TS EN 16436-1

TS EN 16436-1 addresses the technical requirements for rubber or plastic hoses and tubing used with commercial propane, commercial butane, and mixtures of these gases in the vapour phase. It defines the hose or tubing element used in connections between a pressurized gas container, a regulator, an appliance, and installation pipework; it does not cover the appliance itself, only the hose or tubing portion of the assembly.

The subject matter is specifically vapour-phase LPG service rather than liquid transfer. That distinction matters because pressure behavior, temperature exposure, flexibility, and material compatibility are different in gaseous service. The standard is framed for ambient temperatures from –30 °C to +70 °C and working pressures from 0 bar to 30 bar, which reflects the operating envelope for typical connection hoses in this field.

Classes and application boundaries

EN 16436-1 defines three classes according to maximum working pressure and minimum ambient temperature. In general engineering terms, this kind of classification helps match the hose or tubing construction to the expected service conditions, especially where low-temperature flexibility and pressure resistance are both relevant for LPG installations.

• Hoses for welding purposes are excluded and are covered by other standards.
• Hoses for propulsion purposes are also outside the scope.
• Hoses intended for LPG transfer are excluded as well.
• The assemblies themselves are covered by EN 16436-2.

As a result, TS EN 16436-1 provides the technical framework for the hose and tubing segment of LPG vapour-phase connections. It is best understood as a product standard for the connection element, helping distinguish suitable materials and service classes for use in gas installation contexts.
