1.1 本规程描述了直流等离子体（DCP）原子发射光谱仪的组件。这种做法并不试图指定组件公差或性能标准。但是，这种做法确实试图确定影响偏差、精度和灵敏度的关键因素。在下订单之前，潜在用户应咨询制造商，以设计测试协议，证明仪器满足所有预期需求。 1.2 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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。 第节给出了具体的危害声明 9 . 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 4.1 本规程描述了DCP光谱仪的基本部件。此描述允许用户或潜在用户对该系统有基本的了解。它还提供了一种将该系统与类似系统进行比较和评估的方法，以及了解每种仪器的功能和局限性的方法。

1.1 This practice describes the components of a direct current plasma (DCP) atomic emission spectrometer. This practice does not attempt to specify component tolerances or performance criteria. This practice does, however, attempt to identify critical factors affecting bias, precision, and sensitivity. Before placing an order a prospective user should consult with the manufacturer to design a testing protocol for demonstrating that the instrument meets all anticipated needs. 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. Specific hazards statements are give in Section 9 . 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 ====== 4.1 This practice describes the essential components of the DCP spectrometer. This description allows the user or potential user to gain a basic understanding of this system. It also provides a means of comparing and evaluating this system with similar systems, as well as understanding the capabilities and limitations of each instrument.
