This Technical Report applies to all forms of silver-gelatin microfilm, whether in roll, aperture card, jacket or microfiche format. It describes the equipment and procedures necessary to identify and monitor deterioration. This information serves to identify the extent and nature of the problem and will ultimately provide a sound basis for any remedial action that may be required.

Overview

ISO/TR 12031:2000 - "Micrographics - Inspection of silver‑gelatin microforms for evidence of deterioration" is an informative Technical Report from ISO that establishes a uniform approach for selecting, inspecting and monitoring silver‑gelatin microfilm. It applies to all formats (roll film, aperture cards, jackets and microfiche) and describes the equipment, environmental conditions and procedures needed to identify deterioration and support subsequent remedial action and preservation planning.

Key topics and technical requirements

Scope and formats: Applies to all silver‑gelatin microforms (16 mm, 35 mm, microfiche, jackets, aperture cards).

Inspection environment: Clean, low‑dust room; recommended maximum temperature 23 °C and relative humidity 50% during inspection; avoid rapid changes in climate.

Equipment and supplies: Light box with translucent cover (fluorescent, tungsten or tungsten‑halogen acceptable), film rewinds, eye loupes (~5× and 15×), microscope (at least 25× and 50×), specular light source for surface inspection, black velvet background, and clean lint‑free inspection gloves (white cotton or nylon).

Sampling and grouping: Prefer full inspection where feasible; otherwise use representative sampling per ISO 2859 sampling procedures. Divide collections into survey groups by film type, storage conditions, date or record series for meaningful analysis.

Inspection procedures: Examine both sides of the film, use magnification and alternate lighting to detect surface defects, and follow documented steps to record findings.

Defect types to detect: Microbiological growth, redox blemishes (silver oxidation), residual processing chemicals, emulsion adhesion problems, emulsion/base separation (frilling), brittleness and base shrinkage.

Reporting and analysis: Classify defects, record group and individual microform histories, and optionally analyze data to prioritize conservation or remediation.

Remedial action: The report provides a basis for identifying extent and nature of deterioration to inform conservation decisions (detailed remediation techniques are outside the scope of this summary).

Applications and users

Archives, libraries and museums managing microform collections

Records management and legal/financial repositories relying on microfilm retention

Conservation and preservation specialists

Micrographics labs and digitization project teams

Facilities planning storage, monitoring and disaster‑avoidance for legacy film assets

Using this standard helps organizations detect early deterioration, prioritize preservation resources, and support digitization or remediation strategies.
