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

15、se groups aresubdivided into classes and grades,as shown in Basic PropertyTable PPE.NOTE4An example of this classification system is as follows:The specification ASTM D4349 PPE 0223 would indicate:PPE=polyphenylene ether,02=polystyrene-modified material(Group),2=flame retarded(Class Description),and
16、3=requirements given in Table PPE.4.1.1 Reinforced,filled,and lubricated versions of PPEmaterials are classified according to the reinforcement used andthe nominal level,by weight percent,of the reinforcement.Thegrade is identified by a single letter that indicates the filler orreinforcement used and two digits that indicate the nominalquantity in percent by weight.Thus,a grade containing 15%glass reinforcement would be indicated by PPE0110 G15.Thiscallout indicates:PPE=polyphenylene ether _ as
