This part of IEC 61557 specifies the requirements for insulation fault location systems which localize insulation faults in any part of the system in unearthed IT a.c. systems and unearthed IT a.c. systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c.@ as well as in unearthed IT d.c. systems with voltages up to 1 500 V d.c.@ independent of the measuring principle. NOTE 1 IT systems are described in IEC 60364-4-41 amongst other literature. Additional data for a selection of devices in other standards should be noted. NOTE 2 Further information on insulation fault location can be found in the following standards: IEC 60364-4-41:2005@ 411.6@ and IEC 60364-5-53:2001@ 531.3

This International Standard provides elements for product conformity assessment. Critical defects on tools, devices and equipment for live working are not acceptable. Major defects on tools, devices and equipment for live working are likely to result in failure or in a significant reduction of functionality, while minor defects do not reduce significantly the functionality. This standard defines assessment methods for products having completed production phase to assure that they conform to the requirements of the corresponding product standard. It is to be used in conjunction with live working corresponding product standards. The following elements are not covered by the present document, but are included in each product standard: – type tests; – provisions and description for sampling and routine tests; – the identification and classification of the corresponding defects resulting from a risk analysis.
Live working - Conformity assessment applicable to tools, devices and equipment
This part of IEC 60695 provides guidance on the measurement and interpretation of heat release from electrotechnical products and materials from which they are constructed. Heat release data can be used as part of fire hazard assessment and in fire safety engineering, as described in the future IEC 60695-1-10 [1] and the future IEC 60695-1-1112]. 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. 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 basic safety publication will not apply unless specifically referred to or included in the relevant publications.
