Full title and description
ISO 7141:2022 — Road vehicles — Light alloy wheels — Lateral impact test. This International Standard specifies a laboratory test procedure to evaluate the axial (lateral) kerb‑impact collision properties of wheels manufactured wholly or partly of light alloys, intended primarily for passenger‑car applications and for special vehicles where kerb impact is possible; it is used for screening and quality control of wheels.
Abstract
The standard defines the apparatus, specimen preparation, test conditions (impact energy and geometry), acceptance criteria and reporting requirements for a lateral (kerb) impact test on light‑alloy vehicle wheels. The objective is to provide a repeatable laboratory method to assess wheel damage and safety performance following a lateral impact.

Scope
Specifies a laboratory lateral (kerb) impact test method for light‑alloy wheels to evaluate their behaviour when struck laterally by a kerb. The scope covers test specimen preparation, mounting, impact energies and positions, acceptance criteria for damage/failure, measurement and documentation of results; it is intended as a screening and quality‑control test for passenger cars and special vehicles where kerb impact may occur.
Key topics and requirements
- Definition of test specimen (wheel) mounting and preconditioning requirements.
- Specification of impact apparatus, striker/kerb geometry and impact energy levels.
- Procedure for applying lateral impact and measuring resulting deformation, cracks or leakage.
- Acceptance criteria and pass/fail evaluation for wheel integrity and safety after impact.
- Reporting format and required test data to support traceability and reproducibility.
Typical use and users
Used by automotive OEMs, wheel manufacturers, independent testing laboratories and certification bodies for product development, type approval support, production quality control and comparative assessment of wheel designs. Engineers in R&D, safety and quality assurance use this standard to verify wheel resistance to lateral impacts and to define design/performance targets.
Related standards
Related documents include the previous edition ISO 7141:2005 (withdrawn and replaced by the 2022 edition) and other ISO/TC 22/SC 33 standards addressing wheels and rims, such as ISO 3911 (Wheels and rims — vocabulary, designation and marking). These related standards provide complementary requirements on marking, designation and other wheel tests.
