How many times is the emergency braking device test standardized in a year?

There is no fixed standard procedure for emergency braking device testing. This mainly depends on the specific usage scenarios and equipment requirements. ESD equipment should be tested regularly to ensure that they can work normally when needed. In some industries, such as chemical industry, petroleum, food processing, etc. ESD equipment needs to be tested daily or weekly. In some key equipment, such as nuclear reactor or aerospace equipment, it needs to be tested every hour or minute. For situations with high-risk or high-value equipment, it is necessary to test ESD equipment more frequently. For example, the crash landing system of aircraft and the life support system of medical equipment need to be tested once every second.
