ISO

ISO/TC 197

International Standard

Scope

This document outlines the specification of 60° female cone end-connections for high-pressure
components in hydrogen supply systems. This is appliable for tube couplings up to 12.7 mm
external diameter.

This requirement includes dimensional specification and related tolerances, assembly
description, usage and assembling recommendation, material choices including hardness and
hydrogen compatibility, and related norms.
