What is ISO 16135- Ball valves of thermoplastic materials about?
ISO 16135 specifies requirements for the design, functional characteristics, and manufacturing of ball valves made of thermoplastics materials intended for isolating service, for control service, and to divert/mix fluids, 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, nd specifies their tests.
ISO 16135 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.
