ANSI ECA EIA-364-54A-1999 pdf download Magnetic Permeability Test Procedure For Electrical Connectors, Contacts, and Sockets
1 Introduction
1.1 Scope
This standard applies to electrical connectors, contacts and sockets.
1.2 Object
The object of this test is to detail a standard method to determine whether the magnetic permeability of a test item is below a specified value.
2 Test resources
2.1 Equipment
Permeability Indicator; Low-Mu: Severn Engineering Co., Permeability Indicator #3904, or equivalent.
3 Test specimen
3.1 Description
The test specimen shall consist of a fully assembled connector, connector components or contacts, as specified.
4 Test procedure
4.1 Unless otherwise specified, a 2.0 Mu pellet (insert) shall be used. The magnet of the hand-held indicator shall be alternately applied to and delicately removed from all the areas of the specimen.
4.2 Pulling the magnet from the calibrated pellet (insert) of the indicator shall constitute failure.
5 Detail to be specified
The following details shall be specified in the referencing document:
5.1 Number of specimens to be tested
5.2 Magnetic permeability value if other than 2.0 Mu
6 Test documentation
Documentation shall contain the details specified in clause 5, with any exceptions, and the following:
