Appearance quality cannot appear to help disabled, obvious flaws in baotou skew, etc.
And resistant to hit the security performance of the labor insurance shoes mainly from the compression resistance, impact resistance and corrosion resistance of baotou three aspects to detect, resistance to pressure testing is the rubber greasy cylinders placed in the top of the shoe, and then the shoes at a certain speed under the requirements of the corresponding force, continue to return zero after a minute, squeezed out of silly putty, related numerical value is measured with a caliper.
To prevent hit the impact resistance of Chinese shoes are put in baotou shoes head and cylindrical silly putty in impact machine, fixed toe cap, will impact hammer according to the requirements of the free fall test, then remove the silly putty with calipers measurement related numerical whether accord with a standard to ask.
Prevent hit a puff of labor insurance shoes due to moisture and feet sweat under the action of susceptible to corrosion effect, so in baotou must have the function of the resistance to corrosion, corrosion situation of baotou in the testing time will be processed on both sides of the baotou respectively, and the filter paper with filter paper, after a certain amount of time in baotou spots can't exceed five above, each spot area of no more than 5 mm.
Safety shoes after testing, the relevant numerical accord with a standard to be into the market, which is closely linked with our own safety.
