Foreword
The text of EN ISO 13340:2001 has been prepared by Technical Committee CEN/TC 23
"Transportable gas cylinders", the secretariat of which is held by BSI, in collaboration with
Technical Committee ISO/TC 58 "Gas cylinders".
This European Standard shall be given the status of a national standard, either by publication of
an identical text or by endorsement, at the latest by October 2001, and conflicting national
standards shall be withdrawn at the latest by October 2001.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Czech
Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This Standard specifies requirements for gas cylinder valves to be used with non refillable
cylinders and the method of testing such valves for prototype approval.
NOTE Non refillable gas cylinders are specified in prEN 12205:1998 and ISO/FDIS 11118:1999.
This Standard is not applicable to valves for breathing equipment, fire extinguishers and cryogenic
equipment.

3 Terms and definitions
For the purposes of this standard, the following definitions apply :
3.1
working pressure (p )
w
settled pressure, at a uniform temperature of 15 °C, for a full gas cylinder
3.2
valve test pressure (p )
vt
for compressed gases:
p = 1,2 x p
vt w
For liquefied gases and dissolved gases under pressure (for example, acetylene), p is at least
vt
equal to the minimum test pressure of the cylinder quoted in the relevant transportation regulation
for that gas or gas group, taking account of the actual filling ratio to be used.
NOTE : Transportation regulations sometimes offer a choice of filling ratio together with
appropriate minimum test pressures. Generally, p will be the highest of these minimum test
vt
pressures for the gas, but in circumstances where a lower filling ratio is to be used, p may
vt
be an appropriate lower test pressure.
3.3
single use operating mechanism
a mechanism which when opened once will not reseal
4 Valve requirements
4.1 General
Valves shall operate satisfactorily over the full range of service temperatures, normally from
- 20 °C to + 65 °C. The range may be extended for short periods (e.g. during filling).
Where higher or lower service temperatures are required for longer periods, the purchaser shall
specify accordingly.
Valves shall be capable of withstanding the mechanical stresses and chemicals they may
experience during normal operation.
The valves shall be cleaned to meet the requirements of the intended service.
4.2 Description
The cylinder valve shall comprise :
- a body ;
Page 5
- a valve operating mechanism and sealing device ;
- connection(s) for use (fill and discharge) ;
- a connection system, between the valve and gas cylinder ;
and may occasionally incorporate :
- a safety device against overpressurisation ;
- a dip tube ;
- a screw plug or cap on the outlet connection, to ensure leak tightness or protection ;
- an excess flow limiting device.
4.3 Materials
Metallic and non-metallic materials in contact with the gas shall be chemically and/or physically
compatible with the gas under all intended operating conditions (as specified in EN ISO 11114-1
and EN ISO 11114-2).
Where valves may come into contact with oxygen or other oxidizing gases then compatibility of
materials with these gases and ignition resistance of materials and lubricants, shall be established
by an appropriate test procedure (see for example EN ISO 11114-3).
Valves for acetylene may be manufactured from copper
