Contribution à la mise en conformité des essais mécaniques aux normes dans une entreprise industrielle

Abstract

This end-of-studie project aims to contribute to the implementation of the ISO/IEC 17025 accreditation, which concerns the competence of calibration and testing laboratories, within the Algerian Qatari Steel (AQS Bellara) company. The objective was to address the problems encountered by the company in terms of technical requirements related to resources (personnel, environmental conditions, equipment) and process requirements (method validation, measurement uncertainty evaluation) which were carried out on the optical emission spectrometry test (carbon content) and the tensile test (yield strength and tensile strength). The proposed and implemented solutions represent tangible evidence that will be added to the company's accreditation dossier.
