The First Domestic "Coefficient Shoes" Appearance Coefficient Refers To The Friction Coefficient.

The nominal "skid resistant" shoes on the market are not uncommon. However, by the identification of skid resistance, most of the static friction coefficients are not up to standard under the "three sessions of joint examination" of special testing instruments.

What is "static friction coefficient"?

According to the international inspection and identification of the nominal "skid resistant" shoes, it is necessary to distinguish dry, wet, oil and oil plus water types. The test environment of synchronous simulation must be divided into marble and tile floors, wet ground, oil stained ground and oil and water.

There are even strict rules on how much water should be simulated and how much oil should be touched in the test.

However, the majority of shoe manufacturers in China still do not have such an internationally recognized anti slip evaluation examiner, and there is no uniform "coefficient" testing standard.

It is reported that Shanghai Technical Quality Supervision Bureau has decided to introduce internationally accepted testing equipment, and the relevant unified national inspection and evaluation standards are also being intensified.

The obvious feature of the so-called "coefficient shoes" is that the above mentioned "static friction coefficient" is clearly marked on the shoebox, and the corresponding international coefficient standard is also provided. The purchaser can be clear at the same time, and it is also a quality commitment for the enterprise. If there is still an accident, it can also be used as a basis for testing and evaluating quality.

The first "coefficient shoes" unveiled on May Day were very high in the coefficient of insurance against slip. They all exceeded international standards. For example, the international standard of wet coefficient was 0.7, oil type was 0.35, while Shanghai's "coefficient shoes" were as high as 0.84 and 0.49 respectively.
