(Practice)Standard Practice for Location of Wet Insulation in Roofing Systems Using Infrared Imaging
Standard Practice for Location of Wet Insulation in Roofing Systems Using Infrared Imaging
SIGNIFICANCE AND USE
4.1 This practice is used to outline the minimum necessary elements and conditions to obtain an accurate determination of the location of wet insulation in roofing systems using infrared imaging.
4.2 This practice is not meant to be an instructional document or to provide all the knowledge and background necessary to provide an accurate analysis. For further information, see ANSI-ASHRAE Standard 101 and ISO/DP 6781.3E.
4.3 This practice does not provide methods to determine the cause of moisture or its point of entry. It does not address the suitability of any particular system to function capably as waterproofing.
SCOPE
1.1 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 ground-based inspections are being conducted.)
1.2 This practice addresses criteria for infrared equipment such as minimum resolvable temperature difference, spectral range, instantaneous field of view, and field of view.
1.3 This practice addresses meteorological conditions under which infrared inspections shall be performed.
1.4 This practice addresses the effect of roof construction, material differences, and roof conditions on infrared inspections.
1.5 This practice addresses operating procedures, operator qualifications, and operating practices.
1.6 This practice also addresses verification of infrared data using invasive test methods.
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.8 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 1.1.
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
