Due to the unique field of use of explosion-proof equipment, its system form and related certificates are also greatly different from ordinary gourds. Below, Shanghai Yiying will provide you with a detailed explanation of the knowledge of explosion-proof equipment system form and related certificates.

　　Formal explosion-proof products require passing EC testing, and EC certificates are certificates of professional testing and test reports that comply with European directives. When purchasing explosion-proof electric hoists, customers should not forget to ask the seller for an explosion-proof certificate to ensure that the purchased electric hoists are safe and explosion-proof products. According to the different explosion-proof levels, the system principles vary, and are roughly divided into levels 1-5 explosion-proof, which are selected according to the operational requirements.

　　For products with explosion-proof systems, some explosion-proof forms require that the assembly components must also have explosion-proof characteristics. However, for products with isolated explosion-proof types, they basically use explosion-proof isolation shells to achieve explosion-proof effects, which can already isolate the ignition source from the outside. Therefore, this form of explosion-proof product does not require explosion-proof components, and explosion-proof electric hoists use isolated explosion-proof.

　　Regarding the explosion-proof certificate, an explosion-proof device must comply with European Community laws and require an ATEX certificate or EC test report certificate. International explosion-proof standards mainly include EN50014, 15, 17, etc. The more professional explosion-proof certificate is the ATEX certification certificate, which customers need to know before purchasing.
