Overview
EN ISO 9539:2010 (ISO 9539:2010) specifies material requirements for gas welding equipment used in gas welding, cutting and allied processes. It covers general and some special requirements for metallic and non‑metallic materials used in components that contact process gases. The standard helps manufacturers, designers and safety engineers select materials that ensure chemical, mechanical and thermal compatibility across typical operating conditions.
Keywords: ISO 9539, gas welding equipment materials, materials for gas welding, oxygen compatibility, acetylene safety
