Overview - EN ISO 13088:2012 (Gas cylinders - Acetylene cylinder bundles)

EN ISO 13088:2012 (identical to ISO 13088:2011) specifies the minimum requirements for filling conditions and filling inspection of acetylene cylinder bundles. It covers bundles filled while cylinders are assembled as a unit and bundles made from individually filled cylinders that are later assembled. It excludes bundles containing solvent-free acetylene cylinders and individual acetylene cylinders not intended for bundling (see ISO 11372).

Key topics and technical requirements

• Scope and definitions: clear terminology for acetylene cylinder, bundle, porous material, solvent, saturation gas, tare, maximum acetylene content and working pressure.
• Filling conditions: general rules for safe filling, accounting for solvent content and maximum acetylene charge; reference to cylinder types in ISO 3807 or equivalent.
• Assembly, marking & documentation: requirements for permanent manifold assembly, frame components, marking verification and record-keeping before and after filling.
• Filling inspection: structured inspection stages including pre-fill inspection, inspection during filling, and post-fill inspection to verify solvent levels, residual gas and compliance with tare/gross weight limits.
• Solvent control: procedures and limits for solvent content in bundles, including the concept of a solvent operating range (Annex A) and methods to determine solvent content during inspection (Annex B).
• Operational limits: definitions for maximum acetylene content, maximum acetylene charge, and related tare/gross weights for bundle safety.
• Normative references and harmonization: supplementary references (e.g., ISO 11372) and relationship with transport regulations (RID/ADR) noted in the standard.

Applications - who uses EN ISO 13088:2012

• Gas producers and filling plants - to implement safe acetylene bundle filling procedures and inspection routines.
• Cylinder manufacturers and bundling equipment suppliers - for design and marking requirements, and to confirm compatibility with porous materials and solvent types (e.g., acetone, DMF).
• Inspection bodies and safety auditors - to verify compliance during pre-fill, in-process and post-fill checks.
• Transport and logistics operators - to ensure bundles meet packing, marking and documentation requirements for road/rail transport (ADR/RID).
• Regulators and standards committees - for harmonization of national requirements and incorporation into national standards.
