1.1 本标准为电接触应用中以带材、棒材、线材和零件形式生产的银锡氧化物材料的用户和制造商提供了指南。 1.2 银氧化锡是指含有银、氧化锡和其他金属氧化物的接触材料，可用于改善材料的加工或性能。 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熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，建立适当的安全、健康和环境实践，并在使用前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====== 4.1 这些材料的制造方法（专利或其他）因供应商而异，这些方法会影响电弧侵蚀、接触电阻和在役焊接倾向等特性。由于设备中触点的性能取决于触点本身以外的许多因素（打开速度、关闭速度、触点压力、触点反弹、环境变化、装配技术和变化等），因此本指南无法确保应用中的性能控制。作为初始样品鉴定的一部分，建议用户以功能方式对适用于材料使用的所有设备的材料进行电气测试。本指南将为触点制造商和触点用户提供一种方法，以就特定用途的材料细节达成协议，以及如何合理保证未来批次的性能和微观结构与所提供样品触点的初始测试相似。

1.1 This standard provides guidelines for users and manufacturers of silver-tin oxide material produced in strip, rod, wire, and part form for electrical contact applications. 1.2 Silver-tin oxide refers to contact material containing silver, tin oxide, and other metal oxide which may be used for either improving the processing or performance of the material. 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, 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 ====== 4.1 The methods for manufacture (proprietary or otherwise) of these materials vary significantly among suppliers, and these methods influence such properties as arc erosion, contact resistance, and tendency to weld in service. Since the performance of contacts in a device depends on numerous factors outside the contact itself (opening speed, closing speed, contact pressure, contact bounce, environmental variations, assembly technique and variations, etc.) this guide cannot ensure performance control in the application. As part of the qualification on initial samples it is recommended that the user electrically test the materials in a functional manner for all devices applicable to the material’s use. This guide will provide a means for the contact manufacturer and contact user to reach agreement on the details of material to be supplied for a specific use and how to provide reasonable assurance that future lots will be similar in properties and microstructure to the initial test of sample contacts supplied.
