What is Full-angle Leeb Hardness Tester? The full-angle Leeb hardness tester measures at any angle in accordance with the Leeb principle to calculate the hardness value, regardless of whether it is upward, downward or horizontal. The same measurement results are obtained for the same workpiece in ... Read More

Introduction Two-Box Hot and Cold Thermal Shock Chamber a. There are only two zones, the high temperature zone and the low temperature zone, and no test zone. Its "test zone" is a hanging basket, which is loaded with test samples and moves between the high temperature zone and the low temperature ... Read More

What is Hot and Cold Thermal Shock Test? The hot and cold shock test, also known as the temperature thermal shock test or the high and low temperature shock test, is used to assess the adaptability of the product to the rapid change of the ambient temperature. It is an indispensable test in the ... Read More

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
