The metrology features of the balance and any possible available adjusting weight must be checked at regular intervals
within the scope of quality assurance. For this purpose, the answerable user must define a suitable interval as well as
the nature and scope of this check. Information is available on KERNs home page (
www.kern-sohn.com
) with regard to
the monitoring of balance test substances and the test weights required for this. Test weights and balances can be
adjusted quickly and at a reasonable price in KERNs accredited DKD calibration laboratory (return to national normal).
General:
According to the EU guideline 90/384/EEC balances must be verified officially if they are to be used as follows (legally

Verification information
An EU qualification approval is available for those balances marked as appropriate for verification in the technical data.
In the event that the balance is applied in an area subject to verification as described above, it must be officially verified
and re-verified at regular intervals.
Re-verification of a balance is carried out in compliance with the respective legal provisions of the states. The term of
