Servo Hydraulic Universal Testing Machines are widely used for tension, compression, bending and shearing test of metal materials and also used for compression and bending test of nonmetal materials, such as cement, concrete and so on.
Equipped with simple accessories, it can be used for mechanical property testing of fastener, wire rope and components. They are perfect testing instrument project quality testing section, universities and colleges, research institution and industrial and mining enterprises. The machine is calibrated according to ASTM E4 and ISO7500-1.
It can do many different kinds of test according to according to ISO6892, ISO7438, ASTM A370, ASTM E8 and BS EN standards.

Frequently Asked Questions: Servo-Hydraulic Universal Testing Machines
1. What materials can be tested with a Servo-Hydraulic Universal Testing Machine?
These high-capacity systems are designed for heavy-duty testing of high-strength materials. They are commonly used for metals (steel reinforcement bars, alloys, and structural components), composites, large fasteners, and concrete. They can perform tensile, compression, bend, and shear tests.
2. What is the advantage of a Servo-Hydraulic UTM over an Electromechanical system?
Servo-hydraulic systems are preferred for high-force applications (typically above 300kN to 2000kN+). They provide superior durability for high-cycle fatigue testing and offer a more compact footprint for the massive force capacities required in industrial and construction material testing.
3. Which international testing standards do these machines comply with?
The IDM Instruments range is engineered to meet or exceed major global standards, including:
• ISO 6892 & ASTM E8: Metallic materials tensile testing.
• ASTM A370: Mechanical testing of steel products.
• ASTM D3039: Tensile properties of polymer matrix composite materials.
• BS 4449: Steel for the reinforcement of concrete.
4. How does the computer-controlled interface improve testing accuracy?
The integrated software allows for precise control over loading rates and strain intervals. It features real-time data acquisition, automated curve analysis (stress-strain, load-extension), and digital calibration. This eliminates manual calculation errors and ensures highly repeatable results for QA/QC protocols.
5. What safety features are included in the Servo-Hydraulic UTM?
Operator safety is a priority. These units include:
• Overload Protection: Automatic shut-off if the load exceeds the cell capacity.
• Limit Switches: Prevents the piston from exceeding its travel range.
• Emergency Stop: Instant power-off for the hydraulic pump.
• Safety Enclosures: Optional polycarbonate shields to protect against specimen fragmentation.
6. Can these machines be customized for specific grips and fixtures?
Yes. While standard hydraulic wedge grips are common, the machines can be fitted with specialized fixtures for bolt testing, compression platens for concrete cubes, or 3-point bend jigs for structural beams.
7. What maintenance is required for a hydraulic testing machine?
To ensure longevity and accuracy, regular maintenance should include monitoring hydraulic oil levels and filtration, checking for seal integrity, and annual calibration traceable to national standards.
