1 Scope

This section GB/T 18029 specifies the rough test plane (if not polished concrete surface) of the friction coefficient measuring methods. Such as If the method specified in this section for testing smooth or polished surface, the measured coefficient of friction over the entire test plane should be a constant value.

The wheelchair several test items (such as GB/T 18029.1, GB/T 18029.3, ISO 7176-2, ISO 7176-6 and ISO 7176-10) requires the surface coefficient of friction in the range specified in this section.

3 Terms and Definitions

GB/T 14729 terms and definitions given in the following terms and definitions apply to this section.

Pavement, flooring, wheelchair support surface or testing platform.

Principle 4

The coefficient of friction between the wheelchair and the wheelchair depends on the test plane of the tire and the test plane. In order to have a comparable level test Test results compare different stage of wheelchairs, this part of the determination of the coefficient of friction using standard defines the test surface, this process with the measured wheel Chair car unrelated.

This method is tested on a test surface of the block at a predetermined speed to pull a standard rubber in contact with the surface.
