1.1 本规程涵盖了机架上电镀零件的设计信息。本文中包含的建议不是强制性的，但旨在为良好实践提供指导。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 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。 1.4 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====== 2.1 在对物品进行电镀时，不仅需要考虑电镀工艺的特点，还需要考虑零件的设计，以最大限度地减少电镀和表面处理成本和溶液排放，并改善外观和功能。 在设计和工程阶段，通常可以对形状进行小的调整，从而以较低的成本获得较高质量的零件。 2.2 电镀工艺的特性是电镀溶液的分散能力，需要注意可选设计的细节。这一术语描述了溶液的性质，因为它与阴极的溶液电阻和溶液电容以及电解质系统的整体效率有关。投掷功率是指在特定条件下，在给定溶液中，相对于电极（通常是阴极）上的一次电流分布，涂层分布的改善。

1.1 This practice covers design information for parts to be electroplated on racks. The recommendations contained herein are not mandatory, but are intended to give guidance toward good practice. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. 1.4 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 ====== 2.1 When an article is to be electroplated, it is necessary to consider not only the characteristics of the electroplating process, but also the design of the part to minimize electroplating and finishing costs and solution dragout as well as to improve appearance and functionality. It is often possible during the design and engineering stages to make small adjustments in shape that will result in considerable benefit toward a better quality part at a lower cost. 2.2 The specific property of an electroplating process that would require some attention to the details of optional designs, is the throwing power of the electroplating solution. This term describes the properties of the solution as it relates to the solution electrical resistance and solution capacitance at the cathode and overall efficiency of the electrolyte system. Throwing power is defined as the improvement of the coating distribution over the primary current distribution on an electrode (usually cathode) in a given solution, under specified conditions.
