Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification cover
3、s nonrigid vinyl chloride poly-mer and copolymer classes in which the resin portion of thecomposition contains at least 90 % vinyl chloride. The remain-ing 10 % can include one or more monomers copolymerizedwith vinyl chloride or consist of other resins mechanicallyblended with polyvinyl chloride or
4、 copolymers thereof.1.2 These nonrigid vinyl compounds are defined by ahardness range and include the necessary stabilizers, plasticiz-ers, fillers, dyes, and pigments to meet the designated require-ments.1.3 This specification includes nonrigid vinyl chloride com-pounds recommended for compression
5、molding, injectionmolding, and extrusion, but it must be recognized that particu-lar compounds are not suitable for all these means of fabrica-tion.NOTE 1This standard and ISO 2898-1 and ISO 2898-2 address thesame subject matter, but differ in technical content.1.4 The values stated in SI units are
6、to be regarded as thestandard. The values given in parentheses are for informationonly.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices
7、and determine the applica-bility of regulatory limitations prior to use.1.6 The text of this specification references notes andfootnotes which provide explanatory material. These notes andfootnotes (excluding those in tables and figures) shall not beconsidered as requirements of this specification.1

16、en, PA 19428-2959, United States.4. Classification4.1 Provision is made in this specification for the identifi-cation of vinyl chloride polymers and copolymers by use ofTerminology D1600. Additionally, there is provision for dis-tinguishing electrical grades and burning rate by suffix. Thesystem of
17、classification provided in Table 1 permits character-ization and identification of all compounds having propertieswithin the ranges of the combinations that may be selectedfrom the table. Following type identification in accordancewith Terminology D1600, grades are designated by the cellnumber for e
18、ach property in the order in which they are listedin Table 1, including the suffixes identifying electrical gradesand flammability when required. 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 se
19、lected materials are identified isillustrated by the examples given below:NOTE 3The cell-type format provides means for close characteriza-tion and specification of material properties, alone or in combination, fora broad range of materials. This format, however, is subject to possiblemisapplication
20、 since unobtainable property combinations can be selectedif the user is not familiar with commercially available materials. Themanufacturer 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 Th
21、e designated material shall contain the ingredientsnecessary to permit satisfactory processing with appropriateequipment under recommended or commercially acceptableconditions. There shall be no separation of components underconditions of application normal for these compounds.TABLE 1 Detail Grade R

The propertiesenumerated in this table and the tests defined are expected toprovide identification of the compoun
25、ds 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 comparative data be expected. The testsselected can also be used for inspe
26、ction 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 limits of variability of the material being examinedand of the tests used for
