5.1.1 Pop-off pressure safety relief valve test. This test shall verify conformance to 3.3.7.1 and shall be performed on each spray gun offered for acceptance. An air pressure gage capable of measuring pressure in the gun cup shall be installed. The gage shall be accurate within one percent over the range of 45 to 65 psig and readable to the nearest psig. Starting with the air regulator adjusted to 40 psig, adjust the regulator slowly upward, carefully observing the gage air pressure, until the pop-off pressure safety relief valve opens. The pressure release point shall be not less than 50 psig and not more than 60 psig. The valve shall reset itself upon reduction of pressure below the release point. Failure of the relief valve to open in the range of 50 to 60 psig, or failure of the valve to reset itself shall be cause for rejection.
