According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of

1 Scope
This European Standard specifies the characteristics and performance requirements for tubing and
hoses made of either rubber or plastics for use with commercial propane and commercial butane and
mixtures thereof, in the vapour phase, for connection of appliances, from:
— pressurized gas container to a regulating device,
— pressurized gas container to an appliance,
— regulating device to an appliance, and
— regulating device to installation pipework,
in environments of a temperature range from –30 °C to +70 °C. Working pressures are from 0 bar to 30
bar.
Three classes are defined in Table 1 according to the maximum working pressures and minimum
ambient temperatures.
This European Standard only covers the tubing or hose part of assemblies. The assemblies themselves
will be covered by EN 16436-2.
This European Standard does not apply to hoses for:
— welding purposes (see EN ISO 3821, EN 1327);
— propulsion purposes;
— LPG transfer purposes (see EN 1762).

4 Classification of tubing and hose
One class of tubing and two classes of hose are specified in Table 1 depending on the maximum working
pressure and minimal ambient temperatures.
Table 1 — Classification of tubings and hoses
Class Maximum working pressure Minimum ambient temperature
bar °C

NOTE Classes 1 and 2 are usually used downstream of a pressure regulating device.
5 Materials and construction of tubing and hoses
Class 1 tubing shall be made of rubber or thermoplastic material.
Class 2 and class 3 hoses shall comprise a
— rubber or thermoplastics lining;
— reinforcement of natural or synthetic fibres applied either spirally wound or braided;
— rubber or plastics cover. The outer cover may be pricked to allow any gas trapped between the
inner lining and outer cover to be released.
The surface colour of the tubing or hose shall be:
- orange (see Figure 1a); or
- black with the marking above, on, or below a continuous orange line of 5 mm minimum width (see
Figure 1b); or
