低压开关设备和控制设备 第5部分：控制电路设备和开关元件 第4部分：评估低能量触点性能的方法 特殊测试

[中文适用范围]： 适用于所考虑的使用领域中使用的可分离触点，例如控制电路的开关元件。考虑两个额定电压：高于（含）10 V（通常为 24 V），其中触点用于开关可能存在电蚀的负载，例如可编程控制器输入；低于 10 V（通常为 5 V），电蚀可忽略不计，例如电子电路。这是一种评估低能量接触性能的提议方法，给出了： 有用的定义；测试方法的一般原则是监测和记录每次操作时触点的行为；定义通用测试设备的功能基础；优选的测试值；测试用于特定应用的触点的特定条件（例如 PC 输入的切换）；测试报告中应提供的信息；测试结果的解释和呈现。 [外文原描述]： Applies to separable contacts used in the utilisation area considered such as switching element for control circuits. Two rated voltages are taken into consideration: above (and including) 10 V (typically 24 V) where contacts are used for switching loads with possible electrical erosion, such as programmable controller inputs, and below 10 V (typically 5 V) with neglible erosion, such as electronic circuits. It is a proposed method of assessing the performances of low energy contacts giving: useful definitions; general principles of test methods which are to monitor and record the behaviour of contacts at each operation; functional bases for the definition of a general testing equipment; preferred test values; particular conditions for testing contacts intended for specific applications (such as switching of PC inputs); information to be given in the test reports; interpretation and presentation of the test results.
