A number of techniques have in the past been proposed for the determination of the life of a plastic pipe exposed to pressure. This paper examines the yield criteria which may be applicable to such a system and proposes a new technique for the interpretation of the accelerated creep rupture curves which may be obtained at elevated temperatures. This new technique is shown to lead to a modified Larson-Miller formulation which fits available data accurately.
