TEST SOFTWARE DVT CKSIII DVT CKSIII
The CKS-III software program communicates with DVT DEVOTRANS tensile – compression test machines through the TCP/IP protocol to analyse the data obtained during the test in accordance with the relevant standards and to report the test results.
The CKS-III software program can be used by the customers for more specific tests such as 3-point flexural and 4-point bending, fatigue, rigidity, creep, constant load increase tests as well as for basic tests such as tensile, compression, tearing, peeling tests.
In addition to the basic tests, there are other various tests under these categories as described in the relevant standards.

Test Types
1- Tensile tests
Tensile tests are used to determine the tensile characteristics of the sample by applying to it a tensile force with a given distance or load. In addition, these tests allow one to determine the creep behaviour, maximum strength, breaking strength, breaking elongation, breaking force or, additionally, for elastic materials, yield stress and elastic modulus of the sample.
Examples of tests:
- a) Tensile properties determination test
- b) Rupture strength test
- c) Mechanical properties of fasteners for metals
- d) Tensile according to force (f), tensile according to distance (d)
- e) Test for the determination of physical features of yarns
- f) Step-by-step tensile (depending on the force f, depending on the distance d)
- g) Fixed seam opening method
- h) Ductility test
- i) Tensile creep test – Tensile according to force (f)
- j) Co-efficient friction determination test
- k) Rupture at peak test
2- Tearing/peeling tests
Tearing and peeling tests are used to determine the resistance against tearing and to measure the strength of adhesion against peeling.
Examples of tests:
- a) Tearing strength test
- b) Peeling strength test
3- Compression tests
Compression tests are used to determine the compression characteristics of the sample by applying to it a compression force with a given distance or load. In addition, these tests allow one to determine a number of parameters such as the maximum strength, the fracture resistance, the fracture distance variation, the fracture force or, additionally, for elastic materials, yield stress and elastic modulus, by applying to the sample a force in the direction of compression in a process that lasts until the point of fracture.
Examples of tests:
- a) 3 point flexural test
- b) Compression/fracture test
- c) Compression test (depending on the force f, depending on the distance d)
- d) Energy absorption determination test
- e) Step-by-step compression (depending on the force f, depending on the distance d)
- f) Creep test (waiting under a constant load test) – with the 3-point bending method (f in accordance with the force)
- g) Creep test (waiting under a constant load test) – in the direction of compression (f in accordance with the force)
4- Ring stiffness tests
Ring stiffness tests are used to determine creep, ring elasticity and ring stiffness for plastic pipes and ring deformation value for spiral-wound plastic pipes and fittings.
Examples of tests:
- a) Determination of ring stiffness
- b) Pipe creep test
- c) Ring shape change test
- d) Determination of ring flexibility
5- Hysteresis tests
Hysteresis tests consist of subjecting a material to repeated loadings. After various loading and unloading movements, the loss of energy that has occurred in the material is measured at the end of the test. It allows one to determine the loss of force resulting from repetitive tensile – compression operations within a restricted distance of movement.
Examples of tests:
- a) Effort test (depending on the distance d)
- b) Fatigue hysteresis test (depending on the force f)
- c) Fatigue hysteresis test (depending on the distance d)
- d) Hardness test (depending on the force f)
- e) Radial loading test
- f) Cycled hysteresis test
- g) Determination of the elasticity of fabrics
- h) Stepped hysteresis test (depending on the force f)
- i) Stepped hysteresis test (depending on the distance d)
6- 4-point bending,-tensile-compression tests
4-point bending-tensile-compression tests are used to measure the final load carried by the sample that migrates under the effect of slipping to calculate the slip modulus from the load – deflection curve. To explore the bending behaviour of samples, features such as resistance to bending, bending modulus and bending stress/size variation relation are determined.
Examples of tests:
- a) 4-point bending test
- b) Traction strength test
- c) Compression strength test
- d) 4-point wrinkling test
- e) Determination of the creep coefficient test
- f) 4-point bending strength determination test for glass
