1.1 本规程涵盖了波长色散X射线光谱仪的组件，这些组件对其操作和性能质量至关重要。本规程的目的不是指定部件公差或性能标准，因为这些标准对于每个仪器都是唯一的。然而，该实践确实试图确定哪些公差是关键的，因此哪些公差应予以规定。 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。 第节给出了具体的安全危害说明 7. . 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 本规程描述了波长色散X射线光谱仪的基本部件。提供此描述是为了让用户对X的结构有一个大致的了解- 射线光谱仪系统。它还提供了一种比较和评估不同系统以及了解每个仪器的功能和局限性的方法。 4.2 实验室可与分析仪器制造商合作实施本规程或X射线荧光法。如果实验室选择咨询仪器制造商，则应考虑以下事项。实验室应了解待分析的合金基体、待确定的元素和质量分数范围，以及每种元素的预期性能要求。 实验室应将这些要求告知仪器制造商，以便制定符合实验室期望的分析方法。通常，仪器制造商定制仪器配置，以满足终端用户对元素覆盖、元素精度和检测极限的要求。仪器制造商开发的分析方法可能包括样品激发、波长、元件间干扰校正、校准和回归、设备配置/安装以及样品制备要求的特定参数。 实验室应基本了解制造商得出的参数。

1.1 This practice covers the components of a wavelength dispersive X-ray spectrometer that are basic to its operation and to the quality of its performance. It is not the intent of this practice to specify component tolerances or performance criteria, as these are unique for each instrument. However, the practice does attempt to identify which tolerances are critical and thus which should be specified. 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 safety hazard statements are given in Section 7 . 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 a wavelength dispersive X-ray spectrometer. This description is presented so that the user may gain a general understanding of the structure of an X-ray spectrometer system. It also provides a means for comparing and evaluating different systems as well as understanding the capabilities and limitations of each instrument. 4.2 A laboratory may implement this practice or an X-ray fluorescence method in partnership with a manufacturer of the analytical instrumentation. If a laboratory chooses to consult with an instrument manufacturer, then the following should be considered. The laboratory should know the alloy matrices to be analyzed, elements and mass fraction ranges to be determined, and the expected performance requirements for each of these elements. The laboratory should inform the instrument manufacturer of these requirements so an analytical method may be developed which meets the laboratory’s expectations. Typically, instrument manufacturers customize the instrument configuration to satisfy the end-user’s requirements for elemental coverage, elemental precision, and detection limits. Instrument manufacturer developed analytical methods may include specific parameters for sample excitation, wavelengths, inter-element interference corrections, calibration and regression, equipment configuration/installation, and sample preparation requirements. Laboratories should have a basic understanding of the parameters derived by the manufacturer.
