Overview
ISO 9159:1988 - "Road vehicles - Nozzle spouts for leaded gasoline and diesel fuel" specifies the dimensional and performance requirements for pump nozzle spouts used to refuel road vehicles. The standard defines physical geometry, safe hooking features (spring, cams or depressions), and permitted filling rates to ensure compatibility with vehicle tank filler openings and safe, reliable fuel dispensing. It applies to nozzle spouts for leaded gasoline and diesel fuel.
Key topics and requirements
- Scope: Dimensions and filling rates for nozzle spouts intended for road-vehicle refuelling; includes spouts with a spring or with cams/depressions for safe hooking in the tank filler opening.
- Flow (filling) rates:
- For leaded gasoline: qv < 50 Vmin.
- For diesel fuel: either qv < 50 Vmin or 50 Vmin < qv < 100 Vmin depending on spout dimensions (see standard figure).
- Dimensional controls (selected parameters from ISO 9159:1988):
- Nozzle pipe straight length: typically 80–95 mm for lower-flow spouts and 65–90 mm for higher-flow diesel spouts.
- Distance from nozzle end to sensor: ≤ 22 mm.
- Clearance from fuel-dispensing end to any nozzle body part: ≥ 165 mm (or 170–200 mm for certain diesel spouts).
- Anchor/spring outside diameter: ≤ 30 mm or ≤ 38 mm depending on spout class.
- Nozzle pipe bending radius: ranges such as 100–250 mm (lower-flow) and 120–160 mm (higher-flow).
- Bending angle of nozzle pipe: 21° ± 1.5°.
- Safe hooking details: The standard illustrates a nozzle spout with a spring-mounted hook and states that dimensions equally apply to spouts using cams or depressions for secure engagement with the tank filler opening.
- Manufacturer discretion: Overall spout shape may be chosen by the manufacturer provided the specified dimensions and functional requirements are met.
Applications and users
ISO 9159:1988 is used to ensure interoperability and safety across the fuel supply chain. Typical users include:
- Fuel dispenser and pump nozzle manufacturers designing spouts for gasoline and diesel dispensing.
- Petrol station equipment engineers and fuel station operators ensuring compliance and safe refuelling.
- Vehicle manufacturers and fuel-filler system designers verifying compatibility with filler openings.
- Testing and certification laboratories, regulators and standards bodies responsible for safety certification and compliance testing.
- Maintenance and aftermarket suppliers replacing or specifying nozzles for legacy systems.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Each member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures ‘requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 9159 was prepared by Technical Committee ISO/TC 22,
Road vehicles.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
