Uncertainty from sampling - A Nordtest Handbook (NT TR 604 ed 2)

NT TR 604 ed2

  • This handbook provides practical guidance on sampling uncertainty estimation in the Nordtest TR handbook format. The handbook is an extract of, and based on the principles, methods and text of the Eurachem Guide Estimation of measurement uncertainty arising from sampling. The Eurachem guide is more extensive and provides details on theory and additional examples. In 2019 Eurachem published a revised edition and therefore also the Nordtest handbook is revised.

    The overall purpose of this handbook is to provide a set of tools for calculation and control of the sampling uncertainty of the sampling procedure. It is the intention to make these tools and the understanding of their use available outside the world of analytical chemistry, although the basic principles applied originate from analytical chemistry. We hope that this is achieved but if not, please recall that statistics generally seem to be more complicated than it actually is…
