EN 60695-11-10：Fire hazard testing-Part 11-10: Test flames 50 W horizontal and vertical flame test methods
Abstract摘要
Horizontal Testing (HB) - Method A
Procedure: A specimen is supported in a horizontal position and is tilted at 45°. A flame is applied to the end of the specimen for 30 seconds or until the flame reaches the 1 inch mark. If the specimen continues to burn after the removal of the flame, the time for the specimen to burn between the 1 and 4 inch marks are recorded. If the specimen stops burning before the flame spreads to the 4 inch mark, the time of combustion and damaged length between the two marks is recorded. Three specimens are tested for each thickness.

HB

Specimens must not have a burning rate greater than 1.5 inches/minute for thicknesses between 0.120 and 0.500
inches and 3 inches/minute for thicknesses less than 0.120 inches. Specimens must stop burning before the flame reaches the 4 inch mark.

Vertical Testing (V-0, V-1, V-2) - Method B
Procedure: A specimen is supported in a vertical position and a flame is applied to the bottom of the specimen. The flame is applied for ten seconds and then removed until flaming stops at which time the flame is reapplied for another ten seconds and then removed. Two sets of five specimens are tested. The two sets are conditioned under different conditions.
