Just on basis of Tan Delta test on insulation one can not certify that equipment is suitable or not for service.

Tan Delta test is a diagnostic tool to check state of insulation. Hence it is useful if base reference test report is available. That is when the test was performed on new machine or after its winding has been rewound. And by repeating the test during annual PM schedule one can compare and predict condition of insulation.
