What is a glow wire testing machine?
In recent years, with the continuous improvement of safety standards for electronic and electrical products, the glow wire testing machine, as an important testing equipment, has received widespread attention. This article will introduce in detail the definition, working principle, application fields and related technical parameters of the glow wire testing machine, and combine it with the hot topics on the Internet in the past 10 days to help readers fully understand this equipment.
1. Definition of glow wire testing machine
The glow wire testing machine is a testing equipment used to simulate the overheating conditions that electronic and electrical products may encounter under fault conditions. It evaluates the flame retardant properties of the material by heating a glowing wire of a specific material to a high temperature and contacting the material being tested to observe whether it ignites or burns.
2. Working principle
The working principle of the glow wire testing machine mainly includes the following steps:
| steps | Description |
|---|---|
| 1. Heating | Heat the glow wire to a preset temperature (usually 550°C to 960°C). |
| 2. Contact | The glow wire is contacted with the surface of the material being tested at a specific pressure for a certain period of time. |
| 3. Observe | Record whether the material is ignited and the duration of the burning. |
| 4. Evaluation | Determine the flame retardant grade of the material based on the test results. |
3. Application fields
Glow wire testing machines are widely used in the following industries:
| Industry | Specific applications |
|---|---|
| Electronic appliances | Evaluate the flame retardant properties of plastic housings, circuit boards and other materials. |
| automobile manufacturing | Test interior materials for fire safety. |
| building materials | Test the flame retardant properties of insulation materials and decorative materials. |
| Aerospace | Evaluate the fire performance of aircraft interior materials. |
4. Technical parameters
The following are common technical parameters of glow wire testing machines:
| parameters | Typical value |
|---|---|
| temperature range | 550℃～960℃ |
| Glow wire diameter | 4mm |
| contact time | 30 seconds |
| pressure | 1N±0.2N |
