Description of key information

According to REACH Annex XI, point 2, the guidance given in the test methods referred to in Article 13(3), more specifically on the technical limitations of a specific method, shall always be respected. The test guidelines relevant for biological degradation in surface water and/or water-sediment systems are OECD 308 and 309 (and their counterparts in EU Regulation 440/2008). The applicability of these test methods is explicitly restricted to organic chemicals. Therefore, as an inorganic compound, Hexagonal boron nitride falls outside the technical feasibility domain of biological degradation testing.
