Full title and description

STB UNE-EN 13016-1:2018 — Liquid petroleum products — Vapour pressure — Part 1: Determination of air saturated vapour pressure (ASVP) and calculated dry vapour pressure equivalent (DVPE). This is a national adoption of the European Standard EN 13016-1:2018 describing a laboratory method to determine the total vapour pressure (air‑saturated vapour pressure, ASVP) of volatile, low‑viscosity petroleum products and to calculate the equivalent dry vapour pressure (DVPE) under defined test conditions.

Abstract

This standard specifies a vacuum method for measuring the air‑saturated vapour pressure (ASVP) of volatile, low viscosity petroleum products, components and ethanol blends (up to 85 % V/V), and describes calculation of the dry vapour pressure equivalent (DVPE) from the measured ASVP. The test is performed at a vapour‑to‑liquid ratio of 4:1 and a reference test temperature of 37.8 °C. The method is intended for fuel classification, emissions assessment and quality control in laboratories and production facilities.

General information

• Status: Superseded nationally (2018 edition). Replaced at European level by EN 13016-1:2024.
• Publication date: 2018 (EN approval and publication in spring 2018; national adoption dates may vary).
• Publisher: National adoption as STB UNE-EN (national standards body) — originally published by CEN (Comité Européen de Normalisation) as EN 13016-1:2018.
• ICS / categories: 75.160.20 (Liquid fuels); 17.100 (Measurement of force, weight and pressure).
• Edition / version: 2018 edition (first EN 2018 edition for Part 1) — note: EN 13016-1 was revised in 2024.
• Number of pages: Typically 17–22 pages depending on national publication format (commonly quoted as 19 pages).

Scope

The standard applies to volatile, low viscosity petroleum products, components, ethanol–fuel blends up to 85 % (V/V) and feedstocks that may contain air. It specifies the principle, apparatus, sample preparation, calibration and verification, test procedure, calculation of results and reporting for determination of ASVP (total pressure exerted in vacuo) and the derived DVPE. The method is defined for a vapour‑to‑liquid ratio of 4:1 at a test temperature of 37.8 °C and is suited to materials with DVPE in a defined range (precision determined within stated DVPE limits).

Key topics and requirements

• Definition and measurement of air‑saturated vapour pressure (ASVP) in vacuum conditions.
• Calculation method for dry vapour pressure equivalent (DVPE) from ASVP measurements.
• Specified test conditions: vapour‑to‑liquid ratio 4:1 and test temperature 37.8 °C.
• Sample types covered: volatile, low viscosity petroleum products, components and ethanol blends up to 85 % (V/V).
• Apparatus requirements, calibration and verification procedures to ensure traceable results.
• Sample handling and preparation requirements (including treatment when oxygenates are present); dissolved water is not taken into account.
• Precision and repeatability statements with DVPE measurement ranges for which precision has been established.
• Required contents of the test report and expression of results, including units and reference conditions.
• Safety note: use of hazardous materials and equipment — users must address local safety and regulatory requirements.

Typical use and users

Used by fuel test laboratories, refinery quality control departments, blending and distribution operations, regulatory and conformity assessment bodies, research laboratories and manufacturers of petroleum products. Typical applications include fuel classification, verification of product specifications, emissions risk assessment, and compliance testing for marketing and transport regulations.

FAQ

Q: What is this standard?

A: It is the national adoption (STB UNE-EN) of EN 13016-1:2018, a laboratory method for determining air‑saturated vapour pressure (ASVP) and calculating dry vapour pressure equivalent (DVPE) for volatile petroleum products and ethanol blends.

Q: What does it cover?

A: It covers test principle, apparatus, sampling and sample preparation, calibration and verification, test procedure, calculation of ASVP and DVPE, precision, and reporting requirements. Tests are carried out at a vapour‑to‑liquid ratio of 4:1 and 37.8 °C; dissolved water is not taken into account.

Q: Who typically uses it?

A: Accredited and industrial testing laboratories, refineries, fuel producers and blenders, distributors, regulatory agencies, and anyone needing standardized vapour‑pressure data for product specification, safety, transport or emissions assessments.

Q: Is it current or superseded?

A: The 2018 edition is now superseded at European level by a later revision (EN 13016-1:2024). National adoptions of the 2018 text may have been withdrawn or superseded; users should adopt the 2024 edition for the most up‑to‑date requirements and consult their national standards body for the current national designation.

Q: Is it part of a series?

A: Yes — EN 13016 is a multi‑part series. Part 1 covers ASVP and DVPE calculation, Part 2 covers absolute vapour pressure (AVP) methods, and Part 3 covers the triple expansion method for vapour pressure and DVPE. These parts are used together depending on the sample and application.
