Participation to interlaboratory comparisons

  • PT Pre-registration

    This section is dedicated to pre-registration for ILCs accessible through this procedure:

    1 - Participants interested in participating should pre-register. No invoicing is made for this pre-registration;
    2 - When at least 10 potential participants have pre-registered, CompaLab asks each of these pre-registered participants to confirm their willingness to participate and what are the characteristics for which they commit to provide results;
    3 - If at least 8 participants confirm their intention to participate, the ILC organisation concerned is committed.

    Your pre-registrations will reach us as soon as you have validated your order, without the need for payment. However, please note: if your basket also contains other ILCs, the corresponding registrations will only be validated once payment has been received.

    In all cases, you will receive an acknowledgement of receipt of your order by e-mail within a few days.
