BS ISO 18949:2019

This standard BS ISO 18949:2019 Imaging materials. Reflection colour photographic prints. Method for testing stability under low humidity conditions is classified in these ICS categories:

• 37.040.20 Photographic paper, films and plates. Cartridges

This document describes test methods to evaluate reflection colour photographic prints with regard to changes in image appearance resulting from exposure to low relative humidity.

The observed changes relate primarily to substrate yellowing. Other observed humidity related physical damage factors such as curl, cockle, cracking, or delamination due to humidity cycling are also within the scope of this test method.
