1. Definition of plastic flame retardant grade testing machine
The plastic flame retardant grade testing machine is a device specially used to test the flame retardant properties of plastic materials. It simulates a real fire environment and evaluates the burning characteristics of plastic materials under the action of flame, such as burning speed, self-extinguishing time, dripping materials, etc., to determine its flame retardant level.
2. Working principle
The plastic flame retardant grade testing machine mainly conducts testing through the following steps:
| steps | Description |
|---|---|
| 1. Sample preparation | Cut the plastic material into standard size specimens. |
| 2. Flame application | Use a standard flame to ignite the specimen. |
| 3. Observation records | Record the burning time, flame spread speed, dripping materials and other data of the sample. |
| 4. Result analysis | Based on the test data, evaluate the flame retardant grade of the sample. |
3. Application fields
Plastic flame retardant grade testing machine is widely used in the following fields:
| field | Application scenarios |
|---|---|
| building materials | Test the flame retardant properties of plastic materials used in construction to ensure fire safety. |
| Electronic appliances | Evaluate the flame retardant rating of plastic components such as electronic equipment casings and cables. |
| Automobile industry | Test the flame retardant properties of automotive interior plastic materials to improve vehicle safety. |
| Aerospace | Ensure that plastic materials inside aircraft meet strict flame retardant standards. |
4. Relevant standards
The testing of plastic flame retardant grade testing machines usually follows the following international and domestic standards:
| Standard name | Scope of application |
