The flame test is one of the commonly used methods to evaluate the fire danger of electrical and electronic products. GB/T 5169.5-2020 “Test Fire Five – Test Flame Needle Flame Test Method Equipment, Confirm Test Method and Guide” as the latest version of the standard, after four revisions, clearly defines the purpose of the test is to determine that under the specified condition...
With the development of science and technology, more and more people begin to pay attention to the detection of color quality, especially in industries such as coatings, fabrics, packaging, building materials, plastics, and electronic products. In order to meet the various needs of customers, portable spectrophotometer is a common color detection instrument that has been widely used in more indus...
The Temperature Humidity Chamber is a kind of humidity testing equipment , used to test the range of material structure and composite materials that can be tolerated in a continuous environment of extremely low temperature or high temperature, and to test the chemical change damage caused by thermal expansion and contraction. instrument. Equipment capable of testing correctly for chamber temperat...
High and low temperature chambers are widely used in various industries such as electronics, electronics, aviation, chemical, military, etc. However, the testing requirements for products in different industries are not the same. So how to choose the appropriate high and low temperature chamber equipment for oneself? Temperature range selection: In order to meet the testing requirements of differ...
I.Electric equipment’s reaction to lightning surge Most people are familiar with the existence of a lightning surge generator. It is mainly used to evaluate the surge resistance of railway signal equipment connected to the power line. But do you know what the implications of a lightning surge would be for electronic devices? Here is a brief explanation of the effect a lightning surge can have on...
Introduction When designing and developing electrical equipment, electromagnetic compatibility (EMC) considerations must be given considerable attention. It is essential to check that electronic devices perform as anticipated in the electromagnetic environment to which they are exposed. Spectrum analyzers are an essential component of EMC testing, and they allow engineers to investigate and evalua...
Introduction Voltage spikes, also known as transient overvoltages, pose a particular threat to electrical and electronic equipment because of their susceptibility to them. These sudden increases in voltage only persist for a few seconds and may be brought on by a variety of factors, including lightning, switching processes, or difficulties with the power system itself. Surge generators, which are ...
The UV aging test chamber is mainly used to simulate the destructive effects of sunlight, humidity, and temperature on materials. The ultraviolet aging test chamber simulates sunlight, condensation, and natural humidity. The sample is tested in a simulated environment for a few days or weeks, which can reproduce the damage that may occur outdoors for several months or years. Application of UV agi...
ESD is the abbreviation of Electrostatic discharge, which stands for electrostatic discharge. It refers to a sudden electric current between two objects with different electric potentials. This current flow occurs when an object builds up static electricity and comes into contact with another object that has a different electrical potential. ESD can be generated by various sources such as frictio...
