The document describes various inspection tools and the standards they adhere to for inspecting different mechanical systems and components. It outlines tools for measuring vibration, temperature, noise, thickness, surface thinning/corrosion, cracks, currents, calibration, sprinkler systems, hydrants, and façades/ceilings. The tools are associated with international standards for evaluating things like rotodynamic pumps, electrical equipment, piping systems, valves, and fire protection systems.
