Flame Spread. 		Apply the test flame from a propane gas torch for 10 sec. in the vertical position and observe:

a) whether any flaming reaches the upper edge or either vertical edge of the test specimen;

b) afterflame time;

c) whether afterglow spreads beyond the flame spread area into the undamaged area;

d) afterglow time;

e) the occurrence of debris;

f) whether debris ignites the filter paper (flaming debris), if applicable;

g) whether a hole develops, and in which layer(s) for a multiplayer specimen.

Protective clothing to protect against heat and flame 		EN ISO 6942:2002
(Replaces EN 366)

Radiation Heat.
(Test method B)		 In a vertical position the material is exposed to a radiant heat equivalent to 20KW/m².
(C1-C4) indicate the timescale for temperature increases on the opposite side.
EN367 + AC: 1994

Heat transmission		 In a horizontal position the material is exposed to a flame from a propane gas burner, equivalent to 80KW/m².
The level (B1-B5) indicates the time interval before a temperature increase of 24° C (pain threshold) on the upper side.
EN ISO 9185:2007
(Replaces EN 373)

Resistance to splash of molten metal		 The material is exposed - at an angle of respectively 60° and 75° - to splash of molten aluminium (about 780° C) and molten iron (about 1400° C). The level (D1-D3/E1-E3) indicates how many grams can be poured without damaging a PVC film (skin simulator) on the back of the test material.

Limited flame spread materials.		 EN ISO 15025:2002

Flame Spread. 		After 10 sec. influence of the flame from propane gas torch in vertical position classified material under index 1, 2, and 3
Cleaning in line with the manufacturer’s instruction, if not specified, 5 cycles shall be performed.

Hazards of an electric arc.		 The protective clothing shall have no negative influence on the effect of the electric arc.

Acceptance criteria for tests on materials with a burning time ≤5 sec

A.  No melting through to the inner side
B. No hole bigger than max 5 mm in every direction (in the innermost layer)

All value pairs are below the corresponding value Stroll on the test curve.

The test parameters are fixed into two test classes: Class 1 and Class 2
