IEC 60695-2-10 Ed. 2.0 b:2013

IEC 60695 2 10 2013 specifies the glow wire apparatus and common test procedure to simulate the effects of thermal stresses which may be produced by heat sources such as glowing elements or overloaded resistors for short periods in order to assess the fire hazard by a simulation technique The test procedure described in this standard is a common test procedure intended for the small scale tests in which a standardized electrically heated wire is used as a source of ignition It is a common part of the test procedures applied to end products and to solid electrical insulating materials or other solid combustible materials A detailed description of each particular test procedure is given in the respective standards IEC 60695 2 11 IEC 60695 2 12 and IEC 60695 2 13 This second edition of IEC 60695 2 10 cancels and replaces the first edition of IEC 60695 2 10 published in 2000 This edition constitutes a technical revision The main changes with respect to the previous edition are as follows br A table of contents has been added br The introduction has been updated to align with other TC89 documents br The scope has been clarified to align with other documents in the IEC 60695 2 Glow wire series br Terms and definitions relevant to this document have been added br Clause 4 has been deleted and the remaining clauses renumbered br The description of the power supply has been updated with additional details see 4 1 br The temperature measuring system see 4 3 and the description of the specified layer has been updated see 4 4 br New guidance has been introduced to assist in the verification of the temperature measuring system see 5 2 and Annex C br The common test produced has been clarified see Clause 7 br The tolerances have been changed for the dimensions of the glow wire see Figure 1 br New guidance on flaming observations has been added see Annex B It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO IEC Guide 51 This standard is to be used in conjunction with IEC 60695 2 11 IEC 60695 2 12 and IEC 60695 2 13 Keywords Glowing hot wire Glow wire.
