1.1本规程涵盖了分光光度性能要求的描述，尤其是ASTM方法的要求，以及测试特定方法可用设备的充分性。测试给出了控制分光光度法结果的一些重要参数的测量结果，但具体来说，不能得出仪器性能中的所有因素都是测量的结论。 1.1.1不得使用本惯例( 1. )作为对仪器性能的严格测试，或( 2. )比较不同设计仪器的定量性能。 1.1.2本规程主要针对用于透射率测量的色散分光光度计，而不是用于漫透射和漫反射的仪器。 ====意义和用途====== 这种做法允许分析员在特定分光光度法中使用仪器时，将其一般性能与开发该方法时使用的仪器性能进行比较。

1.1 This practice covers the description of requirements of spectrophotometric performance especially for ASTM methods, and the testing of the adequacy of available equipment for a specific method. The tests give a measurement of some of the important parameters controlling results obtained in spectrophotometric methods, but it is specifically not to be concluded that all the factors in instrument performance are measured. 1.1.1 This practice is not to be used ( 1 ) as a rigorous test of performance of instrumentation, or ( 2 ) to intercompare the quantitative performance of instruments of different design. 1.1.2 This practice is primarily directed to dispersive spectrophotometers used for transmittance measurements rather than instruments designed for diffuse transmission and diffuse reflection. ====== Significance And Use ====== This practice permits an analyst to compare the general performance of his instrument, as he is using it in a specific spectrophotometric method, with the performance of instruments used in developing the method.
