For a long time, major industrialized countries in the world have each formulated mandatory national standards and technical requirements for explosion-proof electrical products based on their own national conditions in safety production regulations, and most of them cannot be mutually recognized. The practical difficulties brought about by the lack of mutual recognition of explosion-proof certificates are particularly prominent in the fields of ships and marine engineering, which have highly international division of labor and cooperation characteristics: explosion-proof electrical products must meet the requirements of different regulatory authorities, but these regulatory authorities or their authorized inspection agencies implement different standards.
The International Electrotechnical Commission (IEC) is a recognized organization that formulates international standards for electrical products and has established
IECQ： Quality assessment system for electronic components
IECEE： Electrical Product Qualification Testing and Certification Organization
IECEx： Explosion proof electrical product certification system
The main function of these three systems is to minimize the differences in product performance, safety, and testing requirements between different countries based on IEC standards, reduce or even eliminate unnecessary duplicate certifications and inspections between countries, and promote smooth international trade. Although explosion-proof standards in various countries are mainly formulated in accordance with IEC standards, the national standards developed by each country inevitably have certain differences with the constantly updated version numbers of IEC standards. This "time difference" is also one of the reasons for the existence of "national differences". Based on the above two factors, most member countries of the IECEx system still cannot directly accept itIECExauthenticationCertificate (CoC), the product also needs to go through the competent authority of the relevant countryExplosion proof certification.
