标准摘要
[中文适用范围]： IEC 60747-5-13:2021+AMD1:2026 CSV 提供了一种加速测试方法，用于评估氢硫酸对用于LED封装的银及其合金的腐蚀（即“硫化”）所产生的影响。该测试方法旨在提供有关银及其合金腐蚀对LED封装光通量/辐射通量保持能力的影响信息。此外，该测试方法还可以提供由于银及其合金腐蚀导致的LED封装电性能变化的信息。本测试的目的是确定含硫化氢的大气对以下LED封装部件的影响：银或银合金；表面覆盖有其他层的银或银合金；表面覆盖有银或银合金的其他金属。本测试不适用于评估可能影响光通量/辐射通量保持能力及/或电性能的其他劣化现象（如铜或硅胶部件的劣化）。本测试可能不适合作为通用腐蚀测试方法，也就是说，它可能无法预测工业气氛中通量、电特性及连接件的行为。只有在被IEC SC 34A文件引用时，本文件才适用于照明应用的LED封装。 [外文原描述]： IEC 60747-5-13:2021+AMD1:2026 CSV provides the accelerated test method to assess effects of the tarnishing of silver and silver alloys used for LED packages due to hydrogen sulphide. Particularly, this test method is intended to give information on silver and silver alloy tarnishing effects to the luminous/radiant flux maintenance of LED packages. Additionally, this test method can give information on electric performances of LED packages due to corrosion of silver and silver alloys. The object of this test is to determine the influence of atmospheres containing hydrogen sulphide on parts of LED packages made of: silver or silver alloy; silver or silver alloy protected with another layer; other metals covered with silver or silver alloy. Testing other degradations that are susceptible to affect luminous/radiant flux maintenance and/or electric performance (e.g. degradation of copper or silicone parts) is not the object of this test. This test might not be suitable as a general corrosion test, i.e. it might not predict the behaviour of flux and/or electric characteristics and connections in industrial atmospheres. This document is applicable to LED packages for lighting applications only if referenced by an IEC SC 34A document.
