Standard Test Method for Calibration and Accuracy Verification of Wideband Infrared Thermometers 宽带红外测温仪的校准和精度验证的标准测试方法
发布日期: 2013-05-01
1.1本试验方法涵盖通过检测测量对象和传感器之间交换的热辐射强度来测量温度的电子仪器。 1.2本试验方法涵盖的装置在本文件中称为红外温度计。 1.3本试验方法中涵盖的红外温度计是用于测量低于1000°C的温度、测量红外区域宽带上的热辐射以及直接读取温度的仪器。 1.4本指南涵盖了校准红外温度计的最佳实践。 它解决了有助于用户执行更准确校准的问题。它还提供了一种结构,用于计算不确定性和报告校准结果,以包括不确定性。 1.5本试验方法不包括红外温度计的设计和构造细节。 1.6本试验方法不包括1000°C以上的红外测温。它不涉及窄带红外温度计或不直接指示温度的红外温度计的使用。 1.7以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.8 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换,仅供参考,不被视为标准值。 ====意义和用途====== 5.1本指南提供了红外温度计精度验证的指南和基本测试方法。它包括测试设置和不确定性计算。它旨在为用户提供一致的方法,同时在选择校准设备时保持灵活性。据了解,获得的不确定度在很大程度上取决于所使用的仪器和仪表。 因此,由于本指南在方法上没有规定,它提供了不确定度评估的详细说明,以适应可能使用的各种仪器和仪表。 5.2本指南主要用于校准手持式红外温度计。然而,本指南中描述的技术也适用于校准其他类别的辐射温度计。这也可能有助于校准热成像仪。 5.3本指南规定了红外温度计校准报告的必要元素。所需元件旨在作为通信工具,帮助这些仪器的最终用户进行准确测量。 这些元件还提供了足够的信息,因此可以在单独的实验室中复制校准结果。
1.1 This test method covers electronic instruments intended for measurement of temperature by detecting the intensity of thermal radiation exchanged between the subject of measurement and the sensor. 1.2 The devices covered by this test method are referred to as infrared thermometers in this document. 1.3 The infrared thermometers covered in this test method are instruments that are intended to measure temperatures below 1000°C, measure thermal radiation over a wide bandwidth in the infrared region, and are direct-reading in temperature. 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. 1.5 Details on the design and construction of infrared thermometers are not covered in this test method. 1.6 This test method does not cover infrared thermometry above 1000°C. It does not address the use of narrowband infrared thermometers or infrared thermometers that do not indicate temperature directly. 1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. ====== Significance And Use ====== 5.1 This guide provides guidelines and basic test methods for the accuracy verification of infrared thermometers. It includes test set-up and calculation of uncertainties. It is intended to provide the user with a consistent method, while remaining flexible in the choice of calibration equipment. It is understood that the uncertainty obtained depends in large part upon the apparatus and instrumentation used. Therefore, since this guide is not prescriptive in approach, it provides detailed instruction in uncertainty evaluation to accommodate the variety of apparatus and instrumentation that may be employed. 5.2 This guide is intended primarily for calibrating handheld infrared thermometers. However, the techniques described in this guide may also be appropriate for calibrating other classes of radiation thermometers. It may also be of help to those calibrating thermal imagers. 5.3 This guide specifies the necessary elements of the report of calibration for an infrared thermometer. The required elements are intended as a communication tool to help the end user of these instruments make accurate measurements. The elements also provide enough information, so that the results of the calibration can be reproduced in a separate laboratory.
