DIN EN ISO 10380:2013-02 EN ISO 10380:2012 (E) 4 Introduction It was decided to produce an International Standard under the Vienna Agreement on technical cooperation bet
28、ween ISO and the European Committee for Standardization (CEN) in order to maintain a unique EN ISO document. The major changes in this revision of this International Standard are the following: update of the structure of the International Standard; update of the test and performance requirements to
29、reflect the practice of the industry at the time of publication; introduction of an evaluation of conformity and a system of certification. This International Standard is a base standard for corrugated metal hoses and hose assemblies for general purpose. Corrugated metal hoses and metal hose assembl
30、ies conforming to all aspects of this International Standard are considered to be designed and manufactured to sound engineering practice. The requirements of this International Standard are of importance to designers, manufacturers, users, suppliers and importers of corrugated metal hoses. Non-perm
31、anent, detachable connections between hoses and fittings are available in the market. Their design is not covered by this International Standard. DIN EN ISO 10380:2013-02 EN ISO 10380:2012 (E) 5 1 Scope This International Standard specifies the minimum requirements for the design, manufacture, testi
32、ng and installation of corrugated metal hose and metal hose assemblies. 2 Normative references The following referenced documents are indispensable for the application of this document.
