IPS WELD-ON SOLVENT CEMENTS MUST NEVER BE USED IN SYSTEMS USING OR BEING TESTED BY COMPRESSED AIR OR GASES.

AVERAGE INITIAL SET TIMES FOR WELD-ON PVC/CPVC SOLVENT CEMENTS*

Temperature Range	Pipe Sizes ¹/2" to 1¹/4"	Pipe Sizes 1¹/2" to 2"	Pipe Sizes 2¹/2" to 8"	Pipe Sizes 10" to 15"	Pipe Sizes 15"+
60°-100°F	2 min	5 min	30 min	2 hrs	4 hrs
40°-60°F	5 min	10 min	2 hrs	8 hrs	16 hrs
0°-40°F	10 min	15 min	12 hrs	24 hrs	48 hrs

* In damp or humid weather allow 50% more set time; extended set times are required for chemical applications.

Note - Initial set time is the necessary time needed before the joint can be carefully handled.

AVERAGE JOINT CURE SCHEDULE FOR WELD-ON PVC/CPVC SOLVENT CEMENTS*

Relative Humidity 60% or Less	Cure Time Pipe Sizes ¹/2" to 1¹/4"		Cure Time Pipe Sizes 1¹/2" to 2"		Cure Time Pipe Sizes 2¹/2" to 8"		Cure Time Pipe Sizes 10" to 15"	Cure Time Pipe Sizes 15"+
Temperature Range During Assembly and Cure Periods	up to 160 psi	160-370 psi	up to 160 psi	160-315 psi	up to 160 psi	160-315 psi	up to 100 psi	up to 100 psi

0°-40°F	30 min	48 hrs	1 hr	96 hrs	72 hrs	8 days	8 days	14 days

* In damp or humid weather allow 50% more cure time; extended cure times are required for chemical applications.

Note - Joint cure schedule is the necessary time needed before pressurizing system.
