12、). 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. International organizations, governmental and no

13、n-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.The procedures used to develop this document and those intended for its further maintenance are descri

14、bed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to

15、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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the IS

16、O list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as

17、well as information about ISOs adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.The committee responsible for this document is ISO/TC 108, Mechanical vibration, shock and condition monitoring, Sub

18、committee SC 2, Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures.This first edition of ISO 20283-5 cancels and replaces ISO 6954:2000, which has been technically revised with the following changes: crew and passenger spaces were clearly def

19、ined; measurement conditions also include dynamic positioning (DP) mode; guideline values were changed from pairs of lower and upper values representing the range of commonly accepted vibration magnitude to just one maximum value. This gives a clearer indication when this document is referred to in

20、commercial contracts or similar. The actual guideline values are somewhat severer accounting for the technical progress made.A list of parts in the ISO 20283 series can be found on the ISO website.iv ISO 2016 All rights reservedBS ISO 20283-5:2016ISO 20283-5:2016(E)IntroductionShipboard vibration th

To quantify this vibration, this document gives guidelines for the measurement, evaluation and reporting of habitability for all persons on board, especially for the crew.Vib

23、rement of vibration on ships Part 5: Guidelines for measurement, evaluation and reporting of vibration with regard to habitability on passenger and merchant ships1 ScopeThis document gives guidelines for the measurement, evaluation and reporting of vibration with regard to habitability for all perso

24、ns on-board passenger and merchant ships, especially for crew. Overall frequency-weighted r.m.s. vibration values in the frequency range 1 Hz to 80 Hz are given as guideline values for different areas on ships.This document is applicable to passenger and merchant ships with intended voyages of 24 h

25、or more.This document specifies requirements for the instrumentation and the procedure of measurement in normally occupied spaces. It also contains analysis specifications and guidelines for the evaluation of ship vibration with respect to habitability.The evaluation of low-frequency ship motion whi

26、ch can result in motion sickness is covered by ISO 2631-1.

38、cording equipment, e.g. instruments of digital, spectral or time-based type. The measuring instrumentation shall meet the requirements of ISO 8041.It is acceptable to use instruments manufactured in accordance with ISO 8041 that have frequency indications above 80 Hz provided that the filter charact

39、eristics comply with ISO 2631-2 (for frequency weighting, Wm, see Annex A).The compliance of the instrumentation system with the specifications of ISO 8041 requires a calibration at least every 2 years. The date of the last calibration shall be reported.If further data analysis is required following

40、 the measurement analysis as described in this document, the measurement data should be recorded with an electronic system which produces permanent records.4.2 Functional testEach channel of the instrumentation shall be checked by mechanical excitation of the transducer prior to and after each measu

41、rement series to ensure proper functioning.5 Measurement locations and directions5.1 Measurement locationsThe classification to be applied to the various areas of a ship according to their type, the measurement locations or any deviations from the recommendations stated in this subclause should be m

42、utually agreed between the interested parties (e.g. shipbuilder and shipowner) prior to the measurements.NOTE These details constitute a measurement plan.For practical reasons, it is advised to select the locations such that a sufficient amount of sample data are collected during the measurement pha

43、se. For large spaces, it can be necessary to distribute a number of measuring positions. Navigation bridges, engine control rooms, mess rooms and lounges, which are generally larger spaces, shall be measured on a reasonable number of positions.Measurement locations shall be selected on all decks of

44、occupied spaces in sufficient quantity in order to characterize satisfactorily the vibration behaviour of the ship with respect to habitability. The measurement locations shall be selected in accordance with the following criteria:a) For each type of occupied space as listed in Table 1, measurements

45、 are to be taken preferably in ship sections and areas where vibration is expected. From a walk-through of the ship or during the measurement campaign, locations with apparently elevated vibration should be added to the measurement locations.b) At least one space of each type of occupied space as li

46、sted in Table 1 shall be measured.c) Where multiple instances of the same type of occupied space exist on a deck, a representative sample of rooms as recommended in Table 1 should be measured.

47、Type of occupied spaceRecommended sample ratio applicable to each deck where several occupied spaces of the same type existCrew spacesCrew accommodation and offices 30 % of the spacesWork spaces 20 % of the spacesOpen-deck crew recreation spaces at least 1 samplePassenger spacesCabins and public spa

48、ces 10 % of the spacesOpen-deck recreation spaces at least 1 sample5.2 Measurement position and orientationVibration transducers shall be preferably located at positions where work is carried out. In work spaces, on the bridge, etc. measurement transducers are to be especially placed at typical duty

49、 stations of the crew. In passenger spaces, transducer shall be positioned in the centre of cabins or where passengers stay for prolonged periods of time.Vibration transducers shall be located and attached properly to the floor surface such that the vibration at the interface between the person and the source of vibration is adequately captured. In general, measurements shall be made at least 1 m from a wall. If the floor is covered with a non-rigid or resilient material the transducer shall be suitably mounted
