Fire is one of the most common disasters in daily life. In order to reduce the harm caused by fire as much as possible, the fire resistance, fire resistance and the like of products in different application scenes are required correspondingly. Therefore, fire tests, etc. are one of the acceptable tests that most products must perform. In particular, the aircraft on-board equipment has very high requirements for fire resistance and fire resistance due to the special application environment.

At present, different airplane-mounted equipment can respectively carry out fire tests, fire tests and flammability tests according to the types of the airplane-mounted equipment and different materials, and the tests can be collectively called as combustion tests. For this purpose, corresponding test equipment and test methods are provided for carrying out the test testing of the device under test. The cable is a connecting device almost needed by various airplane onboard equipment, the test content possibly needed to be completed by different cables due to different airplane onboard equipment connected with the cables can be different, but in order to increase the universality of the cable, generally speaking, as many test items as possible are completed for the fire resistance test of the cable instead of a single test item, so that the cable can be adapted to the fire resistance requirements of various airplane onboard equipment. However, because the fire resistance tests are classified into very fine in the current aviation industry standards, the fire resistance tests and the flammability tests correspond to special test equipment and test methods, and comprehensive equipment capable of completing various tests is not available at present, particularly, the fire resistance and other combustion performance of a universal connecting device, namely a cable, are specially detected.

More importantly, in the existing equipment for performing the cable fire resistance test, the flame formed by the burner is performed in a fixed direction for the combustion of the cable, so that the real flame combustion condition in an airplane cannot be truly simulated, the test result is different from the real condition, the test result cannot accurately reflect the real condition, and the improvement indication of the test result to the cable is limited.

Disclosure of Invention
