BS 5699-1:1979, ISO 4331-1977

Overview

BS 5699-1:1979, aligned with ISO 4331-1977, specifies the requirements for processed photographic film intended for archival records. This standard focuses on silver-gelatin type films that are manufactured on a cellulose ester base. The primary aim is to ensure that the photographic films meet specific quality and durability standards suitable for long-term storage and archival purposes.

Key Requirements

The standard outlines several critical parameters that must be adhered to in the production and processing of silver-gelatin photographic films. These include:

• Film Composition: The film must be composed of a silver-gelatin emulsion coated on a cellulose ester base, ensuring compatibility with archival storage conditions.
• Image Stability: Films must demonstrate high levels of image stability under various environmental conditions, including temperature and humidity fluctuations.
• Physical Characteristics: The standard specifies requirements for the physical properties of the film, including thickness, flexibility, and resistance to tearing.
• Processing Standards: Guidelines for the processing of the film are included to ensure that the final product meets the necessary archival quality.

Implementation Benefits

Adhering to BS 5699-1:1979 provides numerous benefits for organisations involved in the production, processing, and archiving of photographic materials. These benefits include:

• Quality Assurance: Compliance with this standard ensures that the photographic films produced are of high quality, suitable for long-term preservation.
• Standardisation: The standard promotes uniformity in production processes, which can enhance operational efficiency and reduce variability in product quality.
• Enhanced Longevity: By following the specifications, organisations can produce films that are more resilient to degradation, ensuring that archival records remain accessible for future generations.
• Market Competitiveness: Compliance with recognised standards can improve marketability and customer trust, as clients often seek assurance of quality and reliability in archival materials.

Compliance Value

Compliance with BS 5699-1:1979 is essential for organisations that aim to maintain high standards in archival practices. Meeting these specifications not only demonstrates a commitment to quality but also mitigates risks associated with the deterioration of photographic records. Key compliance advantages include:

• Regulatory Adherence: Many archival institutions and government bodies require compliance with established standards, making adherence to BS 5699-1:1979 a prerequisite for acceptance.
• Risk Management: By ensuring that photographic films meet stringent quality criteria, organisations can reduce the risk of loss or damage to valuable archival materials.
• Documentation and Traceability: The standard encourages thorough documentation of processes and materials, facilitating traceability and accountability in archival practices.

In conclusion, BS 5699-1:1979 serves as a vital framework for the production and processing of silver-gelatin photographic films on cellulose ester bases. By adhering to its specifications, organisations can ensure the longevity and quality of their archival records, ultimately contributing to the preservation of cultural and historical heritage.
