SIST EN 61549:2004

SIST EN 61549:2004 is the Slovene adoption of EN 61549:2003, published by SIST. It covers miscellaneous lamps - lamps not covered elsewhere in the scope of existing IEC standards - and gives a common reference for manufacturers, specifiers, buyers, and test laboratories working with those lamp types.

What does SIST EN 61549:2004 specify?

SIST EN 61549:2004 specifies the reference standard for miscellaneous lamps, meaning lamp types that fall outside the scope of other IEC lamp standards. In practice, that tells a reader whether a lamp belongs under this document when selecting a standard for design, procurement, or conformity work.

SIST EN 61549:2004 is identified in the text as identical to EN 61549:2003 and linked to IEC 61549:2003. The front matter also places it in the lamp field covered by the ICS classes for incandescent lamps and fluorescent/discharge lamps, which helps users find it in the broader family of lamp standards.

The document is presented as a European Standard with multilingual title pages and approval information. Its foreword and endorsement notice show that the IEC text was accepted by CENELEC without modification.

What changed in SIST EN 61549:2004 from the previous edition?

SIST EN 61549:2004 replaces SIST EN 61549:1999, SIST EN 61549:1999/A1:1999 and SIST EN 61549:1999/A2:2002. At European level, EN 61549:2003 supersedes EN 61549:1996 + A1:1997 + A2:2001.

The foreword also states that the text of IEC 61549:2003 was approved by CENELEC as EN 61549 without any modification. For users, that means the European version follows the IEC wording directly.
