| description | Provided is a pressure testing method for a high-pressure tank capable of avoiding a destruction of the high-pressure tank during a pressure test. A pressure testing method includes: extracting a plurality of AE waveforms from output waveforms of an AE sensor while increasing a pressure inside the high-pressure tank; and testing the high-pressure tank based on the extracted plurality of AE waveforms. The method includes: while increasing the pressure inside the high-pressure tank, classifying the extracted AE waveforms into first waveforms and second waveforms with a classifier that is machine-learned so as to classify the plurality of AE waveforms into the first waveforms derived from a macrocrack that increases immediately before destruction of the high-pressure tank, and the second waveforms derived from a microcrack smaller than the macrocrack; and stopping pressurization of the high-pressure tank based on the number of the first waveforms. |
