Knowledge of the behavior of materials to repetitive temperature variations is vital in the design of durable products used in electronics, automobile, aerospace, and manufacturing industries. A temperature test chamber gives a controlled condition to expose materials to cyclic thermal stress and show the variation of mechanical, electrical, and structural characteristics over a period of time. A ...
With the growth of faster, smaller, more interconnected electronic systems, the control of unwanted electromagnetic emissions has become a major task of engineers. It is crucial to know what is EMI and its impact on the efficiency of the system during compliance testing and the development of a product. An EMI spectrum analyzer is vital in this process as it allows an in-depth analysis of interfer...
Automobile parts have to be subjected to extreme environmental conditions that include road salt, moisture, changes in temperature, and factory pollutants. In order to achieve an effective long term durability, manufacturers use a salt spray test chamber whereby they recreate the corrosive environments in controlled laboratory conditions. The salt spray fog test is very popular during automotive q...
The devices of electricity and electronic equipment which are attached to power and signal line are prone to the transient overvoltage occurrence as a result of lightning strike, switching in the grid, and inductive load interrupt. In order to test immunity to these disturbances, a 10kV surge generator that can reproduce controlled high-energy pulses is used to test immunity in laboratories. In pr...
Modern lighting design, compliance and performance validation require accurate assessment of luminous intensity distribution. The goniophotometer operation is the basis of this assessment as they allow the angular analysis with great precision of the light produced on luminaire. This is the core step in professional laboratories in light measurement, particularly in measuring fixtures that are pla...
The correct light output measurement is essential to determine the actual output of the current lighting products. An Integrating sphere is a dedicated device specialized to quantify total luminous flux in a controlled and repeatable fashion, and therefore used as a required apparatus in checking both initial output and long-term stability. The lumen sphere in illumination is important in professi...
Innovative products are supposed to perform in various weather conditions under extreme temperatures and humidity, high or low rates of climatic changes, as well as being exposed to stress in the course of many years. The issue is eradicated by means of an environmental test chamber through which the controlled laboratory solution will reproduce these conditions with repeatability and accuracy. At...
Proper measurement of undesired emissions is an essential need in the contemporary electronics. In compliance testing, the engineers are required to maintain emission within the limits required by legislations under standardized measuring conditions. An important constituent of this process is the electromagnetic test of interference, wherein the way of detection is indicated and evaluated in rega...
Effective assessment of corrosion is not only based on the length of exposure but the level of control of the test environment. A salt spray test is based on specifically controlled parameters to create the imitation of the aggressive corrosive environment, and even minor changes can distort an outcome. In an experimental corrosion test environment, calibration is used to assure that the temperatu...
