Step 1:Charge for more than 3 minutes under 0.3MPa(3.0kg/cm
Step 2:Charge for more than 3 minutes under 1.5MPa(15kg/cm
--Serious leakage may be found.
Step 3:Charge for more than 24 hours under 3.0MPa(30kg/cm
--Small leakage may be found.
Check for pressure decrease
Without pressure decrease-Pass
With pressure decrease-Check for leakge.
There will be a 0.01MPa(0.1kg/cm
the 24-hour pressure charge.It should be corrected during the test.
