Sec. 230.45  Method of testing.



    Steam gauges shall be compared with an accurate test gauge or dead 

weight tester. While under test load at the MAWP of the boiler to which 

the gauge will be applied, the gauge shall be set to read that pressure 

as accurately as the physical limitations of the gauge will allow. Under 

test the gauge shall read within the manufacturer's tolerance at all 

points on the gauge up to 25 percent above the allowed pressure. If the 

manufacturer's tolerance is not known, the gauge must read within 2 

percent full scale accuracy at all points on the gauge up to 25 percent 

above allowed pressure.
