Certification body testing helps manufacturers produce high quality safety shoes

Safety shoes are the general name of safety shoes and protective shoes, which generally refer to the shoes worn in different workplaces to protect feet and legs from foreseeable injury. According to the function, safety shoes can be divided into toe protection safety shoes, anti puncture safety shoes, anti-static safety shoes, oil resistant safety shoes, anti-skid safety shoes, acid and alkali resistant safety shoes, high pressure resistant safety shoes, wear-resistant safety shoes, cold resistant safety shoes, waterproof safety shoes, etc

safety shoes are high-tech and high value-added footwear products, which play an important role in life safety protection. The requirements of raw materials and mechanical equipment are very high in the production process. For such products, if manufacturers want to sell their products to foreign markets, the test and certification work of authoritative third-party certification bodies is particularly important. The certification marks from these authoritative bodies can be said to be the reassurance of consumers

safety shoes test certification requirements

in design, the most important aspect of safety shoes is the protection function, including toe protection, anti puncture protection, anti electric shock protection, anti-static protection, metatarsal protection, electric saw protection, etc. At the same time, it should be noted that the safety shoes with anti puncture protection, metatarsal protection, electric saw protection and anti electric shock protection should have toe protection at the same time; And the anti-static protection or anti-skid protection function of safety shoes, can not take toe protection function< The following information should be permanently marked on the right foot of each pair of shoes: Manufacturer's name, trade name or applicant's CSA main contract number, production date (specific year / month or date code) and model the test object of safety shoes is brand-new safety shoes that have been produced for more than 14 days and stored at room temperature for 20 minutes before the test ± 2 ℃ and humidity 50 ± 5% of the environment for at least 40 hours, the test needs to cover the entire shoe size range. 1ndependent third-party testing and certification organizations, such as CSA international, will test the samples in many aspects, such as toe protection box materials need to ensure that the metal protection box will not be rusted, composite protection box needs to be tested by Fourier transform infrared spectroscopy, etc. the following briefly introduces the impact test, anti shock protection test and anti-static protection test impact test: need to take insole test test instrument: impact head weight 22.7k, diameter 25 ± 1t is 0.5mm cylindrical, and its length is more than 50mm and less than 75mm test requirements: impact energy of primary protection is 125 joules, impact speed is 3.32m/s impact energy of primary protection is 90 joules, impact speed i2.82m/s test steps: – take the rubber putty to make a cylinder with diameter of 25mm, cut according to the height of sample space, and place the rubber putty in the protection box according to the standard drawing – set the falling height of the impact head of the test instrument to obtain the impact energy of relative protection level and release the impact head – remove the dough and measure the remaining height test points: – at least half of the samples are stored in â€?18 ° ± two ° After c test – the samples should be stored at low temperature for at least 12 hours, and the impact test should be completed within 2 minutes after the samples are taken out from the refrigerator anti electric shock protection test: if the insole can be removed, it needs to be tested after removing the insole test requirements: the leakage current shall not exceed 1mA Test Method: – add a small steel ball (3mm in diameter) into the shoe, with a covering height of at least 30mm – pressurize at 1 kV / s from 0 to 18 kV for 1 minute anti static protection test: test instrument: the reading range is 0.1m-1000m Ω 1nsulation resistance meter of the transformer; 200 mm × 380 mm × 13 mm metal tray fixed at 380 mm × 380 mm, 460 mm × 460 mm wooden base test requirements: the insulation resistance value is between 1 and 100 megaohm test steps: – one wire of the megohmmeter is connected to the metal tray – add water into the metal tray, and the covering height is 3mm – small steel balls are placed in the sample shoes, and the covering height is 30mm – megaohm expresses another wire connecting the small steel ball in the sample shoe – a 50V DC power supply is used as the output, and 5mA is the maximum output current – the test results should be between 1-100 megohm certification of safety shoes in North America market taking North America market as an example, canadian standards applied to safety shoes are different from American standards, which are can / csa-z195 and ASTM f2413 respectively can / csa-z195 is the national standard for safety shoes in Canada. The protection types certified include toe protection, anti puncture protection of sole, anti electric shock protection, anti-static protection, etc CSA international can test and certify safety shoes according to can / CSA Z195 standard, and the products that pass the certification can use the authoritative certification mark in the United States, CSA international tests and certifies the performance and safety of safety shoes according to ASTM f2413. Similar to CSA Z195, the protection of this standard mainly involves toe protection, anti electric shock protection, anti-static protection, sole anti puncture protection, metatarsal protection, etc; 1n addition, ASTM f2413 also deals with another test of toe protection compression test CSA 1nternational’s ASTM certification mark appears on either shoe and is pasted on the inside or outside of the tongue of any shoe classification and signs of protection: one or more signs can be used on the tongue or outside of the right foot according to different types of protection of safety shoes. we solemnly declare that this article is reproduced by 1nternet media, only representing the author’s point of view, and has nothing to do with this website. 1f the information column articles and comments violate your legal rights, please call to let us know and we will deal with them in time
