A record should be kept of the readings taken from the time the cable is first installed on the pipe. A history of the insulation resistance
reading can be helpful in spotting moisture ingress into the electrical system (by seeing a gradual decline in the insulation resistance or
physical damage to the heating cable (sharp decline in the insulation resistance). A sample record for this is shown in Figure 20. (See
following page)

Remarks & Comments
Periodic Inspection Record Form
The Periodic Inspection record Form may be used in one of two ways:
1. One sheet per circuit - The results of periodic tests of a single circuit are posted in vertical columns, beginning on the left and
working toward the right. This allows easy comparison of test values for up to seven test sequences on an individual circuit.
2. One circuit per column - Test data for a single test sequence on as many as seven circuits can be recorded on a single sheet.
