Imaging materials - Methods for measuring indoor light stability of photographic prints - Part 3: LED lamp exposure

ISO 18937-3:2026

This document 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 reflection prints.

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.

NOTE 3        Tables 1 and 3 of LED lamp relative spectral irradiance were created using spectra from phosphor-converted blue LED lamps. Other types of LED lamps that meet the criteria of Tables 1 and 3 are also in the scope of this document.
