European foreword
This document (prEN 14585-1:2022) has been prepared by Technical Committee CEN/TC 342 “Metal
hose, hose assemblies, bellows and expansion joints”, the secretariat of which is held by SNV.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14585-1:2006, CEN/TR 14585-2:2006, CEN/TR 14585-3:2017.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive 2014/68/EU [1].
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
This standard has been produced to address the specific needs of corrugated metal hose assemblies for
pressure applications. For applications outside the scope of EU Directive 2014/68/EU, refer to
EN ISO 10380:2012.

Introduction
Corrugated metal hose assemblies are used as components in piping.
The requirements of this standard impact designers, manufacturers, suppliers and importers of
corrugated metal hose assemblies for pressure applications.
The unique nature of a corrugated metal hose assembly is characterized by:
— the opposing requirements of pressure resistance and flexibility;
— the interactive role of its pressure bearing parts: corrugated metal hose, braid, end fittings and its
permanent joints.
As a general rule PED [1] Annex I, Clause 2.2.2 limits the experimental design method for piping to PS ·
DN less than 3000. Validation tests shall however support design of corrugated metal hose assemblies
for all practically achievable values of PS · DN.
Regarding sound engineering practice (SEP), the manufacturer is responsible for its application based on
relevant standards or other professional codes. Corrugated metal hose assemblies according to SEP are
to be designed, manufactured, verified and delivered with instructions for use in order to ensure their
safety during their intended life, when used in foreseeable or reasonably foreseeable conditions.
NOTE 1 EN ISO 10380:2012 or relevant professional codes answer sound engineering practice requirements.
NOTE 2 See also PED Guidelines I-01 [5] and I-09 [6].
For corrugated metal hose assemblies designed and manufactured according to this European Standard,
the risk analysis is already undertaken, see Annex E.
