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 1823-2 was prepared by Technical Committee
ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses
(rubber and plastics).
Together with part 1, 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 2:
Ship/dockside discharge - Specification
1 Scope
This part of IS0 1823 specifies requirements for cargo hose
suitable for vessel-to-vessel transfer and dockside loading
and unloading of 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.

4 Dimensions
4.1 Bore
The bore shall be one of the following:
50 mm; 75 mm; 80 mm; 100 mm; 125 mm; 150 mm; 155 mm;
200 mm; 205 mm; 250 mm; 255 mm; 305 mm.
The tolerances on bore diameter shall be in accordance with
IS0 1307.
For the purposes of this International Standard, the bore is
numerically the same as the nominal bore (undimensioned)
referred to in table 3, 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 Physical properties
5.1 Non-destructive tests
5.1 1 Hydrostatic requirements
Carry out hydrostatic tests essentially in accordance with
IS0 1402, as follows.
Lay out the hose as straight as possible.
Fill with water or another suitable liquid (see note 1),
venting to remove all air, and apply a pressure of 0,07 MPa.
NOTE 1 The test medium may be water, kerosene or any other generally
approved low-viscosity fluid.
Measure the overall length of the hose (L,).
