Introduction to the force value of the test machine inspection range

according toTesting machineThe test machine will stretch the standard tensile sample of the corresponding force value at the test machine according to the speed specified in GB/T228-2002. When the standard tensile sample is in a tensile state, install an extensometer or attach a strain gauge to it.Tension testerContinue to stretch the standard tensile sample, the extensometer or strain gauge displays the elongation of the standard tensile sample, convert the elongation into the tensile value, and then compare it with the same force value point as the standard tensile sample on the tensile tester dial, and determine the technical status and accuracy of the tester based on the difference in the comparison value. This method uses Hooke's law to compare the elongation amount of the standard tensile test sample into force value and the force value of the test machine dial to determine the accuracy of the test machine. This method greatly simplifies the verification operation process and brings great convenience and standardization to the daily verification of the original tensile state of the test machine.
