Seven elements of safety shoes testing
- Nov 07, 2018 -


1. Testing the design of safety shoes

Upper height

Heel area

Sole structure


2. Detect the overall physical properties of safety shoes

Adhesion between the upper and the sole

Toe cap protection overall

Inner length of toe cap

Toe impact resistance

Toe cap compression resistance

Toe cap performance test:

1) metal toe cap anti-rust performance

2) non-metal toe caps in five environments

(acid, alkali, oil, low temperature, high temperature)

Impact resistance after treatment


3. Detect the physical properties of the safety shoe upper

Overall thickness of the upper

Tear strength

tensile strength 

Flexibility

Water vapor permeability and coefficient

PH value

Hydrolysis resistance

Hexavalent chromium content


4. Detect the inside of safety shoes

Tear strength

Wear resistance

Water vapor permeability and coefficient

PH value

Hexavalent chromium content


5. Detecting safety shoes, labor insurance shoes tongue

Tear strength

PH value

Hexavalent chromium content


6. Detect the sole of the safety shoes

Thickness

Tear strength

Wear resistance

Resistance to tortuosity

Hydrolysis resistance

Adhesion between composite substrates

Oil resistance


7. Detect the midsole and insole of safety shoes

Thickness

PH value

Water absorption and desorption

Wear resistant
