Full title and description

ISO 10307-2:2009 — Petroleum products — Total sediment in residual fuel oils — Part 2: Determination using standard procedures for ageing. This part of ISO 10307 specifies two accelerated ageing procedures (thermal and chemical) whose results, when combined with the hot filtration method of ISO 10307‑1, allow prediction of sediment formation and stability of residual fuel oils during storage and handling.

Abstract

ISO 10307-2:2009 defines Procedure A (thermal ageing) and Procedure B (chemical ageing) for accelerated ageing of residual fuel oils. After ageing, sediment is determined using the hot filtration technique described in ISO 10307‑1. The standard is intended to predict tendency to sedimentation and to support quality control and specification conformance of residual fuel oils.

Scope

Specifies two standardized accelerated-ageing procedures for residual fuel oils — Procedure A (thermal ageing) and Procedure B (chemical ageing) — and describes how to combine these ageing procedures with the hot filtration determination of total sediment given in ISO 10307‑1. The objective is to predict sediment formation and assess fuel stability for storage and handling.

Key topics and requirements

• Procedure A — thermal ageing: sample heated at 100 °C for 24 h to simulate thermal ageing effects prior to hot filtration.
• Procedure B — chemical ageing: sample diluted with a normal alkane (commonly hexadecane) and heated (100 °C for a short period, e.g. 1 h) to provoke asphaltene instability, then submitted to hot filtration.
• Hot filtration sediment determination is performed according to ISO 10307‑1 after ageing to quantify total sediment as a mass percentage.
• Requirements for apparatus, reagents (e.g., hexadecane purity), sample preparation, duplicate testing and result reporting (mass percent, test conditions, deviations) to ensure reproducibility.
• Safety and laboratory controls for handling hot samples and flammable/volatile reagents during ageing and filtration steps.

Typical use and users

Used by analytical laboratories, refinery and marine fuel quality control teams, fuel producers, purchasers (bunker operators), standards bodies and research organizations to evaluate stability and sediment-forming tendencies of residual fuel oils, to support specification compliance and to inform storage/handling decisions. National standards distributors and conformity assessment bodies also use this standard when adopting or referencing ISO test methods.

Related standards

This part is intended to be used together with ISO 10307‑1 (Determination by hot filtration). The standard replaces ISO 10307‑2:1993 and has an associated corrigendum ISO 10307‑2:2009/Cor 1 (published to correct editorial/technical points). Related fuel testing standards and specifications (for example, fuel quality and bunker fuel specifications) may reference the ISO 10307 series for sediment testing.

FAQ

Q: What is this standard?

A: ISO 10307-2:2009 is an international test-method standard that specifies two accelerated ageing procedures for residual fuel oils so that sediment formation can be predicted and quantified when combined with the hot filtration method (ISO 10307‑1).

Q: What does it cover?

A: It covers Procedure A (thermal ageing) and Procedure B (chemical ageing) and the preparation and handling steps required so the aged samples can be evaluated by hot filtration for total sediment. The standard defines test conditions, equipment and reporting expectations.

Q: Who typically uses it?

A: Analytical and quality-control laboratories, refineries, fuel producers, marine bunker suppliers and purchasers, and standards and conformity-assessment bodies that need to measure or control sediment content and stability of residual fuel oils.

Q: Is it current or superseded?

A: ISO 10307-2:2009 (Edition 2) replaced the 1993 edition. According to ISO bibliographic records the 2009 edition remains the published/confirmed version and it has an associated corrigendum (ISO 10307‑2:2009/Cor 1). Users should check national adoption or corrigenda for any editorial corrections or national implementations.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 10307 series (Part 1 covers hot filtration determination of total sediment). The two parts are used together: Part 2 defines ageing procedures and Part 1 defines the hot filtration measurement.

Q: What are the key keywords?

A: Residual fuel oil, total sediment, hot filtration, accelerated ageing, thermal ageing, chemical ageing, fuel stability, hexadecane, ISO 10307.
