标准范围

IEC 60127-7:20 15涵盖了特殊应用的微型保险丝的要求。IEC 60127的这一部分适用于额定电压不超过1 000 V、额定电流不超过20 A、额定分断能力不超过50 kA的熔丝。它不适用于IEC 60269-1后续部分完全涵盖的熔断器。它不适用于打算在特殊条件下使用的电器的微型保险丝，例如在腐蚀性或爆炸性环境中。除了IEC 60127-1的要求之外，IEC 60127的这一部分也适用。特殊应用的微型保险丝不打算由电气/电子设备的最终用户更换。IEC 60127这一部分的目的是为微型保险丝建立统一的测试方法-特殊应用的链接，以便允许验证制造商指定的值（例如熔化时间和断裂能力值）。这第二版取消并取代了2013年出版的第一版。与上一版相比，此版本包括以下重大技术变更:-定义用于表面安装熔丝链路的测试板，图2；-定义同质系列的测试时间表。本出版物应与IEC 60127-1:20 06一起阅读。关键词:额定电压不超过1 000 V、额定电流不超过20 A、额定分断能力不超过50 kA的熔断器。

IEC 60127-7:2015 covers requirements for miniature fuse-links for special applications. This part of IEC 60127 is applicable to fuse-links with a rated voltage not exceeding 1 000 V, a rated current not exceeding 20 A and a rated breaking capacity not exceeding 50 kA. It does not apply to fuses completely covered by the subsequent parts of IEC 60269-1. It does not apply to miniature fuse-links for appliances intended to be used under special conditions, such as in corrosive or explosive atmospheres. This part of IEC 60127 applies in addition to the requirements of IEC 60127-1. Miniature fuse-links for special applications are not intended to be replaced by the end-user of an electrical/electronic appliance. The object of this part of IEC 60127 is to establish uniform test methods for miniature fuse-links for special applications, so as to allow verification of the values (for example melting time and breaking capacity values) specified by the manufacturer. This second edition cancels and replaces the first edition published in 2013. This edition includes the following significant technical changes with respect to the previous edition:
- defining a test board for surface mount fuse-links, Figure 2;
- defining test schedules for homogenous series.

This publication is to be read in conjunction with IEC 60127-1:2006. Keywords: fuse-links with a rated voltage not exceeding 1 000 V, a rated current not exceeding 20 A and a rated breaking capacity not exceeding 50 kA.
