Overview
EN 1762:2018 is a CEN European Standard specifying requirements for rubber hoses and hose assemblies used to transfer liquefied petroleum gas (LPG) (liquid or gaseous phase) and natural gas. It covers hoses and assemblies with a maximum working pressure of 25 bar (2,5 MPa) and vacuum service over the temperature range −30 °C to +70 °C, and −50 °C to +70 °C when designated -LT (low temperature). The standard defines construction, materials, dimensions, electrical and physical properties, testing, marking and production/test frequencies.
Key Topics and Requirements
- Scope and classification
- Five hose types: D, D‑LT, SD, SD‑LTS, SD‑LTR (delivery, suction/delivery, low temperature and rough-bore variants).
- Three electrical grades: M (electrically bonded), electrically conductive, and electrically discontinuous.
- Materials & construction
- Lining of synthetic rubber resistant to n‑pentane.
- Reinforcement: textile layers or stainless steel wire; types SD include an embedded stainless steel helix.
- Outer cover: black or coloured synthetic rubber, abrasion and weather resistant; may be pricked for permeation.
- Chlorinated materials must not contact stainless steel.
- Dimensions & mechanical
- Nominal bores cover a wide range (from ~12 mm up to 300 mm for built‑in couplings).
- Minimum lining and cover thickness: 1.6 mm.
- Concentricity, tolerances on length (±1 %) and specified minimum bend radii are defined.
- Physical & electrical properties
- Compound requirements: min. tensile strength 10 MPa, min. elongation 250%, abrasion and ageing limits, resistance to n‑pentane and permeation tests for non‑pricked covers.
- Electrical behaviour (bonding wires or conductive layers) and assembly attachment per Clause 8.
- Testing & documentation
- Type testing, routine and production tests, flammability test (Annex A) and environmental checklist (Annex D).
- Marking requirements for hoses and hose assemblies.
Applications and Who Uses It
- Intended for manufacturers and assemblers of LPG and natural gas transfer hoses (fuel dispensers, filling stations, vehicle refuelling, industrial gas transfer).
- Used by design engineers, safety and compliance officers, procurement specialists, testing labs and certification bodies to specify, evaluate and accept hoses and assemblies.
- Relevant for infrastructure, equipment suppliers and installers who must meet regulatory and safety standards for gaseous and liquid hydrocarbon handling.
