Reinforcement Steel Bar Testing

The CXWAW – G Series Computer Controlled Electro-hydraulic Servo Universal Testing Machine adopting a four columns frame structure with oil cylinders placed downwards, equipped with high-strength organic glass protective doors, with good rigidity, safe & stable. The jaw hydraulic clamping system provides real-time oil supply. Adopting servo motor control, silent & energy-saving with low system heat generation. Adopting a high rigidity semi-closed structure with a embedded design. Also adopting a duo oil circuit design increases work efficiency. The testing machine is equipped with a spring shock absorbing system to reduce vibration. When tensile testing, the oil cylinder move downward and the reflection force decreases; when the specimen is pulled apart, the impact force is small & the noise is reduced. No need to lay a foundation & fast installation.

Tensile testing is a destructive test process that provides information about the tensile strength, yield strength and ductility of a material. Laboratory WATIMA TESTING Sdn. Bhd. (WATIMA) performs the tensile test in accordance with industry specifications (listed below). The tensile test or tension test involves applying an ever-increasing load to a test sample up to the point of failure. The process creates a stress/strain curve showing how the material reacts throughout the tensile test. The data generated during tensile testing is used to determine mechanical properties of materials and provides the following quantitative measurements:
- Tensile strength, also known as Ultimate Tensile Strength (UTS), is the maximum tensile stress carried by the specimen, defined as the maximum load divided by the original cross-sectional area of the test sample.
- Yield strength is the stress at which time permanent (plastic) deformation or yielding is observed to begin.
- Elongation measurements are typically elongation, defined as the strain at, or after, the point of fracture, and reduction of area after the fracture of the test sample.

Bend tests deform the test material at the midpoint causing a concave surface or a bend to form without the occurrence of fracture and are typically performed to determine the ductility or resistance to fracture of that material. Unlike in a flexure test the goal is not to load the material until failure but rather to deform the sample into a specific shape. The test sample is loaded in a way that creates a concave surface at the midpoint with a specified radius of curvature according to the standard in relation to which the test is performed. These characteristics can be used to determine whether a material will fail under pressure and are especially important in any construction process involving ductile materials loaded with bending forces. If a material begins to fracture or completely fractures during a three or four point bend test it is valid to assume that the material will fail under a similar in any application, which may lead to catastrophic failure.

CXGWE-E Series Computer Display Steel Strand Testing Machine adopting a six-column, double-space frame structure, it has the characteristics of high stiffness & good stability. The use of automatic hydraulic clamping fixtures ensures reliable & convenient clamping. The middle beam is equipped with a clearance plate device, which can effectively eliminate the transmission gap between the bar & the nut., making the cross-section more flat when the specimen is pulled apart. Specially designed clamp structure to increase the maximum clamping area of steel strand. Disk storage with test results, printing of test results & test curve, report processing of bacth test results, database management & network interface reserved. Adopting microcomputer automatic data acquisition, processing and synchronous screen display of test data & test curve. The testing software support synchronous control of the testing machine’s compression & bending resistance which can greatly improve equipment efficiency.
