Universal Testing Machine

Instrument Details

Make               : Hydraulic & Engineering Instruments, New Delhi, India (HEICO)
Model              : HL 590.25
Specification : A universal testing machine is used to test the tensile stress and compressive strength of materials.

Universal testing machines (UTMs) that test mechanical properties such as tensile, flexural, compressive and shear. The UTM is a great multi-purpose instrument for an R&D lab. or quality control department.

Working Principles

Operation of the machine is by hydraulic transmission of load from the test specimen to a separately housed load indicator. The system is ideal since it replaces transmission of load through levers and knife edges, which are prone to wear and damage due to shock on rupture of test pieces. Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to the cylinder of the pendulum dynamometer system housed in the control panel. The cylinder of the dynamometer is also of self - lubricating design. The deflection of the pendulum represents the absolute load applied on the test specimen. Return movement of the pendulum is effectively damped to absorb energy in the event of sudden breakage of the specimen.

Applications

• Tensile Test
• Compression Test
• Bending Test
• Transverse Test

User Instructions

1. Testing should be carried out in accordance with the relevant standard or guidelines.
2. Fix upper and lower pressure plates to the upper stationary head &lower table respectively. Place the specimen on the lower plate in order to grip, then adjust zero.
3. Do not switch on the machine without connecting the point to the earth cable of the machine.
4. Care should be taken not to switch on main supply before plugging in cable connector.
