1.1 This classification system covers the basic polymers and copolymers known as polyphenylene ethers and polyphenylene oxides, as well as filled, modified, and reinforced versions. Note 1Addition to the natural polymer or copolymer of pigments, colorants or additives may result in the final composition not meeting the requirements specified for the natural polymer or copolymer. Discussions with the supplier should take place before specifications of altered compositions are established.
Note 2The preferred abbreviation for polyphenylene ether is PPE, as noted in Terminology D 1600.
1.2 This classification system is not intended for the selection of materials, but only as a means to call out plastic materials to be used for the manufacture of parts. The selection of these materials is to be made by personnel with expertise in the plastics field where the environment, inherent properties of the materials, performance of the parts, part design, manufacturing process, and economics are considered.
1.3 There may be other requirements necessary to identify particular characteristics important to specific applications. These may be specified by using the suffixes described in Section .
1.4 The values stated in SI units are to be regarded as the standard. Note 3No ISO standard exists that covers these materials.
