Harmonizing with the international standard ІЕС 60331 (parts 11, 12, 21, 23, 25, 31) popup.stage_title Head Kravchenko Rostislav Ivanovich, Registration Date 31-05-2007 Organization The Ukrainian Fire Safety Research Institute of the MOE of Ukrainee popup.description2 Object of research - fire danger of cables and methods of its{her} estimation. Object of research - ability cables to preservation of integrity of circuits in conditions of influence of fire. The purpose of work - development of projects of national standards of Ukraine (ДСТУ) on methods of тests cables on ability to preservation of integrity of the circuits harmonized with the international standard ІЕС 60331 (parts 11, 12, 21, 23, 25, 31). Methods of research - the analysis of normative documents on cables and methods of their tests for ability to preservation of integrity of circuits in conditions hot-fire influences. The analysis of normative base on cables is made. It is revealed, that in the international standards on these products their test methods on ability to preservation of integrity of circuits in conditions hot-fire influences are normalized. These test methods are established in a series of standards of the International electrotechnical commission ІЕС 60331-11, ІЕС 60331-12, ІЕС 60331-21, ІЕС 60331-23, ІЕС 60331-25 that ІЕС 60331-31. By results of the analysis of requirements of these international standards it is determined necessity of their introduction at national standards with a degree of conformity - identical. Results НИР are introduced into six projects of national standards with the general(common) name " Tests of electric cables by fire. Integrity of circuits.
