Joe,
Does Bob have any technical data that says the cold flow effect will produce less than a 15% torque change?

Don: no technical data, on this job the electrical engineers, contractor and myself agreed to the 15% as the torque inspection would be done about 1 hour after the installation. The system was new never energized, the torque was on bolted lugs with copper conductors, and the temperature in the area was contolled.
No one felt cold flow, thread lubricants, or differences in wreaches as something that would effect the installation or my inspection settings.
After inspecting 1100 plus terminations everyont felt the process was OK.
