January 2022: CWEA revision

As Wallonia’s Reference Laboratory, ISSeP has just updated the CWEA (Compendium Wallon des méthodes d’Echantillonnage et d’Analyse): CWEA – Table of contents – ISSeP

In 2019, industry experts were consulted on the revised and new methods. Feedback has helped us improve our sampling and analysis methods.

On December 13, 2021, the French Minister for the Environment, Nature, Forestry, Rural Affairs and Animal Welfare approved a revision of the CWEA.

They come into force on January 20, 2022, with the exception of method S-III-2.2, which comes into force on July 20, 2022.
