Gaseous hydrogen — Pressure vessels for stationary storage — Part 3: Pressure cycle test data to demonstrate partial pressure cycle estimation methods

Апстракт

This document describes detailed methods for evaluating cycle life extension by partial pressure cycles with necessary conditions and example data of their application.
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.
