Make your metals applications standard-compliant with ease

testXpert III offers over 600 Standard Test Programs, enabling you to find the right test program for almost any standard - with standard compliance guaranteed and with accurate, repeatable, worldwide reproducible and traceable test results. 

  • two-sided E modulus determination to ISO 6892-1 
  • validation to ISO 6892-1/TENSTAND
  • excellent strain rate control to ISO 6892-1 A(1) and ASTM E 8 as well to EN 2002-001
  • automatic estimate ot the optimum strain rate on the basis of the foregone test to ISO 6892-1 method A(2)

For tests that go beyond the standard or that are for freely configuring the test sequence for a tensile, compression, flexure, tear growth, adhesion, peel, and cyclical tests, testXpert offers already prepared Master Test Programs.

testXpert III for metal applications

Strain rate control with the testing software testXpert III

Testing SoftwaretestXpert III and its Tensile Master Test Program ensures that all standardrequirements included in the Tensile Test to DINEN ISO 6892-1 are fulfilled. This includes:

  • Event-controlled and therefore automatic and standard-compliant test speed changes after determination of ReH, ReL or Rp and Rt.
  • Event-controlled and therefore automatic and standard-compliant switching of drive control type and therefore optimization (shortening) of test time, particularly important for robotic testing systems with high specimen throughput.
  • The adaptive controller adjusts automatically to optimum control for different specimen geometries (cross-section) and material properties (strength) and eliminates operator intervention / influence.

Further advantages of testXpert III

The simple and intuitive operation of the testing software enables additional features, such as:

  • very easy switching to other standard-compliant drive control types (position or force)
  • automatic logging of test speeds used
  • setting of test parameters
  • creating test reports
  • export of specimen characteristics­
  • export to databases
  • creation of specific ‘Test Programs’ by the user­
  • reduction to one-button operation possible
  • software algorithm validation with TENSTAND raw data and internationally agreed target results

TENSTAND Software Validation 

100% reliable test results with validation to ISO 6892-1/TENSTAND

The test results that are determined with the software to ISO 6892-1 can be verified and validated with an internationally coordinated data set and internationally coordinated test results. In a European research project with the acronym TENSTAND, raw data from tests on metals was generated and qualified. This data was used to determine and qualify test results and ranges of results. With the TENSTAND sets of data and sets of results the testing software can be quickly and reliably verified through comparison of results. The National Physical Laboratory (NPL) in London has these sets of data and sets of results available.

  • The National Physical Laboratory (NPL) is the British counterpart to the German national metrology institute Physikalisch-Technische Bundesanstalt (PTB). It defines the national standards applicable in the field of physics and technology. 
  • Its responsibilities include the determination of fundamental and natural constants, representation, preservation and transfer of legal units of the International System of Units (SI), supplemented by services such as UKAS (United Kingdom Accreditation Service) calibration services for the legally regulated sector.

Verify your test results with TENSTAND software validation.

Automated data import and export

testXpert III reduces input errors, increases efficiency in the test lab and can communicate with any IT system via automated importing and exporting.

  • All test relevant data is imported quickly and directly from ERP systems, databases, or external devices.
  • Data can be exported into your customary evaluation analysis platform.
  • Quickly edit test reports as needed—testXpert III automatically exports data after requirements have been set once.
  • With testXpert III, external sensors and measurement amplifiers are synchronized simultaneously.
