Overview
This document specifies the process and methodology for the construction, operation, and maintenance of statistical control charts to assess if a laboratory's execution of a standard test method is in-statistical-control and how to establish and validate the 'in-statistical-control' status. This document (EN ISO 4259-4:2022) has been prepared by Technical Committee ISO/TC 28 "Petroleum and related products, fuels and lubricants from natural or synthetic sources" in collaboration with Technical Committee CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin", the secretariat of which is held by NEN (Netherlands). The responsible German standardization committee is Working Committee NA 062-06-16 AA "Präzision von Prüfverfahren" ("Precision of test methods") of Section "Mineralöl- und Brennstoffnormung (FAM)" ("Standardization of mineral oils and combustible materials") at DIN Standards Committee Materials Testing (NMP).
