The Technical Working Group of the "Si" Consortium has established an ID card for Silicon/FeSi silicate:
All companies that had pre-registered Silicon were contacted and asked to indicate if their substance fitted with the description in the proposed ID card. The enquiry was closed on 3 April 2009.
Companies that are of the opinion that their substance does not meet the criteria as described in the attached substance ID card are invited to demonstrate the sameness of their particular substance, if there is any doubt. When there is no doubt that their particular substance is NOT covered by the above definitions and the attached substance ID card, companies will have to form or to join a different SIEF.
Companies had pre-registered a substance for various reasons. In order to work effectively in the future SIEF, companies were invited to indicate what role they intended to play. That enquiry was closed on 3 April 2009.
