50kn Electronic Universal Testing Machine Determination Glass Bending Strength
Determination of the bending strength of glass - Test with specimen supported at two points (four point bending)
Product description:
The testing machine incorporate the following features:
a) The stressing of the specimen can be capable of being applied from zero up to amaximum value in a manner which minimizes shock and is stepless.
b) The stressing device is capable of the specified rate of stressing
c) The testing machine incorporate a load measuring device with a limit of error of ＜1.0 % within the measuring range
d) The supporting rollers and the bending rollers have a diameterof 50 mm and a length of not less than 365 mm. All the rollers can be free to rotate.
Equipped with the computer & Software & printer, it can display, record, process and print the test results, and control test procedures as the set program and can draw test curves automatically in real time. The PC controlling system can also realize the close-loop control of the parameters such as loading force, specimen deformation, and crosshead stroke earameters can be automatically found according to GB, JIS, ASTM, DIN, ISO and other standards.ith the ord, process and print the test results, and control test procedures as the set program and can draw test curves automatically in real time. The PC controlling system can also realize the close-loop control of the parameters such as loading force, specimen deformation, and crosshead stroke etc. They are essential testing instrument for quality testing section, university and colleges, research institution and industrial and mining enterprise.
