Rubber and plastics hoses, tubing and assemblies for use with propane and butane and their mixtures in the vapour phase - Part 1: Hoses and tubings

EN 16436-1+A3 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).

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:

tubing
single core of plastic or rubber with no reinforcement or cover

hose
rubber or flexible thermoplastic lining with a reinforcement made of natural or synthetic textile
material applied either spirally wound or braided, and a flexible rubber or thermoplastic outer cover
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.

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
- white for classes 1 and 2 with the marking above, on, or below a continuous orange line of 5 mm
minimum width (see Figure 2).
