Introduction
The performance of the foot pad of the walking aid is very important to the safety of the user. When walking, the foot pads are continuously and repeatedly loaded and
Friction, so its durability is critical to safety and cost.
Foot pads are widely used in many walking aids, including walking sticks, crutches, walking frames, walkers and so on. According to the difference of the connected mobility aid
At the same time, the foot pads also come in different sizes, shapes and materials. There are many foot pads on the market that are suitable for the bottom shape of various specific walking aids.
Generally, rubber test pieces are used instead of rubber products when evaluating rubber durability. However, the foot pads of mobility aids are used in different ways
The same, therefore, testing with the finished foot pad will get more realistic data. For example, compared with other mobility aids, the burden of crutches
The load is higher, so the crutch foot pad needs better abrasion resistance.
The requirements and test methods for the durability of crutches foot pads listed in this document can be used by R&D personnel, manufacturers, distributors and nursing organizations.
Provide a basis for judging whether the foot pad has the necessary durability.
The purpose of GB/T 40889 is to specify the requirements and test methods for the related performance of the foot pads of mobility aids. Two parts are planned to be issued.
---Part 1.Friction of the foot pad. The purpose is to specify the requirements and testing of the friction between the foot pads of the mobility aid and the ground
method.
---Part 2.Durability of crutches foot pads. The purpose is to specify requirements and test methods for the durability of crutches foot pads.
