Interested in testing Chesar 3.4 beta version?

ECHA is currently finalising the development of Chesar 3.4, which is intended to be released in autumn 2018. The new version will include various improvements for those using and developing use maps, as well as a number of changes to improve the user friendliness of the tool.

During the last development phase, we would like to invite Chesar users with some experience with the tool to help us test the beta version of the application. The testing period will last for 2-3 weeks in September. If you would be interested in testing the beta version, please let us know by sending an email to
