Helmets Vertical SpacingInfrared - positioning Tester/ safety helmet vertical spacing tester / helmet fit measurement device
Purpose
This measuring instrument is used to measure the vertical spacing and wearing height of safety helmets.
Applicable Standard
GB/T 2812-2006
GB 2811-2019
Technical Parameters
1. Digital height gauge, which can display the height in real - time, with a measuring range of 0 - 500mm.
2. Adopts infrared positioning.
3. First, wear the test sample on the standard - specified head mold according to the standard requirements, and adjust it to make the heights on both sides of the hat hoop consistent.
4. 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 and be accurate to 1mm.
5. 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.
6. 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.
7. Measure the vertical distance between the same points as X2.
