Flame arrester certification

Thread Content

The main certification types for flame arrestors used worldwide currently include UL certification in North America. UL certification is a type of certification related to safety assessment, originating from the Insurance Institute of America； FM certification; the M certification body is the only entity outside Europe that can directly issue the CE mark for fire protection products ； An officially recognized USCG certification; the USCG is responsible for safety in maritime traffic and transportation. The USCG certification certificates have an expiration date, usually five years ； The IECEx certification issued by the International Electrotechnical Commission refers to the certification for electrical equipment intended for use in industrial sectors such as petroleum, chemicals, coal mining, light textiles, food processing, and military industry, where there is a risk of accumulation of explosive gases, vapors, dusts, or fibers ； The CU-TR certification for countries such as Russia in the CIS is commonly referred to as EAC certification in the industry, as its certification mark is the EAC. Explosion-proof products exported to the Customs Union **(Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan) must obtain EAC certification. The EU ATEX certification originated from the directive on ‘Equipment and protective systems for use in potentially explosive atmospheres’ issued by the European Commission on March 23, 1994 – namely the well-known 94/9/EC directive. This directive specifies the technical requirements, as well as health and safety requirements, for equipment intended for use in potentially explosive environments. It also outlines the conformity assessment procedures that must be followed before such equipment can be brought onto the European market within its area of use. In other words, all equipment and protective systems intended for use in potentially explosive environments and exported to the EU must comply with the requirements of 94/9/EC directive; in other words, such products must obtain a certificate issued by the EU confirming compliance with this directive, namely the ATEX certificate. The term ATEX certificate comes from the abbreviation of the French term for explosive environments, Atmosphères EXplosibles. Above the ATEX certificate, the Ex mark shown in the figure below must be stamped. Regarding ATEX certification as well, the 94/9/EC directive issued in 1994 was replaced in 2014 by the new 2014/34/EU directive, with essentially no changes to its content. Are there any certified for China? I saw a post, but I couldn’t find anything related to China
