适用范围: This document establishes a system of designation for poly(phenylene sulfide) (PPS) thermoplastic materials@ which can be used as the basis for specifications. The types of poly(phenylene sulfide) (PPS) materials are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) melt mass-flow rate or melt viscosity; b) density; c) tensile modulus; and on information about the intended application and/or method of processing@ important properties@ additives@ colorants@ fillers and reinforcing materials. This document is applicable to all PPS materials. It applies to materials ready for normal use in the form of powder@ granules or pellets and to materials unmodified or modified by colorants@ additives@ fillers@ etc. It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data@ performance data or data on processing conditions which can be required to specify a material for a particular application and/or method of processing. If such additional properties are required@ they are intended to be determined in accordance with the test methods specified in ISO 20558?2@ if suitable. In order to specify a thermoplastic material for a particular application or to ensure reproducible processing@ the requirements are given in data block 5 (see 4.1).
