ISO 10807:1994(E) 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. Esch 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 (1 EC) 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 ISO 10807 was prepared by Technical Committee lSO/TC 5, Ferrous metal pipes and metalic fittings, Subcommittee SC 11, Flexible interlocked and convoluted metallic hoses. Annexes A and B form an integral part of this International Standard. An- nex C is for information only. 0 ISO 1994 All rights reserved.

INTERNATIONAL STANDARD 0 ISO ISO 10807:1994(E) Pipework - Corrugated flexible metallic hose assemblies for the protection of electrical cables in explosive atmospheres 1 Scope This International Standard specifies the design char- acteristics of corrugated flexible metallic hose which tan be used to protect electrical wire and cable in explosive atmospheres or atmospheres where there is a risk of fire. These hoses tan be used as static protection or for the protection of cables moved in- frequently, occasionally, or less than once week. This International Standard also provides instructions for the use of these hoses (see annex A) and the tests required for type approval (see annex B). 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were valid. All Standards are subject to revision, and Parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most re- cent editions of the Standards indicated below. Members of IEC and ISO maintain registers of cur- rently valid International Standards.
