This document specifies test equipment and test procedures for determination of the following optical characteristics of telescopic sights:

— axial parallax;

— parallax;

— eye relief range, eye relief, critical eye relief;

— reticle tracking;

— line of sight shift due to zooming;

— line of sight shift due to focusing.
