The standard for fitting of valves to gas cylinders has been updated, the current version is now BS EN ISO 13341:2025 (Gas cylinders. Fitting of valves to gas cylinders). It replaces BS EN ISO 13341:2010+A1:2015 which is now withdrawn.
The main changes are as follows:
• update of Clause 2 and Bibliography
• addition of a requirement in 5.3 with regards to the cleaning of cylinder threads.
All centres undertaking PI or PIAT of composite cylinders should take steps to update their standards library to the current version.
