Overview

EN ISO 4259-1:2017/A2:2020 (ISO 4259-1:2017/Amd 2:2020) is a CEN-adopted amendment to Part 1 of the ISO 4259 series: "Petroleum and related products - Precision of measurement methods and results - Part 1: Determination of precision data in relation to methods of test." This Amendment 2 (approved December 2020 and adopted by CEN) updates key precision terminology and the formal description of how repeatability and reproducibility limits are expressed and applied for petroleum test methods.

Key topics

  • Precision terminology updates
    • Revised definitions for repeatability limit and reproducibility limit as quantitative expressions of random error associated with the difference between two independent results, expected to be exceeded with an approximate probability of 5%.
  • New procedural terms
    • Added definitions for repeatability conditions (same method, same laboratory, same operator, same equipment, short intervals) and reproducibility conditions (same method in different laboratories: different operator, different equipment, different location, differing supervisory control).
  • Calculation context
    • Clause 6.4.1 (X.2 and X.3) wording replaced to standardize the description of how the difference between two independent results (under repeatability or reproducibility conditions) is interpreted and calculated - specifically describing the 5% exceedance probability and referencing the functions used to compute those differences.
  • Scope context
    • Applies to petroleum and related products testing and volumetric/measurement equipment contexts (ICS: 75.080; 75.180.30).

Applications

This amendment supports consistent determination and reporting of precision data across laboratories and organizations involved in petroleum testing. Typical uses include:

  • Test laboratories validating method performance and reporting repeatability and reproducibility limits.
  • Quality control teams in oil, fuel and lubricant production applying precision limits to acceptance criteria.
  • Interlaboratory comparisons, proficiency testing and method validation where standardized precision definitions are required.
  • Standards committees, accreditation bodies and metrology specialists using harmonized language for conformity assessment (e.g., ISO/IEC 17025 contexts).
  • Instrument and test-equipment manufacturers ensuring declared measurement uncertainty aligns with recognized precision definitions.

Related standards
