9、ber bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch 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, govern- m
10、ental 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 committees at-e circulated to the
11、member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 6242-3 was prepared by Technical Committee ISO/TC 59, Building construction, Sub-Committee SC 3, Functionalluser requirements and Pe

15、ing with the expression of en- vironmental requirements for buildings, in terms suitable for use in regulations and briefs for building projects. The Parameters defined tan be used for routine verification of the Performance of buildings, either by calculation (for example at the design Stage) or me
16、asurement (for example of elements, equipment, spaces or whole buildings), and are meant to provide readily understood information on users requirements throughout the building process. This set of International Standards is not intended to represent the complete state of knowledge about these aspec
17、ts of environmental sci- ence, some of which are the concern of other ISO Technical Com- mittees. . . .

19、ers tan be identified, ex- pressed and quantified. It describes users objectives and the Parameters used to express them. For each parameter-, it specifies units of measurement, preferred increments for values and means of evaluation. lt also lists the environmental and human factors affecting the c
20、hoice of a value (criterion) for each Parameter. lt is intended for use a) in preparing briefs for building projects; b) in formulating building laws and regulations; c) in drafting Standards and other normative docu- ments; and d) more generally when specifying the required Performance of buildings
21、 in terms of users re- quirements. Some of the Parameters given in this patt of ISO 6242 apply only to certain types of building. Compliance with this part of ISO 6242 does not therefore depend on implementing the whole of its contents in every case. 2 Normative references The following Standards co

The choice of some Parameters and criteria will dif- fer, depending on the type of external noise to which the building is subjected. 4 Parameters for expressing users requirements Acoustical comfort, quality and privacy depend on a) the airborne Sound
32、 insulation provided by in- terior building elements (Walls, floors, doors, etc.); b) the airborne Sound insulation provided by ex- terior building elements (external Walls, facades, I windows, etc.); c) the impact Sound insulation of floors and Walls; d) acceptable Sound pressure levels, taking int
33、o account any Sound required for masking (priv- acy); and e) the reverberation time of rooms or spaces. 3 Users objectives 3.1 Control of the acoustical environment within buildings shall fulfil the following objectives: a) to provide a suitable Standard of freedom from annoyance due to intrusive no
34、ises, whether originating within or outside the building: b) to provide a suitable Standard of Speech privacy between rooms or spaces; and c) to provide a suitable Standard of acoustic quality within rooms or spaces. 3.2 Criteria to meet these objectives shall reflect the following: a) activities to
35、 be accommodated; b) age and health of the occupants; c) proportion of likely occupants it is intended to satisfy; d) time during which the requirements must be satisfied (taking account of variations in the noise emitted by various sources); and 4.1 Location, uniformity and tolerante for acoustical
36、 Parameters As the level of Sound will be essentially uniform in all but the largest rooms or spaces, it is not necessary to state requirements linked to the lo- cations at which the requirements will apply. Uniformity may be required of the acoustic quality of auditoria, but this involves details b
37、eyond the scope of this part of ISO 6242. The various Sound indices incorporate a certain tol- erance in their treatment of Sound of differing fre- quencies. Conventional tolerante requirements apply only to reverberation time, and are stated as part of the Parameter. 42 . Expression of acoustical P
