Specifies a needle-flame test to simulate the effect of a small flame which may result from fault conditions, in order to assess by a simulation technique the fire hazard. It is applicable to electrotechnical equipment, its sub-assemblies and components and to solid electrical insulating materials or other combustible materials. This first edition of EN 60695-11-5 cancels and replaces the second edition of EN 60695-2-2, issued in 1991 and its amendment 1 (1994). It also constitutes a technical revision. The structure of this standard remains essentially the same with some major new changes and concepts added: - The scope has been broadened to allow this test method to also simulate the effects of small flames from outside the equipment. - A new concept has been added which allows the burner to be moved during the test to avoid dripping material from falling onto the tip of the burner tube. - The burner tube material is now a referenced source. - The reference for the copper block material has changed - the ISO publication (ISO 1337) has been withdrawn with no replacement. A new callout is now used. - Informative Annex B and a bibliography have been added. It has the status of a basic safety publication in accordance with IEC Guide 104.
