1.1 这些测试方法中描述的测试方法可用于评估辐射温度计（单波段类型）的以下六个基本操作参数: 部分 校准精度 8. 重复性 9 视野 10 响应时间 11 预热时间 12 长期稳定性 13 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 1.3 术语单波段是指在单波段光谱辐射中工作的辐射温度计。该术语用于区分单波段辐射温度计与比值辐射温度计、双通道辐射温度计、双色辐射温度计、多波长辐射温度计、多通道辐射温度计或多色辐射温度计。术语“单波段”并不排除宽带辐射温度计，例如在8–14μm波段工作的辐射温度计。 ====意义和用途====== 4.1 这些测试方法的目的是建立一致的测试方法，制造商和最终用户可以通过这些方法进行测试，以确定其辐射温度计读数的有效性。测试结果也可以作为仪器评估或选择的标准性能标准，或两者兼而有之。 4.2 目标是提供可靠的测试方法，并且可以由足够熟练的最终用户或制造商执行。希望这将有助于更好地了解辐射温度计的操作，并促进制造商和最终用户之间更好的沟通。 没有足够知识和经验的用户应寻求设备制造商或其他专家的帮助，例如马里兰州盖瑟斯堡国家标准与技术研究所的专家。 4.3 使用这些测试方法时，应意识到还有其他参数，特别是光谱范围限制和温度分辨率，这些参数会影响辐射温度计的使用和表征，并且尚未制定测试方法。 4.3.1 温度分辨率是目标温度的最小模拟或实际变化，导致输出或指示或两者的可用变化。 它通常表示为温差或满标度值的百分比，或两者兼有，通常适用于测量值。温度分辨率的大小取决于四个因素的组合:探测器噪声等效温差（NETD）、电子信号处理、信噪比特性（包括放大噪声）和模数转换“粒度” 4.3.2 光谱范围限制是指仪器响应的辐射能波段的上限和下限。这些极限通常以微米（μm）表示，并包括测量光路中所有元件的影响。 在光谱响应极限下，测量光学器件的透射比为5 % 峰值传输。（参见 图1 .)

1.1 The test methods described in these test methods can be utilized to evaluate the following six basic operational parameters of a radiation thermometer (single waveband type): Section Calibration Accuracy 8 Repeatability 9 Field-of-View 10 Response Time 11 Warm-Up Time 12 Long-Term Stability 13 1.2 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. 1.3 The term single waveband refers to radiation thermometers that operate in a single band of spectral radiation. This term is used to differentiate single waveband radiation thermometers from those termed as ratio radiation thermometers, two channel radiation thermometers, two color radiation thermometers, multiwavelength radiation thermometers, multichannel radiation thermometers, or multicolor radiation thermometers. The term single waveband does not preclude wideband radiation thermometers such as those operating in the 8 – 14 μm band. ====== Significance And Use ====== 4.1 The purpose of these test methods is to establish consensus test methods by which both manufacturers and end users may perform tests to establish the validity of the readings of their radiation thermometers. The test results can also serve as standard performance criteria for instrument evaluation or selection, or both. 4.2 The goal is to provide test methods that are reliable and can be performed by a sufficiently skilled end user or manufacturer. It is hoped that it will result in a better understanding of the operation of radiation thermometers and also promote improved communication between the manufacturers and the end users. A user without sufficient knowledge and experience should seek assistance from the equipment makers or other expert sources, such as those found at the National Institute of Standards and Technology in Gaithersburg, Maryland. 4.3 These test methods should be used with the awareness that there are other parameters, particularly spectral range limits and temperature resolution, which impact the use and characterization of radiation thermometers and for which test methods have not yet been developed. 4.3.1 Temperature resolution is the minimum simulated or actual change in target temperature that results in a usable change in output or indication, or both. It is usually expressed as a temperature differential or a percent of full-scale value, or both, and usually applies to value measured. The magnitude of the temperature resolution depends upon a combination of four factors: detector noise equivalent temperature difference (NETD), electronic signal processing, signal-to-noise characteristics (including amplification noise), and analog-to-digital conversion “granularity.” 4.3.2 Spectral range limits are the upper and lower limits to the wavelength band of radiant energy to which the instrument responds. These limits are generally expressed in micrometers (μm) and include the effects of all elements in the measuring optical path. At the spectral response limits, the transmission of the measuring optics is 5 % of peak transmission. (See Fig. 1 .)
