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 requirents of OECD Guideline 110. The results are as follows: 
Proportion of test material having an inhalable particle size less than 100 µm: 93.1 %
Proportion of test material having a thoracic particle size less than 10.0 µm: <=0.313 %
Proportion of test material having a respirable particle size less than 5.5 µm: <=0.297 %
Please Note: The Nickel Sulphide representative sample was used to test this endpoint. Members of the Joint Submission could submit individual granulometry information in Section 1.4.
