Gas cylinders - Composite construction - Periodic inspection and testing
ISO 11623:2015 specifies the requirements for periodic inspection and testing and to verify the integrity for further service of hoop-wrapped and fully-wrapped composite transportable gas cylinders, with aluminium-alloy, steel or non-metallic liners or of linerless construction (Types 2, 3, 4, and 5), intended for compressed, liquefied or dissolved gases under pressure, of water capacity from 0,5 l up to 450 l.ISO 11623:2015 is written to address the periodic inspection and testing of composite cylinders constructed to ISO 11119‑1, ISO 11119‑2, and ISO 11119‑3 standards and can be applied to other composite cylinders designed to comparable standards when authorized by the competent authority.As far as practicable, this International Standard also can be applied to cylinders of less than 0,5 l water capacity.

Le présent document prescrit les contrôles et essais périodiques à effectuer sur les bouteilles à gaz en matériau composite, quelles soient entièrement bobinées ou frettées, dotées d'un liner métallique ou non métallique ou sans liner. Il complète ainsi les normes NF EN 12245 (indice de classement : E 29-751) et NF EN 12257 (indice de classement : E 29-752) sur la construction des bouteilles bobinées et frettées.
This document specifies the requirements for periodic inspection and testing to verify the integrity for further service of hoop-wrapped and fully-wrapped composite transportable gas cylinders and tubes, with aluminium-alloy, steel or non-metallic liners or of linerless construction (Types 2, 3, 4, and 5), intended for compressed, liquefied or dissolved gases under pressure, of water capacity from 0,5 l up to 3 000 l. This document addresses the periodic inspection and testing of composite cylinders and tubes constructed according to ISO 11119-1, ISO 11119-2, ISO 11119-3, ISO 11119-4 or ISO 11515. It can be applied to other composite cylinders and tubes designed to comparable standards when authorized by the competent authority. As far as practicable, this document can also be applied to cylinders of less than 0,5 l water capacity when authorized by the manufacturer. NOTE Unless noted by exception, the use of the word “cylinder” in this document refers to both cylinders and tubes.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
With Requirements, quickly access the main part of the normative text!

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.
