International Standard For Safety Shoes

Safety shoes are safety shoes.

1, European standard EN344:1997 "special safety, protection and work shoes".

The European standard is formulated by the CEN/TC61 Technical Committee of foot and leg protective products, and its secretariat is held by BSI.

This standard specifies the structure and performance indexes of safety protection shoes such as the design of the shoes, the whole shoe, the side, the shoe, the shoe tongue, the inner sole and the outsole.

The test methods specified in the standards are similar to those of other similar standards, and their principles are generally applicable to most safety shoes.

A. impact resistance of Baotou shall be subjected to impact test with steel weight impact hammer of specified weight. When Baotou is under impact, the clearance height below Baotou should be less than the specified value, and Baotou should not have any penetrating cracks in the direction of test axis.

It is worth noting that the standards of weight, specification, impact height and structure of the hammer are different in different countries.

The B. anti piercing performance test machine is equipped with a pressure plate, and the test board is equipped with a test nail. The test pin is a cutting head, and the hardness of the nail head should be greater than 60HRC.

The shoe sole sample is placed on the chassis of the test machine. The position allows the test pin to pierce through the outsole. The test pin penetrates the sole at 10mm/min + 3mm/min speed until the maximum force is recorded.

4 points on each sole are selected for testing (at least 1 points in the heel). The distance between the points is not less than 30mm, and the distance from the bottom edge is more than 10mm.

The bottom of the anti slide block should be punctured between blocks.

The 2 points in the 4 points should be tested within the distance 10-15mm from the edge line of the planting floor.

If humidity affects the result, the shoe sole should be immersed in the deionized water at 20 + 2 1H before the test. 16 +.

The electrical performance footwear of C. conductive shoes and antistatic shoes is adjusted in dry and wet atmosphere. The clean steel balls are filled into the shoes and placed on the metal probe device. The resistance between the front two probes and the third probes is measured by the specified resistance tester.

Under normal circumstances, conductive shoes require resistance should not be greater than l00K ohms; antistatic shoes require resistance between 100K ohms and 100M ohms.

D. thermal insulation performance of shoes as a sample, the thermocouple installed at the center of the bottom of the connection area, and the ball will be filled into the shoes.

Adjust the temperature of the sand bath to 150 degrees C 5 C, put the shoe on it, make the sand touch the sole of the shoe, use the temperature test device connected with the thermocouple, measure the temperature of the inner bottom and the corresponding time, and give the temperature increase curve.

The temperature increased from the sample placed to the sand bath after 30min is calculated.

The general insulation shoes require that the temperature increment of the inner surface is less than 22 degrees C.

The maximum compression load 6000N of the energy absorption test instrument for E. heel part is equipped with a device for recording load / deformation characteristics.

Put the heel shoe on a steel plate and place the test punch in the center of the heel part by the insole.

Load at the speed of 10mm/min 3mm/min.

The load / compression curve is drawn, and the absorbed energy E is calculated, expressed in Joule.

F. requirements for anti slip outsole, which stipulates the slip coefficient of the sole, but specifies the design and specification of the slider, such as the thickness of the sole, the height of the anti slider and the distance from the sole of the shoe.

3. Canadian working safety shoes standard

This standard is based on the Canadian Standard Association (CSA) standard according to Z195-02: "protective shoes" and Z195.1-02: "selection, care and use of protective footwear guide".

Range:

Possible injuries to the feet of workers may occur during the operation or in the working room of University of Toronto (Note: in this standard, "workers" include medical personnel, staff, international students and tourists).
