Pipework - Corrugated flexible metallic hose assemblies for the protection of electrical cables in explosive atmosphere (ISO 10807:1994)

Specifies the design characteristics of corrugated flexible metallic hose which can be used to protect electrical wire and cable in explosive atmospheres or atmospheres where there is a risk of fire. These hoses can be used as static protection or for the protection of cables moved infrequently, occasionally, or less than once week. Also provides instructions for the use of these hoses and the tests required for type approval.

Rohrleitungen - Flexible gewellte metallische Schlauchleitungen für den Schutz elektrischer Leitungen in explosionsgefährdeter Atmosphäre (ISO 10807:1994)

Diese internationale Norm gilt für flexible gewellte Metallschläuche, die als Schutz für elektrische Leitungen in explosionsgefährdeten oder feuergefährlichen Atmosphären eingesetzt werden können. Diese Schläuche können als statischer Schutz verwendet werden oder als Schutz für gelegentlich oder weniger als einmal wöchentlich bewegte Leitungen. Diese Internationale Norm gibt Anleitungen für den Gebrauch dieser Schläuche (siehe Anhang A) und die für eine Typ-Zulassung erforderlichen Prüfungen (siehe Anhang B).

Tuyauteries - Tuyauteries métalliques flexibles onduleuses destinées a la protection de câbles électriques dans les atmospheres explosives (ISO 10807:1994)

La présente Norme internationale prescrit les caractéristiques de conception des tuyauteries métalliques flexibles onduleuses pouvant être utilisées comme protection des fils et des câbles électriques dans les atmosphères explosives ou avec risque d'incendie. Ces tuyauteries peuvent être employées comme protection statique ou comme protection des câbles en mouvements peu fréquents, occasionnellement, moins d'une fois par semaine. La présente Norme internationale fournit également des instructions utiles pour l'utilisation de ces tuyauteries (voir annexe A) et prescrit les essais requis pour leur homologation (voir annexe B).

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.
