Področje projekta (angleško): This International Standard specifies the methodology for the regular monitoring of the test method precision achieved versus precision published in the standard test method using data from Proficiency Testing Programs (PTP) supported by the regular users of standard test methods. The procedures in this International Standard are designed specifically for PTPs conducted on standard test methods for petroleum and petroleum related products, which are presumed to be homogeneous. The procedures in this document are designed specifically for standard test methods with published reproducibility derived from ISO 4259-1 or equivalent (such as ASTM D6300[1]) for petroleum and petroleum related products, which are normally considered as homogeneous. In particular, this document specifies the methodology for the statistical comparison of standard deviation under reproducibility conditions achieved in PTP versus that published. Purpose of this comparison is to ascertain if the published reproducibility precision is representative of that achievable by the regular participants in the PTP.
