Full title and description

ISO 10307-1:2009 — Petroleum products — Total sediment in residual fuel oils — Part 1: Determination by hot filtration. This laboratory test method specifies a hot‑filtration and solvent‑wash gravimetric procedure for measuring total sediment (insoluble organic and inorganic matter) in residual fuel oils (and in distillate blends that contain residual components).

Abstract

ISO 10307-1:2009 defines a procedure in which a measured aliquot of fuel is filtered at about 100 °C through a specified glass‑fibre filter, the retained material is washed with a defined heptane/toluene wash solvent, dried and weighed. Results are reported as mass fraction (% m/m), tests are performed in duplicate and the method includes requirements for sampling preparation, apparatus (filtration vessel, steam/heating medium, vacuum), reagents and expression of results. Typical reporting precision and handling limits are specified.

Scope

This part of ISO 10307 specifies a test method for the determination of total sediment in residual fuel oils having a maximum kinematic viscosity of 55 mm2/s at 100 °C and for blends of distillate fuels that contain residual components. The method is intended for laboratory quality control and stability assessment (including when used in combination with ageing procedures described in ISO 10307‑2). It is not a field screening technique but a laboratory gravimetric determination.

Key topics and requirements

• Principle: hot filtration of a measured aliquot at ~100 °C, solvent washing of retained material, drying and gravimetric weighing to calculate total sediment as % (m/m).
• Filtration temperature and heating: filtration is performed at about 100 °C (± specified tolerance) using steam or an equivalent controlled heating medium.
• Vacuum and filtration conditions: vacuum source set to an absolute pressure in the specified range (example: ~40 kPa ±2 kPa absolute), and filtration times are limited (procedures for slow filtration are specified).
• Filters and drying: specified glass‑fibre filters (nominal porosity) are used; filters are dried/conditioned and weighed after drying (oven temperature typically about 110 °C ±1 °C).
• Reagents/solvents: wash solvent is a defined blend (commonly 85 % heptane / 15 % toluene v/v) and analytical‑grade reagents are required; safety and ventilation for volatile hydrocarbons are emphasized.
• Sample preparation: homogenization (e.g., high‑speed mixer), controlled heating of viscous samples prior to testing, and references to sampling standards (ISO 3170 / ISO 3171) for correct sample collection.
• Expression of results: results reported as mass fraction (% m/m) to the stated reporting precision (typically to 0.01 % m/m), duplicate determinations with reporting conventions for values below detection thresholds.

Typical use and users

Used by fuel testing laboratories, refinery and blending quality control teams, fuel suppliers, marine fuel testers, terminal operators, ship and power plant engineers, and regulatory/inspection bodies. Typical applications include routine quality control, acceptance testing, stability studies, and investigation of fouling or burner problems caused by insoluble sediment.

Related standards

ISO 10307-1 is part of the ISO 10307 series; ISO 10307-2:2009 provides standard ageing procedures (thermal and chemical) that are used with the hot‑filtration method to assess potential sediment formation during storage and handling. Normative references in ISO 10307-1 include sampling standards ISO 3170 and ISO 3171 and reagent specification documents (e.g., ISO 6353‑2/3); historical or alternative sediment methods (e.g., extraction methods) are also noted.

FAQ

Q: What is this standard?

A: ISO 10307-1:2009 is an international laboratory test method that specifies a hot‑filtration and solvent‑wash gravimetric procedure to determine total sediment in residual fuel oils.

Q: What does it cover?

A: It covers the test principle, apparatus and conditions (filtration at ~100 °C, vacuum, specified glass‑fibre filters), reagents (wash solvent composition), sample preparation, test procedure (including duplicate determinations), calculation and reporting of results, and safety considerations.

Q: Who typically uses it?

A: Accredited and commercial fuel testing laboratories, refineries and blending plants, marine fuel analysts, terminals, ship operators and any organization needing to quantify insoluble sediment in fuel oils for quality, compliance or troubleshooting.

Q: Is it current or superseded?

A: The 2009 (Edition 2) text is the current published edition and has been subject to ISO periodic review (the edition was confirmed in review cycles). Users should check the national or ISO catalog for the latest confirmation or corrigenda before purchase or citation.

Q: Is it part of a series?

A: Yes — ISO 10307 has at least Part 1 (hot filtration) and Part 2 (standard ageing procedures, ISO 10307‑2:2009); the two parts are used together when assessing potential sediment formation after accelerated ageing.
