European foreword
This document (prEN 854:2024) has been prepared by Technical Committee CEN/TC 218 “Rubber and
plastics hoses and hose assemblies”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 854:2015.
This document includes the following significant technical changes with respect to EN 854:2015:
— EN 853, 854, 856 and 857 have been aligned;
— updated normative references;
— Table 7 added;
— Annex A deleted;
— Annex C deleted.
1 Scope
This document specifies requirements for three types of textile reinforced rubber hoses and hose
assemblies of nominal bore from 5 to 100. The types are defined in Clause 4.
They are suitable for use with:
— hydraulic fluids in accordance with ISO 6743-4 with the exception of HRD R, HFD S and HFD at
temperatures ranging from −40 °C to 100 °C;
— water-based fluids at temperatures ranging from −40 °C to +70 °C;
— water at temperature ranging from 0 °C to +70 °C.
The hoses are not suitable for use with castor oil based and ester-based fluids.
The document does not include requirements for end fittings. It is limited to the performance of hoses
and hose assemblies.
NOTE Requirements for hydraulic hoses for underground mining are covered in other documents.

4 Classification
Three types of hose are specified, distinguished by their construction, maximum working pressure and
minimum bend radius
— Type 1TE: hoses with a single layer of textile reinforcement;
— Type 2TE: hoses with one or more braid(s) of textile reinforcement;
— Type 3TE: hoses with one or more braid(s) of textile reinforcement (higher maximum working
pressure).
NOTE Hose Types 1TE are used or low-pressure applications therefore they are not subjected to impulse test
and vacuum resistance test.
Hoses and hose assemblies are not be operated outside the limits of this document.
5 Materials and construction
5.1 Hoses
Hoses shall consist of an oil and water-resistant synthetic rubber lining, one or more layers of textile yarn
and an oil and weather resistant synthetic rubber cover. Two or three braided hose types shall be
separated by an insulating layer of synthetic rubber.
5.2 Hose assemblies
Hose assemblies shall only be manufactured with those hose fittings whose functionality has been
verified in accordance with subclauses 7.1, 7.3, 7.4 and 7.5 of this document.
6 Dimensions
6.1 Diameters and concentricity
The diameters of the hoses shall be measured in accordance with EN ISO 4671 and as such shall conform
to the values in Table 1.
