ASTM G130-2020適用范圍

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本試驗方法包括使用掃描或線性二極管陣列光譜輻射計作為主要參考儀器，對具有窄帶或?qū)拵Ч庾V響應(yīng)分布的紫外線測量輻射計進行校準。為了將通過本試驗方法校準的輻射計的校準轉(zhuǎn)移到其他儀器，應(yīng)使用試驗方法E824。

注1：當二極管陣列光譜輻射計用于校準光譜響應(yīng)分布低于320 nm波長的濾波輻射計時，必須采取特殊預(yù)防措施。在本試驗方法的后續(xù)章節(jié)中詳細描述了此類預(yù)防措施。

1.2本試驗方法僅限于針對現(xiàn)場使用期間輻射計將用于測量的光源對輻射計進行校準。

注2：例如，根據(jù)自然陽光校準的紫外線輻射計不能用于測量熒光紫外線燈的總紫外線輻照度。

1.3使用本試驗方法進行的校準可針對自然陽光、氙弧燃燒器、金屬鹵化物燃燒器、鎢和鹵鎢燈、熒光燈等進行。

1.4可通過本試驗方法校準的輻射計包括窄帶、寬帶和寬帶紫外輻射計，以及僅限窄帶、寬帶和寬帶可見光區(qū)域的輻射計，或波長響應(yīng)分布同時屬于紫外和可見光區(qū)域的輻射計。

注3：就本試驗方法而言，窄帶輻射計為Δλ型≤ 20nm，寬帶輻射計為20nm輻射計≤Δλ ≤ 70 nm，寬帶輻射計為Δλ≥ 70納米。

注4：在本試驗方法中，紫外線區(qū)域定義為波長為285至400 nm的區(qū)域，可見光區(qū)域定義為波長為400至750 nm的區(qū)域。紫外線區(qū)域進一步定義為波長為315至400 nm的UV-A或波長為285至315 nm的UV-B。

1.5本標準并非旨在解決與其使用相關(guān)的所有安全問題（如有）。本標準的使用者有責任在使用前建立適當?shù)陌踩?、健康和環(huán)境實踐，并確定監(jiān)管限制的適用性。

1.6本國際標準是根據(jù)世界貿(mào)易組織技術(shù)性貿(mào)易壁壘（TBT）委員會發(fā)布的《關(guān)于制定國際標準、指南和建議的原則的決定》中確立的國際公認標準化原則制定的。
