18、A (normative). 1 Scope 1.1 This part of IS0 2898 establishes a system of designation for plasticized thermoplastic material which may be used as the basis for specifications. 1.2 The types of PVC-P plastics are differentiated from each other by a classification system based on appropriate levels of
19、the designatory properties a) Shore hardness b) density c) and on information about physical form, intended application and/or method of processing, important properties, additives and colorants. torsional-stiffness temperature at 300 MPa 1.3 This part of IS0 2898 is applicable to all plasticized co
20、mpositions of homopolymers and copolymers that con- tain at least 50 % (dm) of vinyl chloride. It is also applicable to plasticized compositions containing chlorinated poly(viny1 chloride) and to plasticized compositions containing blends of one or more of the above-mentioned poly- mers, provided th
21、at the total amount of these polymers represents at least 50 % (nh) of the polymer content of the comoosition. This part of IS0 2898 applies to materials ready for normal use in the form of powder (dry blends), granules or pel- lets, unmodified or modified by colorants, additives, fillers, etc. This
22、 part of IS0 2898 does not apply to cellular plastics or to paste compositions (plastisols). 1.4 It is not intended to imply that materials having the same designation give necessarily the same performance. This part of IS0 2898 does not provide engineering data, performance data or data on processi
23、ng conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified in part 2 of this International Standard, if suitable. 1.5 In order t
24、o specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see clause 3, first paragraph).
