How to use this machine ?
Specimens are placed in the grips of a Universal Test Machine at a specified grip separation and pulled until failure. For special standard the test speed can be determined by the material specification or time to failure. An extensionmeter or strain gauge is used to determine elongation and tensile modulus if need. Depending upon the reinforcement and type, testing in more than one orientation may be necessary.
1. Application:
WDW series computerized electronic universal testing machines are designed and manufacture
according to ASTM, ISO, DIN, GB and other international standards. Applicable for wide range of material for tension, compression, bending, shearing and low cycle test. Suitable for metal, rubber, plastic, spring, textile, and components testing. It is widely used in the corresponding industries, research
and development, test institutes and training centers etc.
