Endpoint:
viscosity
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a solid
Conclusions:
In accordance with Section 2 of REACH Annex XI, information requirement section 7.17, this study cannot be conducted on solid materials or gases. According to ECHA Chapter 7 guidance, viscosity measurement is only relevant to liquids. The given test chemical is a solid powder compound. Hence this study can be considered for waiver.
