Full title and description

STB DIN EN ISO 8222 A-1 E 2021-09 — Petroleum measurement systems — Calibration — Volumetric measures, proving tanks and field measures (including formulae for properties of liquids and materials); this listing corresponds to a national/adopted amendment document (A‑1) and related German/EN adoptions of ISO 8222 (original ISO publication: ISO 8222:2020).

Abstract

This standard specifies requirements and guidance for the design, use and calibration of volumetric measures (capacity measures), proving tanks and field measures used for petroleum and related liquid measurement. It includes guidance on standard and non‑standard measures, portable and mobile measures, reference formulae for properties of water and other fluids, and typical calibration uncertainties. It excludes cryogenic liquids and pressurised LPG/LNG measures.

General information

• Status: Published — ISO international standard (ISO 8222:2020) with subsequent amendment activity and national/EN adoptions (A‑1 amendment / national draft versions).
• Publication date: ISO main publication 31 March 2020; national/EN amendment drafts and adoptions carrying A‑1 identifiers appeared in 2021 (e.g., DIN EN ISO 8222/A1:2021‑09) and the formal ISO amendment was published in January 2022.
• Publisher: International Organization for Standardization (ISO). National/European bilingual/adopted versions are published by national bodies (for example Deutsches Institut für Normung — DIN; STB denotes a national adoption listing).
• ICS / categories: 75.180.30 — Volumetric equipment and measurements.
• Edition / version: Edition 3 (ISO 8222:2020); amendment A‑1 (documented as ISO 8222:2020/Amd 1:2022 and as national/EN amendment drafts such as DIN EN ISO 8222/A1:2021‑09).
• Number of pages: 70 pages (ISO 8222:2020 main text). Amendment documents and national A‑1 publications are much shorter (typically 1–11 pages depending on the issuing body).

Scope

Applies to the calibration of volumetric measures, proving tanks and field measures used in petroleum measurement systems. The standard gives requirements and guidance for measuring volumes by wetted/drained and by contain methods, classification of measures (test measures, prover tanks), calibration procedures, expected calibration uncertainties, and provides reference formulae for properties of water and other fluids. It explicitly excludes measures for cryogenic liquids and pressurised LPG/LNG applications.

Key topics and requirements

• Definitions and classification of volumetric measures (test measures, prover tanks, field measures).
• Calibration procedures for volumetric measures and proving tanks, including handling, filling/draining practices and timing.
• Multiplication/correction factors and temperature correction guidance applied during capacity determination.
• Reference formulae for physical properties of water and other relevant fluids and materials used in volumetric measurement.
• Guidance on typical calibration uncertainties and acceptable uncertainty budgets for different measure types.
• Exclusions: cryogenic and pressurised LPG/LNG measures are out of scope and require separate standards.

Typical use and users

Used by national metrology institutes, calibration laboratories, petroleum companies, tank and measure manufacturers, field service technicians, quality/control engineers and regulators involved in custody transfer, inventory management and volumetric calibration of petroleum and liquid product storage and transport systems. Practically applied in lab-based calibrations and on-site field calibrations for delivery tanks and storage facilities.

Related standards

Closely related documents include ISO 8222:2020 (main text), ISO 8222:2020/Amd 1:2022 (Amendment 1 — typographical corrections), and the various EN / national adoptions (for example EN ISO 8222:2020/A1:2022 and DIN EN ISO 8222/A1:2021‑09 and later DIN EN ISO 8222 editions). Other petroleum-measurement and tank-calibration standards (e.g., ISO and national standards on strapping, manual tank gauging and uncertainty calculation) are commonly used alongside ISO 8222.

FAQ

Q: What is this standard?

A: ISO 8222 is an international standard that specifies requirements and guidance for the calibration of volumetric measures, proving tanks and field measures used in petroleum measurement systems; the A‑1 identifier refers to an amendment/national adoption document associated with the ISO 8222 text.

Q: What does it cover?

A: It covers design, use and calibration methods for volumetric measures (including portable and mobile measures), classification of measures, reference formulae for fluid properties, temperature correction guidance and typical uncertainty expectations. It excludes cryogenic and pressurised LPG/LNG measure applications.

Q: Who typically uses it?

A: Calibration laboratories, metrology institutes, petroleum companies, tank manufacturers, field calibration technicians, and regulators responsible for custody transfer and inventory control.

Q: Is it current or superseded?

A: The core ISO 8222:2020 (Edition 3) is the current international text; an Amendment (ISO 8222:2020/Amd 1:2022) was published to correct typographical errors and national/EN amendment drafts carrying the A‑1 designation were issued in 2021–2022. Some national draft versions (e.g., DIN EN ISO 8222/A1:2021‑09) were later consolidated into subsequent DIN/EN publications — always check the national body for the effective national edition.

Q: Is it part of a series?

A: It is part of the set of ISO / CEN documents addressing petroleum measurement systems and calibration practices; related standards address specific tank‑calibration methods (strapping, manual gauging, uncertainty calculations) and other parts of petroleum measurement. Consult your national catalogue for linked EN or national standards.

Q: What are the key keywords?

A: Petroleum measurement, calibration, volumetric measures, proving tanks, temperature correction, capacity measure, calibration uncertainty, ISO 8222, amendment A‑1.
