ISO 21787:2006 PDF

Scope: This International Standard specifies requirements for the design, functional characteristics and manufacture of globe valves made of thermoplastics materials intended for isolating and control 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 DN DN 10; DN 15, DN 20, DN 25, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125 and DN 150 and the range of PN and Class PN 6, PN 10, PN 16 and Class 150.
