Standard Practice for Polarized Light Detection of Flaws in Aerospace Transparency Heating Elements
 N F319

Annotation

This practice covers a standard procedure for detecting flaws in the conductive coating (heater element) by the observation of polarized light patterns.

This practice applies to coatings on surfaces of monolithic transparencies as well as to coatings imbedded in laminated structures.

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

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. For specific precautionary statements.
