标准范围

IEC 60747-5-13:20 21提供了加速测试方法，用于评估硫化氢对LED封装所用银和银合金失去光泽的影响。特别地，该测试方法旨在给出关于银和银合金变色效应对LED封装的光通量/辐射通量维持的信息。此外，该测试方法可以提供由于银和银合金腐蚀而导致的LED封装的电性能的信息。本测试的目的是确定含有硫化氢的气氛对由以下材料制成的LED封装部件的影响:银或银合金；用另一层保护的银或银合金；其他镀有银或银合金的金属。测试易影响光通量/辐射通量维持和/或电气性能的其他退化(例如。g.铜或有机硅部件的降解）不是本测试的对象。该测试可能不适合作为一般腐蚀测试，即它可能无法预测工业环境中的焊剂和/或电气特性和连接的行为。仅当IEC SC 34A文件引用时，本文件才适用于照明应用的LED封装。

IEC 60747-5-13:2021 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.
