ISO 10931-5:1998 pdf download – Plastics piping systems for industrialapplications – Poly(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(vinyfidene 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 ISO C. However. applications above 120 C. which depend on the crystalline melting point of the PVDF matenal, need to verified with the suppliers of the components
NOTE — For information on the resistance of PVDF materials in contact with diemicals. see ISG’TR 10356:1993, PYastics pipes and fittings — Cornblned chemical-resistance ctassifacation table
