7. Reduce the air pressure to 4.0 inches of water column (or according to the test kit
instructions) by disconnecting the air supply and slowly opening the valve. Close the valve
when the pressure reaches 4.0 inches water column and immediately start the timer.
8. After four (4) minutes, read the air pressure gauge. If the pressure has not dropped below
3.2 inches water column, the garment has passed.
Note: A pressure reading of 3.2 inches of water column is equivalent to a 20% drop in
pressure allowed by the ASTM standard)
9. If the pressure falls below 3.2 inches water column before the end of the four (4) minutes,
the garment should be removed from service and checked for leaks. Air leaks often occur
at the glove interfaces, at the zipper closure point and around exhaust valves. Inflate the
garment to 5.0 inches water column and spray a soapy water solution at various points
over the garment to locate leaks. For additional information, contact Kappler.
10. After completion of the pressure test, remove the test kit adapters by twisting and
unlocking from valves. Immediately replace diaphragms.
