This practice applies to techniques that employ infrared imaging at night to determine the location of wet insulation in roofing systems that have insulation above the deck in contact with the waterproofing. This practice includes ground-based and aerial inspections. (Warning - Caution should be taken in handling any cryogenic liquids and pressurized gases required for use in this practice.) (Warning - Extreme caution should be taken when accessing or walking on roof surfaces and when operating aircraft at low altitudes, especially at night.) (Warning - It is a good safety practice for at least two people to be present on the roof surface at all times when ground-based inspections are being conducted.)

This practice addresses criteria for infrared equipment such as minimum resolvable temperature difference, spectral range, instantaneous field of view, and field of view.

This practice addresses meteorological conditions under which infrared inspections should be performed.

This practice addresses the effect of roof construction, material differences, and roof conditions on infrared inspections.

This practice addresses operating procedures, operator qualifications, and operating practices.

This practice also addresses verification of infrared data using invasive test methods.

The values stated in SI units are to be regarded as 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. Specific precautionary statements are given in 1.1.
