Fire-resistant bus ducts are widely used in various fields, such as building construction, industry, and rail transportation. These bus ducts are designed to maintain the integrity of electrical circuits within a specific time frame during a fire, meeting the requirement for continuous power supply during emergencies. Recognizing the complex application environments of these products, CQC has taken measures to enhance the effectiveness of certification testing.To ensure the validity of certification testing results, CQC has implemented on-site witnessing of certification personnel in the laboratory during the testing process. Only products that have been evaluated and found to meet the requirements for fire resistance performance are eligible to receive the Emergency Products Certification from CQC, along with the application of the CQC Certification Mark for Emergency Products.

As a national-level quality service organization, CQC always adheres to the essential nature of quality certification as "delivering trust and serving development."
