The standard ensures that parts are interchangeable and that pumps from different manufacturers (or replacement parts from third parties) will fit and function correctly within the specified limits. Detailed Overviews The standard ensures that parts are

This table provides permissible deviations in millimeters for external sizes (shafts), internal sizes (holes), and features like step heights or radii. For a nominal size range (e.g., 0.5 mm up to 3000 mm), the table lists the upper and lower deviation limits for each class. For example, a 100 mm linear dimension under the “medium” class might show a tolerance of ±0.3 mm, while the “fine” class would show a tighter ±0.1 mm.
