenyl sulfone,are diphenyl isopropylidene, and biphenyl. Blends of thesepolyme

19、rs can exist as well as co- and ter-polymers. Commer-cial polymers that are members of this class of thermoplasticsinclude polysulfone (SP), polyether sulfone (PESU), andpolyphenylsulfone (PPSU) (see Fig. 1).4. Classification4.1 Unreinforced sulfone plastics are classified into groupsin accordance w

20、ith their composition. These groups are subdi-vided into classes and grades as shown in Table SP.NOTE 3An example of this classification system is given below. Thespecification SP0213 indicates the following:SP = sulfone plastics as defined in Section 3,02 (Group) = polyether sulfone, as defined in

21、Terminology D1600,1 (Class) = high temperature, and3 (Grade) = requirements given in Table SP.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 SP. The basic properties of these materialscan be obtained fr

22、om Table A as they apply.4.2 Reinforced, filled, and lubricated versions of sulfoneplastics that are in Table SP are classified in accordance withTables 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 re

23、inforcements, pigments,fillers, or lubricants at the nominal level indicated (see 4.2.1).4.2.1 Reinforcements and Additive MaterialsA symbol(single-letter) is used for the major reinforcement or combina-tion, or both, along with two numbers which indicate thepercentage of addition by mass with the t

24、olerances tabulated asfollows:Symbol Material ToleranceC Carbon and graphite fiber reinforced 63%G Glass fiber reinforced 63%L Lubricants Depends upon the materialand processto be speci-fiedM Mineral reinforced 63%R Combination of reinforcements 63%or fillers, or bothNOTE 4This part of the classific

25、ation system uses the 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

26、 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 reinforcement, filled, orlubricated sulfone plastics shall be shown by a six-characterdesignation. The designation will consist of the letter “A” andthe five

27、 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 includethe range of properties available in existing materials, this doesnot imply that every possible combination of the propertiesexists or can be

28、 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 this system.NOTE 5An example of this classification for a reinforced sulfoneplastics material is given as follows. The specificationSP0210G30A43460 would

29、have the following material requirements:SP0210 = poly(ether sulfone) from Table SP,G30 = glass reinforced at the 30 % nominal 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,

Suffixes5.1 When additional requirements are needed for the mate-rials covered in this specification that are not covered in TablesSP or A, then those requirements shall be designated throughthe use of suffixes.5.1.1 A list of suitable su

32、ffixes are found in Table 3 ofClassification D4000.5.2 Flammability callouts were changed in 2007. Therefore,callouts written before 2007 are different from those written in2007 and later.5.2.1 If the requirements for the poly(ether sulfone) materialin 4.2.3 also included flammability requirements,
