CREATION OF A STAND FOR TESTING OF ROOFS ON RESISTANCE ТО EXTERNAL FIRE INFLUENCE

Abstract

Abstract. The topicality of works for testing roofs on resistance to external fire influence for creation the conditions of improving the level of fire safety for construction in Ukraine is shown. The expediency of introducing in Ukraine а separate method for the extended application of test results  of roofing materials , namely the test method № 2 in accordance with DSTU CEN/ТS 1187: 2016 "Methods of testing roofs by external fire (CEN/TS 1187: 2012, IDT)" was confirmed. For the first time in Ukraine, at the level of European approaches, the design and working design documentation of а test stand for testing of roofs on resistance to external fire influence has been developed. The general appearance and composition of the stand, including the ignition source, are given. Technical characteristics of the stand have been determined. The parameters of gas supply to the ignition source are substantiated and experimentally confirmed. Technical characteristics of the created stand allow to саrrу out tests of roofs test specimens with standardized size of basis, thickness of the test specimen to 200 mm and weight to 30 kg. The means of measuring equipment necessary for carrying out tests are given. The procedure of calibration of the stand, the procedure of carrying out tests and requirements for evaluation of test results are given. Materials for verification of the stand have been prepared, the results of which will certify the basic parameters, technical characteristics and actual values of standardized metrological indicators guaranteed bу the developer and manufacturer of the stand for testing of roofs on resistance to external fire influence in accordance with the requirements and methods given in DSTU CEN/TS 1187: 2016. Suggestions for further use of test results on the created stand are given.
