Fire-fighting hoses - Rubber and plastics suction hoses and hose assemblies (ISO 14557:2021)
This document establishes the requirements and test methods for rubber and plastics suction hoses for fire-fighting purposes. These hoses can also be used manually to supply unpressurized water to the pump or for water discharge.
NOTE All pressures are expressed in megapascals and in bar (1 MPa = 10 bar).
Additional requirements are specified for hose assemblies, that is, hoses with couplings already fitted, where this is carried out by the hose manufacturer (see Clause 8).
Type A (rubber) hoses are intended for use at a minimum temperature of −20 °C and Type B (thermoplastics) hoses are intended for use at a minimum temperature of −10 °C.
Feuerlöschschläuche - Saugschläuche aus Gummi und Kunststoff (ISO 14557:2021)
Dieses Dokument legt Anforderungen an und Prüfverfahren für Saugschläuche aus Gummi und Kunststoff für die Brandbekämpfung fest. Diese Schläuche können auch für die manuelle Zuführung von drucklosem Wasser zur Pumpe oder zur Wasserabgabe verwendet werden.
ANMERKUNG Sämtliche Drücke werden in Megapascal und in bar angegeben (1 MPa = 10 bar).
Zusätzliche Anforderungen werden für Schlauchleitungen, d. h. Schläuche mit bereits montierten Kupplungen, für den Fall festgelegt, dass der Einband durch den Schlauchhersteller erfolgte (siehe Abschnitt 8).
Schläuche des Typs A (Gummi) sind für den Einsatz bis zu einer niedrigsten Temperatur von −20 °C und Schläuche des Typs B (Thermoplaste) für den Einsatz bis zu einer niedrigsten Temperatur von −10 °C vorgesehen.
Tuyaux de lutte contre l'incendie - Tuyaux d'aspiration et flexibles en caoutchouc et en plastique (ISO 14557:2021)
Le présent document établit les exigences et les méthodes d’essai applicables aux tuyaux d’aspiration en caoutchouc et en plastique destinés à la lutte contre l’incendie. Ces tuyaux peuvent également être utilisés manuellement pour fournir de l'eau non pressurisée à la pompe ou pour le refoulement l'eau.
NOTE Toutes les indications de pression sont exprimées en mégapascals et en bar (1 MPa = 10 bar).
Des exigences supplémentaires sont spécifiées pour les flexibles, c’est-à-dire les tuyaux avec des raccords déjà montés, lorsque le montage est effectué par le fabricant de tuyaux (voir Article 8).
Les tuyaux de type A (en caoutchouc) sont conçus pour une utilisation à une température minimale de −20 °C tandis que les tuyaux de type B (thermoplastiques) sont conçus pour une utilisation à une température minimale de −10 °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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
