EVS-EN 13319:2000

This standard specifies functional and safety requirements for depth gauges, depth gauge features of other instruments, and both depth and time measurement features of other instruments. It is not applicable to any information displayed to the user besides depth and time. Any information on decompression obligations displayed by equipment covered by this standard is explicitly excluded from its scope. This standard is applicable to instruments measuring water depth by the environmental pressure as used by divers. Requirements for time measurement are only applicable if instruments are automatically counting the diving time.
