Measurement uncertainty arising from sampling

NTTR604ed2FrontNT TR 604 Uncertainty from sampling - A Nordtest Handbook has been revised in scope of the updated Eurochem Guide. Nordtest has a valuable longterm ongoing cooperation with Eurachem.

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. EurachemIt 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…

The history of Nordtest

Nordtest - a brand for conformity assessment

Nordtest was originally founded in 1973 under the Nordic Council of Ministers and has since then acted a a joint Nordic body in the field of conformity assessment. The 1st of January 2004 it was merged with the Nordic Industriel Fund into the Nordic Innovation Centre, based in Oslo. 

In all history the emphasis has been on development of Nordic test methods and on Nordic co-operation concerning conformity assessment - approved once -> accepted everywhere. No barriers for products and services within the Nordic countries.

During the years about 1500 methods ( 600 is still running) and more than 600 technical reports have been published.

New national standard in Nordic countries

BUILD515 front 2A cooperation among road authorities in Finland, Norway and Sweden has created a new Nordtest method NT BUILD 515 for hydrophobic impregnation of concrete. The road authorities of the Nordic countries allocate, yearly, vast sums on the hydrophobic surface protection of reinforced concrete structures (e.g. bridges) in order to reduce the risk for chloride induced corrosion, caused by the extensive use of de-icing salts during harsh winters or sea water ingress.
