Overview

CEN/TR 15444:2006 is a European Technical Report providing the rationale and technical justification for using transportable gas cylinders, manufactured under the Transportable Pressure Equipment Directive (TPED), in applications governed by the Pressure Equipment Directive (PED). This standard facilitates harmonization between TPED and PED by confirming equivalence in safety levels, allowing gas cylinders originally designed for transport purposes to be eligible for the "CE" mark when utilized under PED-regulated applications.

The scope addresses cylinders used in portable fire extinguishers, breathing apparatus, and stationary pressure vessels-subject to filling conditions meeting ADR/RID regulations. This report supports compliance with essential safety requirements (ESRs) of the PED by demonstrating that TPED-certified transportable gas cylinders meet or exceed PED safety provisions.

Key Topics

• Scope and Applicability:
  The report justifies that transportable gas cylinders conforming to TPED can also fulfill PED requirements, given appropriate filling conditions under international carriage regulations (ADR/RID).

• Referenced Standards:
  Key European standards underpinning this report include:

  • EN 1964 Parts 1-3 for seamless steel cylinders
  • EN 1975 for aluminium alloy cylinders
  • EN 12245 and EN 12257 for composite cylinders
  • EN 13322-1 for welded steel cylinders
    These standards govern design, manufacturing, and testing protocols ensuring cylinder safety and performance.

• Materials Standards:
  Steel and aluminium alloys used in cylinder manufacture must meet stringent composition and mechanical property requirements to ensure gas compatibility and durability, as detailed in EN ISO 11114 parts 1–3.

• Safety and Testing:
  The Technical Report outlines the equivalence of safety factors between TPED and PED, including:

  • Hydrostatic proof testing at prescribed pressures
  • Pressure cycling and burst tests for new designs
  • Batch conformity testing including mechanical and burst properties
  • Individual cylinder testing such as pressure, visual, dimensional, and hardness checks
  • Additional advanced tests like fatigue, creep, and extreme temperature cycling for specific materials

• Marking and Certification:
  Cylinders must bear markings in accordance with EN ISO 13769 and display the "CE" mark signalling compliance with the PED.

Applications

• Portable Fire Extinguishers:
  Cylinders designed and manufactured to TPED standards can be safely used in portable fire extinguishers meeting PED requirements.

• Breathing Apparatus:
  High-pressure cylinders for breathing apparatus benefit from compliant design and safety assurance, enabling usage across transport and stationary applications.

• Stationary Pressure Vessels:
  Cylinder designs applicable to stationary pressure vessels within PED’s scope can utilize the TPED-certified cylinders provided filling and operational conditions conform to stipulated regulations.

This report offers practical assurance to manufacturers and regulatory bodies that transportable gas cylinders can serve multifunctional roles without compromising safety, thereby streamlining certification, manufacturing, and operational processes.

Related Standards

• Transportable Pressure Equipment Directive (TPED) 99/36/EC: Regulates the safety requirements for transportable pressure equipment.

• Pressure Equipment Directive (PED) 97/23/EC: Governs design and manufacture of pressure equipment used in stationary applications.

• ADR/RID Regulations: Address international carriage conditions for dangerous goods by road (ADR) and rail (RID).

• EN ISO 11114 Series: Defines compatibility requirements between cylinder materials and gases.

• EN ISO 13769: Specifies standardized marking for gas cylinders.

• EN 1919 and EN 1920: Concern inspection protocols at the time of filling transportable gas cylinders.

This suite of interconnected standards supports compliance assurance for gas cylinder manufacturers and users, emphasizing safety, reliability, and regulatory harmony across EU legislation and international transport guidelines.

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
