Proposes to introduce a number of new connections which will fully differentiate the valve outlets by gas and maximum filling pressure. It is intended to introduce connections from ISO 5154 for air and permanent inert gases for filling pressures up to 20 700 kPa at 15 degrees Celsius. This will allow specific oxygen only connections, with the existing Type 10 connection being retained for pressures up to 17 500 kPa at 15 degrees Celsius and the introduction of a new connection, a Type 10.5 for pressures up to 20 700 kPa at 15 degrees Celsius. Other connections are proposed for pressures up to 25 000 kPa and 31 500 kPa both at 15 degrees Celsius. For air, inert gases and high-pressure flammable gases, connections are introduced for filling pressures up to 31 500 kPa and 42 500 kPa, both at 15 degrees Celsius.
