This section is equivalent to using IEC 60598-2-6:1994 "lamps - Part 2. Particular requirements Chapter 6. tungsten with built-in transformer Lamps "and 1996 Revision 1 piece or converter. This made the following section editorial changes to the text.

--- Since the 2003 publication 2.2 6th edition of IEC 60598-1 has been deleted Category 0 type lamps, so in this part of the revision When deleting the original in the range of "0 to not more than 250V type lamps" text of article classification description 4 in the lamp "Class 0", on the last paragraph of Article 6.1 of the relevant provisions 0 class structure also deleted.

1.1 --- original reference documents because the IEC 60742 GB identical with the first one has been equivalent to 13028 IEC GB 19212.1 61558-1 alternatives, so increasing the reference standard GB 19212.1 time of writing.

--- original 1.1 reference documents IEC 1046:1993 IEC 61347-2-2 has been replaced so when the original written

IEC 1046 instead equivalent to the national standard of GB 19510.3 IEC 61347-2-2.

This partial replacement GB 7000.6-1996 "filaments lamps built-in transformers safety requirements", and the standard edition GB 7000.6- The main technical difference between the 1996 version of the standard include.

--- standard name to "lamps - Part 2-6. Particular requirements with built-in transformers or converters tungsten lamp." --- insert "or switch" or "or (SELV) converter" After a plurality of articles "transformer", as the terms of paragraph 1 and 1 3 segments; Terms of from 3.2 to 3.7; the end of the injection at the end of clause 5 and 8.1 the second line and the like.

5.5 --- modification, when the invisible with normal operation of the converter transformer or fuse alternatively, should the transformer or converter Mark symbol on the fuse unit. Appendix A of this section is normative.
