[MW:7198] effect of longer holding time during hydrotest

Dear All
 
Goodday.
 
 
On what basis holding duration (eg.1 hour, 2hour etc) of hydrotest is decided.
 
 
What will be the effect on mechanical proerty of material if the holding period exceeds than as required by design.
 
eg. suppose for a particular hydrotest  holding period is 2 hours and actual holding period exceeds to 3 hours. what will be the effect on mechanical proerty.
 
 
Thanks in advance for your valuable suggestions.
 
Best Regards
 
Asad Azmi
