If you want to find a capable and reliable indicator light production company, you need to review the factory’s international certification. The more certifications they produce, the more reliable the quality of the indicator light they produce. You also need to see if they have the following certifications: ISO90001 quality management system certification, indicator light waterproof certification, indicator light UL certification, indicator light environmental certification, indicator light VDE certification, etc. Among them, the gold content of the indicator light UL certification is very high.
The following introduces the standards and requirements of each test
1、Withstand voltage test, the international standard for the withstand voltage test of LED indicators is 1800V, especially those with a voltage exceeding 220V must pass the 1800V withstand voltage test. If it fails to pass, there will be a possibility of leakage, and a long time may cause the mixed power of the LED indicators to burn out.
2、Aging test, the aging test of LED indicators simulates the normal use of LED indicators on the machine. If there is a problem with the LED, resistance, or other components of the LED indicators, the problem can be found through the aging test, and then the problem can be analyzed and solved so that the problematic LED indicators will not flow to the market.
3、High-temperature test, The high-temperature test is to simulate the entire LED indicators in a high-temperature box. For example, in the case of 150 degrees, the resistance LED or plastic or wires melt will eventually lead to the damage of the led indicators.
4、Low-temperature test, if the temperature is below 40 degrees, will all the materials and LEDs of the led indicators cause problems?
5、The salt spray environmental protection test is to check whether some metal materials of the LED indicators pass the environmental protection test, usually within 48 hours. If it passes, it proves that the material of the LED indicators is environmentally friendly. If it fails, it means that the material of the LED indicators is not up to the standard. Environmental protection standards.
6、Waterproof test, many LED indicators will be placed outdoors, on a boat, or in the kitchen. The requirements for waterproofing are still quite high. You can know whether the LED indicators are waterproof through the waterproof test.
7、Tensile test, many LED indicators with wires fall off after using wires. Therefore, a tensile test must be used to check the firmness of the connection between the LED indicators and the wires. The tensile force is usually about 10KG.
The products that have passed the indicator light test project are generally more reliable.
The factory that has passed this certification must have a standard indicator light testing laboratory, and the chances of producing good quality products are very high.
