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 1000 °C and measure a 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 does not cover medium- and high-temperature IR thermometry (above 1000 °C). It does not address the use of narrowband IR thermometers. 1.7 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. 1.8 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== 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.
