A set of test objects for adjusting the sensitivity of metal detectors "TSMO"

Technical description of the composition and design of a set of test objects The set of test objects must contain 12 metal test objects of different colors. Three test objects in the form of magnetic steel plates and nine test objects in the form of cylinders of magnetic (40ХНМА) and non-magnetic (12ХА18Н9Т) stainless steel. The test objects made of non-magnetic stainless steel are characterized by a circular groove or cut. The colors of the staining of the test objects correspond to the five security levels adopted in civil aviation. Safety level 1 (lowest) – blue test object made of magnetic steel, L-shaped, welded from two cylinders with a diameter of 25.4 mm and a length of 152.4 and 76.2 mm Safety level 2 – two green test objects – (one of magnetic steel and the other of non-magnetic steel), L-shaped, welded of two cylinders with a diameter of 25.4 mm and a length of 127 and 50.8 mm Safety level 3 – two yellow test objects – (one of magnetic steel and the other of non-magnetic steel), L-shaped, welded from two cylinders with a diameter of 25.4 mm and a length of 76.2 and 50.8 mm. Safety level 4 – three test objects in orange. Two test objects – (one of magnetic steel and the other of non-magnetic steel), L-shaped, welded from two cylinders with a diameter of 25.4 mm and a length of 50, 8 and 25.4 mm and the third test object – in the form 20 mm magnetic steel plates measuring 152.4 x 19 x 1.52 mm (simulated knife blade) Safety level 5 – Three red test objects. Two test objects – (one of magnetic steel and the other of non-magnetic steel), in the form of cylinders with a diameter and length of 25.4 mm, and the third test object – in the form of a plate of 20 magnetic steel, measuring 50.8 x 19 x 1, 52 mm (pocket knife blade simulator).
