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.
