After the test, the fire sources should be examined visually
to determine compliance with the required maximum damage. The damages
should be estimated using the following formula:
-
.1 damage to lower bunk bed = (damage to horizontal
mattress (%) + 0.25 x damage to pillow (%) + damage to backrest (%))/2.25;
-
.2 damage to upper bunk bed = (damage to horizontal
mattress (%) + 0.25 x damage to pillow (%))/1.25; and
-
.3 if it is not clearly obvious by visual examination
whether the criteria are fulfilled or not, the test should be repeated.
