For class m, the deviation is ±0.5° or ±30 minutes for nominal lengths ≤120 mm, and ±0°20' per 100 mm length for larger features.
Avoid ambiguous phrasing like “DIN 7168 mH” – always reference the current ISO standard. iso 2768 m h

The "H" tolerance class in ISO 2768 provides a high level of tolerance for linear dimensions. The tolerances for this class are as follows: For class m, the deviation is ±0
