Although the conformity assessment and management system standards offer a large flexibility to reference materials users regarding management and control of reference materials, numerous questions stay still open to users preparing a first assessment of their skills. This article aims has to answer has some of enter they to facilitate the dialogue between users and auditors. It presents different approaches recommended to assure traceability demonstration in audit situation, to verify the truthfulness of the Reference materials accompanying certificates and finally an approach of control of the processes of measure.
The ISO/IEC 17025 standard ‘General requirements for the competence of testing and calibration laboratories’ requires measurement methods to be validated when they are not standardised or when they are used outside the scope of application provided for by the standard, and to associate an uncertainty with the measurement value. Chemical analysis laboratories generally know how to validate their measurement methods, but they sometimes encounter difficulties in assessing measurement uncertainty. This document outlines the various ways, covered by the ‘Guide to the expression of uncertainty in measurement’ (GUM), of assessing it, using data from within or outside the laboratory.
Since the 2000 version of ISO 9001, the process-based approach has been at the heart of QMS structures. Despite its long history, however, the subject remains open to debate on several fronts, sparking controversies within the quality community that rival those of the Capulets and Montagues. This controversy centers on how to define processes: either by replicating the company’s hierarchical silos (sales/purchasing/engineering/production, etc.) or by defining cross-functional processes that align with end-to-end workflows, creating value for customers and other stakeholders. The drafters of ISO 9001 have refrained from taking sides in this ongoing controversy, likely fearing that there is more to lose than to gain from an initiative that could lead to a schism.
With each new version of ISO 9001, quality managers and their leadership teams have two questions on their minds: What’s new? What needs to be done, added, or changed in our organization’s QMS (quality management system)? This new version is somewhat paradoxical, as it includes several differences or changes from the current version without the text of ISO/DIS 9001 itself, at this stage, providing a clear explanation of the overall significance of these differences and changes. Building on its undeniable success and the experience gained over decades, the new version of ISO 9001 boldly reaffirms its core principles.
The new versions of ISO 9000 and ISO 9001 continue to be a major event for the community of users of these standards, even nearly forty years after the first version was released. This new version is, however, somewhat paradoxical, as it includes a large number of (minor) differences or changes compared to the current version, without really introducing any significant new requirements. Just as with the release of a new version of an iconic car model, we appreciate entering the new ISO 9000 and ISO 9001 standards on familiar ground, reassured to find our main points of reference, though sometimes with a touch of disappointment at the lack of boldness.
The risk of explosive atmospheres (ATEX) is frequent in laboratories due to the use of inflammable products(gases or liquids). A regulation has been drafted in order to improve the health and safety of workers exposed to the ATEX risk. This article is dedicated to the implementation of this regulation within laboratories. The regulation, its principles and main requirements as well as the definition of ATEX zones are firstly listed. The implementation of this regulation in laboratories is then presented on the basis of general information and illustrated with a few cases of common situations.
Conjugated polymers can be used as sensitive layers in chemical (bio)sensors, enabling the selective detection of a wide range of chemical or biological molecules in both liquid and gaseous environments by converting the presence of target molecules into an electrochemical or optical signal. The article begins by introducing conjugated polymers and their key properties, followed by an explanation of the operating principles of sensors that incorporate them. It then explores recent advancements in sensor technologies, methods for combining polymers with other functional components to enhance detection capabilities, and a selection of application examples.
The air quality of private and collective closed spaces depends on several sources of pollution which are at the origin of various physical, chemical and biological pollutants. This article presents the measurement tools, on site and in the laboratory (recording, sampling and analysis, sensors) and the circumstances of these measurements: delivery of a new or renovated building, operation or environmental investigation after reporting. It indicates the action to be taken in the event that the reference values of the parameters measured are exceeded. It specifies the preventive actions on the sources of pollution, the renewal of the air in the premises and the air treatment systems.
The purpose of this article is to review the knowledge concerning the radon risk, particularly from the angle of the assessment of the risk it generates in exposed persons. Elements will be provided on the physics of radioactive radon gas, then on exposure situations (mainly for France), on the means of measurement, and then detail the factors contributing to the quantitative dosimetric assessment of radon. Health risks will be addressed on the basis of contributions from international epidemiological and dosimetric studies. In conclusion, the aspect of communication and perception of the populations concerning the radon risk, a determining point for progress in the health situation, will be discussed.
Forms are part of our daily lives. Whether in our professional or personal environment, all our activities, requests or responses almost systematically pass through a form, in paper or, increasingly, computer format. A form is a specific document used to record the various information required by the recipient of the completed form, for a specific purpose (service request, inspection report, purchase order, account creation, incident report, etc.). To create an effective form, it's essential to define the purpose of the form and the data it should contain, taking into account both the sender and the recipient, who can be many and varied. In this sheet, we'll look at the steps involved in creating and implementing a form, so that it's efficient and easy to use.
