BS EN ISO 20568-1-2015 pdf download.Plastics一Fluoropolymer dispersion and moulding and extrusion materia ls一 Part 1: Designation system and basis for specifications.
1.3 The designation system is applicable to all fluoropolymers and blends. It applies to unmodified materials ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing materials, and polymer modifiers
1.4 One should not assume that materials having the same designation give the same performance. This part of ISO 20568 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material. If such additional properties are required, they shall be determined in accordance with the test methods specified in part 2 of this International Standard. if suitable.
1.5 In order to designate a thermoplastic material to meet particle specifications, the requirements are to be given in data block 5 (see 3.1).
