Foreword
ISO (the International Organization for Standardization) 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 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 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 least 75 % of the member bodies casting a vote.
International Standard ISO 4157-1 was prepared by Technical Committee ISO/TC 10, Technical drawings, product
definition and related documentation, Subcommittee SC 8, Construction documentation.
This second edition cancels and replaces the first edition (ISO 4157-1:1980), which has been technically 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

3 Definitions
For the purposes of this part of ISO 4157, the following definitions apply.
3.1
room
area or volume, space or void bounded actually or theoretically, even though it is not traditionally thought of as a
room
EXAMPLES
Balcony in a movie theatre

 Staircase (considered to be a separate room in each floor)
 Auditorium with folding doors
 Partly covered terrace

room to be allocated a room number, it should have some of these physical limitations.

3.2
room name
common or given name which represents the intended use or function of the room
NOTES

e.g. CLASSROOM A, CLASSROOM B, etc.
2  Additions to room names such as B and 3, as in CLASSROOM B, BEDROOM 3, should only be assigned to room names if
they are so called in the practical use of the building. Given names like CHOPIN or TAYLOR should in such instances be
preferred, e.g. CHOPIN AUDITORIUM, TAYLOR SUITE, etc., for their mnemonic value.
3.3
room number
number allocated to a room
NOTES
1  See 3.1.
2  Room number in the traditional sense is reserved for the practical use of a building, i.e. the interface between building and
human beings. Room numbers may be revised by thorough reallocation when important changes are made, such as
remodelling, extensions, or new ownership. The time for the changeover an
