Gloss is one aspect of visual perception, and considering the psychological impact of a product on consumers, it is equally important as color. Glossiness refers to the specular reflection of light on the surface of an object. Glossiness can be understood as the subtle “roughness” of an object’s surface. The smoother the surface, the more “reflective” it is, the brig...
What is Glow Wire Testing? Glow Wire Testing is used to test the stabilities of electronic and electrical products when in operation. The glow wire itself is a fixed-size coil of resistance wire and during the test, the resistive wire needs to be heated with electricity to a predetermined temperature so that the top of the glow wire can contact the sample for a predetermined period of time and t...
Introduction There is an urgent need for electrical equipment that is resistant to water. It is necessary to have IP waterproof testing equipment in order to conduct an exact analysis and provide a warranty about the water resistance of electronic devices. waterproof test Equipment The equipment used in IP testing has progressed in tandem with the introduction of new technology. This article dis...
Introduction Integrating spheres are often used in the process of optical measuring in order to get precise findings. Nevertheless, it is possible that the findings of the measurements will be affected by the size and form of the samples that are being evaluated. This article’s objective is to investigate the impact that sample size and shape have on the measurements obtained using an integr...
1. Briefly Interpretation of Cyclic Corrosion Test The cyclic corrosion test method is a newly developed method which can reflect the influence of natural environment exposure to sample materials, and is used by companies to formulate related standards. This method is preceded by constant salt fog test, spray-dry test and cyclic corrosion test, while salt fog ultraviole cyclic exposure test and ot...
Integrating Spheres can conveniently lumen measurement and test radiation power of light sources, thus it can be used for testing various lighting products. What is an integrating sphere? An integrating sphere, also known as a photosphere, is a hollow sphere with a highly reflective interior surface that is used as an efficient light-gathering device to collect the scattered or emitted light fro...

Electrical safety test equipments are used for high voltage component insulation test (with AC or DC withstanding voltage tester), such as silicon stacks. It is a special instrument mainly used to detect whether the product leaks electricity, has good grounding, and will not harm personal safety. The main testing items are voltage, leakage current, insulation resistance and grounding resistance. L...
Introduction: Testing for electrostatic discharge (ESD) is essential for guaranteeing the quality and functionality of electronic parts. However, engineers face a number of obstacles while conducting ESD tests, which must be overcome for reliable findings. ESD guns, with their unique set of features, have become indispensable in the face of these difficulties. This article discusses the many probl...
