Proposed proficiency testing programs
| The 2019 ILC (interlaboratory comparisons) program includes chemical analyses of metals and ferroalloys, physical tests (metallography, decarburization and heat treatments, corrosion tests, determination of the roughness of a surface), tests on liquid paints and organic or inorganic coatings (viscosity, non volatile percentage and volumetric mass, thickness, gloss, colorimetry, cross-cut, pull-off test, aging tests), mechanical tests (Charpy impact test, Brinell, Rockwell and Vickers hardness tests, several types of tensile tests at ambient temperature or high temperature, bending test and rebend test, tube flattening test, fatigue test), tests of mechanics fracture, tests on welded joints, tests on bolts, tests on concrete steels and welded mesh shear test. | ||||||||||
| From 2019, in order to reduce the number of samples to be processed at the same time by participants, the year is divided into two series: | ||||||||||
| Series (see list of proposed ILCs) |
Opening date of registrations | Registration deadline | Date of shipment of samples | Start of the tests | Deadline for carrying out the tests and providing the results | Date of delivery of reports | ||||
| 1 | 15/12/2018 | 15/03/2019 | 20/05/2019 | 01/06/2019 | 15/07/2019 | 15/10/2019 | ||||
| 1 (long-term tests) | 15/12/2018 | 15/03/2019 | 20/05/2019 | 01/06/2019 | 31/10/2019 | 15/12/2019 | ||||
| 2 | 15/12/2018 | 30/06/2019 | 05/09/2019 | 15/09/2019 | 31/10/2019 | 15/12/2019 | ||||
| Note: After the deadline, registrations are only accepted within the limit of availability of samples | ||||||||||
| In addition to the assessment of the bias and repeatability, the participation to ILC organised by CompaLab provides an individual estimate the uncertainties of your test results. | ||||||||||
| At last, for participants who need their results very quickly, some samples which properties are known through the results of former ILC are also available. | ||||||||||
