1. European standard: European Common Market Safety Standard (EN344.1: 1992) According to the testing methods and specifications of this standard, safety shoes can be divided into three types:
A, EN345.1: 1992: Safety shoes for professional use, built-in steel sheet in the toe, can prevent the impact force equal to 200 J (J).
B, EN346.1: 1992: Professional-purpose protective shoes, built-in steel sheet in the toe, can prevent the impact force equal to 100 J (J).
C, EN 347.1: 1992: professional use work shoes, there is no steel sheet in the toe.
2. American Standard: American Standard (ANSI-Z41-1991) According to the resistance of shoes to compression and impact, safety shoes with protective toe can be divided into three types.
3. Australian Standard: Australian Standard (AS/NZS 2210.1: 1994) This standard divides safety shoes into 4 types.
4. National Standard: National Standard of the People's Republic of China. G.B.4014-83 Leather Safety Shoes. G.B.7054-86 Rubber Surface Safety Boots
5. Japanese standard: Japanese standard (J1S-T-8015: 1983)
First, European Standard EN 344:1997 "Special Safety, Protection and Work Shoes" This European Standard was developed by CEN/TC61 "Protective Products for Foot and Leg Protection" and its secretariat is operated by BSI.

Факт Проверка Должна Должна Различать.
The test machine is equipped with a pressure plate on which the test nail is mounted. The test nail is a tip with a cut-off tip, and the hardness of the nail head should be greater than 60HRC. The sole sample is placed on the chassis of the testing machine in such a position that the test nail can be pierced through the outsole, and the test nail pierces the sole at a speed of 10 mm/min ± 3 mm/min until the penetration is completed. The greatest strength. Four points are selected on each sole for testing (at least one of which is at the heel), each point is not less than 30 mm apart, and the distance from the insole edge is greater than 10 mm. The bottom of the anti-slip block should be pierced between the blocks. Two of the four points should be tested within 10-15 mm of the edge line of the bottom of the plant. If humidity affects the results, the sole should be immersed in deionized water at 20 degree ± 2 degree for 16 ± 1 h before testing.
c. Electrical properties of conductive shoes and anti-static shoes
After the shoe sample is adjusted in a dry and wet atmosphere, the clean steel ball is filled into the human shoe and placed on the metal probe device, and the first two probes and the third probe are measured using a prescribed resistance tester. Resistance between. Under normal circumstances, conductive shoes require resistance should not be greater than l00K ohms; anti-static shoes require resistance should be between 100K ohms and 100M ohms.
Использование башмак как а образец, термопара есть размещено в на центр стелька соединение площадь, и сталь шарик есть наполненный в башмак. отрегулировать температура из песок ванна до 150 градус C ± 5 градус C, положить the shoe on it, make the sand contact the outsault of the shoe, use the temperature test device connected with the thermocouple to measure the temperature to temperature to thermocouple to measure the temperature из стелька и соответствующее время %2с дает температура увеличение кривая. температура повышение от 30 минут после образец был помещенный на на песок ванна был рассчитанный. В целом утепленный обувь требование повышение в температура из в внутренняя подошва поверхность из меньше чем 22 градус .
The test instrument has a maximum compression load of 6000 N and is equipped with a device for recording load/deformation characteristics. The shoe with the heel is placed on a steel plate, and the test punch is placed on the inner side of the heel portion against the insole. The load was applied at a speed of 10 mm/min ± 3 mm/min. The load/compression curve is plotted and the absorbed energy E is calculated, expressed in joules.
f. Requirements for non-slip outsole
This standard stipulates the anti-slip coefficient of the sole, but specifies the design and specifications of the anti-slip block, such as the thickness of the sole, the height of the non-slip block, and the distance from the edge of the sole.
Second, the standard: EN345-1 US ANSI-Z41 China An1
Function: anti-mite anti-impact, anti-puncture, anti-static, anti-splash, anti-skid, oil-resistant, acid and alkali resistant, high temperature resistant, wear-resistant cushioning, sweat absorption and deodorization
Inside: Gray Stella + moisture permeable cloth + absorbent cotton, disinfection and antibacterial, absorb and absorb sweat
Shoe pad: foamed PU, anti-static, good rebound, compression resistance, breathable strength and deodorization
Sole: Two-color double-density PU/TPU with integrated injection molding, non-slip waterproof outsole can cushion pressure, comfort, anti-slip, and super wear-resistant
Steel head: European (CE) China An1 standard, able to withstand 200 Joule impact force (23KG*900mm>15mm) or withstand static pressure of 15KN
This standard is based on the Canadian Standards Association (CSA) standard according to Z195-02: "Protective Shoes" and Z195.1-02: "Guidelines for Selection, Care, and Use of Protective Shoes."
Scope: Работники могут могут быть подвергаются к возможно травмы во время операция или в Университет из Торонто's рабочее место (Примечание: В это стандарт, "работники" include медицинские персонал, персонал, международные студенты, и посетители).
