This document describes the nature of the environmental effects, as well as test methods to evaluate, quantify and report (i.e. in specifications) the sensitivity of the frequency of standard frequency generators under environmental influences such as magnetic fields, atmospheric pressure, humidity, shock, vibration, acceleration, temperature, ionizing radiation, and intermittent operation.
