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. Using a sieve method, The three groups of Nickel Matte samples tested have the following proportions of test material having an inhalable particle size of less than 100 µm:
Nickel Matte (sulphidic low-copper): 0.1%
Nickel Matte (sulphidic high-copper): 1.5%
Nickel Matte (metallic): 0.3%
Please Note: The Nickel matte representative samples were used to test this endpoint. Each member of the Joint Submission may submit individual granulometry information in Section 1.4.
