Fire-fighting hoses - Rubber and plastics suction hoses and hose assemblies (ISO 14557:2002)
This European standard specifies the requirement and test methods for rubber and plastics suction hoses for fire-fighting purposes. Note 1: Hoses for use at lower temperatures that -10 °C (eg. -20 °C) can be supplied at the request of the purchser. Note 2: All pressures are expressed in megapascals. 1 MPa = 10 bar.
Feuerlöschschläuche - Saugschläuche aus Gummi und Kunststoff (ISO 14557:2002)
Diese Europäische Norm legt Anforderungen an und Prüfverfahren für Saugschläuche aus Gummi und Kunststoff für Feuer-löschzwecke fest.
ANMERKUNG 1 Sämtliche Drücke werden in Megapascal angegeben. 1 MPa = 10 bar.
Zusätzliche Anforderungen werden für eingebundene Schläuche, d. h. Schläuche mit bereits montierten Kupp-lungen, 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.
ANMERKUNG 2 Schläuche für die Verwendung unterhalb der oben festgelegten Temperaturen dürfen auf der Grundlage einer Vereinbarung zwischen Hersteller und Anwender geliefert werden. In diesem Fall sollte die Prüfung der Flexibilität bei Kälte (siehe 6.3) bei der vereinbarten Temperatur durchgeführt werden.
Tuyaux de lutte contre l'incendie - Tuyaux d'aspiration et flexibles en caoutchouc et en plastique (ISO 14557:2002)
La présente Norme européenne présente les exigences et méthodes d'essai applicables aux tuyaux d'aspiration en caoutchouc et en plastique destinés a la lutte contre l'incendie.
NOTE 1 Toutes les indications de pression sont exprimées en mégapascals. 1 MPa = 10 bar.
Des exigences supplémentaires sont spécifiées pour les flexibles, c'est-a-dire des tuyaux avec des raccords déja 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 a une température minimale de - 20 °C tandis que les tuyaux de type B (thermoplastiques) sont conçus pour une utilisation a une température minimale de - 10 °C.
NOTE 2 Des tuyaux utilisés a des températures plus basses que celles spécifiées ci-dessus peuvent etre prévus par un accord entre le fabricant et l'acheteur. Dans ce cas, il convient d'effectuer l'essai de souplesse a basse température (voir 6.3) a la température spécifiée.

Foreword
This document (EN ISO 14557:2002) has been prepared by Technical Committee CEN/TC 192 "Fire service
equipment", the secretariat of which is held by BSI, in collaboration with Technical Committee ISO/TC 45
"Equipment for fire protection and fire fighting".
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by June 2003, and conflicting national standards shall be withdrawn at the latest by
June 2003.
Recommendations on the frequency at which tests specified in this standard should be carried out are given in
annex F.
Users of this standard are advised to consider the desirability of independent certification of product conformity with
this standard based on testing and continuing surveillance, which may be coupled with assessment of a supplier’s
quality systems against EN ISO 9001.
The annexes A to E and Z are normative. Annex F is informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
This European Standard is mainly concerned with fire service suction hoses for fire-fighting, used manually to
supply unpressurized water to the pump.

1 Scope
This European Standard gives requirements and test methods for rubber and plastics suction hoses for fire-fighting
purposes.
NOTE 1 All pressures are expressed in megapascals. 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.
NOTE 2 Hoses for use at temperatures lower than those specified above can be supplied by agreement between the
manufacturer and purchaser. In this case, the low temperature flexibility test (see 6.3) should be carried out at the specified
temperature.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions for working pressure, proof pressure and
burst pressure given in ISO 8330 apply.
4 Classification
4.1 Type (hose construction)
Type A hoses shall consist of:
a) a rubber lining uniform in thickness, reasonably concentric and free from holes, porosity and other defects;
b) a textile reinforcement applied uniformly by any suitable method;
c) an embedded wire helix or helices evenly and uniformly applied and made from metallic material that allows
the hose to meet the specification requirements;
d) a rubber cover, ozone resistant, uniform in quality and thickness and free from defects.
Type B hoses shall consist of a flexible, thermoplastics material supported in its mass by a helix of rigid polymeric
material. The reinforcement and flexible components of the hose wall shall be fixed and free from cracks, porosity,
foreign inclusions or other defects.
4.2 Hose ends
The hose ends shall be compatible with suction hose couplings conforming to the relevant national standards.
NOTE Where soft ends or wire-free ends are used for type A hoses, they should have an additional rubb
