Overview
EN ISO 10462:2013 - published by CEN as the European adoption of ISO 10462:2013 - specifies requirements for the periodic inspection and maintenance of acetylene cylinders used for the transport of dangerous goods. It applies to acetylene cylinders (with or without solvent) up to a maximum nominal water capacity of 150 L. The standard is intended for use alongside national transport and safety regulations and supersedes EN 12863:2002.
Key topics and technical requirements
The standard focuses on acetylene-specific inspection needs that differ from other gas cylinders, notably because acetylene cylinders contain porous material (and usually solvent) to limit decomposition risks. Major technical topics include:
- Scope and applicability: cylinders with/without solvent, max 150 L capacity.
- Inspection authority and competence: inspections must be performed by competent or, where required, authorized persons.
- Preparation: safe depressurization, valve removal procedures (references ISO 13341 for fitting/removal).
- External visual inspection: condition of shell, neck and fittings; updated procedures provided (see normative Annex B).
- Porous material inspection: assessment for cracking, crumbling, cavities or voids; requirements for replacement or addition of porous material and procedures for monolithic porous materials.
- Valve and fusible plug inspection: valve inspection referenced to ISO 22434; fusible plug checks specified.
- Reassembly, marking and records: marking of inspection dates, rings/indicators, and required documentation of inspections.
- Rejection and disposal: criteria for rendering cylinders unserviceable and safe disposal methods.
Note: inspection intervals are governed by relevant transport/safety regulations and are not fixed in this standard.
Practical applications and users
EN ISO 10462:2013 is used by:
- Cylinder inspection and maintenance shops
- Transport operators and fleet managers handling acetylene
- Gas suppliers and distributors
- Regulatory authorities and safety auditors
- Manufacturers of acetylene cylinders and porous media
Practical benefits include safer transport compliance, reduced risk of acetylene decomposition incidents, consistent inspection records, and guidance for repair, reconditioning or safe rejection/disposal.
