scope:

This standard covers the requirements that are imposed on materials and equipment which are to be installed on and that are pertinent to the magnetic silencing characteristics of nonmagnetic mine warfare ships and craft.

Adherence to this standard is required in the design of items, equipment, parts of equipment and systems which are to be installed on nonmagnetic mine warfare ships and craft. Adherence to this standard is also required in the development of installation practices for nonmagnetic mine warfare ships and craft. This standard is not mandatory in the design of items, equipment, parts of equipment and systems or in the development of installation practices for ships and craft with magnetic steel hulls.

Classification is applicable to the magnetic field sources upon which the requirements of this standard are imposed and types of magnetic information drawings.

Magnetic field sources are classified as follows:

Class 1. Ferrous field source.

Class 2. Eddy current field source.

Class 3. Stray field source.
