ASTM C42 correction factors (multiplied): k_LD: 2.0→1.00, 1.75→0.98, 1.50→0.96, 1.25→0.93, 1.00→0.87 (interpolate). k_d: ≥ 100 mm→1.00, 75 mm→0.98, 50 mm→0.94. k_m: soaked→1.09, air-dried→0.96, as-received→1.00. k_a: perp→1.00, parallel→0.92 (horizontal core in wall, with casting axis lying in the cylinder axis direction).
