The tensile testing machine is a precision instrument that can be used to perform various tests, e.g. B. Tensile strength, compressive strength, compressive strength, bending deformation, elongation of materials. Various parameters such as elongation, constant elongation stress, constant stress elongation, elastic recovery of the material and the mean and standard deviation of the test data. The tensile testing machine will test the samples, and then ensure whether the quality of the products manufactured by the company meets domestic industry standards, and then can guarantee whether the company's products are qualified.
However, many companies often find that the test data is different in the process of using the tensile testing machine, but they will not correct it! Due to the long distance between tensile testing machine manufacturers, it is impossible to deal with it in time, which will affect the quality dhe affects the company's products. The following is the calibration method of the tensile testing machine compiled by the publisher of Guoliang Instrument. hoping to help companies who don't know how to calibrate the tensile testing machine to solve the current problems. !
Tensile testing machine calibration is the work that needs to be done before using the tensile testing machine to ensure the accuracy of the test results. Simply put, the calibration of the tensile testing machine is divided into the following two types:
1.Calibration of the force value of the tensile testing machine>: After the tensile testing machine enters the computer programming software, open the calibration interface, press the Test start button, take a standard weight weight and hang it slightly in the center of the jig to keep the suspension state, remember theforce value displayed by the computer and calculate the difference with the weight of the standard weight and confirm that the error does not exceed ±1%.
2. Tensile Tester Speed Correction>: (1) First note the initial position of the tensile tester beam, mark it and select the speed value on the control panel (using a standard straight steel ruler, measure the distance the beam moves). (2) When starting the tensile testing machine, use an electronic stopwatch to calculate the time from the movement to the stop of the beam, divide the moving distance of the beam by the speed of the tensile testing machine (in mm/min) from the movement to stop and check the moving distance of the beam. The difference between the test track and the standard straight steel ruler that does not exceed ±1% is the standard speed.
The above is the calibrTensile Testing Machine Testing Procedures Compiled by the Editor of National Instruments! If the tensile testing machine does not want to have any conspicuous test results, it must be calibrated!
