In this resp
29、ect the objective of component, circuit, and product design, as well as the choice of materials, is to reduce to acceptable levels the potential risks of fire during normal operating conditions, reasonable foreseeable abnormal use, malfunction, and/or failure. IEC Technical Committee 89 has develope
30、d IEC 60695-1-10, together with its companion, IEC 60695-1-11, to provide guidance on how this is to be accomplished. The primary aims of IEC 60695-1-10 and IEC 60695-1-11 are to provide guidance on how: a) to prevent ignition caused by an electrically energized component part, and b) to confine any
31、 resulting fire within the bounds of the enclosure of the electrotechnical product in the event of ignition. Secondary aims of these documents include the minimization of any flame spread beyond the products enclosure and the minimization of harmful effects of fire effluents such as heat, smoke, tox
32、icity and/or corrosivity. Fires involving electrotechnical products can also be initiated from external non-electrical sources. Considerations of this nature should be dealt with in the overall fire risk assessment. IEC 60695-11-2 provides a description of the apparatus required to produce a 1 kW te
33、st flame, and provides a description of the principle of a confirmation procedure to check that the effective power output of the flame is as intended. Guidance on confirmatory tests for test flames is given in IEC/TS 60695-11-40. This international standard may involve hazardous materials, operatio
34、ns, and equipment. It does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this international standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. BS EN

This basic safety publication is intended for use by technical committees in the preparation of standards in a
37、ccordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basi

The fl
46、ame shall be symmetrical, stable and give a result of 46 s 6 s in the confirmatory test described in Clause 6. The confirmatory test arrangement shown in Figure A.8 shall be used. 4.2 Apparatus and fuel 4.2.1 Burner The burner shall be in accordance with Figures A.1 to A.5 inclusive. NOTE The gas in
47、jector and flame stabilizer are removable for cleaning purposes. 4.2.2 Flow control Flow controllers shall be used and shall be capable of: the measurement and control of a propane gas flow rate of about 650 cm3/min at 23 C and 0,1 MPa, with an accuracy of 2 %, the measurement and control of an air
48、flow rate of about 10 dm3/min at 23 C and 0,1 MPa, with an accuracy of 2 %. NOTE Mass flow controllers will probably have to be used in order to meet the requirements of Clause 5.
