Magnet Validations

Magnattack Global conducts annual and bi-yearly magnet checks on over 90 food manufacturing companies across Australia and also assists in metal fragment analysis and recommendations in other food related manufacturing sites around the world. Magnet validation and magnet strength checks are essential to maintain magnet efficiency over time and detect premature loss of magnet strength in critical areas.

Some “Rare Earth” magnets can lose strength quickly, especially some cheap imported units. Some may be only 6,000 gauss. Others of 10,000 gauss may have risky pole centres as far apart as 25mm, even 30mm along 25mm dia magnet bars. Therefore, periodic magnet checks using authentic gauss meters of current validity and correct magnet validation Gauss check procedures are essential to reducing risks of metal fragment contamination.

Magnattack Global carries out Magnet Validation Reports using currently calibrated instruments, using procedures and documentation internationally endorsed by recognised HACCP authorities.

Validation Reports and magnet strength checks establish:

• If the Magnet is as effective as it could be in its particular location
• If the Magnet is still as effective as it was at the installation date

Magnet validation Reports can also include:

• Recommendations to upgrade equipment to food safe standards
• Comparative analysis of metal contamination at critical control points

Magnet Validations should be carried out initially on supply, then annually, finally as dictated by history.

Magnet Validations and checks should normally be carried out using currently calibrated gauss meter equipment rather than dated and often inaccurate pull test methods. In addition to the magnet validation strength check service available from Magnattack Global, gauss meters are also available for hire or purchase.
