Foreword
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 1823-1 was prepared by Technical Committee
ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses
(rubber and plastics).
Together with part 2, this part of IS0 1823 cancels and replaces
IS0 1823:1975 which has been technically revised.
IS0 1823 consists of the following parts, under the general title Rubber
hoses and hose assemblies:
- Part 1: On-shore oil suction and discharge - Specification
- Part 2: Ship/dockside discharge - Specification

Rubber hoses and hose assemblies -
Part 1:
On-shore oil suction and discharge - Specification
1 Scope
This part of IS0 1823 specifies requirements for cargo hose
suitable for dockside loading and unloading of vessels
transporting petroleum-based products that are liquid at
ambient temperatures and atmospheric pressure. The hoses are
suitable for use in the temperature range - 20 OC to + 80 OC.
Hose assemblies made with an inner lining of flexible metal
and hoses designed for off-shore applications are not
included.

4.1 Bore
The bore shall be one of the following:
50 mm; 75 mm; 80 mm; 100 mm; 125 mm; 150 mm; 160 mm;
200 mm; 205 mm; 250 mm; 255 mm; 315 mm; 400 mm; 500 mm.
The tolerances on bore diameters shall be in accordance with
IS0 13070

numerically the same as the nominal bore (undimensioned)
referred to in table 3, table 4, clause 6 and clause 7.
4.2 Length
The length of hose shall be specified by the purchaser and
shall be subject to the tolerances given in table 2.

5.1.1 Hydrostatic requirements
Carry out the hydrostatic tests essentially in accordance with
as follows.

Lay out the hose as straight as possible.
Fill with water or another suitable liquid (see note l),
venting to remove all air, and apply a pressure of 0,07 MPa.

Raise the pressure from 0,07 MPa above atmospheric to the
maximum working pressure specified in clause 3. Hold this
pressure for 10 min. Check that there is no evidence of
weeping or leakage and no failure.
Before releasing the test pressure, measure the overall length
of the hose (L,).
Reduce the pressure to zero.
After an interval of at least 15 min, raise the pressure again
to 0,07 MPa above atmospheric and measure the overall length
of the hose (I+
