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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,
as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
The committee responsible for this document is ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Rubber and plastics hoses and hose assemblies.
This fourth edition cancels and replaces the third edition (ISO 6804:2009), which has been technically
revised with the following main changes:
— Clause 2 has been updated: ISO 1746 has been deleted and replaced by ISO 10619-1;
— Clause 8 has been extended to cover hydrostatic proof pressure tests and burst testing. A new table
(Table 2) has been added to specify maximum working pressures, proof pressures and minimum
burst pressures for each type. All subclauses have been renumbered;
— 8.5 (old 8.3) and 8.6 (old 8.4) have been extended with one line specifying the specific test pressures
for the different hose types after kinking and ageing tests;
— Clause 11 a), b), c), e) and example have been amended;
— Annex A and Annex B have been amended to include hydrostatic pressure proof test and burst
testing. The term “hose assembly” has been added to the description of routine tests. Table B.1
(column production acceptance test) has been filled in to specify which tests are recommended per
batch (the previous edition specified N.A. to all the tests);
— Table C.2 has been extended to show hydrostatic proof pressure test and burst test results.

This document specifies the requirements for three types of rubber or plastics inlet hoses and hose
assemblies for washing-machines and dishwashers connected to the domestic water supply at a
pressure not exceeding 1 MPa (10 bar).
It is applicable to the following types of hose:
— type 1: rubber hoses for unheated water supply (maximum temperature 70 °C);
— type 2: rubber hoses for heated water supply (maximum temperature 90 °C);
— type 3: plastics hoses for unheated water supply (maximum temperature 60 °C).
There may be national requirements for hose fittings and hoses conveying drinking water which must
be complied with.

4 Classification
Hoses are designated as one of the following three types, depending on the hose material and the
temperature of the water supply.
Type 1: Rubber hoses for a medium-temperature water supply (up to 70 °C) — for a maximum
working pressure of 1 MPa (10 bar).
Type 2: Rubber hoses for a high-temperature water supply (up to 90 °C) — for a maximum working
pressure of 1 MPa (10 bar).
Type 3: Plastics hoses for low temperature (up to 60 °C) water supply — for a maximum working
pressure of 0,8 MPa (8 bar).
5 Couplings and fittings
Hoses may be fitted with the appropriate type of coupling and end fitting to form hose assemblies.
NOTE Guidance on coupling types is given in ISO/TR 17784.
6 Materials and construction
The hose construction shall be as follows.
a) The hose lining shall consist of rubber for type 1 and type 2 or thermoplastics material for type 3.
b) The hose reinforcement shall consist of natural or synthetic textile material applied by any suitable
technique.
c) The hose cover shall consist of an ozone-resistant rubber for type 1 and type 2 or a weather-
resistant thermoplastics material for type 3 (or, alternatively, a stainless-steel braid may be used
instead of a cover).
The lining and the cover shall be of uniform thickness, concentric, fully gelled and free from visible
cracks, porosity, foreign inclusions and other defects which could cause the hose to be unserviceable.
7 Dimensions and tolerances
7.1 Inside diameters, tolerances and minimum wall thickness
7.1.1 Type 1 and type 2 hoses
The preferred values for the bore of the hose are 10 mm and 12,5 mm.
The tolerances on the bore will depend on the characteristics of the end fittings; consequently, they
shall be agreed between the manu
