ASME BPVC 2023 Section I

A-22.11 Test Gages.
A-22.11.1 An indicating gage shall be connected
directly to the pressure parts. If the indicating gage is
not readily visible to the operator controlling the pressure
applied, an additional indicating gage shall be provided
where it will be visible to the operator throughout the
duration of the test. For large pressure parts, it is recommended
that a recording gage be used in addition to indicating
gages.
A-22.11.2 Pressure gages used in testing shall
comply with PG-99.4.
A-22.11.3 All gages used in proof testing shall be
calibrated against a standard deadweight tester or a calibrated
master gage before the proof test is begun. Gages
shall be recalibrated at any time that there is reason to
believe they are in error.

PRESSURE RELIEF VALVES FOR POWER
BOILERS
ð23 A-44
The minimum pressure relief valve relieving capacity
for other than electric boilers, waste heat boilers,
organic fluid vaporizers, and forced-flow steam generators
with no fixed steam and waterline, when provided
in accordance with PG-67.4.3, may be estimated on the
basis of the pound mass of steam generated per hour
per square foot kilogram per hour per square meter
of boiler heating surface and waterwall heating
surface, as given in Table A-44.
In many cases, a greater relieving capacity of pressure
relief valves will have to be provided than that estimated
using Table A-44, in order to meet the requirements of the
first paragraph of PG-67.2.
