标准范围

This International Standard specifies requirements for the design, functional characteristics and manufacture of gate valves made of thermoplastics materials intended for isolating service, their connection to the pipe system, the body materials and their pressure/temperature rating between - 40 °C and + 120 °C, for a lifetime of 25 years, and also specifies their tests.This International Standard is applicable to hand- or power-operated valves to be installed in industrial pipe systems, irrespective of the field of application and the fluids to be conveyed.NOTE 1 Industrial pipe systems also include systems for water supply for general purposes, drainage and sewerage.NOTE 2 Special requirements can apply to pipe systems for water for human consumption.This International Standard is concerned with the range of DNDN 10, DN 15, DN 20, DN 25, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300 and DN 350.and the range of PN and ClassPN 6, PN 10, PN 16, and Class 150.
