Interpretation of Fatigue Data Surfaces to Optimise Product Evaluation Test Levels

The use of fatigue loading as a test medium for the quality assurance of commercial gas and water pipe components is postulated. The establishment of an appropriate system requires that the many test variables are optimised into a realistic test procedure. A computer‐aided design package was used to reduce this optimising process. The technique described may be used on any multi‐faceted program of similar type.
