In this paper, we investigate the problems for safety evaluation of electromechanical equipments metal structures based on the virtual instrument testing technology with interval grey linguistic variables. We utilize the interval grey linguistic weighted geometric (IGLWG) operator to aggregate the interval grey linguistic variables corresponding to each alternative and get the overall value of the alternatives, then rank the alternatives and select the most desirable one (s). Finally, an illustrative example for safety evaluation of electromechanical equipments metal structures based on the virtual instrument testing technology is given
