Proper packaging is required because defective packaging and over-packaging create economic andenvironmental problems. For proper packaging, cushioning packaging design in which the drop height duringtransportation and mechanical shock fragility of the product are considered is an effective method. Although
the test method for determining mechanical shock fragility of a product is standardized, it is generally not
performed. Therefore, we developed a mechanical shock fragility test method for a product that could obtain theinformation necessary for cushioning design using only one sample. However, there were three issues: (1) two
types of shock waveforms, i.e., trapezoidal and half-sine waves were used for the test; (2) the critical accelerationthat was higher than the maximum acceleration of the trapezoidal wave could not be obtained; (3) the cargo
would be over-packaged if it generated a half-sine shock waveform. Therefore, we proposed a test method using
only half-sine waves to solve these issues. We demonstrated the reliability of the proposed test method using
actual products and succeeded in obtaining the critical acceleration of the product using the half-sine wave
when the acceleration band was broader than the maximum acceleration of the trapezoidal wave.
