1、Designation:D434910Classification System and Basis for Specification forPolyphenylene Ether(PPE)Materials1This standard is issued under the fixed designation D4349;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revi
2、sion.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This classification system covers the basic polymers andcopolymers known as polyphenylene ethers and polyphenyleneoxides,as well as
3、 filled,modified,and reinforced versions.Recycled materials are included in this standard as Class 5 ofTable PPE.NOTE1Addition to the natural polymer or copolymer of pigments,colorants,or other additives can cause the final composition to no longermeet the requirements specified for the natural poly
4、mer or copolymer.NOTE2The preferred abbreviation for polyphenylene ether is PPE,asnoted in Terminology D1600.1.2 This classification system and subsequent line callout(specification)are intended to provide a means of calling outplastic materials used in the fabrication of end items or parts.It is no
5、t intended for the selection of materials.Materialselection should be made by those having expertise in theplastic field after careful consideration of the design and theperformance required of the part,the environment to which itwill be exposed,the fabrication process to be employed,thecosts involv
