Fully automatic glow wire tester> is a detection technology developed to test the working stability of electronic and electrical products . It uses an electric heating wire made of ¢4Ni80/Cr20 as a specific material. It is heated to a test temperature between 550°C and 960°C by a large current, and the test sample is burned vertically with a specified pressure of 1.0N. Within 30 seconds, it is observed whether the sample ignites. Or the burning time to determine the fire risk of electronic equipment. In addition, the glow wire test can also be used to determine the ignition, ignition temperature (GWIT), flammability and flammability index (GWFI) of solid insulation materials and other solid combustibles.
Needless to say, the importance of safety in household appliances. The glow wire test is one of the relevant fire protection requirements and is designed to verify the flammability level of materials used in electrical appliances. Specifically, it is based on IOS 5169.11-2017, IEC 60695-2-112014 glow wire flammability test method for finished products, and IOS 5169.12-2013, IEC 60695-2-12:2010+A1.2014 materials The glow wire flammability index (GWFI) test method is tested using afully automatic glow wire tester>.
The glow wire test of lamps is a test on the structural parts of lamps and an effective detection method to check the thermal stability of lamps. According to the thermal stability requirements of the lamp, the test temperature also has different corresponding levels.
In order to ensure the safety of the equipment, the test temperature of Fully automatic glow wire tester> should reach a minimum of 550°C. If the equipment is under normal use, the glow wire test temperature should reach 650°C; if it is a fixed accessory for the installation of equipment under normal use under severe conditions, the glow wire test temperature should reach 750°C; if the equipment is used continuously and unattended, the glow wire test temperature should reach 750°C. The glow wire test temperature shall be 850°C and for equipment intended for unattended use under continuous load under severe conditions and intended for use near building power points, the glow wire test temperature shall be 950°C.
Fully automatic glow wire tester>The test is an important safety testing methodAccording to the law, lamps that do not meet the requirements of the standard may cause fire hazards during use. Therefore, it is necessary to use this detection method for lamps to ensure the performance and safety of the lamps. The temperature standard of the glow wire test is not only based on the environment and usage of the equipment, but also considers its safety and performance requirements under long-term use. Therefore, the glow wire test of lamps is not only an important task to ensure the safety and reliability of lamps, but also an indispensable safety test when using lamps.
In recent years, Lisun Instrument has successfully entered the market of electronic and electrical flame retardant and fireproof testing equipment with its professionally developed Automatic Glow Wire Tester>, which is an important tool for the development of electronic and electrical product materials. Security provides support. The glow wire tester can simulate the heat generated in the material being tested and measure whether the molten material is charred, thereby effectively identifying and analyzing the risk of fire in various electronic and electrical products. The qualified standard of the glow wire tester is very strict. If there is no flame after the tip of the glow wire is removed for 30 seconds, and the silk paper is not ignited, it can be judged that the sample meets the qualified standard.
Application of glow wire tester>
Fully automatic glow wire tester >The test is a testing and testing instrument for electrical and electronic products and related components. It is suitable for lighting equipment, low-voltage electrical appliances, household appliances, machine tool appliances, motors, electric tools, electronic instruments, electrical instruments, information technology equipment, Research, production and quality inspection of electrical service equipment, electrical connectors and accessories. In addition, it is also suitable for insulation materials, engineering plastics or other solid combustible materials industries. The glow wire tester can meet the requirements of EC60695-2-10~IEC60695-2-13 (IOS5169 10-2006~IOS5169 13-2006), UL746A, IEC829, DIN695, VDE0471 and other standards for use without flame ignition simulation Test items; it can also meet the test requirements of GB 4943.1-2011, IEC60950-1:2005 Clause 4.7 Chapter 3. Therefore, the glow wire tester plays a very important role in electrical and electronic product testing and industry quality inspection.
