Test Pieces for Metal Detection

Routine validation and performance testing of industrial metal detection and X-ray inspection equipment is a key requirement to meet with codes of practice, quality management systems and associations such as HACCP, BRC, IFS, ISO9000.

We stock and supply a wide range of test pieces for Ferrous, Non-Ferrous, Stainless Steel 316, Glass and Ceramic, colour-coded for easy visual identification complete with Certificate of Conformity.

Typical sizes available: 1.0mm up to 8.0mm and 20.0mm, with specific sizes availability on request, in Stick, Flexible Wand, Ball, Block or Card form. All are FDA approved, made from food grade Shatter and Chip resistant Polymer material. Test piece sizes are typically determined by your customer, a code of practice or based on your own internal critical control points (CCP) process following sensitivity testing on your equipment and specific product. Many factors can affect the desired size including product size & effect (wet/dry etc.), detector aperture size and sensitivity.
