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,plasticizers, fillers, dyes, and pigments to meet the designatedrequirements.1.3 This specification includes nonrigid vinyl chloride com-pounds recommended for compression mold
5、ing, 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 to b

Terminology3.1 GeneralDefinitions are in accordance with Terminol-ogy D883 and abbreviations with Terminology D1600, unle
16、ssotherwise indicated.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 classificat
17、ion 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 each propert
18、y 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 selected mate
19、rials 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 since unob
20、tainable 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 The designate
21、d 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.6. Significance and Use6.1 Means
