16、of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. I
17、nternational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical
18、 committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

This part of ISO 10816 provides specific guidanc
24、e for assessing the severity of vibration measured on bearings, bearing pedestals, or housings of industrial machines when measurements are made in situ. Two criteria are provided for assessing the machine vibration. One criterion considers the magnitude of the observed vibration; the second conside
