Discussion on calibration method of non-combustibility test device of building materials

As the key equipment for grading and evaluating the non-combustibility performance of building materials, noncombustibility test device of building materials is widely used in construction industry for performance experiment and quality inspection of building materials. In order to prevent fire effectively, the requirements for the non-combustibility performance of building materials is higher and higher, hence more and more attention is paid to the noncombustibility performance test of building materials. In order to ensure the accuracy and reliability of the test results of non-combustibility test device of building materials, it is necessary to establish its metrological traceability system. However, till now, no national or local calibration specification for non-combustibility test device of building materials has been issued in China. This article presents a calibration method of “temperature indication error”, “furnace wall temperature” and “furnace temperature” for non-combustibility test device of building materials, and the feasibility has been proven by uncertainty analysis results.
