5.4   Monitoring of Test Resources 

In the framework of quality assurance the measuring-related properties of the 
balance and, if applicable, the testing weight, must be checked regularly. The 
responsible user must define a suitable interval as well as type and scope of this test. 
Information is available on KERN’s home page (www.kern-sohn.com) with regard to 
the monitoring of balance test substances and the test weights required for this. In 
KERN’s accredited DKD calibration laboratory test weights and balances may be 
calibrated (return to the national standard) fast and at moderate cost.
