Tensile and Tear Strenght Test

Tensile Properties

Strip specimens are normally used for tests to ISO 527-3 and ASTM D 882. This shape is easy to produce using a cutting press or a film cutting device.
 
Dumbbell specimens are often used for quality control and require a direct measuring extensometer for strain acquisition directly on the specimen.
 
Typical test results are characteristics such as yield stress, yield strain, maximum stress and nominal strain at break.
 
When using strip specimens the results for strain at break depend on both the specimen shape and the type of specimen clamping. We recommend the use of parallel gripping specimen grips. The jaw inserts should be designed to ensure line contact between jaws and specimen. 

Typical Products for this Application:

 

Zwicki modellen är materialprovningsmaskiner i laster upp till 5 kN

Fyra lastområden erbjuds - 500 N, (112lbf), 1 kN (224 lbf), 2.5 kN (562 lbf) and 5 kN (1125 lbf) alla med tre olika slaglängder.

 

 

Temperature chambers

Temperature chambers are used in a temperature range from -80°C to +250°C.

 

 

Specimen preparation for plastics

The ZCP 020 manual cutting press employs the bent-lever principle. Attractive detail solutions allow accurate, convenient, energy-saving operation. The bent-lever length was selected to achieve up to 30 % higher cutting force in the starting range than with conventional presses. This cutting-press features particularly operator-friendly design and can be placed on any workbench or laboratory table or mounted at optimum height on a suitably sturdy wall. In addition, particular emphasis has been placed on simple, quick, and exact height adjustment of the compression die to accommodate varying heights of different cutting blades.
 

 

Grepp och testfixturer

Zwick’s wide range of specimen grips and test fixtures features a variety of designs, test-load ranges and test temperatures and covers the major application ranges of plastics, metals and component testing, at the same time delivering cutting-edge materials testing solutions.
 

 

Töjningsgivare

Extension measurement is one of Zwick’s core competences. Zwick’s product range contains extensometers with different resolution levels, measuring principles and measurement travel. A distinction is generally made between contact and non-contact measurement of extension, change in width or strain.
