Explosion proof certification is the process of determining that equipment meets the requirements of explosion proof standards, conducting type tests and routine tests, and issuing relevant certificates of conformity. Certificates can be used forExEquipment orExComponents.
Equipment and protective systems used in explosive gas environments must comply with multiple regulations, standards, and directives in order to enter the global trade market.
At present, there are roughly the following types of explosion-proof certifications worldwide:
The EU'sATEXCertification, adoptedENstandard
Used to standardize equipment and protection systems used in potentially explosive environmentsATEXExplosion proof directive2014/34/EUIt is a mandatory regulation among EU member states that hazardous areas or explosion-proof equipment intended for installation in the EU must comply withATEXinstructions 2014/34/EU.ATEXThe directive ensures the free flow of goods throughout the European Union through coordinated compliance procedures. Once the product has passed the instructions and obtained compliance certification, it can be affixedCELabeling andExLogo pattern.
The International Electrotechnical CommissionIECEXCertification, adoptedIECstandard
The purpose of IECEx certification is to establish an international certification system for explosion-proof products, to achieve unified standards, certificates, and marks in the audit of explosion-proof products, and to facilitate the rapid entry of compliant products into markets in various countries through a multi country certification mechanism, thereby promoting international trade. stay IECExsystemBelow, only accredited certification bodies are accepted（ExCB）And testing laboratory（ExTL）Engage in certification work for this system.
CIS region (Russia, Belarus, Kazakhstan, Kyrgyzstan)CU-TRCertification, adopted standards andIECsimilar
Customs Alliance Certification（Custom Union Technical Regulation Certificate）,Also known as Customs Alliance Technical Specification Certification, its certification mark isEACTherefore, the English abbreviation isCU-TRCertification orEACCertification. since2013 year 2 month 15 From now on, in order to obtain the authorization of the Customs Union (Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan) for the access of hazardous area products, it is necessary to obtainEAC(Eurasian compliance)ExCertification.EAC ExThe certificate indicates compliance with the technical regulations of the Customs UnionTP TC 012/2011Technical Specification Directive for Safety of Explosion proof Equipment.

China's explosion-proof certification adoptsGB3836national standards
According to the Standardization Law of the People's Republic of China, all explosion-proof standards are mandatory and must be enforced. Explosion proof products (including imports) used in China must be designated by the stateZhongnuo TestingExplosion proof inspection agency certification. Explosion proof inspection and certification agency in accordance with Chinese national standardsGB 3836Series, issued for the review and testing of explosion-proof performance of explosion-proof motors, explosion-proof electrical equipment, explosion-proof lamps, explosion-proof instruments and meters, explosion-proof communication equipment, explosion-proof transportation vehicles, and explosion-proof mechanical equipmentExplosion proof certificateBooks. Domestic coal safety certification not only adoptsGB3836In addition to the standards, China's unique industry standards for mining products are also adopted.
