METHOD FOR PREDICTING REMAINING SERVICE LIFE OF HOSE AND METHOD FOR DIAGNOSING DETERIORATION OF HOSE

摘要

Provided are a method for predicting the remaining service life of a hose and a method for diagnosing the deterioration of a hose that are able to be easily executed without destroying the hose. The present invention includes: a test step that performs a hose bending test; and a prediction step that predicts the remaining service life of the hose that is the subject of prediction. In the hose bending test, the external force required to displace the hose section in question by a predetermined displacement amount in the direction of the external force, or the amount of displacement in the direction of the external force of the hose section in question when the external force of a predetermined magnitude is caused to act on the hose section in question is measured and obtained as test results.
