Overview
EN 16436-1:2014+A3:2020 is a CEN European Standard that specifies the characteristics and performance requirements for rubber and plastics hoses and tubing used with commercial propane, commercial butane and their mixtures in the vapour phase. It covers hose/tubing used to connect appliances and pressure-regulating equipment (for example: pressurized gas container → regulator, regulator → appliance, and regulator → installation pipework) in ambient temperatures from −30 °C to +70 °C and working pressures up to 30 bar. The standard applies only to the hose or tubing part of assemblies (hose assemblies are addressed in EN 16436-2).
Key Topics and Requirements
- Scope and classification
- Defines three product classes according to maximum working pressure (examples: Class 2 up to 10 bar, Class 3 up to 30 bar) and minimum ambient temperature requirements.
- Materials & construction
- Tubing (single core) and hoses (lining, textile reinforcement - braided or spirally wound - and outer cover) in rubber or thermoplastic.
- Surface colour/marking options (orange; or black/white with a continuous orange line) for traceability and safety.
- Dimensions & tolerances
- Prescribes inside diameters, wall thicknesses and concentricity limits to ensure compatibility with fittings and consistent flow characteristics.
- Mechanical & chemical performance
- Tensile strength and elongation requirements (table includes minimums - e.g., Class 1 tubing shows 7.0 MPa and 250% elongation).
- Accelerated ageing, resistance to n‑pentane, ozone, UV exposure and permeability to propane.
- Pressure, integrity & durability tests
- Hydrostatic proof and burst tests, kinking/crushing resistance, low-temperature flexibility and adhesion between layers.
- Marking & cleanliness
- Identification, durability of marking and internal cleanliness (free from loose particles) are mandatory.
Applications and Users
- Who uses EN 16436-1
- Hose and tubing manufacturers for LPG applications, product designers, quality/test laboratories, certification bodies, equipment OEMs and procurement/specification engineers.
- Typical applications
- Flexible connections between LPG cylinders, pressure regulators and appliances (cookers, heaters, BBQs) where gas is in the vapour phase.
- Installation components where temperature and pressure ranges fall within the standard’s limits.
- Benefits
- Ensures safety, interchangeability and regulatory compliance for LPG hose products used in domestic and commercial appliances.
