30、tandardization) is a worldwide federation 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 ri
31、ght to be represented on that committee. International 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. Internationa
32、l Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as
33、an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

34、ndment 1 to ISO 2631-1:1997 was prepared by Technical Committee ISO/TC 108, Mechanical vibration, shock and condition monitoring, Subcommittee SC 4, Human exposure to mechanical vibration and shock.

35、uation of human exposure to whole-body vibration: Part 1: General requirements Part 2: Vibration in buildings (1 Hz to 80 Hz) Part 4: Guidelines for the evaluation of the effects of vibration and rotational motion on passenger and crew comfort in fixed-guideway transport systems Part 5: Method for e

43、NOTE 2 Experience has shown that the crest factor can increase with measurement duration for stationary signals, as the probability of measuring a larger peak is greater. Page 6, 6.3 Add the following sentence to the end of the paragraph: In addition, when the vibration contains multiple shocks and

47、everity of vibration. The ratios are designed to indicate the degree of impulsiveness in the measured vibration signal.
