ISO 10307-2:2009 specifies two procedures — A (thermal) and B (chemical) — for the accelerated ageing of residual fuel oils. When combined with the hot filtration method specified in ISO 10307-1, these procedures permit the prediction of fuel oil stability, as affected by sedimentation, during storage and handling of the fuel oils.

Overview

ISO 10307-2:2009 defines standardized procedures for determining total sediment in residual fuel oils through accelerated ageing methods. It complements ISO 10307-1, which covers sediment determination by hot filtration. By specifying two accelerated ageing procedures-thermal (Procedure A) and chemical (Procedure B)-this International Standard allows petroleum industry professionals to predict the stability of residual fuel oils during storage and handling. The presence and quantity of sediment are critical indicators of fuel quality, affecting operational reliability in storage tanks, pipelines, and combustion systems.

Key Topics

Accelerated Ageing Procedures

Procedure A (Thermal Ageing): Samples are aged at 100 °C for 24 hours under controlled conditions to simulate long-term sediment formation.
Procedure B (Chemical Ageing): Samples are diluted with hexadecane (normal alkane) and aged at 100 °C for 1 hour. This chemically disturbs the balance of asphaltenes leading to sediment precipitation.

Sediment Determination Method Following ageing, sediment determination is performed using hot filtration per ISO 10307-1. Both procedures are carried out in duplicate to ensure data reliability.

Equipment and Reagents Standardized lab apparatus includes an ageing bath with precise temperature control, air condensers, magnetic stirrers, and specialized glassware complying with ISO laboratory standards. Hexadecane of ≥99% purity is used in chemical ageing.

Result Reporting Sediment content is calculated as a mass percentage with accuracy to 0.01%, detailing whether results correspond to potential sediment (thermal ageing) or accelerated sediment (chemical ageing). Reports include test conditions, specimen identification, and any procedural deviations.

Safety Considerations Users must adhere to safety protocols due to handling of hazardous materials at high temperatures and potential chemical exposure during testing.

Applications

Fuel Quality Control ISO 10307-2 allows fuel storage and quality assurance labs to predict the sedimentation behavior of residual fuel oils, helping to prevent operational issues caused by sediment deposits.

Fuel Formulation and Stability Assessment Petroleum producers and blenders can evaluate fuel formulations for long-term stability, ensuring compliance with industry specifications and reducing downtime caused by sludge formation.

Storage and Handling Risk Management Facilities can assess the likelihood of sediment precipitation over time, allowing better maintenance scheduling and reducing risks associated with filter clogging and equipment fouling.

Regulatory and Contract Compliance Standardized sediment testing supports compliance with contractual fuel quality requirements and regulatory standards, promoting harmonized practices across international markets.
