16、 Test Specimens and Determina-tion of Properties3. Terminology3.1 GeneralDefinitions are in accordance with Terminol-ogy D883 and abbreviations with Terminology D1600, unlessotherwise indicated.4. Classification4.1 Provision is made in this specification for the identifi-cation of vinyl chloride pol

17、ymers and copolymers by use ofTerminology D1600. Additionally, there is provision for dis-tinguishing electrical grades and burning rate by suffix. Thesystem of classification provided in Table 1 permits character-ization and identification of all compounds having propertieswithin the ranges of the

18、combinations that may be selectedfrom the table. Following type identification in accordancewith Terminology D1600, grades are designated by the cellnumber for each property in the order in which they are listedin Table 1, including the suffixes identifying electrical gradesand flammability when req

19、uired. When a property is notspecified, a “0” is entered as the cell number unless identifi-cation is terminated prior to that point.NOTE 2The manner in which selected materials are identified isillustrated by the examples given below:NOTE 3The cell-type format provides means for close characteriza-

20、tion and specification of material properties, alone or in combination, fora broad range of materials. This format, however, is subject to possiblemisapplication since unobtainable property combinations can be selectedif the user is not familiar with commercially available materials. Themanufacturer

21、 should be consulted.5. General Requirements5.1 Material shall be of uniform composition and be socompounded as to meet the requirements designated for it.5.2 The designated material shall contain the ingredientsnecessary to permit satisfactory processing with appropriateequipment under recommended

22、or commercially acceptableconditions. There shall be no separation of components underconditions of application normal for these compounds.6. Significance and Use6.1 Means for selecting and identifying nonrigid vinylchloride compounds are provided in Table 1. The propertiesenumerated in this table a

23、nd 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. Only when specimens are molded in accor-dance with 11.1.1 can c

24、omparative data be expected. The testsselected may be employed for inspection or quality controlprovided that they are performed strictly in accordance with theinstructions given herein and in the designated methods so thatextraneous variables are minimized and results are reproducedwithin the limit

25、s of variability of the material being examinedand of the tests used for its examination.7. Detail Requirements7.1 Compliance with the designated requirements shall bedetermined with test specimens prepared of sheets molded inaccordance with 11.1.1 of this specification.7.2 Test values for specimens
