This standard was first published as IS 9224 (Part 4) : 1980 Low voltage fuses: Part 4 Supplementary requirements for fuse-links for the protection of semiconductor devices which covered requirements of LV fuses suitable for the protection of semiconductor devices. IS 9224 (Part 4) was then superseded by IS 13703 (Part 4) : 1993 in order to align the requirements of LV fuses with corresponding requirements at the IEC level. IS 13703 (Part 4) : 1993 was identical to IEC 60629-4 : 1980+ Amend 1:2012. The present revision is being undertaken in order to align with the latest IEC. The revised standard would supersede IS 13703 (Part 4) : 1993. The major differences between IS 13703 (Part 4) : 1993 and this standard are as follows: the introduction of voltage source inverter fuse-links, including test requirements; coverage of the tests on operating characteristics for a.c. by the breaking capacity tests; the updating of examples of standardised fuse-links for the protection of semiconductor devices. The text of IEC Standard would be considered for approval as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words International Standard appear referring to this standard, they should be read as `Indian Standard. b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
