About CompaLab

CompaLab organises proficiency testing programs - also named PTP or interlaboratory comparisons or round robin tests - along ISO 13528 and ISO/IEC 17043 standards in order to evaluate the capacity of the participants to perform identified tests. The scope of these proficiency testing programs includes the tests on metals and metallurgy, particularly on steels, ferrous materials, copper alloys and coated steels (painted and galvanised steels). Any laboratory holding equipment and human resources necessary to perform these tests may participate, regardless of its legal status.

What is a proficiency testing program (PTP) ?

A proficiency testing program (PTP) or interlaboratory comparison (ILC) allows to evaluate the reliability of laboratories services, by sharing results of a same test, performed on a same product by all the participating laboratories. Furthermore, uncertainties on test results may be computed from results of these interlaboratory comparisons.

For more details, see What is an ILC
