The qualification certificate for installation, maintenance, and repair of explosion-proof electrical equipment is one of the necessary qualifications for companies engaged in the explosion-proof electrical installation and construction industry. Many customers engaged in explosive industry installation and construction want to apply for such a certificate. As a specialized agency for handling explosion-proof electrical equipment installation, maintenance, and training qualifications, Zhongnuo Testing interprets the precautions for handling.

1. Issuing authority:There are currently three most common issuing institutions for this certificate, namely Shenyang Institute, Nanyang Institute, and Tianjin Institute.

2. Certificate Authority:The validity of the certificates from the above three institutions is the same and is recognized nationwide.

3. Handling entity:This certificate can only be processed in the name of the company, and cannot be processed by individuals or individual businesses. At the same time, there are requirements for the name and business scope of the processing company. Before processing, you can confirm with Zhongnuo Testing whether it can be processed and whether it is necessary to modify the business scope.

4. Employee certification issues:This certificate is held by at least three employees of the company together, and an additional fee will be charged for each additional employee. If an employee resigns, this certificate cannot be taken away. Generally, we recommend employees with long-term stability to participate.

Process:The customer only needs to provide the company's business license and the ID information of the employees, stamp and return the professional materials provided by Zhongnuo Testing, and participate in a 2-day training and exams during the training period. After the exam, simply send the test paper back to Zhongnuo for testing. All other matters will be handled by Zhongnuo Testing Agency. Easy and convenient to handle, worry free evidence collection!
