The 1st CAFMET webinar was held on 26th of January 2021, from 2:00 P.M to 4:00 P.Mand concerned the

« "the International System of Units". »


This 1st webinar was moderated by Professor Marc HIMBERT (LCM-CNAM-LNE).


A new definition of the units of the International System of Units (SI) was adopted at the 26rd General Conference on Weights and Measures (CGPM) in November 2019. The new system of units is now based on fundamental physical constants. It is a more coherent choice, in harmony with quantum and relativistic physics, as well as with the most recent measurement techniques, which can only favor new technologies. The kilogram, represented since 1889 by the international prototype, nicknamed the "big K", kept at the Bureau International des Poids et Mesures (BIPM) in Sèvres, near Paris, is now, like most other units, dematerialized. After having recalled the causes, the means and the advantages of such a dematerialization of the units, this 1 Translated with (free version)st Le webinaire de CAFMET passera en revue certaines méthodes de mesure nouvelles et plus précises permettant d'établir la traçabilité sur une très grande surface, notamment la mise en œuvre de principes de mesure basés sur la physique quantique.




Professor Marc HIMBERTMr. Brossel, a graduate of the École Normale Supérieure, worked for ten years at the Laboratoire Kastler Brossel as a CNRS researcher in atomic physics, quantum physics and laser physics. He then joined the Conservatoire National des Arts et Métiers in Paris, where he has been director of the Chair of Metrology since 1992 and the Laboratoire Commun de Métrologie (LCM) created in 2008 in partnership with the LNE. It is in his laboratory, in particular, that very high accuracy measurements of the Boltzmann constant k and the Planck constant h were performed prior to the change of definition of international units in 2018-2019. He is a member of the Consultative Committee for Units (CCU) that coordinated the revision of the 2018-2019 unit definitions, and of the "Science and Metrology" Committee of the French Academy of Sciences. Since 2004, he has chaired the "Laboratories" section of the French Committee for Accreditation (COFRAC). Co-author of about 180 publications or scientific communications, he became a full member of the Académie des technologies in 2009. Professor Marc HIMBERT has chaired several international conferences organized by CAFMET. Translated with (free version)

The 2nd CAFMET webinar took place on February 25, 2021 from 3:00 pm to 5:00 pmvrier 2021 de 15h00 à 17h00 and involved

"TUNAC accreditation: achievements and prospects


It was animated by Sonia MADOUI MELKI (TUNAC) and Ghada ALLANI (TUNAC).



It is important to assure the market that conformity assessment bodies operate on the basis of recognized international standards, and this is the rationale for accreditation and the creation of TUNAC.

The accreditation process establishes, in the public interest, the technical competence and integrity of these organizations. Conformity assessment is the demonstration that the service provided does in fact meet the specified or claimed requirements.

Conformity assessment can be applied to a product, a service, a process, a system, an organization or a person, and includes activities such as testing, inspection or certification. Measurements also play an essential role in building confidence between trading partners and in demonstrating that products conform to written specifications and legal requirements, so connection to the international SI unit system is important and conformity assessment bodies must ensure metrological traceability.

This CAFMET Webinar was an opportunity for TUNAC to share its experiences and review the benefits of accreditation and its importance, the reasons for making it mandatory in certain sectors, as well as the means that must be adopted by conformity assessment bodies to ensure metrological traceability.



 Madam Sonia MADHOUI MELKI is an engineer in food industries. Her professional career began in September 1997 with her recruitment as a production manager and quality management manager in the JOUDA canning factory in Kairouan - Tunisia. Since September 1998, she joined the National Accreditation Council "TUNAC" as a quality management manager. 



Madam Ghada ALLANI has a degree in Food Industry Engineering with a professional master's degree in Innovation Management. She started her career as an engineer in Allani Sunlife Holding, responsible for the drying of agricultural products. She then joined TUNAC in 2015 as an accreditation manager for food testing laboratories (ISO/IEC 17025) and appointed since 2020 as an accreditation manager for food certification bodies (ISO/IEC 17065). She taught at INSAT (National Institute of Applied Sciences and Technology) the ISO/IEC 17025 standard and ISO 9001 in the framework of a professional master.

The March 30, 2021 took place le 3rd CAFMET webinar, organized in collaboration with DELTAMU, on the

"Metrology for Artificial Intelligence"

It was moderated by Jean-Michel POU (DELTAMU, France).


Questions related to periodic connections to international standards, to the conformity of measuring instruments and to measurement uncertainties are now at the heart of the profession of industrial metrologists

The industry is now interested, and more and more every day, in digitalization. At the heart of the industry of the future, namely Industry 4.0, this " digitization "seems to promise significant productivity gains, using the " Big Data "to feed the algorithms of Artificial Intelligence (AI). This A.I. should help us to better understand our processes in order to reach the Holy Grail of " defects "and the " right the first time ". These objectives are perfectly in line with the current crucial issue of better management of resources, whether energy or raw materials: " Doing what is necessary ».

Since its creation in 2005, CAFMET's mission is to promote best practices in metrology and quality. It also strives to carry out a technology watch to guarantee up-to-date information. CAFMET is firmly committed to this mission by proposing, in partnership with the company DELTAMU, this free webinar during which the speakers will present the stakes of A.I. in the industrial world and the role that metrology must now play.

En avant-première, il sera question de présenter la création d’une nouvelle licence « Data analyst industriel », co-construite par l’Université Cheikh Anta Diop de Dakar au Sénégal, l’Institut National Polytechnique Houphouët-Boigny en Côte d’Ivoire et SIGMA Clermont-Ferrand en France. Cette licence ouvrira ses portes en mode « 100% digital » pour la partie des cours théoriques dès septembre 2021.



Jean-Michel POU

Après 10 ans dans un laboratoire d’étalonnage, passant du poste de technicien d’étalonnage à responsable d’accréditation COFRAC puis directeur général, Jean-Michel POU décide de créer en 1998 sa propre société. DELTAMU s’inscrit depuis toujours dans une vision de la métrologie très différente de celle, historique, qu’il juge pas toujours adaptée par rapport aux besoins industriels. Pour lui, le métrologue doit participer, aujourd’hui plus que jamais, à la performance globale de son entreprise…

Un véritable passionné de métrologie, métier qu’il découvre à la fin de ses études, Jean-Michel POU a décidé de créer la société DELTAMU pour changer les pratiques industrielles. Convaincu qu’il ne suffit pas de vérifier tous les ans les instruments de mesure pour garantir la fiabilité des résultats de mesure, il s’engage pour défendre librement sa vision du métier de métrologue.

A ce jour, Jean-Michel POU participe à la grande révolution 4.0 actuellement en cours dans le monde industriel. Il est notamment Ambassadeur pour la Région Auvergne-Rhône-Alpes de l’Alliance Industrie du Futur et Vice-Président de l’association AURA Industrie 4.0, née de la fusion du cluster d’excellence Auvergne Efficience Industrielle et du pôle de compétitivité Mont-Blanc Industries. Il est également l’un des initiateurs du Mastère© spécialisé labélisé Conférence des Grandes Ecoles et porté par l’école d’ingénieurs SIGMA Clermont : « Data Science pour l’Ingénierie ». Il est par ailleurs directeur associé du consortium Humantodata, spécialisé dans l’accompagnement des industriels dans la révolution numérique.


CAFMET is an international non-profit, independent and impartial body. Since 2005, it has contributed to the good development of Metrology and Quality, particularly in Africa.
