SIEF interactions

SIEF interactions

The pre-SIEFs have been set up to establish substance sameness of compounds of the alloys and to reach agreement on classification and labelling. The Chromium Alloys Consortium is already engaged in discussions with the SIEFs relating to Chrome metal, Iron and Silicon and is also compiling the relevant compositional, physical, chemical and toxicity data.

In order to keep registration opportunities open at the time of pre-registration, all Members of the Chrome Alloys Consortium have pre-registered Ferrochromium and Ferrosilicochromium alloys under both the special preparation and the multi-constituent route:

  • For the pre-registration of alloys as a special preparation, the following substances have been pre-registered:

    Substance Name EC Number CAS Number Remarks
    iron 231-096-4 7439-89-6 As a component of FeCr and FeSiCr alloys.
    chromium 231-157-5 7440-47-3 As a component of FeCr and FeSiCr alloys.
    silicon 231-130-8 7440-21-3 As a component of FeSiCr alloys.
    carbon 231-153-3 7440-44-0 As a component of FeCr and FeSiCr alloys.
  • For the pre-registration of alloys as multi-constituent substance, the following substances have been pre-registered as “Reaction mass of” several substances, i.e. "Constituents":

    Substance Name EC Number CAS Number Remarks
    Reaction mass of:
    iron and chromium
        Ferrochromium alloy (FeCr), CAS 11114-46-8
    Constituents:
    iron 231-096-4 7439-89-6  
    Chromium 231-157-5 7440-47-3  
    Reaction mass of:
    iron and chromium and silicon
         
    Constituents:
    iron 231-096-4 7439-89-6  
    Chromium 231-157-5 7440-47-3  
    silicon 231-130-8 7440-21-3  

If you are within any of the pre-SIEFs for the substances represented by the Chromium Alloys, we would invite you to complete our surveys questionnaires accessed with your login and password (link to the SIEF Communication Tool, see the dedicated section in the following pages). The Chromium Alloys team will analyse the results of these surveys and will contact you to discuss further your registration needs and obligations.

If you have completed Chromium Alloys surveys and have any questions at this time, please contact us at . You may also contact us if you want to access, update or delete the information provided in surveys.
