Описание (английский):

This International Standard specifies the methods for determining the maximum exposure time that a given sensitized material can receive from a given safelight without affecting the quality of the final image. It also specifies the records which shall be maintained for the components of a safelight and its operating environment.

Abstract

Overview

Key Topics

Safelight Exposure Limits: Methods for establishing the maximum exposure duration for different sensitized materials when exposed to various safelight types.
Test Methods: Two main procedures (Method 1 and Method 2) for evaluating the safelight’s effect on photographic materials, addressing both unknown and known safelight/material relationships.
Evaluation Techniques: Both subjective (visual) and objective (instrumental) methods for detecting the smallest change in image density or hue due to safelight exposure.
Record Keeping: Requirements for maintaining detailed records on safelight fixtures, light sources, filters, distances, environmental conditions, and usage history.
Safelight Components: Definitions related to safelights, such as safelight filters, fixtures, irradiance, and safetime.
Testing in Processing: Procedures for testing safelight sensitivity during various stages of photographic processing.
Half-Tone Image Testing: Annex for testing safelight effects specifically on half-tone images to address high-contrast materials used in graphic arts.

Applications

SIST ISO 8374:2003 is applicable across a range of photography and imaging environments where sensitized materials are handled under safelight conditions. Its practical applications include:

Photographic Laboratories: Ensuring darkroom safelight conditions do not impact film or paper during printing, processing, or inspection.
Manufacturing Environments: Defining safe handling protocols for photographic films and papers during production, packaging, and quality control.
Graphic Arts: Assessing safelight exposure effects on high-contrast, half-tone materials used in printing and publishing.
Medical Imaging: Verifying safe lighting in darkrooms where radiographic or X-ray films are processed and handled.
Safelight Design: Providing manufacturers and suppliers with standardized criteria for the development and specification of safelight products and fixtures.
Maintenance and Compliance: Supporting darkroom staff in maintaining consistent safelight conditions, tracking lamp/filter aging, and verifying that changes to the environment remain within safe limits.

Applying the standard helps prevent fogging, density shifts, image degradation, and ensures repeatable photographic results, especially in high-precision or archival applications.
