15、lassified intogroups according to their compositions. These groups aresubdivided into classes and grades, as shown in Basic PropertyTable PPE.NOTE 4An example of this classification system is as follows:The specification ASTM D4349 PPE 0223 would indicate:PPE = polyphenylene ether,02 = polystyrene-m

16、odified material (Group),2 = flame retarded (Class Description), and3 = requirements given in Table PPE.4.1.1 Reinforced, filled, and lubricated versions of PPEmaterials are classified according to the reinforcement used andthe nominal level, by weight percent, of the reinforcement. Thegrade is iden

17、tified by a single letter that indicates the filler orreinforcement used and two digits that indicate the nominalquantity in percent by weight. Thus, a grade containing 15 %glass reinforcement would be indicated by PPE0110 G15. Thiscallout indicates:PPE = polyphenylene ether _ as found in Terminolog

21、lers, and reinforcements to designate the modification of thebasic material. The types and percentages are sometimes shown on thesuppliers technical data sheet. If necessary, additional control of thesecompositional variables can be accomplished using the suffix part of thesystem, Section 5.NOTE 6Ma

22、terials containing reinforcements or fillers, or both, atnominal levels not in multiples of five are included in the nearest gradedesignation. For example, a material with a nominal glass fiber level of33 % is included with Grade G35 as shown in 4.1.1.4.1.1.1 Although the values listed are necessary

36、.2 When the grade of the basic material is not known, or isnot important, the use of “0” grade classification shall be usedfor reinforced materials in this system.NOTE 7An example of this classification system for a reinforcedpolyphenylene ether is as follows: The designation ASTM D4349 PPE210G30A22

37、245 indicates the following material requirements from TableA:PPE 210 = polystyrene-modified polyphenylene ether from Table PPE,G30 = glass-reinforced at nominal 30 % (see 4.2),A = Table A Property requirements,2 = 110C deflection temperature at 1.82 MPa, min,2 = 190C deflection temperature at 0.45

38、MPa, min,2 = 55-MPa tensile strength, min,4 = 5000-MPa flexural modulus, min, and5 = 125-J/m Izod impact, min.If no properties are specified, the designation would be ASTM D4349PPE 210G30A00000.4.3 Table B has been incorporated into this classificationsystem to facilitate the classification of speci

39、al materials whereTable PPE or Table A do not reflect the required properties.Table B shall be used in the same manner as Table A.NOTE 8Mechanical properties of pigmented or colored polyphenyleneether materials can differ from the mechanical properties of naturalpolyphenylene ether material, dependi

40、ng on the choice and concentrationof colorants. The main property affected is ductility, as illustrated by areduction in Izod impact strength and tensile elongation values. If specificproperties of pigmented polyphenylene ether materials are required, aclassification using Table B should be used to

41、designate those properties.NOTE 9An example of a special material using this classificationsystem is as follows: The designation ASTM D4349 PPE0310B54220indicates the following, with the material requirements from Table B:PPE 0310 = polyamide-modified polyphenylene ether from Table PPE,B = Table B P

42、roperty Requirements,5 = 105C deflection temperature at 1.82 MPa, min,4 = 155C deflection temperature at 0.45 MPa, min,2 = 35-MPa tensile strength, min,2 = 1800-MPa flexural modulus, min, and0 = unspecified Izod Impact.4.4 Group 5 has been included in Table PPE to allow linecall-out designation for

43、“recycle” resins. Class and gradesgiven should be used with the property ranges from Table A orB, as appropriate.4.5 Requirements for materials tested using ISO specimendimensions are not covered by this classification system.Classification System D4000 can be used to list propertyrequirements invol

44、ving ISO criteria as long as detailed notesdescribing specimen dimensions, test speeds, and so forth, areincluded.5. Suffixes5.1 When additional requirements are needed and are notcovered by the basic requirements or cell-table requirements,they shall be indicated through the use of suffixes.5.2 A l

45、ist of suffixes, which can be used for additionalrequirements as appropriate , is found in Classification SystemD4000 (Table 3). Additional suffixes will be added to thatstandard as test methods and requirements are developed andrequested.6. General Requirements6.1 Basic requirements from the proper

46、ty 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 requirements pr

47、e-scribed in Tables PPE, A and B, and suffix requirements, asthey apply.7.2 For the purpose of determining conformance with thisclassification systems, all specified limits in this standard areabsolute limits, as defined in Practice E29.7.2.1 With the absolute method, an observed value or acalculate

48、d value is not rounded, but is to be compared directlyto the specified limiting value. Conformance or nonconfor-mance with this classification system is based on this compari-son.8. Sampling8.1 Sampling shall be statistically adequate to satisfy 12.4.8.2 A batch or lot is a unit of manufacture as pr

49、epared forshipment and can consist of a blend of two or more “productionruns.”9. Specimen Preparation9.1 The test specimens shall be injection molded.9.2 Mechanical properties can vary with injection moldingconditions. Drying and molding conditions to be used are listedin Table 2.10.
