摘要
Provided is a method for predicting the remaining life of a hose and a method for diagnosing the deterioration level of a hose that can be easily performed without breaking the hose. The disclosure includes: a testing step of performing a hose bending test; and a predicting step of predicting the remaining life of a hose subject to prediction, wherein during the hose bending test, either a value of an external force required to displace a hose portion in a direction of the external force by a predetermined displacement amount, or a value of a displacement amount in a direction of the external force of the hose portion when the external force of a predetermined magnitude is exerted on the hose portion is measured, and the measured value is obtained as the test result.
