IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
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. IS0
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 IS0 9876 was prepared by Technical Committee
ISOmC 8, Ships and marine technology, Subcommittee SC 6, Navigation.
This second edition cancels and replaces the first edition (IS0 9876:1987),
which has been technically revised.

INTERNATIONAL STANDARD @ IS0
Marine facsimile receivers
Ships and marine technology -
for meteorological charts
1 Scope
This International Standard specifies the construction, performance, type testing and inspection for a shipborne
marine facsimile receiver that receives meteorological charts transmitted by “Facsimile transmission of
meteorological chart over radio circuits” stated in accordance with Recommendation 343-l of the International Radio
Consultative Committee (CCIR) and Document No. 386, Part 111-7, specified by the World Meteorological
Organization (WMO).
This International Standard applies to shipborne radio facsimile receivers for the reception of meteorological charts
and other graphical representation of meteorological conditions intended as an aid to navigation at sea.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards indicated below. Members of IEC and IS0 maintain
registers of currently valid International Standards.
ISO/R 694:1968, Positioning of magnetic compasses in ships.
IEC 9451994, Marine navigational equipment - General requirements - Methods of testing and required test
results.

International Radio Consultative Committee,

3 Definitions
For the purposes of this International Standard, the following definitions apply.
3.1 dead sector: Part of scanning line unavailable for picture signal transmissions the criteria of which are within
4,5 % + 0,5 % of the length.
3.2 facsimile: Process, or the result of the process, by which fixed graphic charts are scanned and the information
is converted to electric signals which are used remotely to produce a copy of the chart in record form.

IS0 9876: 1997(E)
3.3 index of cooperation (IOC): The value of the index of cooperation, M, is defined as follows:
M = LFlp
where
L is the length of the scanning line, in centimetres;
F is the density of the scanning line, in reciprocal centimetres.
3.4 IOC selection signal: Signal for automatic IOC selection in the facsimile receiver which is accomplished by
transmission of alternating black and white signals lasting for 5 s to 10 s with the following frequencies:
300 Hz for IOC 576
675 Hz for IOC 288 (or IOC 576 with alternate line scanning)
NOTES
1 This signal is also used for automatic starting of the receiver.
2 The envelopes of the signal are approximately rectangular.
3.5 meteorological chart: Chart portraying the state of the weather, such as weather conditions, wind force and
direction, high or low atmospheric pressure, weather front and isobar, at a particular time over a wide area.
phasing: Adjusting the phase of the independent synchronous power source so as to be able to receive the
3.6
weather chart in its correct position.
phasing signal: Signal for automatically phasing the facsimile receiver is accomplished by a 30 s transmission
3.7
of alternating, black and white signals with the following frequencies:
1 Hz for 60 lines per minute (60 r/min)
I,5 Hz for 90 lines per minute (90 r/min)
2 Hz for 120 lines per minutes (120 r/min)
NOTES
1 This signal may be also used for automatic starting, automatic selection of scanning frequency and automatic adjustment of
recording levels.
2 The wave form of this signal is either symmetrical, i.e. black and white, each lasting half the scanning line, or symmetrical
with the white lasting for 5 % and black for 95 % of the scanning line.
3.8 remote control signal: Control signal for operating the apparatus from a distance.
NOTE - The remote control signals for operating the facsimile receiver for meteorological charts include the phasing signal,
the IOC selection signal and stop signal.
3.9 SND/N: Value of signal plus noise plus distortion to noise ratio.
SND/ND: Value of signal plus noise plus distortion to noise plus distortion ratio.
3.10
3.11 spurious responses: Ratio of the input level of an unwanted signal, at the frequency of the spurious
response to the input level of a wanted signal, when the wanted and unwanted signals individually produce the
same SND/N or SND/ND ratio at the receiver output.
3.12 stop signal: Transmission of 5 s of alternating black and white signals at 450 Hz, followed by 10 s of signal
corresponding to continuous black.
NOTE - The envelopes of the 450 Hz signals are approximately rectangular.
