Overview

SIST EN ISO 1825:2026 specifies the requirements for rubber hoses and hose assemblies used in the ground fuelling and defuelling of aircraft. This harmonized European and international standard is issued by CEN and aligns with ISO 1825, supporting the safe and reliable transfer of petroleum fuels at airports and other aircraft servicing locations. The standard covers four types of hoses with specific temperature and pressure ratings, ensuring compatibility with aviation fuels and resilience under various operational and environmental conditions.

Key features of SIST EN ISO 1825:2026 include specification of hose dimensions, construction, electrical properties, physical characteristics, and test methods, thus enabling consistency and safety in ground support equipment for the aviation sector.

Key Topics

Scope and Purpose
- Defines requirements for rubber hoses and hose assemblies used in ground fuelling and defuelling operations for aircraft.
- Covers four hose types designed for use with petroleum fuels containing up to 30% aromatic hydrocarbons by volume.
- Specifies performance criteria for operation between −30 °C to +65 °C, with storage tolerance from −40 °C to +70 °C, and an LT (low temperature) class accommodating −40 °C to +65 °C operation, with storage down to −48 °C.
Hose Types and Classes
- Four main types with distinctions in electrical bonding and construction.
- Each type supports standard and low-temperature operation.
Pressure and Safety
- Designed for maximum working pressure of 2.0 MPa (20 bar), including pressure surges during use.
- Robust against climatic variation and mechanical stresses encountered during airport ground operations.
Physical and Electrical Properties
- Requirements for tensile strength, elongation, volume change in fuel, abrasion resistance, and ageing.
- Detailed guidance on bonding and continuity for safe dissipation of static electricity during fuel transfer.
- Marking and traceability mandates for compliance and safety audits.
Testing and Certification
- Outlines frequency and procedures for type and routine tests.
- Mandates test certificates or reports upon request, detailing manufacturer, product identification, hose classification, and testing results.

Applications

SIST EN ISO 1825:2026 is critical across multiple aviation ground operations, supporting:

Airport Fuel Farms and Dispensing Vehicles
- Safe, reliable hoses for fuelling and defuelling commercial, military, and private aircraft.
Maintenance and Servicing
- Hose assemblies tailored for aviation GSE (Ground Support Equipment), ensuring predictable performance and easy maintenance.
Fuel Storage and Transfer
- Hoses for road and rail fuel tankers engaged in transferring aviation fuel between storage, vehicles, and aircraft.
Compliance and Safety Management
- Enables operators to meet regulatory and quality management requirements for safe handling of hazardous aviation fuels.

Related Standards

Organizations using SIST EN ISO 1825:2026 may also refer to related and supporting standards, including:

ISO 1402 - Hydrostatic testing of rubber and plastics hose assemblies.
ISO 1817 - Determination of the effect of liquids on rubber.
ISO 4649 - Abrasion resistance assessment of rubber.
ISO 4671 - Methods for measuring hose dimensions.
ISO 6246 - Jet fuel gum content testing.
ISO 7326 - Ozone resistance testing for hoses.
ISO 8031 - Measurement of electrical resistance and conductivity.
ISO 10619-2 - Flexibility and stiffness testing at sub-ambient temperatures.

SIST EN ISO 1825:2026 is a cornerstone for aviation ground fuelling safety, ensuring hoses and hose assemblies perform dependably, resist fuel degradation, and meet rigorous international quality and safety benchmarks. Adopting this standard helps operators reduce risk, promote equipment longevity, and maintain compliance with global aviation industry best practices.
