Over deze norm
Specifies the characteristics of valves 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 valves for the conveyance of fluids under pressure at temperature up to 150Â°C. However applications above 120Â°C, which depend on the crystalline melting point of the PVDF material, need to be verified with the valve supplier.
