Test Procedure

1）The ignition source should be located at the entrance of the casing,And it is located on the inner side of the end plate that accommodates the device50mm,Observation results

2）When applicable, the test mixture should be in accordance with the standard15.4.3.1Preparation of regulations

3）During the experiment, the external surface temperature of the device should be monitored

4）Any device should be operated in accordance with the manufacturer's documentation. In5After each test, the explosive mixture should be kept outside the device for a sufficient period of time, at least10min,Allow continuous combustion on the surface of the device to a significant degree, causing an increase in temperature on the outer surface of the device or enabling temperature to be transmitted to the outer surface.

5）For each gas mixture of the specified gas category used in the device,The experiment should be conducted5Next time.
