(1) calculated on the base of nominal thickness values and to the specific value of 7.14 Kg/dm3 (1) calculated on the base of nominal thickness values and to the specific value of 7.14 Kg/dm3 (3) for all requests for a slightly higher or lower tolerance value in regards to thickness, the tolerance value will be doubled. For plates with a thickness superior to 2.68 mm, tolerances will be agreed upon beforehand. For coils with a thickness superior to 0.85 mm tolerances will be agreed upon beforehand.
