PTI Test Procedures

General Considerations:

1. Every liner shipped from PTI receives the standard electrical test of exposure to 50,000 volts, AC-RMS, before shipment. Liners are unconditionally guaranteed to withstand a similar test for 2 (two) years with the only exception being physical abuse caused by the user. (We can't help the situation where a lineman steps in with spikes.) Under our guarantee, we replace the liner - full details can be found on the Guarantee certificate.

2. PTI also supplies liners tested to 70,000 volts for one minute. Extra voltage testing requires advance ordering since the liners are slightly heavier. Special manufacturing considerations are also utilized to ensure uniform testing. The 70,000 volts tested liners are covered by PTI's standard Guarantee.

3. Liners should be subjected to a dialectic acceptance test by the utility to guard against any damage in transit. Re-testing by utilities is done on widely varying arrangements. We are familiar with companies who re-test every month as well as organizations who do it every two years. What is best, is up to the individual safety department.

4. All PTI testing is done with AC. To compare an AC test with a DC test, the DC voltage would have to be approximately 2.5 to 3 times the AC voltage. It should also be noted that PTI measures voltage as RMS. This is equal to approximately 100,000 volts, AC, peak-to-peak.

5. Additional general information on the liners and polyethylene material is printed on the reverse side of our basket liner data sheets shipped with each liner.
