1.1 该实践适用于在夜间使用红外成像来确定屋顶系统中湿隔热层的位置的技术，该屋顶系统在甲板上方具有与防水层接触的隔热层。这种做法包括地面和空中检查。( 警告-- 进入或在屋顶表面行走时，以及在低空操作飞机时，尤其是在夜间，应格外小心。）( 警告-- 在进行地面检查时，至少有两个人始终在屋顶表面，这是一种良好的安全做法。） 1.2 该实践涉及红外设备的标准，如最小可分辨温差、光谱范围、瞬时视场和视场。 1.3 本规程针对应进行红外检查的气象条件。 1.4 该实践解决了屋顶结构、材料差异和屋顶条件对红外检测的影响。 1.5 本规程涉及操作程序、操作员资格和操作规程。 1.6 该实践还涉及使用侵入性测试方法验证红外数据。 1.7 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.8 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 中给出了具体的预防说明 1.1 。 1.9 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 4.1 该实践用于概述使用红外成像准确确定屋顶系统中湿绝缘位置所需的最低要素和条件。 4.2 这种做法并不意味着是一份指导性文件，也不意味着提供提供准确分析所需的所有知识和背景。有关详细信息，请参见ANSI-ASHRAE标准 101和ISO/DP 6781.3E。 4.3 本规程未提供确定湿气原因或湿气进入点的方法。它没有说明任何特定系统是否适合用作防水材料。

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. ====== 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.
