C. Test Equipment
Test stands (Figure 10) shall consist of a pressure
source, a supply line with a throttle valve, and a
receiver having the following features:
1. Outlet for attaching valve to be tested.
2. Pressure gauge with a shut-off valve.
3. Drain line with a shut-off valve.
4. A volume in receiver adequate for the valve to
be tested to achieve adequate operation.
D. Cold Differential Set
Pressure
When a Consolidated Safety Relief Valve is to
be set on a test stand at room temperature and
atmospheric back pressure and is to operate at a
higher temperature and/ or a higher back pressure,
a set pressure adjustment is required. The adjusted
set pressure is designated as the “Cold Differential
Set Pressure.”
E. Temperature Adjustment
Safety relief valves set at atmospheric temperatures
and are to be used at higher temperatures
should have the set pressure adjusted as per the
appropriate multiplier listed in Table 5.
