Safety shoe testing standards

The testing standards for safety shoes involve a number of aspects designed to ensure that safety shoes provide adequate protection for the wearer in a variety of work environments. Here are some of the main safety shoe testing standards and an overview of their content:

First, international testing standards

EN ISO 20345:

Overview: Safety footwear standards widely used in Europe and internationally are jointly developed by the European Committee for Standardization (CEN) and the Technical committee ISO/TC94.

Protection performance requirements:

Impact resistance: Safety shoes must be able to withstand at least 200 joules of impact energy.

Compression resistance: Safety shoes must be able to withstand a compression force of 15 kilontons (KN).

Puncture resistance: The middle soles of safety shoes need to have good resistance to penetration of sharp objects.

Anti-slip: In a wet or greasy working environment, safety shoes need to have good anti-slip performance.

Additional testing: including conductivity testing, antistatic testing, heat insulation testing, etc., to meet the special needs of different working environments.

Other international standards:

Such AS AS/NZS, DIN, JIS and other standard systems have also formulated corresponding safety shoe testing standards, which have legal effect in their respective countries or regions.

Second, domestic testing standards

GB 21148-2020 "Foot Protection Safety Shoes" :

Basic requirements: including the structure, material, comfort and other basic properties of shoes to ensure the basic performance of shoes in daily use.

Protection performance requirements:

Impact resistance: Test the impact resistance of the shoe head to ensure the protection effect of the inner head on the toe.

Puncture resistance: Evaluate the strength of the sole's puncture pad to prevent penetration by sharp objects.

Electrical insulation performance: Test whether the shoe can effectively isolate the current, suitable for electrical work environment.

Skid resistance: Evaluate skid resistance under different surface conditions through SRA, SRB or SRC tests.

Thermal insulation: Check the thermal insulation capacity of the sole and lining to prevent heat conduction damage.

Chemical protection: such as the detection of hexavalent chromium content of the shoe tongue to ensure that the material is harmless to the skin.

Other requirements include physical properties of the upper and outsole (e.g. tear strength, bonding strength, etc.), identification and marking, maintenance specifications, user information, etc.

Third, test items and methods

The inspection items of safety shoes usually include but are not limited to the following aspects:

Impact test: Use a simulated drop hammer test to test the resistance of the toe to impact.

Puncture test: Evaluate the strength of the sole's puncture pad to prevent penetration by sharp objects.

Anti-slip test: anti-slip performance test under different surface conditions (such as glazed tiles, stainless steel plates, etc.).

Electrical insulation test: Test whether the shoe can effectively isolate the current to ensure the safety of electrical operation.

Physical performance test: including the tear strength, binding strength, folding resistance of the upper and outsole.

Fourth, precautions

Standard update: Safety shoe inspection standards will be constantly updated with the development of time and technology, so in practical applications should pay attention to the latest version of the standard.

Applicability: Different industries and working environments may have different protective performance requirements for safety shoes, so the choice of safety shoes should be made according to actual needs.

Testing institutions: Qualified and experienced testing institutions should be selected for testing and certification of safety shoes to ensure the accuracy and reliability of test results.
