Abstract: Equipment including vessels, ships, automobiles and railroad cars where many items of equipment are installed in the limited space, continue to be exposed to special environments such as noise, vibration and shocks, so, they must be tested for their durability, so as to install verified items of equipment to ensure the customer safety and life. However, testers should accurately implement test requirements, so, their accuracy is crucial and laboratories verify tester’s accuracy using various methods. This study verified the accuracy of the electric vibration testers designed mainly for testing vibration, using the measurement uncertainty technique.
