Le présent document spécifie les exigences minimales pour les tuyaux et flexibles en caoutchouc à armature textile, à paroi intérieure lisse, utilisés pour l'aspiration et le refoulement de l'eau.
Trois types de tuyaux et de flexibles sont spécifiés selon leurs exigences de service, c'est-à-dire les plages de températures ambiantes et de températures de l'eau:
— températures ambiantes: −25 °C à +70 °C;
— températures de l'eau en service: 0 °C à +70 °C.
Gumene cevi in cevni priključki za dotok in odtok vode - Specifikacija (ISO 4641:2024)
Standard ISO 4641:2016 določa minimalne zahteve za s tekstilom ojačene, gladke gumene cevi in cevne priključke za dotok in odtok vode.
Tri vrste cevi in cevnih priključkov so določene v skladu z zahtevami za njihovo delovanje, tj. z njihovimi razponi temperature okolja in vode:
– temperatura okolja: od –25 °C do +70 °C;
– temperatura vode med delovanjem: od 0 °C do +70 °C.

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. Each 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 (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this d
