SNB’s Tips and Advice When Selecting Test Pieces

Most manufacturers have Codes of Practices to work towards. Make sure to check your Codes of Practices as it should advise sensitivities that need to be achieved on your metal detector.

Test pieces can be supplied in different formats to suit the type of metal detector on site. SNB can supply test balls to go through vertical drop metal detectors, test sticks for conveyor metal detectors and other pieces such as cards, pucks and pipeline sticks.

If you require further advice on which test piece size or type to purchase, then you can contact SNB on 01977689555.

How Often Should A Metal Detector Be Tested?

Metal Detectors should be tested at regular intervals. The retailer recommends once every hour with your test pieces, some even recommend every half an hour. This is because if you test your metal detector at 9am and it passes, but at the 9.30am tests it fails, all the product within that half an hour window would need retesting. When conducting these tests, you should pass a test stick with ferrous, non-ferrous and stainless steel spheres.

To conduct thoroughly, your test pieces should be placed on or in your product so they go through the centre of the aperture. It is required that test sticks travel through the centre of the aperture as this is the weakest point of the metal detector. Testing in the centre will confirm that your test pieces are detectable in all positions.

Top Tip – make sure to test all three test stick types as in some cases your metal detector to confirm full spectrum of detectability.
