Digital calculation pendulum impact testing machine can replace the calculation of manpower
 
Digital calculation izod impact testing machine is a new type of impact testing machine which can instantaneously measure and record the characteristic curve of the material in the impact process. 
In the display of the development of enterprises play a very important role, especially in the study of new materials , the stability of the material and practical through the test machine can get a better test data. 
By replacing the pendulum and the specimen base, two types of tests can be made for simply supported beams and cantilever beams. Especially in the reference to the computer for data analysis, the digital calculation pendulum tester test data and analytical ability to replace the human calculation, the speed and accuracy of the test have been improved, it is sent by detecting the angular displacement signal to the computer for data processing, high precision, used in electronics, plastics, hardware, bags, handbags, furniture and other industries.
 
The difference between the cantilever digital display impact testing machine and the simply supported beam impact testing machine:
1, the test standard is different: simple support beam impact testing machine it meets ISO 179, GB / T 1043, GB / T 2612, JB / T 8762, GB4742 standard. Izod impact testing machine which conforms to IS0 180, ASTM D256, GB / T 1843, GB / T 2611, JB / T 8761 and other standards.
 
2, Digital display pendulum impact testing machine the test method is different: Digital display charpy impact tester it is the sample level, both ends are not fixed. Release the pendulum to impact the specimen. If the specimen is not damaged, change the heavier pendulum and repeat the above steps until the specimen is damaged. Izod impact testing machine It is placed vertical and clamped in the impact testing machine, with a notched side facing the pendulum edge. Release the pendulum to impact the specimen. If the specimen is not damaged, then for a heavier pendulum, until the sample damage. This experiment can also be carried out at lower temperatures.
 
3, sample sampling specifications are different: Digital display charpy impact test machine sample thickness of 80 × 10mm. The the most common thickness is the size of 80mm. (0.125 inches), while the better thickness is 6.4mm, because it's not so easy to bend or brittle. The depth of the specimen gap is 10.2 mm. ISO standard sample is to cut the end tabs of 1A multi-character samples. After cutting the specifications of the sample 80 × 10 × 4mm. The depth of the specimen notch is 8 mm.
 
4, the test data is different: digital display charpy impact test machine unit if impact is joule. The impact strength is the ratio of the impact energy (J) to the cross-sectional area at the notch. The greater the test data, the greater the tough impact of the material. Digital display izod impact test machine The unit of impact energy at ASTM (American Society for Testing and Materials) is J / m or ft-lb / in. The impact strength is obtained by dividing the impact energy (in J or ft -lb) by the thickness of the specimen. The test results are usually the average of the five samples. The unit of impact energy in ISO is kJ / m2. The impact strength is the ratio of the impact energy (in terms of J) to the area under the notch. The test results are usually the average of 10 samples. The greater the value, the greater the toughness of the material.
