ISO/TS 18950 discusses imaging materials.
ISO/TS 18950 specifies test methods that are used to compare and characterize the degradation of a set of print materials that are exposed to light sources including indoor daylight, LED, and incandescent light under museum environmental conditions.
ISO/TS 18950 applies to analogue and digital reflection photographic prints and guides for assessing light exposure-related damage to analogue and digital photographic prints.
ISO/TS 18950 covers typical types of indoor light sources commonly found in a museum including indoor daylight, LED, and incandescent light.
Note 1: Under ISO/TS 18950 photographic prints made on black and white silver halide paper are not covered.
ISO/TS 18950 on the degradation of prints under museum conditions is relevant to:
Prints are used in museums for display in permanent or temporary exhibitions under ambient light. The quality of these prints deteriorates due to factors like heat, light, humidity and pollutants which in some way can be controlled by the museum but the light is necessary for display and can cause degradation over time. The choice of the light source with the lowest damage potential depends on the specific material type in the mix and the spectral irradiance of the light source.
Test methods under ISO/TS 18950 assist in selecting the lighting with the lowest possible damage potential for the museum.
ISO/TS 18950 guides on how to assess the light exposure-related damage to analogue and digital photographic prints under museum display conditions for particular print materials sets. ISO/TS 18950 assists in manufacturing lighting materials that can provide a one-time solutions for the museums.helps you in manufacturing lighting materials that can provide solution for the museums.
Efficient evaluation of the effect of light sources on the degradation of prints under museum conditions can be used for reducing damage by developing or choosing the appropriate and efficient light source for the museum.
It can also serve as a basis for the comparison between different lightning sources for the museum.
