Increased accuracy, with servo motor resolution four times greater than previous models. Manual Non-Shift Wedge Grip. Top of This Page. Dependent on the gauge length of the specimen used, this relative accuracy requires the following absolute accuracy:. For instance, in structural materials, plastics can be pliable jiz rigid. Constant-speed strain loading with highly accurate AC servo motor and backlash-free precise ball screw. This page may contain references to products that are not available in your country.

Numeric input via control panel When using data processing software: Jls materials plastics are found in a wide variety of items used on a daily basis. Models are available with extended stroke.

More Information Accept Cookies. Testing machines are available with large effective width for models with maximum test force of 50 kN, kN or kN. Plastics come uis a wide variety of types and strengths, depending on the ingredients, mixtures, and composition used. Position control is greatly improved, allowing steady operation in low speed ranges.

To ensure tensile strength tests are performed properly, suitable grips, grip faces, and additional devices appropriate for the given material and testing efficiency must be selected.

Set as desired to 0.

Can be set as required between iis. In these applications, it is important to understand the mechanical strength properties of these plastics. New Desk-Top testing mashine with high accuracy, high performance, and simple operation.


In particular, the SIESA series enable automated extensometer arm attachment and removal, increasing testing efficiency and minimizing differences between operators. High performance with simple operatin. Acrobat Reader is a registered trademark of Adobe Systems Ltd.


They also include the previous method as Method A. Please contact us to check the availability of these products in your country. Recently, plastics have started to be used as structural materials in transportation equipment, such as automobiles and aircraft, due to their strength and light-weight nature.

Test force measurement range varies depending on the rated capacity of load cell used. Method B is preferred for plastics with a yield point.

Increased return speed The return speed can be set as desired between 0. For ISO and JIS Kthe sampling rate for data acquisition must be at least as high as the sampling frequency, which is dependent on the properties of the material and accessories.

Tensile Test Methods for Plastics: ISO 527 and JIS K 7161

Cross head speed range of 0. A model is available allowing tensile testing above the movable crosshead Optional. There are also many types of engineering plastics and plastics used in composite materials, such as carbon fiber reinforced plastics CFRP.
