scope:

This standard covers the requirements for the design of d.c generators and motors (machines) that will minimize the stray magnetic field emanated by the generators and motors.

This standard applies specifically to the design of magnetic minesweeping generators since they generate large output currents and are used in minesweepers that will pass over magnetic-influence mines. Consequently, they must produce as small a stray magnetic field as possible, in order to minimize the danger of detonating a mine under the minesweeper. The requirements of this standard also apply to the design of any d.c. motor or generator for which a small stray magnetic field is an important consideration.

This standard shall be used in conjunction with the requirements of technical specifications and standards for a specific d.c. generator or motor. In the event that any design features of this standard (see 4.2.1 and 4.2.2) conflict with the requirements of other technical specifications and standards for the generator or motor, the design requirements of this standard shall apply.
