Annex A (informative) Classification system for determining
                      the combustibility of vertical
                      flexible specimens using a 20 mm
                      flame source

Defines a small-scale laboratory screening procedure for comparing the relative burning behaviour of vertically oriented thin and relatively flexible plastics specimens that are exposed to a low-energy flame ignition source. These cannot be tested using method B of ISO 1210 as they distort or shrink away from the flame source without igniting.
