Participation in proficiency testing schemes is a useful tool for testing laboratories to achieve different objectives, such as assessing personnel skills, analysing the differences between testing methods, assigning values to reference materials and, of course, demonstrating the consistency of the data produced through said tests.
It is essential for clients to have the confidence that the testing laboratory can systematically produce reliable results and, therefore, accreditation bodies require the regular and satisfactory participation of testing laboratories in proficiency testing schemes. To this respect, the ISO/IEC standard 17025 establishes a requirement, whereby laboratories can only be accredited if they take part in proficiency testing schemes, provided there are suitable programmes.
Resorting to accredited suppliers of Proficiency Testing Schemes brings major benefits to laboratories, the most important being the fact that assessment is carried out by professional experts with proven competence, which consequently contributes to a marked increase of the level of confidence in the results produced.
ielab is accredited by the Spanish National Accreditation Body (ENAC in Spanish), with accreditation no. 2/PPI007, to carry out proficiency tests in laboratories following ISO/IEC standard 17043 and guides ILAC-G13:08/2007 and CGA-ENAC-PPI.
