Ststutatory requirements depend upon mfrs. recommendation, clients requirement, or continuously used more than 4 times or while testing if there is any more difference than tolerance or calibrated test certificate reading or not working properly during test or any damage or more heat zone then you have to recalibrate and compare reading . if it goes beyond tolerance or acceptable limit of std engineering procedure simply throw it and replace with new calibrated by accredited body such as NABL approved labs.

>Dear Karthik :
I have a complicated situation with pressure gauge calibration period.
During calibration test, our gauge found to be showing wrong reading (below actual). And clients ask to re-test all spool pipe tested using the gauge.
My question, is that acceptable ? luckily there are only small number of spool to be re-tested, but I cant imagine if that happens to spools that already put in service.re
Just a share, but I appreciate any coments and advise.
Best Regards
Bonardo
