    In general B-quality boards have a good appearance. However, individual pieces do not fulfil A-quality requirements because the boards include one or more larger defects. Fully broken pieces are not accepted in B-quality. B-quality can easily be upgraded into A-quality grade by cutting off the defects.

    SEVERE SHAKES AND CRACKS
    SEVERELY DEFECTED EDGES
