1. 1Use certified ferrous, non-ferrous and stainless steel test pieces of the specified size.
2. 2Place each test piece in or on a bottle in the normal product orientation.
3. 3Pass each one centrally through the aperture at normal line speed.
4. 4Confirm each is detected and physically rejected into the locked reject bin.
5. 5Record time, result and initials. Any failure: follow M-01.

Typical test pieces (actual sizes come from product validation): ferrous 0.5–1.0 mm, non-ferrous 0.8–1.2 mm, stainless steel 1.0–1.5 mm. Stainless steel is the hardest to detect.
