According to DIN ISO 3547, part 2 (former DIN 1494), there are the following possibilities to gauge wrapped bushings:
- Method A (part 2 3.1) for large series
- Method C (part 2 3.3) for small and medium series. By method C, the bushing is pressed into a ring gauge with a diameter lying in the middle of the housing bore tolerance H7. The bushing ID is then checked by a go-no-go gauge.
IMPORTANT: Wrapped bushings cannot be measured in the unfitted condition.
