Petroleum and related products — Precision of measurement methods and results — Part 5: Statistical assessment of agreement between two different measurement methods that claim to measure the same property

This document specifies statistical methodology for assessing the expected agreement between two test methods that purport to measure the same property of a material, and for deciding if a simple linear bias correction can further improve the expected agreement. This document is applicable for analytical methods which measure quantitative properties of petroleum or petroleum products resulting from a multi-sample-multi-lab study (MSMLS). These types of studies include but are not limited to interlaboratory studies (ILS) meeting the requirements of ISO 4259-1 or equivalent, and proficiency testing programmes (PTP) meeting the requirements of ISO 4259-3 or equivalent. The methodology specified in this document establishes the limiting value for the difference between two results where each result is obtained by a different operator using different apparatus and two methods X and Y, respectively, on identical material. One of the methods (X or Y) has been appropriately bias-corrected to agree with the other in accordance with this practice. This limit is designated as the between-methods reproducibility. This value is expected to be exceeded with a probability of 5 % under the correct and normal operation of both test methods due to random variation. NOTE Further conditions for application of this methodology are given in 5.1 and 5.2.

Produits pétroliers et connexes — Fidélité des méthodes de mesure et de leurs résultats — Partie 5: Évaluation statistique de l'accord entre deux méthodes de mesure différentes qui prétendent mesurer la même propriété

Le présent document spécifie une méthodologie statistique permettant d'évaluer l'accord attendu entre deux méthodes d'essai qui prétendent mesurer la même propriété d'un matériau et de déterminer si une simple correction de biais linéaire peut encore améliorer l'accord attendu. Le présent document est applicable à des méthodes d'analyse qui mesurent des propriétés quantitatives du pétrole ou des produits connexes résultant d'une étude multi-échantillon et multi-laboratoire (MSMLS). Ces types d'études comprennent les essais interlaboratoires (ILS) conformes aux exigences de l'ISO 4259-1, ou équivalent, et les programmes d'essais d'aptitude (PTP) conformes aux exigences de l'ISO 4259-3, ou équivalent, sans toutefois s'y limiter. La méthodologie spécifiée dans le présent document établit la valeur limite de la différence entre deux résultats, lorsque chaque résultat est obtenu par un opérateur différent utilisant un appareil différent et appliquant les deux méthodes X et Y, respectivement, sur un matériau identique. L'une des méthodes (X ou Y) a fait l'objet d'une correction de biais appropriée pour être en accord avec l'autre méthode conformément à ce mode opératoire. Cette limite est désignée comme la reproductibilité inter-méthodes. Il est attendu, avec une probabilité de 5 %, que cette valeur soit dépassée dans les conditions normales et correctes d'application de ces deux méthodes en raison de la variation aléatoire. NOTE Les conditions supplémentaires pour l'application de cette méthodologie sont données en 5.1 et 5.2.
