Full title and description

ISO 2929:2021 — Rubber hoses and hose assemblies for bulk fuel delivery by truck — Specification. This International Standard specifies requirements for two groups of rubber hoses and hose assemblies used for loading and discharge of liquid hydrocarbon fuels (maximum working pressure 1,0 MPa / 10 bar), including construction, materials, performance and marking requirements for hose types intended for road tanker bulk fuel delivery.

Abstract

This document specifies requirements for two groups of rubber hoses and rubber hose assemblies for loading and discharge of liquid hydrocarbon fuels with a maximum working pressure of 1,0 MPa (10 bar). Hoses are intended for use with fuels having aromatic‑hydrocarbon content up to 50 % (v/v) and containing up to 15 % oxygenated compounds, and for operation in the temperature range −30 °C to +70 °C (storage static conditions −50 °C to +70 °C). The document excludes LPG systems, aviation fuel systems, fuel station systems and marine applications.

Scope

Specifies requirements for two groups of rubber hoses and hose assemblies for loading and discharge of liquid hydrocarbon fuels for road tankers, rated to a maximum working pressure of 1,0 MPa (10 bar). Designed for fuels with aromatic‑hydrocarbon content not exceeding 50 % by volume and up to 15 % oxygenated compounds, and for service temperatures −30 °C to +70 °C (storage static conditions −50 °C to +70 °C). Not applicable to hoses for LPG, aviation fuel systems, fuel station systems or marine applications.

Key topics and requirements

• Classification of hoses into the two groups (delivery and suction/delivery helix‑reinforced) with permissible uses and restrictions.
• Materials and construction: fuel‑resistant inner lining, reinforcement layers (textile, braid or spiral), helix for helix‑reinforced types, abrasion‑resistant outer cover and restrictions on release agents for mandrel‑built hoses.
• Electrical properties: provisions for electrically bonded (M‑grade) and electrically conductive (Ω‑grade) constructions and marking requirements.
• Dimensional and physical requirements: nominal bore/diameter tolerances, minimum lining/cover thickness, concentricity and minimum bend radius.
• Performance, type and routine tests: hydrostatic/burst testing, flexibility tests (ambient and sub‑ambient), tensile and ageing tests, adhesion tests between components, fuel resistance and flammability method annexes.
• Design verification (type) testing, frequency of testing and marking (hose and hose‑assembly identification and electrical grading).

Typical use and users

Used by manufacturers of rubber fuel hoses and hose assemblies, designers and specifiers for tanker unloading/loading equipment, fleet operators and transport companies handling bulk hydrocarbon fuels, testing and certification laboratories, procurement teams and regulatory bodies involved in road tanker equipment safety and compliance.

Related standards

ISO 2929 references and is used alongside other hose and rubber test standards, notably ISO 10619‑1 and ISO 10619‑2 (flexibility/stiffness tests), ISO 1402 (hydrostatic testing), ISO 37 (tensile properties of vulcanized rubber), ISO 188 (accelerated ageing), ISO 1817 (effect of liquids on rubber) and related electrical and flammability test methods referenced in the annexes. Many of these are listed as normative references in the ISO 2929 document.

FAQ

Q: What is this standard?

A: ISO 2929:2021 is an international specification that defines requirements and test methods for rubber hoses and hose assemblies used for bulk delivery of liquid hydrocarbon fuels by truck (road tankers).

Q: What does it cover?

A: It covers two groups of hoses intended for loading and discharge of liquid hydrocarbon fuels up to a maximum working pressure of 1,0 MPa (10 bar), including materials, construction, dimensional tolerances, electrical grading options, performance tests (hydrostatic, flexibility, tensile, ageing, adhesion, fuel resistance) and marking. It excludes LPG, aviation fuel, fuel station systems and marine applications.

Q: Who typically uses it?

A: Hose and hose‑assembly manufacturers, certification and test laboratories, tanker and fleet equipment specifiers, procurement teams and safety/regulatory authorities involved in bulk fuel transport and handling. (Common industry practice; see standard scope and application.)

Q: Is it current or superseded?

A: Current — published in September 2021 (5th edition). It replaces earlier editions of ISO 2929 (for example the 2014 edition).

Q: Is it part of a series?

A: ISO 2929 is a standalone specification for bulk fuel delivery hoses but is used together with a family of ISO hose and rubber test standards (for example ISO 1402, ISO 10619‑1/2, ISO 37, ISO 188, ISO 1817) that provide test methods and related requirements.

Q: What are the key keywords?

A: Rubber hoses, hose assemblies, bulk fuel delivery, road tanker, hydrocarbon fuels, hydrostatic testing, flexibility, fuel resistance, electrical bonding (M‑grade), electrical conductivity (Ω‑grade).
