Electrical Hazard (EH) safety shoes are primarily designed to prevent the formation of an electrical current path when the wearer comes into contact with high voltage. The soles are made of highly insulating materials capable of blocking current flow through the body at specific voltage levels, thereby reducing the risk of electric shock.<\/p>\n
<\/p>\n
\nThey primarily protect:
\nElectricians
\nPower utility maintenance personnel
\nPower transmission and distribution workers
\nConstruction electrical installers
\nIndustrial maintenance engineers<\/p>\n
<\/p>\n
Anti-static safety shoes are designed with the exact opposite objective: instead of blocking current, they facilitate the slow dissipation of static electricity accumulated on the human body into the ground. Static electricity is constantly generated while walking; if it is not dissipated in a timely manner, it can lead to the following issues in certain environments:
\nDamage to precision electronic components
\nIgnition of combustible gases
\nDust explosions
\nFailure of chemical products<\/p>\n
<\/p>\n
Therefore, anti-static shoes must possess appropriate conductive properties\u2014neither fully insulating nor excessively conductive.<\/p>\n
<\/p>\n
A. How are they tested under US standards?<\/p>\n
<\/p>\n
The American market primarily follows the ASTM F2413 standard. Key tests related to electrical properties include:<\/p>\n
\n1. EH (Electrical Hazard) test: The testing method involves placing the shoe on a designated test platform, filling the interior with a conductive medium, applying high voltage to the sole, and measuring leakage current.<\/p>\n
\nTypical test conditions:
\n18,000V AC
\nDuration: 1 minute
\nLeakage current must not exceed the specified limit.<\/p>\n
\n2. SD (Static Dissipative) test:<\/p>\n
\nThis primarily checks whether static electricity from the human body can be dissipated steadily. The resistance range is typically controlled between approximately 10\u2076 \u03a9 and 10\u2079 \u03a9; this ensures that neither a dangerous conductive path is created nor static electricity accumulates.<\/p>\n
<\/p>\n
\nB. How are they tested under European standards?<\/p>\n
<\/p>\n
European safety shoes primarily comply with EN ISO 20345, which covers two categories of electrical properties:<\/p>\n
\nAnti-static (A)<\/p>\n
\nTest content: Measuring the shoe’s electrical resistance.
\nRequirement: Resistance must fall within a specified range.
\nResistance must be neither too high (preventing static dissipation) nor too low (posing a risk of electric shock).<\/p>\n
\nTypical requirement: Approximately 100 k\u03a9 to 1000 M\u03a9 (10\u2075 to 10\u2079 \u03a9). Electrical Insulating Footwear: For high-voltage operations, Europe typically employs dedicated standards for insulating footwear (such as the EN 50321 series) rather than relying on the anti-static requirements found in the general EN ISO 20345 standard. These products are specifically designed and tested for electrical work.<\/p>\n
<\/p>\n
While both insulating safety footwear and anti-static safety footwear fall under the category of professional protective footwear, they address distinct safety needs. The former focuses on protecting personnel from the risk of electric shock, whereas the latter protects products, equipment, and the working environment by dissipating static electricity.<\/p>\n
