Explosion proof certification is the process of determining whether equipment meets the requirements of explosion-proof standards, conducting type tests and routine tests for adaptation, and issuing relevant certificates of conformity. Certificates can be targeted towardsExEquipment 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, usingENstandard
Used to standardize equipment and protective systems used in potentially explosive environmentsATEXExplosion proof Directive2014/34/EUIt is a mandatory regulation among EU member states that hazardous locations or explosion-proof equipment intended for installation in the EU must comply withATEXinstructions 2014/34/EU.ATEXThe directive ensures the free circulation 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 design.
The International Electrotechnical Commission'sIECEXCertification, usingIECstandard
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 enable products that meet the standards to quickly enter the markets of various countries through a multi country certification mechanism, thereby promoting international trade. stay IECExsystemOnly accredited certification bodies are accepted（ExCB）And testing laboratory（ExTL）Engage in certification work for this system.

China's explosion-proof certification adoptsGB3836national standard
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 institutions shall comply with Chinese national standardsGB 3836Series, issued for the review and testing of explosion-proof performance of explosion-proof motors, explosion-proof electrical appliances, explosion-proof lighting fixtures, explosion-proof instruments and meters, explosion-proof communication equipment, explosion-proof transportation vehicles, and explosion-proof mechanical equipmentExplosion proof certificateBook. Domestic coal safety certification not only adoptsGB3836In addition to the standards, China's unique mining product industry standards have also been adopted.
