12. Full set time is a minimum of 30 minutes at 60°F to 100°F. Full cure time should be based on
the chart below.
The cure schedules are suggested as guides. They are based on laboratory test data, and should
not be taken to be the recommendations of all cement manufacturers. Individual manufacturer's
recommendations for their particular cement should be followed.

Extreme care should be exercised on all joints made where pipe, fittings or cement is below 10ºF (-15ºC).
A. It is important to note that at temperatures colder than 20ºF on sizes that exceed 3 in., test
results indicate that many variables exist in the actual cure rate of the joint. The data expressed
in these categories represent only estimated averages. In some cases, cure will be achieved in
less time, but isolated test results indicate that even longer periods of cure may be required.
B. These cure schedules are based on laboratory test data obtained on Net Fit Joints (NET FIT=in
a dry fit the pipe bottoms snugly in the fitting socket without meeting interference).
Standard Threaded Connection Practices
Threaded end connections should be manufactured to ASTM specifications D2464-99. F437-99 and
ANSI B2.1.
1. Wrap threads of pipe with Teflon tape of 3 to 3-1/2 mil thickness. The tape should be wrapped
in a clockwise direction starting at the first or second full thread. Overlap each wrap by, 1/2 the
width of the tape. The wrap should be applied with sufficient tension to allow the threads of a
single wrapped area to show through without cutting the tape. The wrap should continue for
the full effective length of the thread. Pipe sizes 2" and greater will not benefit with more than
a second wrap, due to the greater thread depth.
2. To provide a leak proof joint, the pipe should be threaded into the end connection "hand tight".
3. Using a strap wrench only (never use a Stillson type wrench), tighten the joint an additional 1/2
to 1-1/2 turns past hand tight. Tightening beyond this point may induce excessive stress that
could cause failure.
