Self-extinguishing materials for electric sector
The principal normative use, and applications in world are: UL 94.
In the electric sector, the risk of fire is normally tied up to electric breakdowns (overloads, short-circuits, etc.) more that to the free flames.
The self extinguishing is an ownership that is gotten through particular made formulations with additives retarding of flame that they prevent or they reduce the propagation of the flame in case of fire.
The classification of the tecnopolimers self extinguishing is:
HB CLASSIFICATION (happy burning) The test-tube burns normally without however free toxic gas.
CLASSIFICATION V2
The time of turning off of the test-tube from the removal of the flame is< 30 seconds.
The adds of 10 applications doesn't exceed the 250 seconds.
There be not phenomenons of alight fires after 60 sec. from the removal of the flame.
The drops that free themselves could set fire the material surrounding.
CLASSIFICATION V1
The time of turning off of the test-tube from the removal of the flame is< 30 seconds.
The adds of 10 applications doesn't exceed the 250 seconds.
There be not phenomenons of alight fires after 60 sec. from the removal of the flame.
The drops that free themselves don't set fire the material surrounding.
CLASSIFICATION V0
The time of turning off of the test-tube from the removal of the flame is< 5 seconds.
The adds of 10 applications doesn't exceed the 50 seconds.
There be not phenomenons of alight fires after 30 sec. from the removal of the flame.
The drops that free themselves don't set fire the material surrounding.
