ISO 8222:2020/Amd 1:2022

Overview

ISO 8222:2020/Amd 1:2022 is an important amendment to the international standard ISO 8222:2020, which focuses on petroleum measurement systems. This standard deals specifically with the calibration of volumetric measures, proving tanks, and field measures used in the petroleum industry. It also includes essential formulae related to the properties of liquids and materials, ensuring accurate and reliable petroleum volume measurement.

The 2022 amendment primarily addresses corrections to two typographical errors in the original 2020 edition. These corrections enhance the precision and clarity of the standard, particularly in formulas and unit expressions, reinforcing the integrity of petroleum measurement calibrations worldwide.

Key Topics

• Calibration of Volumetric Measures
  Provides guidelines for calibrating tanks and field measuring devices to ensure precise volume measurement of petroleum products.

• Proving Tanks and Field Measures
  Defines methods to verify the accuracy and reliability of proving tanks used for volume calibration in various field conditions.

• Formulae for Properties of Liquids and Materials
  Includes critical equations to calculate liquid density, temperature, and pressure dependencies with minimal uncertainty, essential for correct volume corrections.

• Corrections to Typographical Errors

  • Corrected unit of density function uncertainty to 0.001 % within the temperature range of 0 °C to 40 °C and concentration range of 0 g/kg to 40 g/kg.
  • Updated exponent correction in formula (A.13), ensuring mathematical accuracy in liquid property predictions.

• Collaboration and Standardization
  Developed by ISO Technical Committee ISO/TC 28 and Subcommittee SC 2, in cooperation with CEN/TC 19, reflecting a global consensus for petroleum measurement calibration standards.

Applications

• Petroleum Industry Measurement Systems
  Vital for operators and engineers involved in measuring petroleum volumes at refineries, storage terminals, and distribution points, ensuring measurement traceability and compliance.

• Calibration Laboratories
  Provides standardized procedures for calibration labs to verify volumetric measures according to internationally recognized protocols.

• Regulatory Compliance
  Facilitates adherence to international trade and regulatory requirements for volume measurement accuracy, reducing trade disputes and improving measurement confidence.

• Quality Assurance in Fuel Distribution
  Ensures that field measuring devices and proving tanks deliver consistent and precise volumes, impacting commercial transactions and quality control processes.

• Design of Measurement Equipment
  Guides manufacturers in developing volumetric measurement devices that meet stringent accuracy requirements based on tested calibration methods and calculation formulae.

Related Standards
