Описание (английский):

This document specifies a method for the determination of the pour point of petroleum products. A separate procedure suitable for the determination of the lower pour point of fuel oils, heavy lubricant base stock, and products containing residual fuel components is also described. The procedure described in this document is not suitable for crude oils. NOTE There is equipment available that uses an automated procedure similar to the one described in this document. However, the precision thereof has not been established[1]. [1] ISO develops an automated test method standard.

Overview

ISO 3016:2019 - "Petroleum and related products from natural or synthetic sources - Determination of pour point" defines a laboratory method to determine the pour point (the lowest temperature at which a petroleum sample will continue to flow) for petroleum products. The standard describes apparatus, sampling, and a stepwise cooling and observation procedure. It also includes a separate procedure for determining the lower pour point of fuel oils, heavy lubricant base stocks and products containing residual fuel components. The procedure is not suitable for crude oils. Note: automated apparatus exist, but their precision has not been established in this edition.

Key topics and requirements

Scope and applicability: Applies to refined petroleum products and synthetic equivalents; excludes crude oils. Includes special treatment for samples with pour points above −33 °C and those at −33 °C and below.

Definition: Pour point = lowest temperature at which sample continues to flow under specified conditions.

Apparatus:

Test jar: clear glass, flat-bottomed, 30.0–32.4 mm inside diameter, 115–125 mm height, marked for 45 ml ± 1 ml.
Temperature measuring devices: digital contact thermometer (DCT) (specified in Annex A) or liquid‑in‑glass partial‑immersion thermometers (immersions: 3 mm below surface for glass thermometers; DCT probe 10–15 mm below surface).
Jacket, disc, gasket, cooling baths, timing device (accuracy 0.2 s).

Sampling: Follow ISO 3170 (manual) or ISO 3171 (automatic) unless otherwise specified.

Procedure:

Preliminary heating and controlled cooling at specified rates.
Observations of flow at intervals of 3 °C; tilt test and 5 s horizontal observation to confirm cessation of flow.
Special handling if sample was heated >45 °C (rest 24 h at room temperature).

Results and precision: Clause 8–9 cover expression of results and precision (aligned with ASTM D97). Annex C gives derived precision values. Annex B lists common chemicals and cooling mixtures; Annex A specifies temperature measuring device requirements.

Safety: Document contains a safety warning - users must address hazardous materials and operations.

Applications

Quality control and production testing in refineries, lubricant manufacturing, fuel blending and distribution.

Verifying cold‑weather performance and storage/transportation suitability of fuels and lubricants.

Specification compliance for commercial contracts and regulatory reporting.

Research and development for formulation of pour‑point depressants and low‑temperature additives.
