Quality<\/h1>\n

VSL provides measurement accuracy and traceability to national and international measurement standards and manages and develops the Dutch standards. Undisputed quality and knowledge development are essential requirements. As an ongoing aspect of our operations, we work on the continuous quality of processes and maintaining our accreditations.

Quality<\/p>\n

Participation in international interlaboratory comparisons<\/h2>\n

VSL participates in international interlaboratory comparisons organised among national metrology institutes. These interlaboratory comparisons are always carried out nationally, regionally (i.e. at European level) and globally. Using a common measurement protocol as well as stable and similar measurement results, we can compare the artefacts (primary standards) with each other. At the same time, we exchange knowledge about the measurement methods used and the measurement results found. This provides evidence for current measurement capabilities and future reductions in measurement uncertainty.<\/p>\n

The results of the interlaboratory comparisons provide the measurement capabilities known as Calibration & Measurement Capabilities (CMCs). This information is publicly available and can be found on the (BIPM’s website <\/a>).[\/vc_column_text][\/vc_column][vc_column width=”1\/3″ el_class=”tablet_expert full_width_responsive”]

Mutual Recognition Arrangement (CIPM MRA).<\/h2>\n

VSL was one of the first participating institutes to sign the BIPM’s Mutual Recognition Arrangement (CIPM MRA) in 1999.<\/p>\n

This arrangement governs the mutual recognition of measurement standards of national metrology institutes (NMIs) worldwide. The certificates they issue are globally accepted on the basis of this recognition, on condition that NMIs ensure their measurement capabilities through key comparisons and maintain a quality system in accordance with international laboratory standards.<\/p>\n

EURAMET<\/strong>
\nEURAMET is an association of national metrology organisations from European Union member states and the European Free Trade Association. VSL is a member of EURAMET, through which it maintains its participation in the CIPM MRA. In accordance with the requirements of the MRA, VSL participates in EURAMET’s technical committees and its Quality Committee. VSL reports to this committee on functioning of the quality system and technical performance. VSL has chosen to demonstrate the competence of its activities by becoming an accredited body for calibration (K999: ISO\/IEC 17025<\/a>), the production of reference materials (P002: ISO 17034<\/a>) and the organisation of interlaboratory comparisons (R006: EN ISO\/IEC 17043<\/a>). Every year, subject-matter experts from other NMIs participate in the assessment examinations of the Dutch Accreditation Council RvA.[\/vc_column_text][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/vc_row][vc_row el_class=”dg-index-fix dg-padding-small-top”][vc_column width=”5\/6″ el_class=”dg-padding-none full_width_responsive”][vc_column_text css=””]Our accreditations:<\/p>\n
