Parameters
| Technical Parameter | Description |
|---|---|
| Digital height gauge | Can display height in real - time, with a measuring range of 0 - 500mm |
| Positioning method | Adopts infrared positioning |
| Sample preparation for measurement | First, wear the test sample on the head mold specified by the standard according to standard requirements, and adjust it so that the heights on both sides of the hat hoop are consistent |
| Wearing height measurement | Measure the vertical distance from the lowest point of the bottom edge of the hat hoop on the side of the sample to the top of the head mold as the wearing height, record the measured value with an accuracy of 1mm |
| Measurement of X1 | Measure the vertical distance from the position of the point on the edge of the minor axis of the helmet shell relative to the head mold to the top of the helmet shell as X1 |
| Sample re - placement for X2 measurement | Remove the wearing system and cushioning liners, place the sample on the head mold again, and ensure that the posture of the helmet shell is the same as before removal |
| Measurement of X2 | Measure the vertical distance between the same points as X2 |
