Description of key information

Flammability (diphenylsilanediol): not flammable

Key value for chemical safety assessment

non flammable

Additional information

The requirement to test the substance for pyrophoricity and flammability in contact with water was waived in accordance with Section 1 of REACH Annex XI, because there is no indication on the basis of structure and experience in use and handling that the substance is pyrophoric (flammable in contact with air) or flammable in contact with water.

The test substance was determined to be not flammable in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.

Justification for classification or non-classification

The substance is not classified for flammability as no ignition was observed during the study conducted in accordance with EU Method A.10.
