Nordtest Catalogue

nordtest-catalogue-2006-1The Nordtest Catalogue 2006 provides an overview of all test methods, technical reports, general documents and position papers published under the Nordtest umbrella before 2006. The reports and methods published after 2006 are not included in the catalogue. A new cataloque is under construction.

Handbook for environmental laboratories

forside537Update of 3rd edition
 A new version of third edition of the Handbook for Calculation of Measurement Uncertainty in Environmental Laboratories has now been launched - NT TR 537.

The free download can be done here.

 

This handbook is written for environmental testing laboratories in the Nordic countries, in order to give support to the implementation of the concept of measurement uncertainty for their routine measurements. The aim is to provide a practical, understandable and common way of measurement uncertainty calculations, mainly based on already existing quality control and validation data, according to the European accreditation guideline /12/, the Eurolab Technical Report No. 1 /3/ and the ISO/DTS 21748 Guide /8/. Nordtest has supported this project economically in order to promote and enhance harmonisationbetweenlaboratories on the Nordic market.

Practical examples, taken directly from the everyday world of environmental laboratories, are presented and explained. However, the approach is very general and should be applicable to most testing laboratories in the chemical field.

The handbook covers all steps in the analytical chain from the arrival of the sample in the laboratory until the data has been reported. It is important to notice that vital parts of the total measurement uncertainty are not included, e.g. sampling, sample transportation and possible gross errors during data storage/retrieval.

Software for measurement uncertainty calculation according to Nordtest TR 537:

The Finnish Environment Institute (SYKE) has published MUkit - measurement uncertainty software, which can be downloaded for free of charge from ENVICAL-SYKE website: www.environment.fi/syke/envical
