CE certification is limited to the basic safety requirements that the product does not endanger the safety of humans, animals and goods, rather than general quality requirements. The coordination directive only specifies the main requirements, and the general directive requirements are the standard tasks. Therefore, the precise meaning is: CE mark is a safety mark rather than a quality mark. It is the "main requirement" that forms the core of the European Directive.
Explosion-proof certification is the work used to determine that equipment meets the requirements of explosion-proof standards, type tests and routine tests for adaptation, and issue relevant certificates of conformity. Certificates can be for Ex equipment or Ex components.
Coal safety certification is the abbreviation of coal mine safety certification. In 2007, the State Economic and Trade Commission and the Coal Mine Safety Supervision Bureau issued documents such as the "Interim Measures for the Safety Signs of Coal Mine Products", which implemented a safety production certification system for underground coal mining equipment, instruments, meters and other facilities, effectively curbing the entry of counterfeit and shoddy products. downhole. The safety production marking system is an effective method. In order to improve the safety of coal mines, people pay more and more attention to the development of safety technology. The state has reformed the funding methods for technological development. Due to insufficient safety investment, the state should establish a financial guarantee mechanism for safety production research and development.
System certification means that an enterprise conducts a third-party evaluation of the enterprise’s management system or products through a third-party organization. The agency must be independent and impartial. [1]
The international standardization activities of system certification first started in the field of electronics. In 1906, the world’s earliest international standardization body, the International Electrotechnical Commission (IEC), was established. Work in other technical fields was previously undertaken by the International Federation of the National Standardizing Associations (ISA), founded in 1926, with an emphasis on mechanical engineering.
