VAPOR INTEGRITY TEST
0168 00
NOTE
Select an area with minimum temperature changes,
which directly affect pressure readings. Do not perform
the pressure test in direct sunlight.
Visually inspect outside of tank and all associated piping.
Look for stained areas that indicate obvious leakage.
Repair obvious leaks prior to performing pressure test.
Inspect discharge valve to ensure leak-free operation.
Make sure test equipment gages are set to zero by turning
adjusting screw on each gage.
Perform EPA (Environmental Protection Agency) Method 27
for the leak test; this procedure tests tankers to MC306 or
DOT406 standards.
