Overview
ISO 9158:1988 is an international standard developed by the International Organization for Standardization (ISO) that specifies the dimensions and filling rates of nozzle spouts used for refuelling road vehicles with unleaded gasoline. This standard ensures compatibility and safety in fuel dispensing equipment by defining precise nozzle spout measurements, including features like spring hooks or cams for secure attachment during refuelling. The standard applies specifically to nozzle spouts designed for unleaded gasoline, addressing both geometric dimensions and maximum fuel flow rates.
Key Topics
Dimensional Specifications
ISO 9158:1988 defines exact dimensions in millimeters for nozzle spouts, including:- Maximum outer diameter of the nozzle spout (21.3 mm)
- Maximum diameter of the spring hook (30 mm)
- Lengths of various nozzle spout segments (e.g., 80–95 mm straight tube length)
- Radii and angles for bending the spout tube (100–250 mm radius, 21° bending angle)
- Clearances between fuel outlet and nozzle body to ensure safe fuel flow
Flow Rate Requirement
The maximum allowable filling rate (flow rate) for unleaded gasoline nozzles is capped at 50 liters per minute, supporting efficient yet controlled fuel delivery to prevent spillage or safety risks.Hooking Mechanisms
To improve safety and ease of use, the standard allows for nozzle spouts equipped with either springs, cams, or depressions to secure the spout firmly in the vehicle’s filler opening during refuelling.Reference to Related Standards
ISO 9158 references ISO 4130 regarding dimensional reference systems and fuel dispensing positions, ensuring cohesive practices across related refuelling components.
Applications
Fuel Dispensing Equipment Manufacturers
Producers of fuel nozzles and pumps utilize ISO 9158 to design and manufacture nozzles that meet international safety and compatibility benchmarks, facilitating global market acceptance.Petrol Stations and Fuel Retailers
Compliance with ISO 9158 ensures that refuelling equipment provides safe and efficient fuel delivery, minimizing environmental hazards, fuel wastage, and equipment damage.Automobile Manufacturers
Ensuring fuel tank filler designs accommodate standardized nozzle spouts as specified in ISO 9158 guarantees compatibility with fueling infrastructure worldwide.Safety and Regulatory Compliance
Regulatory bodies may reference ISO 9158 to enforce standards on petrol station equipment, promoting operational safety and interchangeability of fuel dispensing systems.
Related Standards
ISO 4130 – Road vehicles: Dimensional reference system and designations for vehicle components, which is referenced for defining angular and positional criteria of nozzle spouts.
ISO/TC 22 – Technical Committee responsible for all road vehicle standards, including fuel dispensing equipment and compatibility norms.
Other Fuel Dispensing Standards – Depending on the region and fuel type, supplementary standards may complement ISO 9158 for diesel nozzles or alternative fuels, ensuring comprehensive coverage for refuelling systems.
By adhering to ISO 9158:1988, manufacturers and operators ensure that unleaded gasoline nozzle spouts meet internationally recognized safety, ergonomic, and performance criteria. This standard supports consistency in fuel dispensing infrastructure, facilitating safer, more efficient refuelling of road vehicles worldwide.

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 9158 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.
