ISO 10931-5:1998 pdf free download.Plastics piping systems for industrial applications — PoIy(vinylidene fluoride) (PVDF) — Part 5: Fitness for purpose of the system.
This part of ISO 10931 specifies the requirements for the fitness for purpose of piping systems made from poly(vinylidene fluoride) (PVDF) for industrial applications, i.e. the conveyance of water and chemicals in the liquid or gaseous state. It also specifies the test parameters for the test methods referred to in this part of ISO 10931.
It is applicable to PVDF assemblies for the conveyance of fluids under pressure at temperatures up to 150 CC. However, applications above 120 CC, which depend on the crystalline melting point of the PVDF material1 need to verified with the suppliers of the components.
NOTE — For information on the resistance of PVDF materials in contact with chemicals, see ISO/TR 10358:1993, Plastics pipes and fittings — Combined chemical-resistance classification table.
