DIN EN ISO 28941-1-2009 塑料 聚苯醚(PPE)模制和挤压成型材料 第1部分:命名体系和规范基础
Plastics - Poly(phenylene ether) (PPE) moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 28941-1:2008); English version of DIN EN ISO 28941-1:2009-04
1.1 This part of ISO 28941 establishes a system of designation for PPE thermoplastic materials, which may
be used as the basis for specifications.
1.2 The types of PPE plastic are differentiated from each other by a classification system based on
appropriate levels of the designatory properties
a) temperature of deflection under load
b) melt volume-flow rate
c) Charpy notched impact strength
d) flammability
and on information about basic polymer parameters, intended application and/or method of processing,
important properties, additives, colorants, fillers and reinforcing materials.
1.3 This part of ISO 28941 is applicable to all PPE materials, including those modified with polystyrene or
polyamide or other 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.
1.4 It is not intended to imply that materials having the same designation necessarily have the same
performance. This part of ISO 28941 does not provide engineering data, performance data or data on
processing 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 ISO 15103-2, if suitable.
1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible
processing, additional requirements may be given in data block 5 (see 3.1).
