Product Description

Function purpose:

Four-point bending machine suitable for metal, nonmetal and composite bending mechanical test (three point bending test and four-point bending test), and four-point bending machine meet ASTM D6109-2010 test method and standard, three point bending test machine meet GB/T1449-2005 and GB/T9341-2008 test method and standard, also can undertake such as tensile, compression, shear, tear, peel mechanics performance test. Four-point bending test function automatically detect the material most strongly value, yield strength and fracture strength and maximum deformation, yield elongation. Four-point bending machine according to GB, JIS, ASTM, DIN standard automatically calculate the bending strength, bending modulus, tensile strength, yield strength and fracture strength, maximum elongation, yield stress, elongation, elongation at break, elongation stress and elongation, elastic modulus and other parameters.

Execution standard: the four-point bending machine meet the GB, ISO, JIS, ASTM, DIN, and other test methods and standards.

Software description:

Software system: Windows/XP/Windows 7 platform software packages in both English and Chinese

Automatic storage: test conditions, test results, calculation parameters, the gauge position automatic storage.

Automatic return: after the test, four-point bending machine test beams will automatically return to the initial position.

Continuous test: a group of parameters setting is completed, four-point bending tester can test continuously.

Multiple curve: the same graphics display a variety of different curve: load - displacement, load - time, displacement, stress - strain, load - time extension and so on the many kinds of curve at two o 'clock.

Curve contrast: group superimposed on the curve of the sample can be in the same picture contrast.

The report editor: four-point bending machine can output different report forms according to the requirements of customers.

Dynamic display: testing, load, elongation, displacement and the selected test curve as the test progressed, the real-time dynamic display in the main screen.

Automatic variable scale: test load and elongation curve coordinates, if choose undeserved, four-point bending machine according to the size of the measured values, automatically transform coordinates. Four-point bending machine guarantee curve under any circumstances in the form of biggest displayed on the screen.

Peak keep: in the whole process of test, the maximum test project as you progress through the test, displayed on the screen window.
