1.1 本规程为建立和控制火花原子发射光谱化学分析曲线提供了方向。分析曲线的生成及其控制被视为独立但相互关联的操作。本规程适用于火花原子发射光谱仪。 注1: 本规程不再涵盖X射线荧光光谱测定应用。参见参考线 E1361 和 E1621 用于讨论此技术。 1.1.1 由于软件程序可用于计算可用于生成分析曲线的多元线性回归，并且由于大多数仪器都包含此功能，因此本实践不涉及此过程。然而，给出了一些建议来评估生成的方程。 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、健康和环境实践，并确定监管限制的适用性。 1.3 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。 ====意义和用途====== 5.1 本规程旨在为火花原子发射光谱仪分析曲线的校准、漂移校正和周期控制提供基本指导。 5.2 假设本规程将由能够执行本文所述程序的训练有素的操作员使用。

1.1 This practice provides direction for establishing and controlling spark atomic emission spectrochemical analytical curves. The generation of analytical curves and their control are considered as separate though interrelated operations. This practice is applicable to spark atomic emission spectrometers. Note 1: X-ray fluorescence spectrometric applications are no longer covered by this practice. See Guides E1361 and E1621 for discussion of this technique. 1.1.1 Since software programs are readily available to compute multiple linear regressions that can be used to generate analytical curves and since most instruments include this feature, this practice does not address this procedure. However, some recommendations are given to evaluate the equations that are generated. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 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. ====== Significance And Use ====== 5.1 This practice is intended to provide fundamental direction for the calibration, drift correction, and periodic control of the analytical curves for spark atomic emission spectrometers. 5.2 It is assumed that this practice will be used by trained operators capable of performing the procedures described herein.
