Certificates of Calibration
This type of calibration is confined to the checking of the electronics of the metal detector
against the original specification, carrying out any adjustments or repairs as necessary. This is
normally carried out by the manufacturer against a written specification and using equipment
traceable to national and international standards. A certificate of calibration would then be
issued for the metal detector. Loma recommend this calibration should be done at least yearly.
Product Learn Process
This process is carried out by the user and involves passing the product through the metal
detector according to the requirements of the particular calibration system in use. This optimizes
the metal detector for the best performance.
Metal Test Pucks
It is recommended that all detector performance checking is conducted using Loma test pucks
which use metal spheres certified and traceable to national and international standards and
plastics which comply with the EU- Directive 2011/10/EC (Plastic Materials and Articles intended
to come into contact with food). Loma can supply upon request certificates of conformity for
test pucks supplied either with new equipment or as spare parts.
Please note that test pucks do not require annual calibration. However, the condition of the test
pucks must be inspected regularly for damage or deterioration such as cracks, corrosion, water
ingress, general wear and loss of markings that could affect hygiene and performance. It is
recommended that any suspect test pucks are destroyed and replaced.
Loma can supply a vast range of test puck types / sizes at-stock. Specials can also be made to
order. Please email teststicks@loma.com for further details.
Work Instructions, Training and Record Keeping
It is recommended that in line detector performance testing is covered by written instructions,
thus ensuring a clear and consistent approach by operators at all times and providing the means
to substantiate your methods to any assessment body who may ask.
It is recommended that all personnel who may conduct testing are suitably trained to do so and
records are kept to substantiate that training.
Accurate, easily retrievable records should be kept in a safe place for a defined period.
