ABSTRACT
Traceability consists of the knowledge of an object or an action and the various actors involved at a given period of time. This notion appeared very early in terms of "quality" and has been extended to "quality management" which is the object of the standard ISO 17025. Traceability of measurements consists in recording data at the time of measurement. The different situations (linked to an identical or derived measurand) and the exploitation of these attachments (use of calibration certificates, interest, etc.) are explained in this article.

INTRODUCTION
The term "traceability" has been around for many years. Traceability means knowing the origin of an object, a being or an action.
In terms of "quality", then quality assurance and, finally, quality management (through ISO 17025), the notion of traceability appeared very early on.
As part of a quality approach, an accredited or certified laboratory must ensure traceability of the methods, consumables, technicians, environment and equipment used during analysis, testing or calibration.
In short, measurement traceability involves recording all the data at the time a laboratory technician performs a measurement.
