Patent ID: 7712377

Claim:
Test procedure for use in mass-producing a batch of hoses, one after another, where the hoses comprise respective lengths of elastomeric tubing and respective hollow metal ferrules; the test procedure is effective to determine, on a hose-by-hose basis, whether the tubing is properly present inside the ferrule, and includes: pressing a dimple inwards into the metal of the ferrule, in such manner as to make an indentation in the metal; providing a dimple-force measuring-device, and measuring the force needed to form the dimple, termed the dimple-force; determining a threshold value for the dimple-force; making an assessment, in respect of the individual hoses, whether the dimple-force is above or below the threshold; and accepting those hoses of the batch in respect of which the dimple-force is above the threshold, and rejecting those hoses of the batch in respect of which the dimple-force is below the threshold.
