Terminology3.1 DefinitionsDefinitions are in accordance with Termi-nology D 883 and abbreviations with Terminology D 1600unless otherwise indicated.4. Classification4.1 Means for selecting and identifying rigid PVC andCPVC compounds are pr
18、ovided in Table 1. The propertiesenumerated in Table 1 and the tests defined are expected toprovide identification of the compounds selected. They are notnecessarily suitable for direct application in design because ofdifferences in shape of part, size, loading, environmentalconditions, etc.4.2 Clas
19、ses are designated by the cell number for eachproperty in the order in which they are listed in Table 1.NOTE 3The manner in which selected materials are identified by thisclassification system is illustrated by a Class 12454 rigid PVC compoundhaving the following requirements (see Table 1). The two-
20、digit cell limits10 and 11 are rarely used, only for special high-temperature grades ofCPVC compound:NOTE 4The cell-type format provides the means for identification andclose characterization and specification of material properties, alone or incombination, for a broad range of materials. This type
21、format, however, issubject to possible misapplication since unobtainable property combina-tions can be selected if the user is not familiar with commercially availablematerials. The manufacturer should be consulted.4.3 Product application chemical resistance when specifiedshall be classified in acco
22、rdance with the classification sectionof Classification D 5260.5. Ordering Information5.1 The purchase order, or inquiry, for these materials shallstate the specification number and identify the class selected,for example, D 1784, Class 12454.5.2 Further definition, as may be required for the follow
23、ing,shall be on the basis of agreement between the purchaser andthe seller:5.2.1 Physical form and particle size (see 6.1),5.2.2 Contamination level (see 6.2),5.2.3 Color (see 6.3),5.2.4 Other supplementary definition if necessary, and5.2.5 Inspection (see 12.1).6. Materials and Manufacture6.1 Mater
24、ials supplied under this specification shall be PVCand CPVC compounds in the form of cubes, granules, free-flowing powder blends, or compacted powder blends.6.2 Materials shall be of uniform composition and size andshall be free of foreign matter to such level of contamination asmay be agreed upon b

27、d.8. Sampling8.1 A batch or lot shall be considered as a unit of manufac-ture and may consist of a blend of two or more production runsof material.8.2 Unless otherwise agreed upon between the seller and thepurchaser, the material shall be sampled in accordance with theprocedure described in the Gene
28、ral and Specific SamplingProcedures, as applicable, of Practice D 1898. Adequate statis-tical sampling prior to packaging shall be considered anacceptable alternative.9. Conformance Testing9.1 The minimum properties identified by the class desig-nations in Table 1 specified in the purchase order (se
29、e 5.1) shallbe verified by the tests described in Section 11.9.2 Conformance with this specification shall be determinedwith one set of test results. If there are multiple test results, theaverage value for all test samples shall be used to determinedconformance.9.3 If the average test value produce
30、s values below theminimum property values of the Class designation in Table 1,the material does not conform to this specification.10. Specimen Preparation10.1 Compliance with the designated requirements chosenfrom Table 1 shall be determined with compression-molded,extruded, or injection-molded test
31、 specimens for Izod impactresistance, tensile strength, tensile modulus of elasticity, de-flection temperature under load, and flammability. Specimenscut from laminates of compression-molded or extruded sec-tions (see Practice D 4703) shall not be used unless it can beshown by test that complete fus
32、ion is obtained. It is understoodthat a material shall not be tested without also specifying the4Available from American National Standards Institute (ANSI), 25 W. 43rd St.,4th Floor, New York, NY 10036.D 1784 06a2method of specimen preparation. When comparative tests ofmaterials are desired, the gr
33、eatest care shall be taken to ensurethat all specimens are prepared in exactly the same way used tocertify the cell class of the compound. Procedures used inpreparing the test specimens shall be as recommended by thesupplier for each specific compound.NOTE 5It is possible that a specimen taken from
34、a finished productwill not produce the same results as a specimen prepared by the methodused for purposes of cell class testing and certification.11.
