What is a Dust Test Chamber? A dust chamber is intended for performing different types of tests where the temperature of the sample environment must be controlled within certain limits. The dust test chamber is applied to physical and other related performance tests for electronic and electrical products, lamps, electrical cabinets, electrical components, automobiles, motorcycles and their parts. ...
The potential and advantages of LEDs continue to develop. The next five to fifteen years will be a period of development of LED lighting from traditional (alternative) lighting to revolutionary (humanized) lighting. The industry should pay attention to the trend of standards and meet the development of new industries. Opportunities and Challenges. In the standardization activities of our country, ...
The goniophotometer is an instrument that uses spectrophotometry to perform quantitative and qualitative analysis of substances. It is mainly used for the measurement of the light distribution performance of lamps and light sources, that is, the breadth of light sources in different directions of space, and the distribution of color measurement values. The spectrophotometric law is to determine th...

What is the test standard in IEC 60529? IEC 60529 conformance test is a popular entrance protection test standard. Entrance protection determines the ability of the chassis to protect its contents. Entrance test is applicable to solids and liquids. The protection level is called IP code. IP is the abbreviation of ingress protection. IP grade refers to the protection grade of electrical equipment ...
Sunlight is essential for plants, because plants need to rely on sunlight for photosynthesis. We all know that sunlight is a continuous spectral light source, and plant photosynthesis is mainly carried out in the visible spectrum. With the progress of science and technology, people gradually produce the corresponding standard light source according to the continuous spectral characteristics of nat...
What is the RoHS Test? You might have heard the term in conversations about compliance RoHS, or the restriction of hazardous substances is a European Union regulation that applies to electric and electronic equipment. The manufacture of these products involves the use of substances that could harm human health or the environment. It regulates the use of some substances like Mercury, Lead, and Cadm...
What is fundamental wave？ Fundamental wave The frequency of the voltage or current that changes periodically in the power network is the fundamental wave (also known as the primary wave). The specified frequency of our power grid is 50Hz, so the fundamental wave is 50Hz. What are harmonics？ Harmonic Wave Except for the fundamental wave (50Hz) in the power network, any periodic voltage or curre...
