How much time should be allowed before a 6-inch diameter CPVC piping system installed at 85°F (29°C) be hydrostatically pressure tested?
The appropriate cure time for the stated application is a minimum of 24 hours after the last joint of the piping system is assembled before the system can be hydrostatically pressure tested. Please refer to the set and cure time charts for our Weld-On products. Set Time is the time required before the joint can be carefully handled. Cure Time is the time required before the piping system can be hydrostatically pressure tested at a maximum of 150% of the system design pressure. DANGER: Air or compressed gas must NEVER be used for system acceptance testing. Use HYDROSTATIC (water) PRESSURE TEST ONLY. System failure, when using compressed air or gas for system acceptance testing, can result in bodily injury, death, and/or property damage.
