The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Granulometry data has been acquired using a procedure designed to comply with the European Commission technical guidance document 'Particle Size Distribution, Fibre Length and Diameter Distribution' (June 1996), which satisfies the requirements of OECD Guideline 110. The results are as follows: 
Proportion of test material having an inhalable particle size less than 100 µm: 99.9 %.
Proportion of test material having a thoracic particle size less than 10.0 µm: 8.92 %
Proportion of test material having a respirable particle size less than 5.5 µm: 4.63 %
Please Note: The Nickel Dihydroxide representative sample was used to test this endpoint. Each member of the Joint Submission will submit individual granulometry information in Section 1.4.
