Scope

This part of ISO 18937 describes test methods for measuring the light stability of photographic prints when subjected to LED illumination sources under conditions that simulate indoor display.

This document is applicable to all types of colour and monochrome photographic prints. It applies to reflection prints, transparent and translucent films.

This document does not include test procedures for determining the effects of light exposure on the physical stability of images, supports, or binder materials.

NOTE 1 It is recognized that in some instances, physical degradation such as support embrittlement, image layer cracking, or delamination of an image layer from its support, rather than the stability of the image itself, will determine the useful life of a print material.

NOTE 2 General guidance and requirements are given in ISO 18937-1.
