Bibliography

Defines requirements for the type testing of isolating valves for low-temperature applications to verify the performance of valves at a low temperature from -50 degrees C down to -196 degrees C.

This part of ISO28921 specifies requirements for the type testing of isolating valves for low-temperature applications to verify the performance of valves at a low temperature from – 50°C down to – 196°C. WARNING— Nominal sizes (DN), nominal pipe sizes (NPS), nominal pressure (PN) and Classes are covered in ISO28921‑1 . This part of ISO28921 does not evaluate valve actuators unless they are integral part of the valve. Valves during testing can be operated manually or an actuator can be used during the testing. The effect of cold gas vapours during testing is taken into consideration in particular if the actuator is mounted directly over the test stand with the cold gases engulfing the actuator. This part of ISO28921 does not apply to valves for cryogenic services, designed in accordance with ISO21011 , used with cryogenic vessels.
