the volume enclosed between the first sides of the first and second wood element is calculated,
the volume of the adhesive filled is measured,
the calculated volume is compared with the measured volume, and
a statement is made about the quality of the connection on the basis of the comparison.

### Claim 5 (depends on 4)

Method according to claim 4, wherein
the volume enclosed between the first sides of the first and second wood element are subdivided in sub-volumes sealed vis-à-vis one another,
the volume of a first sub-volume enclosed between the first sides of the first and second wood element is calculated,
the volume of the adhesive filled into the first sub-volume is measured,
the calculated volume is compared with the measured volume, and
a statement is made about the quality of the connection on the basis of the comparison.

### Claim 6 (depends on 1)

Method according to claim 1, wherein the distance is greater than 0.3 mm.
