Abstract

Two methods for evaluating cycle life extension by partial pressure cycles based on the Goodman diagram and exponential formula are presented in ISO 19884-1. These methods do not rely on fracture mechanical methodology but on pressurizing cycle test data, since the framework of ISO 19884-1 is constructed on performance demonstrated by pressurizing cycle test data in hydrogen. This document describes detailed methods with necessary conditions with example data of their application.
