Introduction:
The electrical burner test according to NF P *****3 is the reaction to fire main test for M classification of building and fitting materials. It is used for flexible materials with a thickness lower than or equal to 5 mm, for tight fitting flexible wall and ceiling coatings of any thickness and for flexible filtering media of any thickness.
In principle, if the duration of inflammation after withdrawing the pilot flame does not exceed 5 s, the material can be M1 classified. Beyond 5 s of inflammation, the M2 or M3 classification will be made according to the average distance of charring or destruction and possibly also the average width of charring or destruction of the test piece. In case of inflamed or not dripping, the dripping test (NF P *****5) is carried out. If there is some holing without inflammation or with short time inflammation, classification is obtained after performing the flame persistency test (NF P *****4).

Feature:

1. Quickly place the grill fitted with with the test piece on the test piece holder grill facing to the electrical burner.
2. Simultaneously start the stopwatch (zero-time of test).
3. Immediately lower the incombustible plate onto the grill pins.
4. *0 seconds after the the start of testing, rotate the inflammation system in such a way to bring the pilot flame into the contact position under the test piece and hold it in position for 5 s, then withdraw it.
5. Repeat this action *5 s after the start of testing, then every *0 s for at least 5 min, excepted if the material burns ; in this case, its necessary to wait until the material is extinguished in order to reapply the pilot flame at the next application time set out in the standard.
6. During the test, note the time of inflammation and its duration after withdrawing the pilot flame.
7. Electrical burner test apparatus allows to perform automatically all the operating sequence including recording of the flame duration determined by push- activation.
