IEC 60695-1-21:2016 provides a summary of test methods that are used to determine the ignitability of electrotechnical products or materials from which they are formed. It also includes test methods in which, by design, ignitability is a significant quantifiable characteristic. It represents the current state of the art of the test methods and, where available, includes special observations on their relevance and use. The list of test methods is not to be considered exhaustive, and test methods which were not developed by the IEC are not to be considered as endorsed by the IEC unless this is specifically stated. This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with \/2 and ISO\/IEC Guide 51. It is not intended for use by manufacturers or certification bodies. This first edition of IEC 60695-1-21 cancels and replaces the first edition of IEC TR 60695-1-21 published in 2008. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – Change from a TR to an international standard; – Modified Introduction; – Modified Scope; – Updated normative references; – Updated terms and definitions; – Updates and new text in Clause 4; – Addition of text concerning ASTM D 3638; – Updates to Annex A and Updates to the bibliography. Key words: Fire Hazard, Fire Safety Engineering, Ignitability.<\/p>\n
