there is no set time for strength test I test for up to 30 mins then leak test for 24 hrs

cheers martin, I have been strength testing for about an hour,so not to much difference. can a leak test and strength test be done at the same time for example, if you have a system with no joints and you test with leak spray whilst doing a strenght test?

thay need to be seperate as ofn has larger molicules than 410a so takes longer to leak
