1.If, because of sample size, this test cannot be completed on the liner, then conduct testing on a molded

plaque sample. Samples can be removed if test time exceeds 100 hours without failure.

2.OIT and MI tests on the crown are required when resin used in the corrugation is different than that of the

liner.

3.The incubation duration and temperature can also be 192 days at 194F or 140 days at 203F.

4.Perform the tests for incubated and "as -manufactured" pipe samples by the same lab, same operator, the

same testing device, and in the same day.

5.Within each replicate set of tests, the discrepancy range is to be within 9%. If an out -of-range discrepancy

occurs, repeat the two MI tests on the same pipe sample. If insufficient material is available, a repeat of one test is acceptable.

6.The MI retained value is determined using the average MI value of incubated sample divided by the

average MI value of as -manufactured pipe sample.
