41、If no properties are specified, the designation would be PPA0121G33.D53360935. Suffixes5.1 When additional requirements are needed for the mate-rials covered in this specification that are not covered in TablesPPA, A, or B, then those requirements shall be designatedthrough the use of suffixes.5.1.1
42、 A list of suffixes found in Classification SystemD 4000 (Table 3) is useful for additional requirements asappropriate.5.2 Flammability callouts were changed in 2007. Thereforecallouts written before 2007 are different from those written in2007 and later.5.2.1 If the requirements for the polyphthala
43、mide materialin 4.3.3 also included flammability requirements, the followingexample illustrates the call-out based on ASTM D 4000-04:PPA0121G33A06577FL34PPA0121G33A06577 = Same as 4.3.3F = Flammability requirementsL=UL94 recognition required3 = UL recognition at 0.80-mm min thickness4 = UL rating 94

Basic Requirements6.1
45、 Basic requirements from Tables PPA and A or B, as theyapply, are always in effect unless these requirements aresuperseded by specific suffix requirements, which always takeprecedence. Properties in Tables A and B supersede propertiesin Table PPA when reinforced or filled materials are specified.7.
46、General Requirements7.1 The material compositions shall be uniform and shallconform to the requirements specified herein.8. Detail Requirements8.1 Test specimens for the various materials shall conformto the requirements prescribed in Tables PPA and A or B, andthe suffix requirements as they apply.8
47、.2 For the purpose of determining conformance, all speci-fied limits in this specification are absolute limits, as defined inPractice E29.8.2.1 With the absolute method, an observed value or acalculated value is not rounded, but is to be compared directlyto the specified limiting value. Conformance
48、or nonconfor-mance with this specification is based on this comparison.9. Sampling9.1 Sampling shall be statistically adequate to satisfy therequirements of 13.4. A lot of material shall be considered as aunit of manufacture as prepared for shipment, and is permittedto consist of two or more “produc
49、tion runs” or batches.10. Specimen Preparation10.1 Mold test specimens by an injection molding process(see Practice D 3641 or ISO 294).
