Foreword
This document (CEN/TR 15444:2006) has been prepared by Technical Committee CEN/TC 23 “Transportable
gas cylinders”, the secretariat of which is held by BSI.

Introduction
This CEN technical report has been prepared to address the essential requirements of the Pressure
Equipment Directive (PED) 97/23/EC with regard to European Standards prepared originally for transportable
gas cylinders, which address the essential safety requirements of the Transportable Pressure Equipment
Directive (TPED) 99/36/EC.
1 Scope
This Technical Report provides a rationale and technical justification for certain European Standards for
transportable gas cylinders, produced in accordance with the requirements of the Transportable Pressure
Equipment Directive (TPED), to be used for applications currently listed in the Pressure Equipment Directive
(PED). Its purpose is to prove equivalence of approach in the two directives and demonstrate equivalence to
the overall level of safety in the Essential Safety Requirements (ESRs) of the PED, thereby allowing European
Standards and EEC directives listed in this Technical Report to be used to fulfil the requirements of the PED,
provided that their filling conditions fulfil the requirements of ADR/RID (P200, 4.1.4.1), in respect of portable
fire extinguishers and breathing apparatus.

4 Technical justification
4.1 General
The following standards, together with those referred to in the Bibliography, have been produced to support
the essential requirements of the TPED.
— EN 1964-1, -2 and -3 for seamless steel cylinders;
— EN 1975 for seamless aluminium alloy cylinders;
— EN 12245 for fully wrapped, composite cylinders;
— EN 12257 for hoop wrapped, composite cylinders;
— EN 13322-1 for welded steel cylinders.
They have been adjudged by the experts to conform to the requirements of the TPED, the Regulations
concerning the International Carriage of Dangerous Goods (RID) and the European Agreement on the
International Carriage of Dangerous Goods by Road (ADR). Gas cylinders are manufactured using stock
materials which are transformed to their final shape, then carefully heat treated and finally tested to well
defined criteria. Hence the manufacture of gas cylinders follows a different approach from that of conventional
pressure vessels. In the case of gas cylinders, the mechanical properties of the final product are significantly
altered during the manufacturing process from those of the stock materials. Consequently the mechanical
properties of the stock materials, guaranteed by material standards, are of little relevance.
4.2 Application
4.2.1 General
It is proposed by this Technical Report that cylinders manufactured in accordance with the design and
manufacturing standards quoted in 4.1 are suitable for the design and construction of seamless or welded
portable fire extinguishers and breathing apparatus (see clause 1.1 (a) of Article 3, PED). The dimensions of
these cylinders should reflect the limits in the various standards.
4.2.2 Materials
a) Steels
Materials used in the steel cylinder design standards and EEC Directive 84/525 need to meet stringent
mechanical properties. Hence their composition is defined according to a narrow specification, as is the
manufacturing process e.g. non-ageing, non-rimming quality steel is stipulated. Additionally full materials’
compatibility with the gas contained is an essential, normative requirement in gas cylinder manufacturing
standards (EN ISO 11114-1 refers).
b) Aluminium alloys
Materials used in the aluminium alloy cylinder design standards and EEC Directive 84/526 are referred back
to recognised and registered compositions wit
