Register to participate to an ILC


General conditions to participate

Taking part to ILC involves the acceptance of the general conditions for participation (see the general conditions for participating).

The test results of a same participation must be obtained “under conditions of repeatability” as defined in ISO 5725-1 (same operator, same test equipment, same environmental conditions, performance of all tests at the same time). The laboratories that registered for several participations to a same ILC must get their results “under conditions of reproducibility” as defined in ISO 5725-1 (different operators, different test equipments, different environmental conditions, performance of tests at different moments). However, for test for which several performances of testing are possible on a same sample (chemical analysis, metallography, physical characteristics of paint coatings, roughness), up to 8 determinations may be achieved in in between conditions. The statistical processing takes this particular issue into account.  Please consider this issue when deciding the number of your participations.


The prices for participation include:

  • A fee to participate to one ILC,
  • Transportation fees, for the ILC related to the weight of the samples and the location of sending the samples,
  • A discount, when the customer takes orders the participation to several ILC*.

* :    A discount is given for participations of a same registration of several laboratories or/and of one laboratory to several ILC, as detailed in the price list.

The price list is available here: Price list
