A ferrous ball introduced into the falling product travels the same path a real fragment would, at the same speed, through the same part of the aperture — which is the only way to prove the detector and its reject flap respond in time. Ferrous balls are also used for in-pack validation, where the sphere is sealed inside a representative pack, and for periodic bulk-product checks in mills, spice plants and pet food lines.\u003c\/p\u003e\n\u003cp\u003eAlso available in \u003ca href=\"\/products\/non-ferrous-test-ball\"\u003eNon-Ferrous\u003c\/a\u003e, \u003ca href=\"\/products\/ss304-test-ball\"\u003eSS304\u003c\/a\u003e and \u003ca href=\"\/products\/ss316-test-ball\"\u003eSS316\u003c\/a\u003e as test balls, or as a \u003ca href=\"\/products\/ferrous-test-wand\"\u003eFerrous test wand\u003c\/a\u003e and a \u003ca href=\"\/products\/ferrous-flexible-test-wand\"\u003eFerrous flexible test wand\u003c\/a\u003e.
