IEC 60127-3:20 15+A1:2020适用于适用于印刷电路的超小型保险丝，用于保护通常在室内使用的电器、电子设备及其部件。它不适用于打算在特殊条件下使用的电器的超小型保险丝，例如在腐蚀性或爆炸性环境中。除IEC 60127-1的要求外，本标准也适用。本标准的目的是定义除IEC 60127-1要求之外适用的超小型熔断器的特殊和附加测试方法。IEC 60127-3的第三版取消并取代了1988年发布的第一版及其修正案1(1991)和修正案2(2002)。与上一版相比，此版本包括以下重大技术变更:-在标准表3和4中添加矩形熔丝作为替代； -在标准表2、3和4中添加一个小盒保险丝链作为替代； -在标准表2、3和4中添加高达10A的额定电流； -增加第6.5款； -增加第9.7款； -用于终端测试的额外样品（E1至E6）将随机选择，而不是按表1、2、3和4中的电压降分类。 该合并版本由第三版（2015年）及其修正案1（2020年）组成。因此，除本出版物外，无需下令修订。 关键词:适用于印刷电路、电器、电子设备及零部件保护的超小型熔断器 本出版物应与IEC 60127-1:20 06一起阅读。

IEC 60127-3:2015+A1:2020 is applicable to sub-miniature fuse-links adapted to printed circuits and used for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to be used indoors. It does not apply to sub-miniature fuse-links for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere. This standard applies in addition to the requirements of IEC 60127-1. The object of this standard is to define special and additional test methods for sub-miniature fuse-links applying in addition to the requirements of IEC 60127-1. This third edition of IEC 60127-3 cancels and replaces the first edition published in 1988, its Amendment 1 (1991) and Amendment 2 (2002). This edition includes the following significant technical changes with respect to the previous edition:
- add a rectangular shape fuse-link as alternative in standard sheets 3 and 4;
- add a small cartridge fuse-link as alternative in standard sheets 2, 3 and 4;
- add the rated currents up to 10A in standard sheets 2, 3 and 4;
- add Subclause 6.5;
- add Subclause 9.7;
- the extra samples for termination test (E1 to E6) will be chosen by random and not sorted by voltage drop in Table 1, 2, 3, and 4.
This consolidated version consists of the third edition (2015) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
Keywords: sub-miniature fuse-links adapted to printed circuits, protection of electric appliances, electronic equipment and component parts
This publication is to be read in conjunction with IEC 60127-1:2006.
