Не д а в ние и с с л е дов а ни я продемонстрировали, что определение выделяющихся веществ в ходе полномасштабных испытаний (таких, как prEN50399)вреальноммасштабевремени является возможным и что подобные результаты могут использоваться в качестве исходных данных при имитационном моделировании. Однако представляется очевидным, что прежде, чем можно было бы обеспечить какую- либо стандартизацию, потребуется проведение дополнительных исследований. Используя имеющиеся у нее и уже наглядно продемонстрированные возможности для инвестирования в научные исследования, кабельная промышленность сможет успешно решать задачи, обусловленные появлением любых новых нормативно- правовых требований или потребностей конечных пользователей в отношении характеристик огнестойкости продукции, которую она выпускает. n 1 Zanelli, C, Philbrick, S, Beretta, G, “Cavi e pericolo di incendio”Cired, London 1973 2 Philbrick, S, McConnell, J,“Cables having improved fire performance”Jicable 84, Versailles 1984 3 Journeaux, T, Beratta, G, Gautier, P, “Development of cables with improved fire performance characteristics”Jicable 87, Versailles 1987 4 Journeaux, T, “The development of new standards for offshore cabling” PRI Conference Polymers for Offshore Cabling Proceedings, London 1987 5 IEC Standard IEC 60332-3-10:2000 + A1:2008 Tests on electric cables under fire conditions – Part 3-10: Test for vertical flame spread of vertically mounted bunched wires or cables – Apparatus 6 IEC Standard IEC 60754-1:1994 Test on gases evolved during combustion of materials from cables – Part 1: Determination of the amount of halogen acid gas 7 IEC Standard IEC 60754-2:1997 Test on gases evolved during combustion of electric cables – Part 2: Determination of degree of acidity of gases evolved during the combustion of materials taken from electric cables by measuring pH and conductivity 8 IEC Standard IEC 61034-2:2005 Measurement of smoke density of cables burning under defined conditions – Part 2: Test procedure and requirements 9 Gibbons, J, Stevens, G, “Limiting the corrosion hazard from electrical cables involved in fires” Fire Safety Journal 15 p183-190, 1989 10 Telecom Australia, Design standards Branch, HQ Fire loss report, 1987 11 Stevens, G, “The appraisal and significance of acidic gas emissions from burning electric cable materials,” 5 th BEAMA International Electrical Insulation Conference, Brighton 1986 12 Journeaux, T, “The development and manufacture of Sizewell B cables,” Proceedings IEE International Conference on control aspects of the Sizewell B PWR, p74-79 London 1992 13 Hull, T, Stec, A, Paul, K, “Hydrogen Chloride in Fires,” IAFSS 9 th International symposium, Karlsruhe 2008 14 Hertzberg, T, Blomqvist, P, Lastbom, L, “Influence of HCl and PVC-smoke on isolated and perfused guinea pig lungs,” SP Fire Technology Report 57, 2006 Справочная литература
