Needle flame combustion tester is a kind of special equipment for evaluating the combustion performance and flame retardant properties of materials under needle flame conditions. It is mainly used to test the flame retardant properties of electronic and electrical products, electrical accessories, plastics and other solid materials, and is widely used in electronic and electrical appliances, lighting equipment, household appliances, automobiles, aerospace and other fields. The following is the detailed introduction of needle flame combustion tester:
I. Main Uses
1.Flame retardant performance test: to assess the burning behavior of materials under needle flame conditions, including burning time, burning range, flame spread speed, etc..
2.Quality control: In industrial production, it is used for quality control of raw materials and finished products to ensure that the products meet the flame retardant standards.
3.Certification testing: Used in product certification testing to ensure that the products comply with international and national standards, such as IEC, UL, GB and other standards.
4.R&D and Improvement: In the R&D stage, it is used to evaluate the flame retardant properties of new materials and products, and to guide product design and improvement.
II. Working Principle
The needle flame combustion tester evaluates the flame retardancy of materials by simulating small flames (such as a lit needle flame) to conduct combustion tests on the materials. The specific steps are as follows:
1.Sample preparation: the sample to be tested is cut and pre-treated according to the standard requirements.
2.Fixing the sample: Fix the sample on the sample holder of the testing machine to ensure that the sample is in the specified position and angle.
3.Ignition: The sample is ignited using a needle flame of specified size and shape, usually a mixture of gas (e.g. propane) and air.
4.Combustion Test: The sample is burned for a specified period of time, and the combustion behavior of the sample is observed and recorded, including combustion time, combustion range, and flame spread rate.
5.Evaluation of results: According to the standard requirements, the burning behavior of the sample is evaluated to determine whether it meets the flame retardant standards.
Cautions
1.SAFE OPERATION: Safety regulations should be strictly observed during operation to avoid gas leakage, fire and other dangerous situations.
2.Sample Preparation: The sample should be cut and pre-treated according to standard requirements to ensure that the size and shape of the sample meet the requirements.
3.Environmental conditions: the instrument should be placed in a well-ventilated environment with suitable temperature to avoid environmental factors affecting the test results.
4.Periodic calibration: The instrument should be calibrated periodically to ensure the accuracy of flame temperature, size and gas flow.
5.Personnel training: Operators should be professionally trained and familiar with the operating procedures and safety precautions of the instrument.
Frequently Asked Questions and Answers (FAQ) of Needle Flame Combustion Tester
1. What is a needle flame combustion tester?
Needle flame combustion tester is a special equipment for evaluating the combustion performance and flame retardant properties of materials under the condition of needle flame. It evaluates the flame retardant properties of materials by simulating a small flame for combustion testing, and is widely used in the fields of electronic and electrical appliances, lighting equipment, automotive, aerospace and so on.
2. What is the testing principle of needle flame combustion tester?
The needle flame combustion tester ignites the sample by using a needle flame of specified size and shape, and observes and records the combustion behavior of the sample within a specified period of time, including the combustion time, combustion range, and flame spreading speed. The flame retardancy of the material is evaluated based on these parameters.
3. What international standards does the Needle Flame Tester meet?
Needle flame combustion testers typically comply with the following international standards:
- IEC 60695-11-5: International Electrotechnical Commission (IEC) standard that specifies the technical requirements and test methods for needle flame burning testers.
- UL 94: Underwriters Laboratories (UL) standard, which specifies the test methods for flame retardancy of plastic materials.
- GB/T 5169.5-2008: China's national standard, which specifies the test method for fire hazard of electrical and electronic products.
4. How to prepare the test samples for Needle Flame Tester?
Test samples should be cut and pre-treated in accordance with relevant standards to ensure that the size and shape of the samples meet the requirements. Samples usually need to be clean, dry, and fixed in the sample frame of the test machine, the sample and the horizontal plane angle is usually 45 .
5. What is the flame temperature of a needle flame combustion tester?
The flame temperature of needle flame combustion tester is usually 100050, the specific temperature can be adjusted according to different standards and requirements. The instrument is equipped with a high-precision temperature sensor for real-time monitoring and control of the flame temperature.
6. How long is the test time of needle flame combustion tester?
The test time is usually 30-60 seconds, depending on different standards and requirements. The instrument is usually equipped with an automatic timing function to ensure the accuracy of the test time.
7. What type of gas is used in a needle flame tester?
Needle flame combustion testers typically use propane as the gas. The mixing ratio of gas and air is regulated by a precision control system to ensure flame stability and consistency.
8. What are the safety devices in a needle flame combustion tester?
Needle flame combustion testers are equipped with multiple safety devices, including:
- Flame monitor: monitors the flame status to ensure flame stability.
- Gas leakage alarm: detects gas leakage and alarms in time.
- Emergency stop button: stop the test immediately in case of emergency.
- Explosion-proof device: to prevent the oxygen bomb explosion and other dangerous situations.
