How to conduct low-temperature impact test?Test Method

GB/T2423.1.2TheGB/T10592-2008TheGJB150.3High and low temperature impact test chamber.

?Product Introduction

High and low temperature impact testing machineIt is a testing equipment used in the metal, plastic, rubber, electronics and other material industries to test material structures or composite materials. It can withstand continuous temperature and extremely low temperature environments in an instant, and can detect chemical changes or physical damage caused by thermal expansion and contraction of samples in the shortest possible time.
