Pressure Tests
TEST LOCATION
Pressure tests shall be performed by the valve manufacturer
at the valve manufacturer’s plant.
TEST EQUIPMENT
The equipment used by the valve manufacturer to perform
the required pressure tests shall not apply external forces that
affect seat leakage. If an end-clamping fixture is used, the
valve manufacturer shall be able to demonstrate that the test
fixture does not affect the seat sealing capability of the valve
being tested. End clamping is allowed for valves designed to
function between mating flanges, such as wafer check and
wafer butterfly valves.
TESTS REQUIRED
The pressure tests shall be
performed on each valve in accordance with written procedures
that comply with this standard.
At the manufacturer’s option, the backseat test for
valves that have the backseat feature may be either a high pressure
or a low-pressure test unless stated otherwise in the
purchase order.
Valves NPS 4 and smaller having pressure ratings up
to and including ASME Class 1500 and valves larger than
NPS 4 having pressure ratings up to and including ASME
Class 600 shall be tested in accordance with Table 1-A.
