a. Fundamental deviations A and B shall not be used for nominal sizes u1 mm.
b. Special case: for tolerance class M6 in the range above 250 mm up to and including 315 mm, ES = −9 µm (instead of –11 µm according to the calculation). c. For determining the values K and M, click to see Establishment of limit deviations using ∆-values (EN ISO 286-1). d. For ∆ values, see Table 3. |
