​Glow Wire Testering Machine: The Guardian of the Safety and Quality of Electrical and Electronic Products

In modern science, technology, and industry, safety and quality have always been the cornerstone of enterprise survival and development. In the research and development, production, and quality inspection of electrical and electronic products, household appliances, and various insulating materials, the glow-wire tester silently guards the safety bottom line of these products.

Founded in 2012, Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. focuses on the research and development, design, and production of textile testing instruments, and provides textile testing instruments and services to academic research units and testing institutions. Shanghai Qianshi is currently one of the most competitive R&D textile testing instrument manufacturers in China. Its R&D team is composed of a group of experienced engineers who are committed to serving customers wholeheartedly and striving to promote technological innovation in textile testing instruments. This article will take you to a deeper understanding of the importance of the glow-wire tester in practical applications and the key links in the testing process.

1.Role Positioning

As a key tool for evaluating the flame retardancy of materials, the glow wire testering machine simulates the thermal stress generated by a glowing element or an overload resistor in a short period to test the reaction of the material under different conditions. It is not only used for flame retardancy testing of electrical and electronic products and their materials but is also widely involved in lighting equipment, low-voltage electrical appliances, motors, electronic instruments, and other industries. The effectiveness of this test method is directly related to the safety performance of the product and is an important part of preventing fires and protecting the safety of personnel and property.

2. Fine Operation of the Test Process

A standard glow-wire test, from preparation to completion, must follow strict operating procedures. First, the sample must be placed under specific environmental conditions (such as a temperature of 15℃ to 35℃ and a relative humidity of 45% to 75%) for 24 hours to ensure the stability and reliability of the test results. During the test, the glow wire is placed in the center of the sample and maintained at a depth of 7mm, ensuring that it does not penetrate the support of the sample. The test time is set to 30 seconds, during which the height, duration, and temperature of any burning flame, as well as the test environment, must be monitored and recorded in real time to comprehensively evaluate the flame retardancy of the material.

3. Uncertainty Analysis: Both Science and Rigor

In the glow-wire test, the assessment of uncertainty is also crucial. It is a quantitative characterization of the quality of the measurement results, which directly affects the accuracy and credibility of the test results. This analysis not only involves the accuracy of measuring instruments (such as thermocouples, timers, etc.) but also covers the skill level and experience judgment of operators. Through scientific classification and calculation, the accuracy and reliability of the test results are ensured.

4. Challenges and Responses in Practice

In practical applications, there are many challenges. On the one hand, different materials react differently to thermal stress, and test parameters need to be adjusted according to specific material properties. On the other hand, differences in the skill level and experience of operators may also affect the accuracy of test results. To address this, companies should strengthen the training of operators to improve their understanding and execution of test standards and operating procedures. At the same time, the selection of high-precision and high-reliability test equipment is also an important guarantee to ensure the accuracy of test results.

5. Conclusion

As the guardian of safety and quality, the glow wire testering machine plays an irreplaceable role in the research and development, production, and quality inspection of electrical and electronic products and their materials. It not only provides enterprises with scientific and reliable testing methods but also provides strong support for product safety design and evaluation. With the advancement of science and technology and the development of industry, its performance and accuracy will continue to improve, contributing to safety and quality assurance in more fields. In the days ahead, let us look forward to even brighter development prospects for this important testing tool.
