TS EN 16436-1+A2

TS EN 16436-1+A2 is the standard for rubber and plastics hoses and tubing used with propane, butane, and their mixtures in the vapour phase. It sets out the technical requirements for hose and tubing assemblies used in connections between a pressure gas cylinder, a pressure regulator, and associated equipment.

The subject is flexible gas-conveying components intended for LPG-related vapour-phase service. In this type of application, the hose or tubing must support safe and reliable connection performance under pressure, temperature variation, and normal service ageing. The stated operating range of 0 bar to 30 bar and the ambient temperature range from -30 °C to +70 °C show that the product family is intended for demanding outdoor and indoor service conditions, not for general-purpose fluid transfer.

Where this standard draws the line

• This part applies only to hoses and tubing; the equipment itself is covered by EN 16436-2.
• It is intended for commercial propane, commercial butane, and their mixtures in the vapour phase.
• It covers connections between a pressure gas cylinder, a regulator, equipment, and installation piping.
• Three classes are defined in Table 1 according to maximum working pressure and minimum ambient temperature.
• Hoses for welding, propulsion, and LPG transport are excluded from this scope.

From a general engineering perspective, rubber and plastic hoses differ in flexibility, temperature response, and ageing behaviour, which is why gas-service products are specified separately from ordinary hose products. Standards in this area help align the hose construction and service envelope with the gas type, pressure, and installation context. The A2 designation indicates an amendment to this edition; it does not change the fact that the listed subject is the hose and tubing part of the series.
