The standard for periodic inspection and testing of composite cylinders has been updated, the current version is now BS EN ISO 11623:2023 (Gas
cylinders. Composite cylinders and tubes. Periodic inspection and testing). The previous 2015 version is ‘withdrawn’.
The main changes are as follows:
- revision of the Scope to include cylinders and tubes with a water capacity up to 3,000 litres;
- modification of Table 1 to separate abrasion damage based on water capacity of the cylinder;
- clarification that a transparent sleeve may be left in place during inspection (7.1.3);
- clarification on the use of tare during inspection.
All centres undertaking PI or PIAT of composite cylinders should take steps to update their standards library to the current version.
