Sélection du prestataire de métrologie : comment l’incertitude d’étalonnage affecte la précision de vos essais et vos risques
Chaque mesure comporte un certain degré de variabilité — et l’ampleur de cette variabilité détermine le niveau de risque que vous assumez. L’incertitude d’étalonnage affecte la précision de vos résultats d’essais, votre conformité aux normes d’essai et la qualité des produits que vous expédiez. Cet article développe la série de vidéos d’Instron du même nom, en expliquant ce qu’est l’incertitude d’étalonnage, comment évaluer ce qu’un certificat d’étalonnage indique réellement et ce qu’il faut rechercher lors du choix d’un prestataire — y compris le domaine d’accréditation, les valeurs d’incertitude publiées et la manière dont les décisions de conformité (succès/échec) sont prises.

Why is Pendulum Impact Testing Important in Research
Charpy and Izod impact tests play a vital role in the plastic chain, especially in raw material supply and recycling applications. The impact strength is one of the most crucial properties for polymer-based materials and it is commonly seen on materials data sheets. Knowing the impact strength of plastics allows manufacturers to classify the materials for specific purposes.
