ICS Code (Components for aerospace construction): 49.035
significance And Use:

One of the measures of optical quality of a transparent part is its angular deviation. Excessive angular deviation, or variations in angular deviation throughout the part, result in visible... View More

scope:

1.1 This test method covers measuring the angular deviation of a light ray imposed by transparent parts such as aircraft windscreens and canopies. The results are uncontaminated by the effects of lateral displacement, and the procedure may be performed in a relatively short optical path length. This is not intended as a referee standard. It is one convenient method for measuring angular deviations through transparent windows.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
