All,

 

I understand that compressed gas cylinders must have a current hydrostatic test to be filled.  I have read a vendor site that indicates that a cylinder may be transported after the hydrostatic test expiration date if it was filled prior to the expiration date.  If cylinders that have exceeded the hydrostatic test date are considered safe to transport are they considered safe to continue using?  In other words, if a compressed gas cylinder is not empty but has exceeded the hydrostatic test expiration date is it required by regulation or prudent practice to be returned for testing or can it continue to be used? 

 

Thanks,

Ben
