In January 1993, the ISO/TC94/SC3 Secretariat of the 3rd Professional Subcommittee of the 94th Technical Committee of the International Organization for Standardization (ISO) issued a draft ISO/CD 8782 four-part protective footwear standard to all member states. They are based on the European standards EN 344-1992, EN 345-1992, EN 346-1992, EN 347-1992. On December 15, 1998, the standard contents of the first, second, third and fourth parts of ISO 8782 were officially released. At this time, the EN standard has been revised from 4 to 8. Therefore, on March 1, 2000, ISO/TC94/SC3 released the fifth, sixth, seventh and eighth parts of ISO 8782. The technical content of ISO 8782 and EN corresponds to the technical content is completely consistent, but the international standards at this time do not require electrical insulation shoes.
In December 2000, the CEN/TC161 Secretariat, headed by the British Standards Institute (BSI), issued a new draft European Standard for Safety, Protective and Professional Shoes, in accordance with the Technical Cooperation Agreement between ISO and CEN (Vienna Agreement), International Standards. The draft is also issued with the same number. On August 1, 2004, the new international and European standards were officially released, namely EN ISO 20344, EN ISO 20345, EN ISO 20346, EN ISO 20347, which replaced the original ISO 8782 series of standards and the corresponding European standards. The new standard adds electrical insulation requirements and uses the requirements and test methods in EN 50321:1999.
In the United States, the ANSI Z41.2-1967 standard specifies the testing and requirements for foot protection shoes. In 1975, several standards for foot protection shoes were issued, including ANSI Z41.4 "Anti-shock injury shoes." Since then, the US standard has been revised and integrated into ANSI Z41-1999 in 1999. In 2005, it was revised to ASTM F2412:2005 "Foot Protection Test Standard" and ASTM F2413:2005 "Foot Protection Performance Specification" to prevent electric shock. The performance and testing methods of the shoes are covered.
It should be mentioned that another developed country, Canada, has adopted the US standard for its standard requirements and test methods for electrically insulated shoes, but it has its special features.
