AUDIBLE WARNINGS. A conveyor may be fitted with an alarm which operates when a
nonconforming product is detected. The maximum volume of the alarm is type
dependent and lies in the range of 110 dB (A) to 125 dB (A) at 1 metre.
4.
VISUAL INDICATIONS. The system may optionally be fitted with indicator lamps which
operate to show a particular status or in the event of a fault condition. The X-Ray
Inspection Systems must not be operated unless all such indicators are fully
operational. There are also more detailed fault listings displayed on the operator
screen.
5.
RADIATION LEVELS. Each Loma x-Ray inspection system has a radiation survey to
ensure that the radiation levels emitted from the system are within the specified
allowable limits. The legislative figure in the United Kingdom is 1μSv/h, but a typical
Loma system achieves 0.3μSv/h on average. In addition, when a system is
commissioned on a customer's premises, a critical examination / radiation survey is
carried out and the results stored on record at Loma. A copy is also provided to the
customer.
Quality Assurance
By your selection of a Loma X
5c
X-Ray Inspection System you have demonstrated your
intention to assure the quality of your products, and thereby protect your customers.
The following points are recommended:-
Once your Loma X
5c
X-Ray Inspection System is installed you should contact your
local Loma Service Department to have it commissioned.
Regularly test the operation of the X-Ray Inspection System to monitor its
performance. Keep accurate records of those tests and any samples being used
along with the product details.
If the X-Ray Inspection System fails a test, quarantine the products passed through the
system from the last successful test and re-introduce them through the system once
the system is fit for use.
Have the X-Ray Inspection System supported by a Planned Preventative
Maintenance Contract. Details can be obtained from your local Loma Service
Department.
If you have or intend to have BS EN 9000 accreditation, write a section into your
Operating Procedures Manual covering the operation and maintenance of the X-
Ray Inspection System and carry out regular calibration of the machine to ensure its
accuracy.
Finally, at least on a yearly basis and when any changes or additions have been
made, have your operators, QA and maintenance personnel trained in the use of the
X-Ray Inspection System. Details of available training can be obtained from your local
Loma Service Department or by sending an email to
