The high-temperature teat is usually scheduled early in the test sequence following initial dynamic transportation tests. This test may contribute significantly to the results of low pressure testing of seals. Test v=iathns. This method provides a choice of two subtests: Prooe%res I (Storage) and II (Operation).
