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...
Abstract The Burning Test refers to a comprehensive series of standardized experimental methods used to scientifically evaluate a material’s ability to resist flame spread, maintain its structural integrity, and prevent fire expansion under specific ignition conditions. In the automotive industry, the flammability testing of interior materials is paramount, directly impacting occupant safety...
Exposure to water has become one of the leading factors of failure of the electronic and mechanized commodities which are either being used in the outdoor or humid environments. Consumer electronics, lighting fixtures and industrial enclosure and automotive manufacturers have to make sure that products do not lose their functionality once they are exposed to water in different conditions. The wate...
Abstract The spectrum analyzer, a core testing instrument in the RF and microwave engineering fields, plays a key role in converting time-domain electrical signals into frequency-domain spectra, visually displaying the signal’s frequency components and power distribution. This article aims to systematically answer the fundamental question: “What is a Spectrum Analyzer Used For?“....
Thermal stress analysis is an important tool in establishing the behavior of materials, electronics, and mechanical assemblies at excessive temperatures. The temperature test chamber will be set in such a way that controlled heating and cooling cycles are applied to the chamber which simulate harsh operating conditions during actual operation. These systems are nowadays used as a laboratory-specif...
Abstract X-ray fluorescence spectroscopy is a highly efficient, non-destructive elemental analysis technique widely used in material identification, quality control, and resource exploration. While traditional benchtop x-ray fluorescence machines offer exceptional accuracy, their fixed laboratory nature struggles to meet the demands for rapid on-site testing. Advances in detector technology, micro...
One of the most unpredictable failures in the modern electronics is the electrostatic discharge. The smaller, faster and denser the device, the lower the components capability of surviving high-voltage pulses. This ensures ESD testing is an important process in the product validation process particularly when the consumer requirement entails reliability in various settings. Economic factors like a...
