Remarks PT provider UCLSB/SSLSB has been operating as an organizer of proficiency testing through interlaboratory comparisons since 2008. It was accredited in December 2013 and it has been constantly updating and extending its scope of accreditation ever since. We have had more than 250 participants from more than 22 countries from Europe, Asia and Latin America. Our purpose is to be of help to the CABs and to satisfy their growing needs in the field of PT/ILC by helping them to discover their weak spots and approve their work. It is not about participating in a PT scheme, it is about getting the use of it and improve the quality of the testing process. We organize extra PT schemes in case such are desired by our clients. The extra PT schemes could be local (for a certain country) or international. It depends on the needs of the CABs. Interlaboratory technical project MC 07/2018 will be uploaded on EPTIS database soon. The PT programme for 2018 with the PT schemes will be available here shortly.
