HN Metrology Consulting, Inc., based in Indianapolis, USA is a consulting firm founded by Danish metrologist expert Henrik Nielsen. On their web page, we find among other items two readable papers by Dr. Nielsen. The papers, which both contain information on the application of uncertainty budgets, were first presented to NCSL meetings in 1997 and 1998.

Per Bennich announces in this page that information and opinions on measurement uncertainty shall be made available. As of September 1999 we find information on Per Bennich's training course. There is also a nice paper on uncertainty. However, as of September 1999 it is available in Danish only. The ideas behind PUMA -methodology were developed by Per Bennich.
