Greenwood Magnetics is the UK market leader in magnet inspection and testing for the food industry, operating to BRC Global Standards for food safety.
With over 15 years of experience, we support food manufacturers in achieving and maintaining BRC certification.
Our on-site testing services are underpinned by comprehensive health and safety accreditations, including Safe Contractor and ISNetworld certification.
BRC Global Standards is a leading safety and quality certification programme, which guarantees the standardisation of quality, safety and operational criteria and ensures that manufacturers fulfil their legal obligations and provide protection for the end consumer.
BRC Global Standards are a fundamental requirement of leading retailers within the food industry.
Their latest guidance, Issue 9 of the BRC Global Standard For Food Safety, states in section 4.10
Foreign body detection and removal equipment should be used to reduce or eliminate the risk of contamination and, in section 4.10.4, that: The type, location and strength of magnets shall be fully documented. Documented procedures shall be in place for the inspection, cleaning, strength testing and integrity checks. Records of all checks shall be maintained.
To ensure BRC compliance, we offer magnet testing services to both new and existing customers. We provide full documentation which can be used together with existing HACCP procedures.
You will be provided with a full inspection report, including photographs detailing the type, location and strength of each magnet and whether it has passed or failed according to your process requirements. We will advise on the condition of the magnets and whether any action needs to be taken.
In addition, we will provide a copy of the gaussmeter’s calibration certificate for your records. The report also assesses the general state of the magnets and the housing and identifies where remedial action is required.

Magnets do not lose their strength if they are left in their natural state. However if they are exposed to excessive heat, vibration or shock, then they will lose some strength. For example, does the product flowing over the magnets sometimes exceed 80 degrees? Are the magnets are in a vibrating sieve or chute? Do the operatives bang the magnets when they clean them to remove excess product?
There is no specific frequency for magnet testing. It depends on the customer, what other protection is in the process (eg metal detectors) the level of contamination that may be present, and the production environment. As a general rule, most customers have their magnets checked annually.
