IEC 60695-11-5:2016 is also available as \/2 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60695-11-5:2016 specifies a needle-flame test to simulate the effect of a small flame which may result from fault conditions, in order to assess the fire hazard by a simulation technique. The results of this test may be used as elements of a fire hazard assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. It is applicable to electrotechnical equipment, its sub-assemblies and components and to solid electrical insulating materials or other combustible materials. This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – The scope has been broadened to allow this test method to also simulate the effects of small flames from outside the equipment; – Propane and butane gas are the specified fuel source with a minimum purity of 95 %; – 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referenced source; – The reference for the copper block material has changed – the ISO publication (ISO 1337) has been withdrawn with no replacement.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 and Informative Annex C and a bibliography have been added. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in \/2 and ISO\/IEC Guide 51.<\/p>\n
