This part of this standard shows numerical values of dimensional tolerances in tolerance zone classes (tolerance zones) that are often used for holes and shafts, calculated based on the provisions shown in JIS B 0401-1. This part of this standard specifies the values for the upper dimensional tolerances ES (for holes) and es (for shafts) and the lower dimensional tolerances EI (for holes) and ei (for shafts) ( (see Figure 1). Note: In the dimensional tolerance table, except for tolerance classes JS and js, which are symmetrical around the reference line, the value for the upper dimensional tolerance ES or es is displayed above the value for the lower dimensional tolerance EI or ei. .
