Air pressure : 86 kpa to 106 kpa (860 mbar to 1060 mbar) 3.2 Compass safe distance Severity and procedure IEC 60945:2002, Fourth edition, Clause 11.2, Compass safe distance. The compass safe distance is defined as the distance between the nearest point of the test specimen and the magnetometer, when the measured horizontal magnetic flux density is less than or equal to µt, corresponding to a compass deviation of 5.4 at a horizontal flux density of 1µT. For the steering compass, the standby compass and the emergency compass the permitted deviation is 18 /H. The corresponding magnetic flux density is less than µt. The compass safe distance of the test object was measured: a) In the magnetic condition in which it was received. b) After magnetisation in a DC field of 80 A/m, with a superimposed stabilising AC field of 1.43 ka/m and 50 Hz. c) In energised condition and normal operational mode. In each of the above conditions, the test specimen was rotated to determine the worst case direction.
