Test Method for Magnetic Dangerous Goods
1 Scope
This standard specifies the terms and definitions of dangerous goods magnetic testing, test equipment, test procedures and test reports.
This standard applies to dangerous substances Test magnetic field strength.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
ICAO/IATA "Dangerous Goods Regulations"
3 Terms and Definitions
ICAO/IATA "Dangerous Goods Regulations" and established the following terms and definitions apply to this standard.
3.1
At any magnetic medium, the ratio of magnetic field magnetic induction B at a point with the same point of the magnetic permeability μ is called the magnetic field strength at this point
H, namely. H = B/μ, in units of A/m (A/m).
3.2
Any substance at any point at a distance of 2.1m of its air transport package surface, the measured magnetic field strength greater than or equal to 0.159A/m.
4 Test Equipment
Oster table, Michi, a magnetic compass.
5 test procedure
Oster Table 5.1 Assay
Oster on the table apart point 4.6m away two points, the position should not interfere with the Earth's magnetic field. The first table Oster
Two points in a line and adjust the table of zero, two magnetic objects on another point, the rotation of the magnetic body in a horizontal position on the package, measuring
Location given magnetic field strength.
5.2 Determination of the magnetic compass
Magnetic compass placed on a little distance 4.6m away two points, and to what direction the Earth line, should be free from the Earth's magnetic
Field interference. The magnetic objects to another point on the package, the package rotating magnetic objects in a horizontal position, the test instrument bias.
Table 5.3 Oe magnetic compass united determination
The magnetic field strength was measured in accordance with 5.1 and 5.2 of the method.
5.4 Test Results Recording
--- Oster table method shall be recorded maximum magnetic field strength test sample tested is less than or equal to 0.418A/m;
--- Magnetic compass method shall be recorded in a test sample using a compass Maximum deviation is less than 2 °;
--- Table Oster magnetic compass united determination shall be recorded in the test sample distance field strength is less than 2.1m
0.159A/m, magnetic compass whether the apparent shift (offset less than 0.5 °).
