What is ISO 13988 about?
ISO 13988 specifies procedures and minimum performance requirements for testing without tyres the retention of balance weights for use on wheels for passenger vehicles.
ISO 13988 also specifies general features for configurations of clip balance weights, rim flanges for light alloy and steel wheels intended for use on passenger cars and adhesive balance weights. Alternative materials and geometries can be considered in the future.
Who is ISO 13988 for?
ISO 13988 on passenger car and light truck vehicle wheels is useful for:
- Vehicle regulatory authorities
- Vehicle repair shops
- Manufacturer of passenger car and truck
- Car and truck Mechanic
- Manufacturer/supplier of wheels
Why should you use ISO 13988?
Clip balance weight assembly is intended for mounting on the rim flange to balance the tyre/wheel assembly about its axis of rotation and thus minimize vibrations due to the rotation of the tyre/wheel assembly.
ISO 13988 provides general features and configurations of the clip balance weights, general features of the adhesive balance weights, and general features and configurations for rim dimensions relevant to clip on weights and defines terms used to describe these features which will help you to properly assemble clip and adhesive balance weights on passenger car wheels to minimize vibrations.
ISO 13988 provides test procedures for testing without tyres the retention of balance weights for use on wheels for passenger vehicles that help you to evaluate weight retention on the wheel.
What’s changed since the last update?
BS ISO 13988:2021 supersedes BS ISO 13988:2008, which is withdrawn
This second edition replaces the first edition (ISO 13988:2008), which has been technically revised. The main changes compared with the previous edition are as follows:
- Adhesive balance weights have been added, which covers clip-on weights only
- Nomenclature for the balance weight and test procedures and performance requirements for the adhesive weights have been included
