This module starts by covering the general concepts and principles of EU classification, before moving on to discuss the different classification processes and algorithms. You will learn how to classify substances using the ECHA inventory and how to classify substances and mixtures using data. Key content of this module is application of algorithms to classify mixtures. There are numerous worked examples throughout, allowing you to practice applying these different methods in a supported environment.
Correct substance and mixture classification is critical because classification informs and underpins many other CLP processes, such as labelling. For some, this module will be a challenge, but for all, it will be well worth the time!
