Status: historical
Page Count: 3
ICS Code (Aerospace electric equipment and systems): 49.060
scope:

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

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

1.3 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, see Section 6.

1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
