IEC 60127-8:20 18+AMD1:2024 CSV涉及具有额定高达AC 500 V和/或DC 500 V的特定过电流保护的保险丝电阻器，用于保护通常打算在室内使用的电器、电子设备及其部件。它不适用于在特殊条件下使用的具有特殊过电流保护的熔断电阻器，例如在腐蚀性或爆炸性环境中。 IEC 60127这一部分的目的是 a)对具有特殊过电流保护的熔断电阻器建立统一要求，以便以最合适的方式保护电器或电器的部件； b)定义具有特殊过电流保护的熔断电阻器的性能，以便为电器和电子设备的制造商提供指导，并确保以类似的熔断电阻器取代具有特殊过电流保护的熔断电阻器尺寸和特性； c)为具有特定过电流保护的熔断器电阻器建立统一的测试方法，以便允许验证制造商规定的值（例如额定耗散、工作特性和额定分断能力值）。 除了IEC 60127-1的要求之外，IEC 60127的这一部分也适用。IEC 60127-8的第一版取消并取代了IEC PAS 60127-8:20 14。本国际标准将与IEC 60127-1一起使用。 关键词:微型熔断器熔断器电阻过流保护

IEC 60127-8:2018+AMD1:2024 CSV relates to fuse resistors with particular overcurrent protection rated up to AC 500 V and/or DC 500 V for printed circuits and other substrate systems, used for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to be used indoors. It does not apply to fuse resistors with particular overcurrent protection for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere.
The object of this part of IEC 60127 is
a) to establish uniform requirements for fuse resistors with particular overcurrent protection so as to protect appliances or parts of appliances in the most suitable way;
b) to define the performance of the fuse resistors with particular overcurrent protection, so as to give guidance to manufacturers of electrical appliances and electronic equipment and to ensure replacement of fuse resistors with particular overcurrent protection by those of similar dimensions and characteristics;
c) to establish uniform test methods for fuse resistors with particular overcurrent protection, so as to allow verification of the values (for example rated dissipation, functioning characteristic and rated breaking capacity values) specified by the manufacturer.
This part of IEC 60127 applies in addition to the requirements of IEC 60127-1. This first edition of IEC 60127-8 cancels and replaces IEC PAS 60127-8:2014. This international standard is to be used in conjunction with IEC 60127-1.
