Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards
6、 which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to inclu

The work of preparing International Standards is normally carried out through ISO technical committees. Each m
21、ember 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 non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
22、Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casti

International Standard ISO4157-2 was prepared by Technical Committee ISO/TC10, Technical drawings, product definition and related documentation, Subcommittee SC8, Construction documentation. This second edition cancels and replaces the first edition (ISO4157-2:1982), which has been techni
24、cally revised. ISO 4157 consists of the following parts, under the general title Construction drawings Designation systems: Part 1: Buildings and parts of buildings; Part 2: Room names and numbers; Part 3: Room identifiers.iv blankENISO4157-2:1998 BSI 03-2000 1 1 Scope This part of ISO4157 specifies
25、 requirements for designation systems for rooms, areas, spaces, and voids in buildings by room names and numbers. It is intended for identification of rooms in the daily use of the buildings. For identification of rooms in a project throughout its life-cycle, i.e.conception, programming, planning, e
26、rection, maintenance, remodelling and demolition phases, seeISO4157-3. 2 Normative reference The following standard contains provisions, which through reference in this text, constitute provisions of this part of ISO4157. At the time of publication, the edition indicated was valid. All standards are
27、 subject to revision, and parties to agreements based on this part of ISO4157 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IECandISO maintain registers of currently valid International Standards. ISO 4157-1:1998, Constr
28、uction drawings Designation systems Part 1: Buildings and parts of buildings. 3 Definitions For the purposes of this part of ISO4157, the definitions given in ISO4157-1 apply. 4 Room number principle 4.1 Logical order Room numbers shall be assigned to all rooms on each floor in a logical order, pref
29、erably consecutive, starting with number n01 (where n indicates floor number) within the limits of all the parts of the building. Such limits need not be physical walls, so that outdoor or covered areas which are appropriate to include in the numbering system may be assigned room numbers, e.g.an enc
30、losed garden, a pool area, a carport, a covered loggia and in-between spaces. 4.2 Separate buildings If several buildings are included in one building project, room numbers shall be allocated independently to each building in accordance with4.1. Separate buildings may be adjacent to each other, and
31、may be interconnected by doors or openings. 4.3 Indication on drawings 4.3.1 General The room numbers and the assigned room names of the rooms shall be indicated within each room on the appropriate drawings (seeFigure 1). For clarity, room numbers and room names shall be underlined on drawings. In t
32、he physical building, the identical designation (e.g.as shown inFigure 1) shall be posted clearly at the door or by the opening to the respective room, however not underlined. This does not apply in reverse, e.g.from an office back to the corridor. Figure 1 Example of room names and numbers in the t
33、hird storeyENISO4157-2:1998 2 BSI 03-2000 4.3.2 Small rooms In small rooms, it is sufficient to indicate only the room numbers on drawings, as shown inFigure 2. However, the room names of such small rooms shall be indicated in tabular form on the same drawing sheet, unless a symbol meaning toilet, s
34、ink, clothes rack, etc., clearly advises its use. 4.4 Numbering rules 4.4.1 Room number A room number should preferably be given as a two-digit number preceded by the floor number of the building. The two-digit numbers are consecutive numbers, allocated to each room in the storey in question. EXAMPL
35、E Two-, four-, or five-digit room numbers shall only be used in extremely small or large buildings where zeroes (0) are decidedly not superfluous or necessary. When two- or four-digit room numbers are chosen, all room numbers in a building shall have the same number of digits, except for the floors
36、that have a floor number greater than9. EXAMPLE 4.4.2 “ROOM 0” principle No room shall be numbered zero on any floor, i.e.room numbers such as20,300,4000 shall not be used for rooms. Such room numbers are reserved for the eventual need to number the exterior of a building. “ROOM0” shall be the engul
37、fing exterior on all sides. EXAMPLE 1 “ROOM 300” means the exterior of the third floor. EXAMPLE 2 A wall between300 and317 is an exterior wall between room317 and the outside, just as a wall between317 and319 is an interior wall between rooms317 and319. 4.4.3 Alphanumeric rule Four-digit room number
38、s shall not be interspaced or interpunctuated. Rooms on the ground floor, mezzanine, in basement, under grade level, etc., may be assigned room numbers such as G01,M02,B03 orU04 to comply with the floor designation. EXAMPLES Floor G: Room numbers G01G99 Floor B: Room numbers B01B99 Figure 2 Example

Floor 17: Room numbers 17011799 etc. Floor 1: Room numbers 1119 or 10011999 Floor 2: Room numbers 2129 or 20012999 Floor 3: Room numbers 3139 or 30013999 . Floor 17: Room number

It should be done clockwise in the order that the rooms are reached from the main entrance or
41、in an alternative logical order. In buildings such as hotels, or in countries where such numbering is conventional, rooms should be numbered in an ascending order on both sides of a corridor in a zig-zag manner. 4.5.2 Omission of room numbers Room numbers may be omitted from a complete succession if
42、 judicious logic permits, e.g.rooms in three wings from one elevator may be numbered401426,431452, and 461474, omitting several room numbers for the sake of clarity or a future reserve. 4.5.3 Vertical shafts It is advisable, if possible, that staircases, elevator shafts, etc., be allocated the same
43、room numbers on all floors: EXAMPLE 4.6 Small rooms and spaces Small rooms, such as toilets, shall be provided with room numbers. Spaces, such as cupboards, may be allocated the number of the room in which they are situated followed by a lower-case letter as the appropriate suffix (seeFigure 3). 4.7
44、 Additional rooms If a new room is added so late in the design process that the room numbering is already allocated, this additional room shall be given the next available unused room number for that floor, without regard to a logical geometrical order and numbering sequence. This is done to avoid c
45、onfusion, and may be revised at the next thorough reallocation of room numbers throughout the building. 4.8 Fusion of rooms There may be logical gaps in a room-numbering sequence. When rooms are combined into one room, the resulting room shall keep the lower number. EXAMPLE Rooms127,128 and134 are c
46、ombined into room127. The resulting absence of128 and134 constitutes a logical gap. 4.9 Combination of rooms If three or more rooms are rebuilt into two or more rooms, the lowest room numbers available shall be used for the resulting rooms. However when existing doors and door signs are left untouch
47、ed, the existing room numbers shall be kept. 4.10 Basements and attics Spaces in basements and attics shall be given room numbers starting with their appropriate floor number in accordance with ISO4157-1. Floor 1: 112 STAIRCASE, or 113 ELEVATOR Floor 2: 212 STAIRCASE, or 213 ELEVATOR Floor 3: 312 ST
48、AIRCASE, or 313 ELEVATOR .
