1.1 This guide covers electronic instruments intended for measurement of temperature by detecting intensity of thermal radiation exchanged between the subject of measurement and the sensor. 1.2 The devices covered by this guide are referred to as IR thermometers. 1.3 The IR thermometers covered in this guide are instruments that are intended to measure temperatures below 2700 °C and measure a narrow to wide band of thermal radiation in the infrared region. 1.4 This guide covers best practice in using IR thermometers. It addresses concerns that will help the user make better measurements. It also provides graphical tables to help determine the accuracy of measurements. 1.5 Details on the design and construction of IR thermometers are not covered in this guide. 1.6 This guide addresses general information on emissivity and how to deal with emissivity when making measurements with an IR thermometer. 1.7 This guide contains basic information on the classification of different types of IR thermometers. 1.8 The values of quantities stated in SI units are to be regarded as the standard. The values of quantities in parentheses are not in SI and are optional. 1.9 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. 1.10 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 guide provides guidelines and basic test methods for the use of infrared thermometers. The purpose of this guide is to provide a basis for users of IR thermometers to make more accurate measurements, to understand the error in measurements, and reduce the error in measurements.
