ISO 5772:2015

Overview

ISO 5772:2015 - "Rubber and plastic hoses and hose assemblies for measured fuel dispensing systems - Specification" - defines minimum technical and performance requirements for hoses and hose assemblies used in measured fuel dispensing (including oxygenated fuels up to 15% oxygenates). The standard covers three hose types, two electrical categories and two low‑temperature classes for ambient service from −40 °C (low‑temperature class) or −30 °C (normal class) up to +55 °C, and a maximum working pressure of 16 bar (1,6 MPa).

Key topics and technical requirements

• Hose types and classification
  • Type 1: textile reinforced
  • Type 2: textile plus helical wire reinforced
  • Type 3: fine wire reinforced
  • Two temperature classes: normal (−30 °C to +55 °C) and low temperature (−40 °C to +55 °C)
  • Two electrical categories: M (metallic bonding wires) and Ω (conductive compounds)
• Materials and construction
  • Smooth, fuel‑resistant rubber or thermoplastic elastomer (TPE) linings; weather- and fuel‑resistant covers
  • Hoses with metallic bonding must embed at least two metallic wires for electrical continuity
• Pressure performance
  • Maximum working pressure: 16 bar (1,6 MPa)
  • Proof pressure: 24 bar (2,4 MPa)
  • Minimum burst pressure: 48 bar (4,8 MPa)
• Dimensional and mechanical limits
  • Minimum lining thickness: 1.6 mm; cover thickness: 1.0 mm
  • Concentricity tolerance ≤ 1.0 mm
  • Specified internal diameters, bend radii, and length tolerances (measured per ISO 4671 / ISO 1307)
• Physical properties and tests
  • Compound requirements (tensile strength: rubber ≥ 9 MPa, TPE ≥ 12 MPa; elongation and ageing limits)
  • Finished‑hose requirements: proof/burst testing, volumetric expansion, adhesion between components, low‑temperature flexibility, no leakage, permeation and flammability controls
  • Extensive normative annexes (A–I) specifying low‑temperature tests, adhesion after fuel ageing, permeation, flammability, end‑fitting pull‑off, flex/fatigue, leak testing, and test frequencies

Practical applications and users

• Typical users: hose manufacturers, dispenser OEMs, fuel retail operators, quality/compliance engineers, and test laboratories
• Applications: fuel dispensing hoses and assemblies on retail forecourts, measured dispensing installations, and systems handling gasoline, diesel and oxygenated fuel blends (up to 15% oxygenates)
• Value: ensures safe pressure performance, electrical continuity (to prevent static build‑up), low‑temperature flexibility, fuel compatibility and reduced permeation and flammability risk

Related standards

• ISO 1402 (hydrostatic testing), ISO 8033 (adhesion), ISO 4671 (dimensional measurement), ISO 10619‑1 (bending tests), ISO 1817 (resistance to liquids), ISO 6801 (volumetric expansion) - referenced within ISO 5772:2015 for test methods and measurement guidance.
