Is the inspection report for fire-resistant bridge trays required for each model?

The inspection report for fire-resistant bridge trays is not required for every model. The specific requirements depend on the actual application scenario and relevant standards. Generally speaking, for fire-resistant cable trays of the same material, process, and purpose, an inspection report can be issued. If there are significant differences between models, such as thickness, width, structure, etc., they need to be inspected separately and corresponding reports issued. In addition, according to relevant standards and regulations, the inspection items and requirements for fire-resistant cable trays in different application scenarios also vary, and specific problems need to be analyzed. It should be noted that fire-resistant cable trays are widely used in building electrical circuits, power distribution facilities, and power systems, and their quality and safety are directly related to personal and property safety. Therefore, it is necessary to choose appropriate institutions and standards during inspection and testing to ensure the accuracy and reliability of the test results. Meanwhile, during installation and use, it is also necessary to comply with relevant standards and regulations to ensure safety and reliability.
