35、CE1 .76-2: 1976, Transformateurs de puissance - Deuxime partie: Echauffement, comporte un systme de classification didentification des transformateurs, qui repose sur la nature de lagent de refroidissement et son mode de circulation. Les isolants liquides furent classs pour cela, selon leur comporte
36、ment au feu, en classe O (huile minrale ou liquide de synthse inflammable quivalent) et classe L (isolant liquide de synthse ininflammable). En 1984, le CE 10 de la CE1 se chargea ddifier une classification des isolants liquides suivant leur comportement au feu. En attendant les propositions du CE 1
37、0 de la CEI, le TC 14 du CENELEC fit un projet analogue de classification reposant sur le point de feu en ajoutant aux anciennes classes O et L une nouvelle classe K pour les liquides de point de feu suprieur a 300 OC. Bien que le point de feu soit largement reconnu comme tant significatif de la fac
38、ilit dinflammation dun liquide, le degr de risque dincendie dpend de la vitesse de dgagement de chaleur au cours de lincendie. II semble donc souhaitable dintroduire une proprit de classification additionnelle relie la quantit de chaleur dgage par le liquide au cours de sa combustion. Le systme de c
39、lassification des isolants liquides dcrit dans la presente Norme utilise deux caractristiques relies au feu: le point de feu et le pouvoir calorifique infrieur. Lorsque des mthodes normalises internationales appropries pour la dtermination de la vitesse de dgagement de chaleur ou dautres caractristi
40、ques de comportement au feu seront disporiibles, elles pourront tre incorpores dans cette classification. Le dessein nest pas de fournir une valuation compltede tous les aspects du risque dincendie, ni dtablir un ordre de mrite des isolants liquides, mais seulement de mettre dans la mme classe les l

43、e method of coolant circulation. Insulating liquids were classified therein according to their fire behaviour into classes O (mineral oil or equivalent combustible synthetic insulating liquids), and L (non-flammable synthetic insulating liquids). In 1984, IEC/TC 1 O undertook a classification of ins
44、ulating liquids according to fire behaviour. Pending IEC/TC 10 proposals, CENELEC/TC 14 drafted such a classification based on fire-point adding to. the former classes O and L a new class K for liquids with fire-point above 300 C. 4 ? While the value of fire-point to indicate the relative ease of ig
45、nition of a liquid is widely recognized, the degree of fire hazard depends on the rate of heat release during a fire. Therefore, it seemed desirable to include an additional classification property related to the heat energy generated by the liquid during its combustion. The classification system of
46、 insulating liquids described in this standard uses two fire- related characteristics: fire-point and net calorific value. When suitable, internationally standardized methods for the determination of heat release or other characteristics of fire behaviour become available, they may be incorporated i
47、n this classification. The intention is not to provide a complete evaluation of all aspects of fire hazard, neither to establish an order of merit of insulating liquid, but only to set in the same class those liquids that may require similar type and amount of safeguards for fire protection.
