3、 specification covers 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 % may include one or more monomers copolymerizedwith vinyl chloride or consist of other resins mechanicallyblended with p
4、olyvinyl chloride or 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 recommen
5、ded for compression molding, injectionmolding, and extrusion, but it must be recognized that particu-lar compounds may not be suitable for all these means offabrication.NOTE 1This standard is similar in content, but not technicallyequivalent to ISO 2898-1:1986 and ISO 2898-2:1989.1.4 The values stat
6、ed in SI units are 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 an

Classification4.1 Provision is made in this specification for the identifi-cation of vinyl chloride polymers and copolyme
17、rs by use ofTerminology D 1600. 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 combinations that
18、 may be selectedfrom the table. Following type identification in accordancewith Terminology D 1600, 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 required. When a pr
19、operty 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-tion and specifi
20、cation 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 should be consu
21、lted.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 or commercially
22、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 and the tests def
23、ined 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 comparative data
24、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 limits of variability
