Petroleum and related products - Precision of measurement methods and results - Part 2: Interpretation and application of precision data in relation to methods of test (ISO 4259-2:2017)
ISO 4259-2:2017 specifies the methodology for the application of precision estimates of a test method derived from ISO 4259‑1. In particular, it defines the procedures for setting the property specification limits based upon test method precision where the property is determined using a specific test method, and in determining the specification conformance status when there are conflicting results between supplier and receiver. Other applications of this test method precision are briefly described in principle without the associated procedures.
The procedures in ISO 4259-2:2017 have been designed specifically for petroleum and petroleum-related products, which are normally homogeneous. However, the procedures described in ISO 4259-2:2017 can also be applied to other types of homogeneous products. Careful investigations are necessary before applying ISO 4259-2:2017 to products for which the assumption of homogeneity can be questioned.

Produits pétroliers et connexes - Fidélité des méthodes de mesure et de leurs résultats - Partie 2: Application des valeurs de fidélité relatives aux méthodes d'essai (ISO 4259-2:2017)
Le présent document prescrit la méthodologie pour l'application des estimations de fidélité d'une méthode d'essai déterminée selon l'ISO 4259‑1. En particulier, il définit les procédures à suivre pour fixer les limites de spécification d'une caractéristique sur la base de la fidélité de la méthode d'essai qui permet de déterminer la caractéristique en utilisant une méthode d'essai spécifique et pour déterminer l'état de conformité à une spécification quand il y a des résultats contradictoires entre le fournisseur et le destinataire. D'autres applications de cette fidélité des méthodes d'essai sont brièvement décrites en principe sans les procédures associées.
Les procédures du présent document ont été conçues spécifiquement pour les produits pétroliers et leurs produits connexes qui sont normalement homogènes. Les procédures décrites dans le présent document peuvent cependant aussi s'appliquer à d'autres types de produits homogènes. Il est nécessaire de procéder à des contrôles attentifs avant d'appliquer le présent document à des produits pour lesquels la présomption d'homogénéité peut être mise en question.
Nafta in sorodni proizvodi - Natančnost merilnih metod in rezultatov - 2. del: Razlaga in uporaba podatkov o natančnosti preskusnih metod (ISO 4259-2:2017)
Ta dokument določa metodologijo za uporabo ocen natančnosti preskusne metode iz standarda ISO 4259-1. Določa predvsem postopke za določitev omejitev specifikacij lastnosti na podlagi natančnosti preskusne metode, če se lastnost določi z uporabo posebne preskusne metode,
in pri določanju statusa skladnosti specifikacije, če med dobaviteljem in prejemnikom obstajajo nasprotujoči si rezultati. Drugi načini uporabe natančnosti te preskusne metode so na kratko opisani brez povezanih postopkov.
Postopki v tem dokumentu so bili zasnovani posebej za nafto in sorodne proizvode, ki so običajno homogeni. Kljub temu se postopki, opisani v tem dokumentu, lahko uporabljajo pri drugih vrstah homogenih proizvodov. Pred uporabo tega dokumenta za proizvode, pri katerih je predpostavka o homogenosti lahko vprašljiva, so potrebne temeljite preiskave.
