1. Introduction<br />
In all European countries, the valve outlet connections for gas cylinders have been developed more or<br />
less independently from each other. The consequence is that for one gas, different connections are<br />
being used across Europe. Although the connections used in the respective countries are safe they<br />
are not compatible with those used in other countries.<br />
This Document was prepared to facilitate harmonisation of the gas cylinders valve outlets across<br />
Europe.<br />
The wish of the Industry is to have the possibility to keep the national valves outlets. The NEVOC<br />
(New European Valve Outlet Connections) system is intended to be used in case of the need for new<br />
outlets to facilitate future harmonisation.<br />
The industry (EIGA Companies) have agreed to commit themselves to use, in case of the need for<br />
new outlets, the ones corresponding to the NEVOC system.<br />
For example, if for a 200 bar outlet 2 different groups of gases are used, e.g. same outlet for oxygen<br />
(oxidising) and nitrogen (asphyxiating) and if this country decides to differentiate oxidising gases from<br />
asphyxiating gases, the corresponding oxidising and asphyxiated outlet of the NEVOC system should<br />
be used. Another example concerns new applications such as 300 bar outlets; the corresponding 300<br />
bar outlet of the NEVOC system shall be used.<br />
The current national connections systems are listed in part 1 of this document. They can continue to<br />
be used in the country concerned. The new connections system is based on ISO 5145 and represents<br />
a «New European Valve Outlet Connections (NEVOC)<br />
2. Scope<br />
This document applies to valve outlet connections for gas cylinders. Part 1 lists the outlet connections<br />
which at present are being used in the CEN members states.<br />
Part 2 explains how to select a new valve outlet connection from ISO 5145.<br />
Part 1<br />
Valve outlet connections for gas cylinders listed in part 1 (national connections) may be used in those<br />
CEN member states, which are assigned to the respective connections.<br />
In the event that the current national connections are being replaced by new ones, for whatever<br />
reasons, then connections according to part 2 of this document should be chosen.<br />
Part 2<br />
This describes the valve outlet connections for gas cylinders, which represented a New European<br />
Outlet Connection (NEVOC) based upon ISO 5145.<br />
Note<br />
The following are excluded from this document:<br />
• Ultra high integrity service valve outlets (see ISO 10692-1).<br />
• Valve outlets for small medical gas cylinders (< 5 litres) see EN 850 and ISO 407.<br />
• Valve outlets for LPG cylinders (but included are valve outlets for pure Propane, Butane).<br />
• Valve outlets for cryogenic gas withdrawal.<br />

4. Part 2: New European Valve Outlet Connections (NEVOC) recommendation<br />
EIGA recommends, that if there is a requirement for a new valve outlet, e.g. due to pressure increase,<br />
new gas mixture or for a new medical gas mixture, then the valve outlet corresponding to this new<br />
application shall be selected in accordance with the latest version of ISO 5145 2003.<br />

6. Adapters<br />
Due to the fact that it is expected to have two parallel valve outlet connection systems in Europe for a<br />
long period of time:<br />
a) National valve outlet standards (Part1)<br />
b) New European valve outlet connections (Part 2)<br />
There are two choices to provide interchangeability:<br />
1) Equipment used connected to the cylinder valve should be changed to the appropriate valve<br />
outlet connection of the new European valve outlet connection in order to ensure safe operation.<br />
2
<strong>IGC</strong> DOC 97/03<br />
2) Where problems occur to change the equipment together with the valve outlet connection,<br />
adapters may be used.<br />
Where the use of adapters is unavoidable, only the adapters shown in this standard (see Part 2,<br />
annex 1) shall be used and carefully controlled.<br />
This Document recognises adapters designed to connect a cylinder valve outlet to a regulator,<br />
charging connection or other mating part having a different connection for the same gas and<br />
pressure. Adapters are permitted for standard connections between standard (Part 2) and limited<br />
national standard connections (Part 1) for the same gas, unless the use of such adapters could<br />
result in undesirable connections. For example,. even for the same gas, adapters must not be<br />
used which connect a high pressure source to equipment rated at a lower pressure. Other<br />
adapters may be used by suppliers of gases or related equipment at their facilities.<br />
An example of what could be one of these safe adapters is given in part 2, annex 1.<br />
