**REACH** is the European regulation on the **registration, evaluation and authorisation of chemical substances**. It governs the use of hazardous substances in products and requires, for some of them, that their presence be disclosed, the aim being to protect health and the environment.

## In the project

REACH concerns the project through the **materials and components** chosen: a component may contain a substance "of very high concern" whose presence has to be known. On the [[ecoconception-en|eco-design]] side, this can **steer a choice** towards an alternative. On the [[securite-et-qualite-en|safety and quality]] side, it is **recorded** as a constraint. In a teaching project, the constraint is cited and the course is pointed to. No full regulatory analysis is carried out.

*Regulatory expertise (substance lists, disclosure obligations, articles versus mixtures) belongs to the **standards course** and to the ESE discipline. This wiki limits itself to flagging what is at stake in the choice of components and materials.*
