Full title and description

ISO 15037-2:2002 — Road vehicles — Vehicle dynamics test methods — Part 2: General conditions for heavy vehicles and buses. This part of ISO 15037 specifies general test conditions, environmental and vehicle preparation requirements and reporting details to be used when determining vehicle dynamics properties of heavy commercial vehicles, combinations and buses.

Abstract

ISO 15037-2:2002 defines the general conditions that apply when vehicle dynamics properties are determined according to ISO test methods for heavy vehicles and buses (vehicle categories as defined in ISO 3833 and UNECE/EC classifications). It covers required variables, measuring equipment and data processing, test environment (track and wind), vehicle preparation, tyre treatment and the format of test reports.

General information

• Status: Published.
• Publication date: December 2002 (ISO catalogue: 2002-12).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 43.080.01 (Commercial vehicles in general).
• Edition / version: Edition 1 (2002).
• Number of pages: 18 (official ISO record).

Scope

This standard applies to heavy road vehicles and buses (trucks, trailers, articulated buses and combinations) as defined in ISO 3833 and UNECE/EC vehicle classification (categories such as M3, N2, N3, O3 and O4). It establishes the general ambient and track conditions, vehicle set-up, instrumentation and reporting requirements that shall be observed when performing ISO vehicle-dynamics test methods for these vehicle classes.

Key topics and requirements

• Definitions of applicable vehicle categories and reference to ISO 3833 for classification.
• Environmental and track conditions (paving, surface recording, and wind limits — e.g., ambient wind velocity limits during tests).
• Test-vehicle preparation: loading, mass distribution, tyre specification and run-in procedures (for standard tests new tyres run-in for at least ~150 km unless otherwise specified).
• Tyre-related requirements: tread depth criteria, storage/manufacture age reporting and inflation-pressure tolerances for cold pressures.
• Instrumentation and data processing: general requirements for measurement equipment, signal sampling and reporting formats to ensure repeatability and comparability.
• Test reporting: mandatory recording of vehicle general data, environmental/test conditions and tyre details (annexes define report formats and data to record).

Typical use and users

Primary users include vehicle test laboratories, vehicle manufacturers (OEMs), component suppliers, regulatory bodies and research organisations performing dynamic testing of heavy vehicles and buses for development, validation and regulatory or conformity assessments. Test engineers and data analysts use the standard to ensure consistent test set-up and comparable results across trials and organisations.

Related standards

ISO 15037 is a multi-part series. Closely related parts and updates include ISO 15037-1 (general conditions for passenger cars; later editions published, e.g. ISO 15037-1:2019) and more recent parts addressing ride comfort and other test classes (for example ISO 15037-3 published in 2022 covering passenger-car ride-comfort test conditions). Users should consult the ISO 15037 series and ISO 3833 for vehicle classification details.

FAQ

Q: What is this standard?

A: ISO 15037-2:2002 is the International Standard that defines general test conditions and requirements to be used when performing vehicle-dynamics tests on heavy vehicles and buses.

Q: What does it cover?

A: It covers environmental and track conditions, vehicle preparation and loading, tyre treatment and specification, measurement/instrumentation basics, and the content/format of test reports for heavy vehicles and buses. Annexes provide reporting templates and additional guidance.

Q: Who typically uses it?

A: Vehicle OEM test teams, independent vehicle dynamics laboratories, component suppliers, regulators and research organisations conducting on-road dynamic tests of trucks, trailers and buses.

Q: Is it current or superseded?

A: ISO 15037-2 was published in December 2002 (Edition 1) and is listed in the ISO catalogue as published; users should verify the ISO catalogue for any more recent confirmations, amendments or replacements. As of the ISO catalogue entries used for this summary, the 2002 edition is the published edition. For the latest status always check the ISO catalogue or your national standards body.

Q: Is it part of a series?

A: Yes — ISO 15037 is a series of vehicle-dynamics test-methods parts. Part 1 addresses passenger cars, Part 2 addresses heavy vehicles and buses, and later parts (for example Part 3) address other test classes such as ride comfort. Consult the ISO 15037 series for scope of each part.

Q: What are the key keywords?
