No metal impurity is permitted. The impurities should be no more than 2 and their size should be no more than 1mm. Its plate is with clean surface and even texture and impurities and flecks are no more than 6, among which, impurities of 0.5mm-2mm are no more than 2 and flecks sized 2mm-3mm are no more than 1. Experimental Results There should be no more than 2 flecks sized no bigger than 1mm on every 100×100mm2 of circular plate sized Φ250×2mm.
