The needle flame tester mainly has the following characteristics:
1. In terms of structural design
Excellent material manufacturing: The outer shell and important components of the test chamber are usually made of stainless steel, which has good smoke and gas corrosion resistance. It is not only sturdy and durable, but also easy to clean and maintain, and can adapt to long-term and frequent testing environments, extending the service life of the equipment
Integrated design: The testing and control parts of the tester are often designed in an integrated manner, which facilitates on-site installation and debugging, reduces the equipment's footprint, improves space utilization, and makes the overall structure of the equipment more compact and aesthetically pleasing
2. In terms of testing accuracy
Correct flame control: Using needle shaped burners of specific sizes, such as those with an outer diameter of no more than 0.9mm, a height of at least 35mm, and an aperture of 0.5mm ± 0.1mm, can produce stable and correctly controllable flames. The flame height can be adjusted to 12mm ± 1mm, the flame application angle can be adjusted to 0 ° and 45 °, and the gas flame temperature gradient is (100 ± 5) ℃~(700 ± 3) ℃. The time required to rise from 100 ℃ to 700 ℃ is 23.5 seconds. It can accurately simulate small flames generated under various fault conditions, ensuring consistency and correctness of testing conditions
High precision sensors and measurement system: equipped with imported K-type armored thermocouples and other high-precision sensors, with a stainless steel tube with a diameter of 0.5mm as the sheath, it can accurately measure key parameters such as flame temperature, sample combustion time, and combustion length. The measurement accuracy is high and the error is small, providing reliable data support for evaluating the combustion performance of materials
3. In terms of automation and intelligence
Highly automated control: By using a good embedded computer control or PLC logic controller, a fully intelligent control method can be achieved, which can achieve automatic control of the test program, including automatic ignition, flame calibration timing automation, ignition holding time timing and other functions, greatly improving the testing efficiency and reducing manual operation errors and interference
Humanized operation interface: equipped with Taiwan Weilun seven inch TFT true color LCD touch screen, etc., the operation interface is intuitive, simple, and easy to operate, which can upgrade the customer's humanized operation interface and achieve international comparison results. Users only need to follow the prompts for simple settings and operations to complete the test, without professional skills and complex operation experience
4. Data processing and recording aspects
Data display and recording are intuitive and correct: Test data such as temperature and time are displayed digitally, which is clear, intuitive, and easy to observe and record. At the same time, the device can automatically record various data during the testing process, such as combustion time, flame spread speed, etc., and generate test reports as needed. The test reports can be automatically numbered, stored, and printed, making it convenient for users to query, analyze, and manage the test results
Powerful data processing and analysis capabilities: The computer control system can perform real-time processing and analysis of test data, such as calculating combustion rate, evaluating combustion level, etc., and visually display the results in the form of charts, curves, etc., providing users with detailed and accurate evaluation criteria for material combustion performance, helping users better understand the combustion characteristics of materials, and providing strong support for product design, research and development, and quality control
5. In terms of safety performance
Independent exhaust system: equipped with an independent exhaust system, it can timely and effectively exhaust the smoke and harmful gases generated during the testing process, maintain the cleanliness and good ventilation of the testing environment, not only protect the health of operators, but also avoid the influence of smoke and harmful gases on the test results, ensuring the correctness and reliability of the test
Multiple safety protection measures: Equipped with automatic shutdown devices and other multiple safety protection measures, the equipment can automatically cut off the gas source and stop testing in case of abnormal situations such as flame loss, high temperature, gas leakage, etc., ensuring the safety of the testing process and preventing fires or other safety accidents
6. Scope of application and standardization aspects
Widely applicable scope: Suitable for research, production, and quality inspection departments of electrical and electronic equipment and their components such as lighting, low-voltage appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical instruments, information technology equipment, electrical affairs equipment, electrical connectors, accessories, etc. It is also suitable for insulation materials, engineering plastics, or other solid combustible materials industries, and can meet the needs of different industries and fields for material combustion performance testing
Compliant with relevant standards: Compliant with GB/T5169.5-2008 "Fire hazard testing for electrical and electronic products - Part 5: Test flame needle flame test method, apparatus, confirmation test method and guidelines" and other relevant standards, ensuring the correctness and comparability of test results, providing reliable basis for product quality control and safety evaluation
