Organization: NPFC
Publication Date: 6 August 1990
Status: active
Page Count: 125
scope:

This standard establishes requirements for methods of measuring and determining the magnetic characteristics (permeability; electrical conductivity; ferrous, stray and eddy current magnetic field strengths) of materials and equipment.

The requirements of this standard should be applied for the acquisition of materials and equipment to be used on nonmagnetic mine warfare ships and craft, as specified in the individual material and equipment specifications or in the contract.

Classification is applicable to the type of magnetic field source and the test method for tests established by this standard.

Magnetic field sources shall be classified as follows:

Class 1. Ferrous magnetic field.

Class 2. Eddy current magnetic field.

Class 3. Stray magnetic field.

Test methods are grouped in sections and designated by a series of numbers in accordance with the following system:

(a) Section 100 - Ferrous magnetic field tests are designated by "1XX".

(b) Section 200 - Eddy current magnetic field tests are designated by "2XX".

(c) Section 300 - Stray magnetic field tests are designated by "3XX".

(d) Section 400 - Electrical conductivity tests are designated by "4XX".

(e) Section 500 - Permeability tests are designated by "5XX".

(f) Section 600 - Final magnetic signature tests are designated by "6XX".

Where "XX" indicates the numerical order of tests from 01 to 99.

When a specific test method is required for measuring a magnetic characteristic of a material or equipment, the test methods contained herein should be referenced in the applicable document by specifying this standard and the test number.

intended Use:

This standard is to be used to ensure that the magnetic characteristics of materials and equipment are in accordance with the individual material or equipment specification, the contract or... View More
