Toe shoe

Protective toe shoes are safety shoes and protective shoes collectively, generally refers to wear in different work places have to protect the feet and legs from foreseeable injury to the footwear. Safety toe shoes are high-tech and high value-added footwear products, safety toe shoes production process on the raw materials, auxiliary materials, chemical materials, machinery and equipment requirements are high, many of the current have a certain size and The level of shoe-making enterprises have turned their attention to safety protection toe shoes in the past has been occupied by developed countries in the market. Xiaobian collected some of the international standards for the protection of toe shoes, I believe interested friends will like it.

1, the European standard EN344: 1997 "special safety, protective and work shoes"

This European standard was developed by CEN / TC 61 Technical Committee on Foot and Leg Protection and its secretariat is BSI.

The standard on the safety of toe shoes model design, the entire shoes, to help face, shoes, tongue, in the end, outsole and other structural and performance specifications. The standard test methods specified in various projects similar to other similar standards, the method principle is generally applicable to most safety protection toe shoes, the main indicators are:

a. Baotou impact resistance Specified weight of the steel impact hammer impact test Baotou Baotou under the impact of the gap height should be less than the specified value, Baotou in the direction of the test axis should not be any penetrating cracks. It is noteworthy that the national standards on the weight of the hammer, specifications, impact height and the structure of the test machine, etc. are different, the actual test should be distinguished.

b. anti-puncture performance testing machine is equipped with a platen, platen loaded with test nails, test nails for a truncated tip, nail head hardness should be greater than 60HRC. The soles of the sample on the chassis of the testing machine, the location of the nail can be pierced through the outsole, the test nail to pierce the soles 10mm / min ± 3mm / min speed until the penetration of the record required maximum force. Each shoe selected 4 points on the test (of which at least 1 point in the heel), each point no less than 30mm, and from the bottom edge of the distance greater than 10mm. There are anti-slide block at the end, should be pierced between blocks. Two of the four points should be tested at a distance of 10-15 mm from the edge where the plantar is located. If the humidity will have an impact on the results, soak the soles in deionized water at 20 ° C ± 2 ° C for 16 ± 1h before testing.

Electrical properties of conductive shoes and anti-static shoes Shoe samples After conditioning in a dry and humid atmosphere, a clean steel ball is filled into a human shoe and placed on a metal probe device using the specified resistance test apparatus to measure The resistance between the front two probes and the third one. Under normal circumstances, the conductive shoe resistance should not exceed l00K ohms; anti-static shoes require resistance should be between 100K ohms to 100M ohms.

d. Insulation performance To shoes as a sample, the thermocouple installed in the inner connecting area of the center, and the ball into the shoe. Adjust the temperature of the sand bath to 150 ° C ± 5 ° C and place the shoe on it so that the sand comes into contact with the outsole of the shoe and use the temperature test device connected to the thermocouple to determine the temperature of the insole and the corresponding time , Gives the temperature increase curve. Calculate the temperature increase from 30 minutes after placing the sample in the sand bath. General insulation shoes in the bottom surface of the temperature increase is less than 22 ℃

e. Energy absorption of the heel section The maximum compressive load of the test apparatus is 6000 N with a device for recording load / deformation characteristics. The shoe with the shoe placed on a steel plate, the test punch in the heel part of the inner center of the inner bottom. Load is applied at 10 mm / min ± 3 mm / min. Draw the load / compression curve and calculate the absorbed energy, E, in Joules.

f. requirements of non-slip outsole This standard specifies the test of non-slip coefficient of the sole, but the design of the anti-slip block, specifications and other provisions, such as the thickness of the sole, the height of the slider, with the edge of the soles are required.

2, the standard: EN345-1 US ANSI-Z41 China An1

Features: anti-smashing impact, puncture, anti-static, water repellent, non-slip oil, acid and alkali, high temperature, wear-resistant cushioning, sweat deodorant.

Upper: imported smooth leather, comfortable breathable, waterproof wear.

Inside: gray Stella + breathable cloth + absorbent cotton, disinfection and antibacterial, absorbent absorbent.

Insoles: Foam PU, anti-static, good rebound, compression resistance, breathable powerful deodorant function.

Sole: Two-color double density PU / TPU even help one injection molding, non-slip waterproof outsole can buffer pressure, comfort, non-slip, and super wear-resistant.

Steel head: Europe (CE) China An1 standard, can withstand 200 Joule impact (23KG * 900mm> 15mm) or to withstand 15KN static pressure.

3, Canada work toe shoe standards

This standard is based on the criteria of the Canadian Standards Association (CSA) as Z195-02: "Protecting toe shoes" and Z195.1-02: "Guidelines on selection, care, and use of protective toe shoes".


Workers may be injured in the foot during surgery or in the University of Toronto workplace. (Note: "Workers" in this standard include medical staff, staff, students and tourists).
