Scope

Scope: This document specifies the general requirements, inspection procedures, defect assessment, and record-keeping and reporting for the industrial computed tomography (CT) inspection of aluminum-lined carbon fiber fully wrapped gas cylinders used for compressed hydrogen storage in vehicles. This document applies to hydrogen gas cylinders with a nominal water capacity of no more than 450L, a storage medium of compressed hydrogen, and fixed on road vehicles for use as fuel tanks. It covers defects such as fiber layering and inclusions in the hydrogen gas cylinders. Main technical content: This document was drafted in accordance with GB/T 1.1-2020, "Guidelines for Standardization Work - Part 1: Structure and Drafting Rules for Standardization Documents". It combines the requirements of standards such as GB/T 1260.4.12, GB 18871, GB/T 29034, GB/T 29067, GB/T 29069, GB/T 29070, GB/T 35544, GB/T 37166, GB/T 38535, and GBZ 117. Based on extensive industrial CT inspections and tests of hydrogen gas cylinders, it provides general requirements, inspection procedures, defect assessment, and record-keeping and reporting for hydrogen gas cylinders that comply with GB/T 35544 or other similar standards using industrial CT inspection methods.
