Overview
ISO 10349-8:2002 - part of the ISO 10349 series - specifies a general test method for the determination of volatile matter in photographic‑grade chemicals. The standard provides a repeatable gravimetric procedure (oven drying and weighing) to quantify mass loss due to volatile components. It is intended for use with photographic chemicals where control of volatile matter affects product stability, performance and safety.
Key topics and requirements
- Scope and normative references
- Relies on ISO 10349-1 for general provisions on reagents, glassware, hazards and sampling.
- Apparatus (examples specified)
- Low‑form, glass‑stoppered weighing bottle (50 ml capacity).
- Oven capable of maintaining temperatures in the range 70 °C to 150 °C.
- Analytical balance with high precision (example accuracy indicated in the standard).
- Desiccator with suitable desiccant for cooling samples to room temperature before weighing.
- Procedure (general)
- Weigh a specified test portion into a dried weighing bottle.
- Dry the sample in the oven at the temperature and for the time specified for the particular material (see the appropriate International Standard or product method).
- Cool in a desiccator to room temperature and reweigh to the precision required.
- Calculation
- Express volatile matter as a percentage by mass: determine the mass loss on drying (mass before drying minus mass after drying) divided by the initial sample mass (mass before drying minus mass of the empty bottle), multiplied by 100.
- Test reporting
- Report the method used, test result and all operating details not specified in ISO 10349‑8 (e.g., drying temperature/time used), any incidents affecting results, and full sample identification.
Applications and users
- Who uses it
- Quality control and analytical laboratories in photographic and imaging chemical manufacturing.
- Raw material inspectors, R&D chemists developing photographic formulations, and regulatory/compliance personnel overseeing product specifications.
- Why it matters
- Controls volatile impurities that can affect chemical stability, image quality, shelf life and worker/environmental safety.
- Provides a standard, reproducible method for contract testing, supplier qualification and batch release.
Related standards
- ISO 10349-1:2002 (General) and other parts of ISO 10349 covering insoluble matter, heavy metals, halide content, pH, density and related test methods for photographic‑grade chemicals.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodi
