White Paper: Weighing in Legal Metrology - Use and Testing of Laboratory Balances in Legally Regulated Environments 

Legal metrology imposes strict requirements on weighing instruments, as the trueness and accuracy of their measurements is in the public interest. The legal obligation of verification serves to protect consumers and applies, among other things, to measurements in the areas of occupational safety and environmental protection as well as in medicine. 

The requirements set by legal metrology often do not meet the quality standards of a weighing application, especially in the case of highly accurate weighing of the smallest quantities on analytical and micro balances. This white paper describes the requirements and limits of legal metrology and identifies measures that help to ensure the quality requirements of weighing applications are reliably met.
