IEC 60695-1-10:2016 provides general guidance with respect to fire hazard testing on how to reduce to a tolerable level the risk of fire and the potential effects of fires involving electrotechnical products. It also serves as a signpost standard to the other guidance publications in the IEC 60695 series. It does not give guidance on the use of fire-resistant compartment boundaries or on the use of detection and suppression systems for the mitigation of fire risk. It describes the relationship between fire risk and the potential effects of fire, and provides guidance to IEC product committees on the applicability of qualitative and quantitative fire tests to the fire hazard assessment of electrotechnical products. Details of the calculation of fire risk are not included in the scope of this document. It emphasises the importance of the scenario approach to fire hazard and risk assessment and discusses criteria intended to ensure the development of technically sound hazard-based fire test methods. It discusses the different types of fire tests, in particular the nature of qualitative and quantitative fire tests. It also describes the circumstances under which it is appropriate for IEC product committees to maintain or develop qualitative fire tests. This standard is intended as guidance to IEC committees, and is to be used with respect to their individual applications. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – reference to IEC 60695-1-12; – modified Introduction and Scope; – updated normative references; – updated terms and definitions; – modified Table 1; – addition of Table 2; – new text in Subclauses 5.2, 5.3 and 5.4; – mandatory text in Clause 8; – Annex B changed to Annex A, and modified; – new Annex B concerning common ignition sources. This publication is to be read in conjunction with /2 and /2. It has the status of a horizontal standard in accordance with /2 and ISO/IEC Guide 51. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. Key words: Fire Hazard, Fire Risk, Fire Safety Engineering
