In the national anti-static safety shoes for the safety production of protective equipment, there are a total of 17 tests, but seven of the seventeen test items are not required for annual inspection or for shoes of certain fabrics. Detected. The remaining test items are only required to detect the shoe upper/outsole joint strength, upper tear strength, upper tensile performance, outsole thickness, outsole tear strength, outsole wear resistance, outsole folding resistance The performance of the sex and anti-static shoes, the energy absorption of the shoe area, and the identification of the ten items.
First, the anti-static safety shoes into the shoe upper / outsole bonding strength (except for all rubber, all-polymeric materials), in addition to the stitching bottom, the bonding strength ≥ 4.0N / mm.
Second, the tear strength of the upper (except for all rubber and all-polymeric materials) is 20 °C ± 2 °C at ambient temperature, relative humidity of 65% ± 5% leather and other fabrics should be ≥ 120N.
Third, the tensile properties of the upper are 20 ° C ± 2 ° C, the relative humidity of 65% ± 5% of the split leather tensile strength ≥ 15 N / mm 2 .
Fourth, the thickness of the outsole should be in addition to the area under the curling edge of the toe cap. The sole and the heel part should have a pattern that opens to the side. The thickness of the direct injection, vulcanization or adhesive outsole is d1≥4mm, and the height of the pattern is d2≥2.5. Mm
Fifth, the outer bottom tear strength (non-leather), in the ambient temperature of 23 ° C ± 2 ° C, the density of ≤ 0.9 g / cm 3 material requirements ≥ 5kN / m.
Sixth, the wear resistance of the outsole is non-leather density ≤0.9g/cm3 at an ambient temperature of 23 °C ± 2 °C, and the relative volume wear is ≤250 mm3.
Seventh, the outer bottom folding resistance is tested for folding resistance when the folding angle is lower than 45°, the outer sole is continuously flexed 30,000 times, and the incision growth is ≤4 mm.
Eighth, the electrical performance of anti-static shoes, when the ambient temperature is 23 °C ± 2 °C, in the dry environment (relative humidity 30% ± 5%) or humid environment (relative humidity 85% ± 5%) after adjustment 100kΩ ≤ resistance value ≤ 1000MΩ
Ninth, energy absorption in the shoe area ≥20J
Tenth, the requirements of the logo have a strong wear-resistant logo on the outsole/inner/face of each shoe (boot): manufacturer, product name, shoe (boot) number, implementation standard, production date/batch number The bottom of the shoes (boots) should have the words "anti-static", product manual, safety mark. This is the requirement for the national inspection of anti-static safety shoes.
