Loma systems rationalises test pieces

14 August 2016

Loma Systems has rationalised its range of ferrous, brass non-ferrous and stainless steel test pieces in a strategic move designed to ensure high performance operation of its advanced metal detection and X-ray inspection equipment, while adhering to increasingly stringent quality protocols, such as ISO 9000, HACCP and retailers’ Codes of Practice. 

The company has rationalised and updated its range of test pieces with the intention of further improving quality and finishes. As part of this initiative it has standardised on test pieces produced from 316 grade annealed stainless steel as specified by major retailers’ Codes of Practice, resulting in the eventual discontinuation of grade 304 stainless steel pieces.
In a bid to help food plants keep better track of their test pieces, Loma is also set to replace ferrous, non-ferrous (brass) and stainless steel test wands with a new puck design. It has also colour coded and improved the quality and finish of its vertical fall drop balls, pharmaceutical tablets and flex wands to meet Codes of Practice requirements for full traceability and certification.
Simon Spencer, managing director at Loma Systems said: “Performance testing of metal detectors and X-ray inspection systems is an essential part of quality management. In fact, food industry regulations stipulate systems are installed at critical control points and routinely QA tested with documented results. 
“We are aware that many food manufacturers, processors and packers have written their test procedures based on the use of grade 304 stainless steel and changing to 316 test pucks might cause extra work. However, we made these changes to ensure compliance with major retailers’ Codes of Practice which specify grade 316 as the best material for test pieces.
“In making the switch to grade 316, we conducted several like for like comparison tests against grade 304. The results demonstrated that the new format is generally more difficult to identify which offers greater reliability for the detection of grade 304 stainless steel.
