A The thickness was measured not less than 3 / 8in. [9.52mm] along the longitudinal edge, but not more than 3in.[76.20mm] away from the edge. B Plate with a thickness less than or equal to 10in.[254.0mm], with a negative deviation of 0.010in. [0.25mm]. C For circles, the thickness tolerance performs those whose diameter is within the table width; for irregular plates, the positive tolerance performs within the table width where its maximum width is located. |
