DIN EN ISO 20558-1:2018-11

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 propertiesa) 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.
