What do you mean by the edge strength and the bursting strength of the board?
It seems to be a printed term, and I don't remember it. Bursting strength should be the ability of the paper to resist foreign forces until it breaks.Edge pressure: the maximum pressure at which the edge of a paper can withstand
Breaking strength (national standard GB/T 6545) under test conditions, the maximum pressure on the unit area of the corrugated cardboard is uniformly increased on the surface of the sample
Side pressure strength (GB/T 6546) samples of certain width, the unit length can withstand the pressure of called side pressure strength, unit refers to the national standard N/m. side strength refers to the vertical compressive strength, namely the corrugated cardboard corrugated direction parallel to the pressure bearing capacity.
