Petroleum and related products — Precision of measurement methods and results — Part 2: Interpretation and application of precision data in relation to methods of test
Description
This document specifies the methodology for applying precision estimates of a test method derived from the processes specified in ISO 4259-1. In particular, it specifies the procedures for setting the property specification limits based upon test method precision where the property is determined using a specific test method, and determines 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 this document have been designed specifically for petroleum and petroleum-related products, which are normally homogeneous. However, the procedures described in this document can also be applied to other types of homogeneous products.
This document is not applicable to non-homogenous products.

This document specifies the methodology for applying precision estimates of a test method derived from the processes specified in ISO 4259-1. In particular, it specifies the procedures for setting the property specification limits based upon test method precision where the property is determined using a specific test method, and determines 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 this document have been designed specifically for petroleum and petroleum-related products, which are normally homogeneous. However, the procedures described in this document can also be applied to other types of homogeneous products.
