We might have just the form your looking for in the back of our manuals. If this doesn't fit exactly, it might give you a good place to start.

As for a form for the operator to complete listing the size of pipe, SDR rating, recommended fusion pressure and temperature, actual fusion pressure and temperature, etc. I would recommend using a product like the DataLogger. I believe this would give the operator a convenient way to record the information (some automatically) and an excellent QA reporting/recording device. It come with a Windows companion program for storing and managing the downloadable data. You also can use the portable printer in the field for printing out the data along with a "strip chart" type record of the joint. You can find out more information on the DataLogger at:
