Safety Helmet Impact Acceleration Tester
The safety helmet impact acceleration tester is an instrument used to test the performance of safety helmets when subjected to impact. It can simulate the impact forces that safety helmets experience during events such as falling objects or collisions, thereby verifying whether they can effectively absorb energy and protect the head.
Application
This instrument is suitable for impact - collision tests of helmets. It is a testing instrument used to evaluate the impact - resistance performance of helmets. Meanwhile, it can also meet the requirements of penetration tests. Just replace the fixture, and it is easy to operate.
Standard
GB / T 2812-2006:Test method of safety helmet
GB / T 2811-2007:Safety helmet
Feature
Standardization and Ease of Use: Complies with GB/T2812 standard, simple operation, one-button start of the test, and automated process reduces human error.
Precise Measurement and Intelligent Control: Laser sensors accurately measure the distance between the impact head and the safety helmet, supporting custom height settings with an error of ≤1%.
High Precision and Reliability: IEPE sensor + laser positioning + digital display, achieving industry-leading data accuracy.
Intelligent Operation: Automatic adjustment, real-time data acquisition, and curve analysis significantly improve test efficiency and data value.
Safety Protection Design: Enclosed test chamber + sturdy machine body ensure the safety of operators and equipment.
Application Value: Provides scientific basis for manufacturing enterprises and quality inspection institutions, helping to optimize product design, improve product quality, and ultimately protect the lives of frontline workers.

Test Procedures
Equipment Preparation: Check the integrity of the equipment's power lines, confirm that the grounding protection device is effective, and ensure the hydraulic system oil level is above 80% of the scale.
Environmental Parameter Calibration: The laboratory temperature must be controlled at (20±2)℃, and the humidity should be below 60%.
Sample Installation Procedure: When fixing the safety helmet to the head form, ensure that the distance between the helmet shell and the head form meets the test standards, and adjust the tightness of the chin strap.
Test Operation: Press the "Tare/Zero" button on the control panel to eliminate the initial influence of the safety helmet's own weight on the force sensor.
Data Recording: Save the test results using the "Store" button on the control panel, or connect a USB flash drive to export the data (supports Excel/PDF format).
