Interested in testing Chesar 3.5 beta version?

ECHA is currently finalising the development of Chesar 3.5, which is intended to be released in autumn 2019. The new version will include various improvements, including the possibility to create a substance directly in Chesar, calculation of MSafe for environment, and changes in the calculations of the TRA estimates when assessment entities exist, 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 approximately 2 weeks in the second half of September. If you would be interested in testing the beta version, please let us know by sending an email to chesar(AT)
