Software includes an external interface box that controls the movement of the load frame and acquires load, strain and deflection data
Admet offers tensile and flexural test routines that are specific to the plastics industry.
Its MTestWindows materials testing system provides test routines for ASTM D790 and ISO 178 flexural properties testing and ASTM D638 and ISO 527 tensile testing.
The plastics testing routines are included at no charge in MTestWindows.
Users can select the standard tests or develop and store customised tests for specific lab situations and test requirements.
MTestWindows is a software program that runs on personal computers with the Microsoft Windows operating system.
It includes an external interface box that controls the movement of the load frame and acquires load, strain and deflection data.
MTestWindows can be used to update existing electromechanical and hydraulic test frames.
"MTestWindows is an extremely flexible system for tensile and flexural testing of virtually any material," commented Richard Gedney, Admet founder and president.
"For plastics, we've built in the test parameters so our customers can eliminate manual test operations and automatically calculate the results.
"Operators simply select the D638 or D790 routines from a menu of available tests.
"MTestWindows controls the test, reports the results and performs all of the necessary calculations".
MTestWindows has one encoder input channel that measures crosshead position and uses up to three analogue input channels to measure load, axial and transverse strain.
It employs a high speed 32-bit microprocessor for precise closed loop control of electrohydraulic and electromechanical test frames and uses a proportional integral derivative control algorithm with software selectable control modes for smooth transfer between load, position and strain control.
MTestWindows features monotonic, cyclic and segmented control profiles and offers up to 30 calibration tables per analogue channel for multiple load cell and extensometer requirements with up to five calibration points per transducer.
MTestWindows calculates key test parameters, such as ultimate tensile strength, offset yield strength, modulus of elasticity, total elongation, percent of elongation, and many more.
Test reports include a stress-strain plot with all calculated test results.
MTestWindows can also generate reports, which include a statistical summary of test results.
All data can be exported in Ascii delimited format for easy import into common spreadsheet and database programs.
