[0002] According to the national standard GB / T20284-2008, "Single-piece Combustion Test for Building Materials or Products," test specimens must be manufactured with a short wing size of (495±5) mm x (1500±5) mm x original thickness, and a long wing size of (1000±5) mm x (1500±5) mm x original thickness. Currently, the standard format for flat-sheet insulation materials for building products is 1200 mm x 600 mm x (50-120) mm x original thickness. Multiple panels are spliced together to create the long and short wings.
