S-Risk offline for update


This morning, April 10, S-Risk version 1.2.2 will be released. For this reason, the S-Risk web application will be temporarily unavailable between 8 am and 12 am. Please communicate this further to all S-Risk users in your company, so this can be taken into account when planning S-Risk simulation work.

Updated FAQ entry


We have updated the following FAQ entry:

  • Why do mercury, copper, nickel, zinc and lead simulations sometimes give counterintuitive results?

Ordering Walloon S-Risk accounts


Ordering S-Risk accounts applicable to the Walloon region is now possible. More information about prices and how to order them can be found on our Registration page. Walloon accounts will be created and activated as soon as the official starting date of S-Risk in Wallonia is known.

User manual updated


The S-Risk user manual has been updated to reflect the latest changes introduced with S-Risk 1.2.1. You can find English and Dutch versions on our Documents page.

S-Risk updated to version 1.2.1


This morning, S-Risk has been updated to version 1.2.1. This release introduces a new, much-requested archiving feature, and a range of backend changes to enable the use of S-Risk in the Walloon region. A considerable number of generic S-Risk issues were fixed and improved as well.
More details can be found on our Release notes page.

As from December 12, 2016, the S-Risk licence and invoice system will be automated more. Therefore, the user agreement had to be revised and updated. The new version of this agreement can be found on our Registration page. Additional information will follow soon.
