Abstract
The non-combustibility test furnace of building materials is the key equipment for grading and evaluating the flame retardant performance of building materials. It is widely used in the performance test and quality inspection of building materials. With the rapid development of economy and the acceleration of urbanization, urban construction is booming nowadays. In order to effectively prevent the occurrence of fire accidents, the requirements of flame retardant performance of building materials are higher and higher. In order to ensure the accuracy and reliability of the test results of the noncombustibility test furnace of building materials, it is necessary to evaluate the metrological traceability of the device. Therefore, basing on preparing the national calibration Specification Calibration Specification for Non-Combustible Test Device of Building Materials as well as by studying the related national and foreign standards, the author of this article has developed a set of calibration device for non-combustibility test furnace of building materials by analyzing the main metrological technical parameters of the furnace. The test results and application feedback have proved that the calibration device can dynamically calibrate the key metrological technical parameters of the furnace, such as temperature indication error, furnace wall temperature, furnace temperature, furnace temperature rise and furnace stabilization. The temperature measurement range of the calibration device for non-combustibility test furnace is (650 ~ 850)°C with the maximum permissive error of ±2.8°C.
