What is BS 6564-3 – Specification for E glass fibre filled PTFE about ?
BS 6564 is a British Standard that discusses polytetrafluoroethylene (PTFE) materials and products. The main aim of the BS 6564 series is to provide best industry guidance on the manufacture of PTFE materials and products such that they are fit for its intended use. BS 6564-3 is the third part of the BS 6564 series that provides the composition and physical property requirements for E glass fibre filled PTFE fabricated products. The style of the designation follows closely the designation introduced into BS 6564-2 for unfilled products. In BS 6564-3 , the requirements are specified in three grades of product which are designated grade G5, G15 and G25 containing a nominal 5 %, 15 % and 25 % of E glass fibre filler. BS 6564-3 specifies requirements for fabricated E glass fibre filled polytetrafluoroethylene (PTFE) products which may occur in several forms, available in the grades, subgrades and types as indicated in Table 1 of the standard. Note: BS 6564-3 does not include any detailed information on machining tolerances but it should be noted that some difficulty in achieving closely controlled dimensions may be experienced when working with PTFE.
