and valves for the transport of fluids”, which is a Technical Committee of the International Organization for
Standardization (ISO).
They are supported by separate standards on test methods to which references are made throughout the
System Standard.
The System Standards are consistent with general standards on functional requirements and on recommended
practice for installation.
