Scope: This section gives the air pressure values of different seasides and the water pressure values of different water depths in addition to the natural environment, as the background material for selecting the appropriate air pressure or water pressure severity level when using the product. When determining the environmental conditions for product use, this section can be used as the background material for selecting the severity level of the product's air pressure parameters or water pressure parameters. The given value is also applicable in GB/T 4796-2001. The highest altitude of 30,000m takes into account the needs of meteorological observation units and air transport departments; the height of -400m corresponds to the deepest natural depression in the world.
