Standard Test Method for Measuring Optical Angular Deviation of Transparent Parts Using the Double-Exposure Method
 N F2469

Annotation

This test method covers the measurement of the optical angular deviation of a light ray imposed by flat transparent parts such as a commercial or military aircraft windshield, canopy, or cabin window.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Exceptions—The values given in parentheses are for information only. Also, print size is provided in inch-pound measurements.

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.
