ASTM E2847-11<\/h3>\n

Historical Standard: Standard Practice for \ufeff \ufeffCalibration and Accuracy Verification of Wideband Infrared Thermometers<\/h4>\n
\n

ASTM E2847<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This guide covers electronic instruments intended for measurement of temperature by detecting the intensity of thermal radiation exchanged between the subject of measurement and the sensor.<\/p>\n

1.2 The devices covered by this guide are referred to as infrared thermometers in this document.<\/p>\n

1.3 The infrared thermometers covered in this guide are instruments that are intended to measure temperatures below 1000\u00b0<\/span>C, measure thermal radiation over a wide bandwidth in the infrared region, and are direct-reading in temperature.<\/p>\n

1.4 This guide covers best practice in calibrating infrared thermometers. It addresses concerns that will help the user perform more accurate calibrations. It also provides a structure for calculation of uncertainties and reporting of calibration results to include uncertainty.<\/p>\n

1.5 Details on the design and construction of infrared thermometers are not covered in this guide.<\/p>\n

1.6 This guide does not cover infrared thermometry above 1000\u00b0<\/span>C. It does not address the use of narrowband infrared thermometers or infrared thermometers that do not indicate temperature directly.<\/p>\n

1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.<\/p>\n

1.8 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.<\/span><\/p>\n
