The purpose of this study is to compare the wire to be used for hydrogen charging hose though a tensile test. For the sample, 3 types of high pressure hose wires were prepared with a diameter of 0.38, 0.36(the reference sample) and 0.30. Each of 6 samples was tensile tested for 3 wires. The average break force of the reference sample was 29.87 kgf, and the average break force of the other samples were 35.30 kgf and 19.62 kgf. The results show that it is appropriate to apply a product with a diameter of about 0.35 mm compared to the reference sample. In the tensile strain ratio, compared to the reference sample, the stretch is somewhat lower than that of the reference sample, so it is necessary to apply a wire that stretches better.
