Electronic Universal Tensile Testing Machine Precautions in Tensile Strength Test

Before performing the tensile strength test, a basic accuracy check must first be performed on the universal tensile testing machine. We need to prepare tensile test specimens, and the force value is preferably between 60-90% of the test range of the tensile testing machine. Clamp the sample on the Electronic Universal Tensile Tester and let the tensile tester perform a tensile test on the standard sample according to the standard speed of IOS228-2002. 9GGTextile Testing Instruments, Testing Equipment Manufacturer

When the specimen is more than 90% of the additional force of the tensile testing machine, it is necessary to stop stretching immediately, keep the specimen in a stretched state, and test then do it with the Electronic Universal Tensile Tester. Insert an extensometer or strain gauge on the sample and let the electronic universal tensile testing machine test the tensile strength of the sample according to the standard of IOS228-2002. Use Hooke's Geset to calculate the displayed amount of strain to get the tensile value of the test. Compare to the force value point on the tensile testing machine. By comparing, one can see the condition and accuracy of the electronic universal tensile testing machine.
The electronic universal tensile testing machine will have problems such as wear during long-term use, so as the tensile testing machine's working time increases, the wear and damage will become more serious. These losses lead to a reduction in the accuracy of the instrument. Some spare parts will accelerate the wear and tear of the Electronic Universal Tensile Testing Machine due to the harsh working conditions of the equipment. If it can be properly protected during work, the function and accuracy of the tensile testing machine will be maintained. So how important is it to protect the Electronic Universal Tensile Testing Machine on a daily basis. 9GGTextile Testing Instruments, Testing Equipment Manufacturer


Here the editor of Wuhan Guoliang InstruHere are some points to pay attention to in the tensile strength test of Electronic Universal Tensile Tester:
1. It is not allowed to bend the steel bar with objects that do not match the diameter. In particular, bend large diameter rebar with something small diameter. 9GGTextile Testing Instruments, Testing Equipment Manufacturer

2. After each use of the tensile testing machine, the piston does not need to quickly fall to the bottom of the oil cylinder, and a small clearance can be left for the next work.
3. If the electronic universal tensile testing machine is not to be used for a longer period of time, it should be oiled with anti-rust oil on the outside and set up in a dry environment.
4. Keep the electronic universal tensile testing machine regularly cleaned. 9GGTextile Testing Instruments, Testing Equipment Manufacturer

5. Professionals who do not understand the structure of the tensile testing machine cannot be allowed to stop and disassemble the equipment.
6. The valve on the dynamometer should not be opened, um to prevent impurities such as dust from falling inside and affecting the delicate function of the fabric.
7. When disassembling and assembling electrical appliances, it is necessary to cut off the power supply before proceeding, otherwise the electronic components are easy to be damaged.
