Experimental equipment facilities on the International Space Station (ISS) are required not to disturb the microgravity environment, and the facilities must be designed so that the generated disturbances do not violate the microgravity requirement. In order to make validation of the design, experimental or analytical verification must be performed according to the ISS program documentation. As the microgravity requirement is classified as three categories: (a) Quasi-steady Requirements (b) Vibratory Requirements (c) Transient Requirements, this study attempts several approaches for the category (b) to measure or estimate the parts level disturbance, which is required as the first step to estimate the system level disturbance. Next, system level verification is attempted based on the results of the approaches for parts level. As one of examples of experimental equipment facilities for this study, the Engineering Model (EM) of the Electrostatic Levitation Furnace (ELF) is utilized.
