The thickness of the washer should not vary away from the thickness stated in the table because all washers are made from standard sheets of metal that are 

0.6/-0mm Thickness (T) Tolerance; M20 (20mm) For Use With Thread Size; +0.62/-0mm External Diameter (OD) Tolerance; +0.33/-0mm Internal Diameter (ID) 

21.1. Under ASME B18.21.1, dimensional tolerances for plain washers, there are two types specified, type A and type B. Type A has two series 

Therefore engineers define general tolerances in engineering drawings to define the variation. ISO 2768 standard defines general tolerance for: Linear Dimensions. Angular Dimension. External Radius and Chamfer height. Geometric tolerance such as straightness, flatness, perpendicularity, symmetry, and runout. We suggest you read this article on
