LAMPING PROCEDURE
Do the following (refer to Figure 2-3 on page 11 as needed):
1. Check the integrity of the o-rings on the seal plates. Replace any damaged
o-rings.
NOTICE
Any imperfections to the o-ring surface may cause a loss of pressure
during testing.
2. Review Table 3-2 on page 19 for the correct clamping pressure.
3. Place the test valve on the table and align the valve with the correct o-ring
diameter.
WARNING
The relief port of the safety relief valve (that is, the device under test)
should face away from the operator and any other personnel during the
test. The splash shield is not rated for high-pressure impact.
4. For a flanged valve, slide the clamp arms in until they securely engage with
the flange.
5. Check that the clamp pressure control regulator is turned counter-clock-
wise until it stops.
6. On the clamp fixture console, lock the clamp release valve.
7. Open the air supply valve.
8. Turn the clamp pressure regulator clockwise while monitoring the clamp
pressure gauge until the correct pressure is achieved, as listed in Table 3-2
on page 19.
WARNING
The safety interlock is only a secondary measure to the correct
operating procedure. Some residual pressure (up to 20 psi [1.38 bar])
may remain in the valve under test when the safety interlock cylinders
disengage, which may cause a pressure release and personnel injury if
the clamp drain valve is opened. Always remove test pressure, drain
the test circuit, and check that the TEST PRESSURE GAUGE and
VESSEL PRESSURE GAUGE read 0 psi/bar before opening the clamp
drain valve.
