Environmental testing refers to exposing products or materials to specific conditions, either natural or artificial, to evaluate their performance under realistic storage, transportation, and usage scenarios. This type of testing is crucial for ensuring product quality and performance. High-low temperature test chambers typically involve three main types of testing: natural exposure testing, field...
Electromagnetic Compatibility Testing (EMC): Ensuring Smooth Operation of Devices Electromagnetic Compatibility Testing (EMC) refers to the ability of devices or systems to operate in their electromagnetic environment in compliance with specified requirements and without causing unacceptable electromagnetic interference to surrounding equipment. EMC design and testing are complementary processes, ...
The high and low temperature test chamber is an essential device for conducting reliability tests on industrial products. It simulates high and low temperature environments to examine the performance indicators of various products, including electronic appliances, automotive components, aerospace equipment, and marine weaponry. The principle behind the operation of the high and low temperature tes...
What is Electrostatic Discharge (ESD)? Electrostatic Discharge (ESD) is one of the common sources of interference in electronic devices. According to the national standard GB/T17626.2 (equivalent to the international standard IEC61000-4-2), Electrostatic Discharge (ESD) Immunity TestingESD immunity testing is an essential step to ensure devices are protected from the disruptive effects of electros...
Introduction: The spring impact hammer, also known as a spring impactor, is an instrument used for impact testing. It releases a specific amount of impact energy through an internal impactor, applying it to the surface of the specimen, thus facilitating impact performance testing of materials or products. Applications and Standards: The spring impact hammer is designed and manufactured according t...
The ozone aging test chamber is designed specifically to simulate and test the aging performance of materials in an ozone environment. Widely used in the research, production, and quality control of polymer materials such as rubber, plastic, and coatings. This article provides a detailed overview of the ozone aging test chamber’s basic principles, technical parameters, usage methods, and pre...
Gloss measurement is conducted using a gloss meter, also known as a glossometer, which is an instrument designed to measure the surface specular reflectance (gloss). Gloss is determined by projecting a beam of light onto a surface with fixed intensity and angle and measuring the amount of reflected light at an equal but opposite angle. The method of gloss measurement is based on the principles of ...
In 2020, a global outbreak of the pandemic resulted in a shortage of protective equipment such as masks, primarily due to the scarcity of one of the main raw materials, melt-blown fabric. As a consequence of the melt-blown fabric shortage, some individuals began attempting to produce their own, leading to varying qualities of melt-blown fabric products in the market. Against the backdrop of intens...
The particle filtration efficiency tester is a specialized instrument used to assess the filtration efficiency of products such as air purifiers, masks, and automotive air purifiers. Its role is to ensure that these products effectively filter out harmful particles and gases from the air, thereby protecting people’s health. The principle of the particle filtration efficiency tester is based ...
