Testing Machine

 

1. Introduction

 

This WAW-G Series Computerized Electro-hydraulic Servo UTM is our second generation UTM with high configuration and high testing accuracy. It is widely used for tensile, compression, bending and shearing test for metal materials, like steel, alloy, aluminum, etc. With special accessory, it can also be used for mechanical property test of fastener, steel wire rope and components. The machine is calibrated according to ISO 75001 and ASTM E4. It can do many different kinds of test according to different standards, ISO6892, ISO7438, ASTM A370, ASTM E8 and BS EN standards.
