Imaging materials -- Photographic reflection prints -- Methods for measuring indoor light stability
This document describes test equipment and procedures for measuring the light stability of colour photographic reflection prints designed for display, when subjected to a filtered xenon-arc light source simulating daylight through windows at specified temperatures and relative humidity. This document is applicable to photographic reflection prints, made with analogue and digital print processes. The recommended test methods can be applied to both colour and black-and-white photographic prints. This test method assesses colour and density change.

Optics and photonics -- Optical transfer function -- Application -- Part 3: Telescopes
This document specifies a method of testing telescopes in terms of imaging states aimed at making valid optical transfer function (OTF) measurements. This document includes two annexes (Annex A and B) that provide information on the more recent techniques for measuring optical transfer function and methods of deriving image quality criteria from such measurements.
