UN 38.3 Ensuring Safe Transportation of Lithium Batteries T6 – Impact / Crush The impact and crush tests are designed to simulate a packaging failure or mishandling during shipping. These tests are only applicable to cells, and the choice of test depends on the cell's geometry. The impact test is ... Read More

What is Bainite Microstructure? Bainite is a mixed microstructure in steel that forms at intermediate temperatures between high-temperature pearlite and low-temperature martensite. It's mainly made up of supersaturated ferrite and carbides or carbon-rich retained austenite. Traditional metallography ... Read More

Difference Between Microhardness and Vickers Hardness 1. Different test force: This is the main difference between microhardness and Vickers hardness. The test force of microhardness is usually small, up to 2kg. The test force of Vickers hardness is large, up to 50kg (some Vickers hardness testers ... Read More

What is Metallographic Analysis? Understand the principles and application areas of metallographic analysis Metallographic analysis refers to a method of studying the internal structure of metal materials by microscopic observation and analysis of metallographic microphotography. It mainly relies on ... Read More

Temperature and Humidity Fluctuations in Climate Chamber In order to more accurately simulate the actual environmental conditions that the product is subjected to in nature, the environmental test must ensure that the tested product is in the same temperature environment. To this end, the temperatur... Read More

What is Barcol Durometer? The unit of Barcol hardness tester is bar (Ba). One Barcol hardness unit is equal to the force applied by the indenter when it presses into the material being tested by one millimeter. The calculation formula of Barcol hardness tester is: Ba = 0.1mm × g / F, where Ba is the ... Read More

What is Cryptocrystalline Martensite? Cryptocrystalline martensite is a microstructural morphology of martensite. Its main feature is that, when observed under a metallographic microscope, there are no obvious needle-like or bamboo-leaf shapes, but rather a blurry, darker-colored area that seems to ... Read More

Selection of Control Method for Simulated Climate Chamber There are two types of temperature and humidity environmental test chambers: constant test chambers and alternating test chambers. Generally speaking, high and low temperature environmental test chambers refers to constant temperature, and ... Read More

What is deformation in metal materials? When metal materials are subjected to external forces and their shape and size change, this is called deformation. Material deformation includes plastic deformation and elastic deformation. For materials that deform, if the deformation disappears when the ... Read More

Select Humidity Range of Climate Chamber The humidity index given by the temperature and humidity environment test chamber is mostly 20%~98% or 30%~98%. If the temperature and humidity environment test chamber does not have a dehumidification system, then the test chamber with a humidity range of 60... Read More
