The conditions in the modern automotive and aerospace systems are so harsh that they subject materials, electronic and mechanical assemblies to the supreme strain. Temperature variations, pressure, vibration and protracted exposure to adverse weather conditions may all degrade performance in case parts are not validated appropriately. A fundamental instrument in this validation process is environm...
Electrostatic discharge is also one of the most hazardous and destructive dangers to present-day electronic circuits. With the shrinkage, quicker, more complexified devices, even the slightest discharge, whether low-energy or not, will cause system problems, overwritten data, or irreversible damages. ESD test equipment is uniquely cultured to determine the sensitivity of circuits to electrostatic ...
The most difficult of the electronics designs to design in terms of electromagnetic compatibility are switching power supplies and SMPS-based circuits. High switching frequencies, short edge transitions and small layouts tend to produce conducted and radiated noise which can readily exceed administrative limits. The EMI-9KB has taken significance in this regard since it enables engineers to detect...
The glow wire test standard is the most broadly applied test to determine the ignition resistance of insulating materials, plastics and enclosure parts subjected to overheating electrical parts. Since such tests directly correspond to the risks of a fire, the accuracy of equipment is essential. Compliance wise, proper maintenance of glow wire tester should make the reference of glow wire flammabil...
The reliability of corrosion testing is dependent on the precision of the machine that does the test. A salt spray test machine is created so as to provide controlled corrosive environment simulating long time exposure to saline atmospheres but without proper calibration, the results of such tests rapidly lose credibility. The parameters by which the salt spray corrosion tester must work in the pr...
The contemporary electronic equipment should be usable in the conditions when electric problems cannot be avoided. Any activities involving switching of power, lightning-induced transients, relay activities and inductive loads trigger voltage surges on sensitive circuits in the short term that may cause circuit brown-out or damage. A burst surge generator is a specially constructed device to recre...
Products that are to be used outdoors, in industrial, military or desert conditions must show good performance under the exposure of airborne particles. These deplorable conditions can be reproduced in controlled laboratory conditions in a sand dust test chamber which enables manufacturers to check sealing integrity, mechanical durability, and functional reliability. The IEC 60529 dust test define...
Proper testing of performance of lighting is the key to product safety, efficiency and acceptance regarding regulations in the global market. Goniophotometry is of a central importance in the process as they offer a detailed analysis of light distribution, and light intensity by the aid of a highly controlled instrument for measuring light intensity able to capture directional photometric data. In...
Precise optical measurements require the capability to acquire the light yield correctly, or repeatably. This is common with a sphere light source which is an integrating source since it modular directional light into a diffuse and uniform light source which can be measured accurately. In practice within laboratory settings, the system is commonly known as a photometric sphere with its primary use...
