Previous Testing Proposals
This page provides the list of testing proposal consultations for which the deadline for comments has passed. ECHA addresses all third-party contributions in the dossier evaluation decisions addressed to the registrant.
To see if testing proposals submitted by registrants, and for which ECHA has held a third-party consultation, were subsequently withdrawn, please consult the table below. First, follow the link to the related aggregated registration dossier (if it is already published). There you can review the details of the testing proposed and other information on the substance that is subject to the testing proposal. The admissibility of any testing proposal will be concluded only after the third party consultation. Later during the testing proposal examination process, you may check the same section in the disseminated dossier to see if a testing proposal previously present has been withdrawn. The reasons for withdrawal may be that the registrant has reviewed their assessment or has taken into account the third-party comments provided to ECHA and communicated to them.
