The helmet vertical spacing infrared positioning tester is a specialized instrument used to measure the vertical spacing and wearing height of safety helmets. It conforms to the GB/T 2812-2006 "Safety Helmet Test Methods" standard, and some models are compatible with the updated GB/T 2812-2024 standard.
This measuring instrument is used to measure the vertical spacing and wearing height of safety helmets.
(1)GB/T 2812-2006: Test method of safety helmet
(2)GB 2811-2019: Head protection—Safety helmets
(3)EN 397: Protective helmets for industry
(1)Digital display: Uses a digital display scale for intuitive readings and to avoid human error.
Modular design: Supports the replacement of different head forms, adapting to various safety helmet sizes.
(2)Efficient and convenient: Automated measurement process improves testing efficiency.
(3)Compliant with standards: Strictly adheres to domestic and international safety helmet testing standards.
| 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 |

(3)Head model (including two specifications, #1 and #2. corresponding to different wearing height requirements)
(4)Digital display device (or touch screen control panel, used to display measurement data in real time)
(5)Loading device (used to apply a load of 50N ± 1N to stabilize the sample during testing)
Selecting the head form: Select the appropriate head form according to the standard. For example, use head form #1 when the wearing height is ≤85mm; use head form #2 when the wearing height is >85mm.
Installing the digital caliper: Fix the digital caliper to the selected head form using the given mounting holes.
Zeroing the caliper: Pull the digital caliper to the lowest position and press the zero button.
Adjusting the measuring feet: Measure the distance between the side headbands of the helmet and adjust the measuring feet to the appropriate length.
Wearing the helmet: Wear the helmet normally on the selected head form.
Measuring the data: Pull the digital caliper until the measuring feet touch the side headbands, read the value, and calculate the vertical distance and wearing height.
1. What is a Helmets Vertical Spacing Infrared-Positioning Tester?
This device is used to measure the vertical clearance and fit of helmets using infrared sensors, ensuring proper head coverage and safety compliance.
2. How does the infrared positioning test work?
The helmet is placed on a test fixture, and infrared sensors scan its interior and exterior. The system accurately measures vertical spacing, alignment, and clearance to evaluate proper fit and structural consistency.
3. What types of helmets can be tested?
It can test industrial safety helmets, bicycle helmets, motorcycle helmets, and other protective headgear designed to meet national or international safety standards.
4. What parameters are measured during testing?
The tester measures vertical spacing, clearance, alignment accuracy, and positional deviations. Some models provide digital readouts and automated data logging for quality control.
5. Why is vertical spacing infrared testing important?
Ensuring proper vertical spacing and fit guarantees maximum protection in case of impact, improves comfort for the wearer, and ensures compliance with safety standards such as EN 397. ANSI Z89.1. or ISO helmet standards.
