Their producers either hold ISO 17034 accreditation for at least some of the materials they list or provide their CRMs as a National Metrology Institute (NMI) or Designated Institute (DI). </p> <p>The COMAR database is maintained by the COMAR Consortium, a collaboration of NMIs, DIs, and national laboratories worldwide. This initiative dates back to the 1970s, when the Laboratoire National de Métrologie et d'Essais (LNE) in France introduced the <em>Code d'Indexation des Matériaux de Référence</em> (COMAR). In the early 1980s, LNE partnered with the National Physical Laboratory (NPL) in the United Kingdom and the Bundesanstalt für Materialforschung und -prüfung (BAM) in Germany to develop a shared database listing CRMs available in their respective countries. This effort was financially supported by the European Commission.</p> <p>Together, these organizations formed the COMAR Consortium, establishing a joint <a href="r/eptiscomar/f_103106107107200990333500400/pdf-viewer?p11_id=22&clear=Y&session=13915026906925&cs=1rwaJ5M8Pu_nS0kFAXgQCL5b9a78">Protocol</a> that governed their collaboration. While the Protocol holds mainly historical significance today, the project has continued to grow—both in the number of listed CRMs and in the economies that have joined the Consortium.</p> <p>Originally an offline resource, the database went online in 2001 and underwent a complete redevelopment in 2022 and again in 2024, resulting in the version you see on this website. The most recent update was necessary due to BAM’s transition away from labor-intensive Java applications toward Oracle APEX, a robust, out-of-the-box solution that is easier to maintain.</p> The current members of the COMAR Consortium include:</td> </tr> <tr style="height: 349.385px;"></tr> <tr style="vertical-align: top; height: 698.385px;"> <td style="border-style: hidden; height: 698.385px; border-width: 1px;"> <h2 style="padding-left: 40px;"><span style="color: rgb(35, 111, 161); font-size: 24pt;">Americas</span></h2> <div> <div><strong>Brazil</strong></div> <div style="padding-left: 40px;"><a data-original-title="Institute Website" data-toggle="tooltip" rel="noopener" target="_blank" href="https://www.gov.br/inmetro" title="">Inmetro Instituto Nacional de Metrologia, Qualidade e Tecnologia</a>  </div> <div style="padding-left: 40px;">Janaína Marques Rodrigues Caixeiro      jmrodrigues-at-inmetro.gov.br</div> <div> <div><strong>Canada</strong></div> <div style="padding-left: 40px;"><a rel="noopener" target="_blank" href="https://nrc.canada.ca/">National Research Council Canada</a></div> <div style="padding-left: 40px;">Patricia Grinberg      Patricia.Grinberg@nrc-cnrc.gc.ca</div> </div> <div> <div><strong><span class="pull-right">Mexico     </span></strong></div> <div> <div style="padding-left: 40px;"><a data-original-title="Institute Website" data-toggle="tooltip" rel="noopener" target="_blank" href="https://www.gob.mx/cenam/" title="">CENAM National Center of Metrology</a>  </div> <div style="padding-left: 40px;">Judith Sainz Uribe      gsainz-at-cenam.mx</div> <div> <div> <div style="padding-left: 40px;"> </div> </div> </div> </div> </div> </div> <h2 style="padding-left: 40px;"><span style="color: rgb(35, 111, 161); font-size: 24pt;">Asia</span></h2> <div> <div><strong><span class="pull-right">China     <br></span></strong></div> <div> <div style="padding-left: 40px;"><a data-original-title="Institute Website" data-toggle="tooltip" rel="noopener" target="_blank" href="https://en.nim.ac.cn/taxonomy/term/122">NIM National Institute of Metrology</a></div> <div style="padding-left: 40px;">Lin Lu      lulin-at-nim.ac.cn</div> </div> </div> <div><strong><span class="pull-right">India     </span></strong></div> <div> <div style="padding-left: 40px;"><a data-original-title="Institute Website" data-toggle="tooltip" rel="noopener" target="_blank" href="https://www.nplindia.org/" title="">NPL National Physical Laboratory</a> </div> <div style="padding-left: 40px;">S.
