|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—Extreme caution shall 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
groundbased 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 shall be performed.
This practice addresses the effect of roof construction,
material differences, and roof conditions on infrared
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. No
other units of measurement are included in this standard.
