Dimension tolerances of thickness

The allowable deviation of the thickness of the sheet and steel strip shall comply with the requirements of the ordinary precision in the table. If the buyer requires it and indicates it in the contract, the higher precision (ET) and (ST) in Table 1 can be implemented.
