This section of GB/T 2423 gives a method for simulating the use of equipment-type samples that are severely moved or repaired during use.
Test method for impact effects caused by rough operation such as impact, vibration, and drop.
The impact of the simulated sample on the transport of the cargo as a loose constraint needs to be evaluated by the test Ee. bounce test method; the same

This test is not applicable to fragile, unprotected, irregularly shaped equipment (e.g. aircraft head radar), as these equipment are

This test is also applicable when it is on its own bracket or in a carrier and is considered as a whole.
For equipment with only one mounting surface (such as a standard bottom surface), tests are usually performed on that surface only.
The impact test is performed by fixing the sample on a test bench. Samples in dump and overturn, free fall, repeated free fall, and bounce tests
Products are made in a free state.

Summary	This standard specifies a test method used to simulate the impact effects of rough-type operations such as impact, vibration, and drop, which are mainly used when equipment samples are severely moved or repaired during use. The collision effect of the simulated sample in the transport of loosely constrained goods shall be evaluated by the test Ee: bounce test method; likewise, the impact effect of the simulated sample used to install the equipment shall be evaluated by the test Ea: impact. This test is generally only applicable to small and medium-sized equipment that may be subjected to severe handling, and only for angles and faces that are subject to the risk of knocking and impact. In general, equipment that is often moved and used (such as field equipment and spare parts) may be subject to the above-mentioned knocks and impacts. However, when they constitute a permanent device
