ASTM G130-2020适用范围

1.1 This test method covers the calibration of ultraviolet light-measuring radiometers possessing either narrow- or broad-band spectral response distributions using either a scanning or a linear-diode-array spectroradiometer as the primary reference instrument. For transfer of calibration from radiometers calibrated by this test method to other instruments, Test Method E824 should be used.

NOTE 1:Special precautions must be taken when a diode-array spectroradiometer is employed in the calibration of filter radiometers having spectral response distributions below 320-nm wavelength. Such precautions are described in detail in subsequent sections of this test method.

1.2 This test method is limited to calibrations of radiometers against light sources that the radiometers will be used to measure during field use.

NOTE 2:For example, an ultraviolet radiometer calibrated against natural sunlight cannot be employed to measure the total ultraviolet irradiance of a fluorescent ultraviolet lamp.

1.3 Calibrations performed using this test method may be against natural sunlight, Xenon-arc burners, metal halide burners, tungsten and tungsten-halogen lamps, fluorescent lamps, etc.

1.4 Radiometers that may be calibrated by this test method include narrow-, broad-, and wide-band ultraviolet radiometers, and narrow-, broad, and wide-band visible-region-only radiometers, or radiometers having wavelength response distributions that fall into both the ultraviolet and visible regions.

NOTE 3:For purposes of this test method, narrow-band radiometers are those with Δλ ≤ 20 nm, broad-band radiometers are those with 20 nm ≤Δλ ≤ 70 nm, and wide-band radiometers are those with Δλ ≥ 70 nm.

NOTE 4:For purposes of this test method, the ultraviolet region is defined as the region from 285 to 400-nm wavelength, and the visible region is defined as the region from 400 to 750-nm wavelength. The ultraviolet region is further defined as being either UV-A with radiation of wavelengths from 315 to 400 nm, or UV-B with radiation from 285 to 315-nm wavelength.

1.5 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.

1.6 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.

1.1本试验方法包括使用扫描或线性二极管阵列光谱辐射计作为主要参考仪器，对具有窄带或宽带光谱响应分布的紫外线测量辐射计进行校准。为了将通过本试验方法校准的辐射计的校准转移到其他仪器，应使用试验方法E824。

注1：当二极管阵列光谱辐射计用于校准光谱响应分布低于320 nm波长的滤波辐射计时，必须采取特殊预防措施。在本试验方法的后续章节中详细描述了此类预防措施。

1.2本试验方法仅限于针对现场使用期间辐射计将用于测量的光源对辐射计进行校准。

注2：例如，根据自然阳光校准的紫外线辐射计不能用于测量荧光紫外线灯的总紫外线辐照度。

1.3使用本试验方法进行的校准可针对自然阳光、氙弧燃烧器、金属卤化物燃烧器、钨和卤钨灯、荧光灯等进行。

1.4可通过本试验方法校准的辐射计包括窄带、宽带和宽带紫外辐射计，以及仅限窄带、宽带和宽带可见光区域的辐射计，或波长响应分布同时属于紫外和可见光区域的辐射计。

注3：就本试验方法而言，窄带辐射计为Δλ型≤ 20nm，宽带辐射计为20nm辐射计≤Δλ ≤ 70 nm，宽带辐射计为Δλ≥ 70纳米。

注4：在本试验方法中，紫外线区域定义为波长为285至400 nm的区域，可见光区域定义为波长为400至750 nm的区域。紫外线区域进一步定义为波长为315至400 nm的UV-A或波长为285至315 nm的UV-B。

1.5本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。

1.6本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。
