For example, for a material with a gauge length L o of 75 mm, a grip face length L of mm, a minimum extensometer resolution R of 0. In these applications, it is important to understand the mechanical strength properties of these plastics. For instance, in structural materials, plastics can be pliable or rigid.

In particular, the SIESA series enable automated extensometer arm attachment and removal, increasing testing efficiency and minimizing differences between operators. 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.

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

They also include the previous method as Method A. Dependent on the gauge length of the specimen used, this relative accuracy requires the following absolute accuracy:.


Automatic js cell span adjustment, One-push auto zero, Auto return to test start position No overshootingTest condition registration, Manual 3 level speed setting freely settableAnalog output of test force and position, and support for continuous repeated tensile and compression testing.

Method B is preferred for plastics with a yield point. More Information Accept Cookies. Included in these methods are accuracy specifications for the test frame and test accessories.

Tensile and Compression material test machine / TECHNOGRAPH TGI series – MINEBEA/Sensing Device BU

Shimadzu offers a broad line of accessories to support plastics tensile testing, such as grips ranging from manual non-shift wedge grips to pneumatic and hydraulic versions, and axial centering systems. Position control is greatly improved, allowing steady operation in low speed ranges.

High performance with simple operatin. Models are available with extended stroke. Testing machines are available with large effective width for models with maximum test force of 50 kN, kN or kN.

Cross head speed range of 0. There are also many types of engineering plastics and plastics used in composite materials, such as carbon fiber reinforced plastics CFRP.


Below this, can be set in 9 steps: 7712 come in a wide variety of types and strengths, depending on the ingredients, mixtures, and composition used. Set as desired to 0. Constant-speed strain loading with highly accurate AC servo motor and backlash-free precise ball screw. Top of This Page. Increased return speed The return speed can be set as desired between 0.


Manual Non-Shift Wedge Grip. Numeric input via control panel When using data processing software: 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. Dependent on the gauge length of the specimen used, this relative accuracy requires iis following absolute accuracy: Can be set as required between 0.

Automatically set in accordance with test conditions created. New Desk-Top testing mashine with high accuracy, high performance, and simple operation. 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.
