What is a safety helmet testing machine?
In industrial production, construction sites and various high-risk working environments, safety helmets are important equipment to protect workers' head safety. The helmet testing machine is a device specially used to test the performance of helmets to ensure that they meet the requirements of national or international standards. This article will introduce in detail the function, classification, test items and related data of the helmet testing machine to help readers fully understand this key equipment.
1. The function of safety helmet testing machine
The helmet testing machine is mainly used to simulate the extreme conditions such as impact, puncture, high temperature resistance, and low temperature resistance that the helmet may encounter in actual use, and to verify its protective performance through scientific testing. The following are its main functions:
1.ensure security: Through testing, verify whether the helmet can effectively reduce impact force and prevent puncture by sharp objects.
2.Meet standards: Help manufacturers and regulatory authorities confirm whether products comply with national standards (such as GB 2811-2019) or international standards (such as EN 397).
3.Improve product quality: Optimize the design through test data to improve the protective performance of the helmet.
2. Classification of safety helmet testing machines
According to different test items, safety helmet testing machines can be divided into the following categories:
| Type | Function | Applicable standards |
|---|---|---|
| Impact testing machine | Simulate the impact of falling objects on helmets | GB 2811-2019, EN 397 |
| Puncture testing machine | Test the helmet's resistance to puncture by sharp objects | GB 2811-2019, ANSI Z89.1 |
| High temperature resistance testing machine | Test the performance of safety helmets in high temperature environments | ISO 20471 |
| Low temperature resistance testing machine | Test the performance of safety helmets in low temperature environments | ISO 20471 |
3. Test items of helmet testing machine
Hard hat testing machines usually include the following core test items:
| test items | Test method | Qualification standards |
|---|---|---|
| Impact absorbing properties | Drop a heavy object from a specified height and measure the impact force | Impact force ≤4900N |
| Puncture performance | Falling from a height with a cone-shaped object to puncture the helmet | Do not touch the headform |
| High temperature resistance | Place the helmet in an environment of 50℃ for 4 hours | No obvious deformation or performance degradation |
| Low temperature resistance | Place the helmet in an environment of -20℃ for 4 hours | No obvious deformation or performance degradation |
4. Technical parameters of safety helmet testing machine
The following are the technical parameters of a typical helmet testing machine:
| parameters | numerical value |
|---|---|
| impact height | 1m±5mm |
| Impact hammer weight | 5kg±0.01kg |
| Puncture cone weight | 3kg±0.01kg |
| temperature range | -40℃ to 100℃ |
| Test accuracy | ±1% |
5. Application fields of safety helmet testing machine
Safety helmet testing machines are widely used in the following fields:
1.Safety helmet manufacturer: Used for product development and quality control.
2.Quality inspection agency: For third-party testing and certification.
3.construction site: Used to regularly check the performance of helmets.
4.Scientific research unit: Used for testing and research of new materials and new technologies.
6. Summary
The helmet testing machine is the key equipment to ensure the performance of the helmet. Through scientific testing methods, it ensures that the helmet can effectively protect users in high-risk environments.
