Plastics hoses and hose assemblies - Textile-reinforced types for hydraulic applications - Specification (ISO 3949:2009)
ISO 3949:2009 specifies requirements for three types of textile-reinforced thermoplastics hose and hose assembly of nominal size from 3,2 to 25. Each type is divided into two classes dependent on electrical conductivity requirements. They are suitable for use with water-based hydraulic fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743‑4 at temperatures ranging from 0 °C to +60 °C and oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from -40 °C to +100 °C.
ISO 3949:2009 does not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies.
Kunststoffschläuche und -schlauchleitungen - Textilverstärkte Typen für hydraulische Anwendungen - Spezifikationen (ISO 3949:2009)
Diese Internationale Norm legt Anforderungen für drei Typen von textilverstärkten thermoplastischen Schläuchen und Schlauchleitungen mit einer Nenngröße von 3,2 bis 25 fest. Abhängig von den Anforde-rungen an die elektrische Leitfähigkeit ist jeder Typ in zwei Klassen unterteilt. Sie sind für den Gebrauch mit den in ISO 6743-4 festgelegten wasserbasierten hydraulischen Flüssigkeiten HFC, HFAE, HFAS und HFB in einem Temperaturbereich von 0 °C bis +60 °C und den in ISO 6743-4 festgelegten ölbasierten hydraulischen Flüssigkeiten HH, HL, HM, HR und HV in einem Temperaturbereich von −40 °C bis +100 °C geeignet.
Diese Internationale Norm enthält keine Anforderungen an Endarmaturen. Sie beschränkt sich auf die Leistung von Schläuchen und Schlauchleitungen.
ANMERKUNG Betriebstemperaturen über 100 °C können die Lebensdauer des Schlauches wesentlich verkürzen.
Tuyaux et flexibles en plastique - Types hydrauliques avec armature textile - Spécifications (ISO 3949:2009)
ISO 3949:2009 spécifie les exigences pour trois types de tuyaux et assemblages flexibles thermoplastiques avec armature textile de dimension nominale de 3,2 à 25. Chaque type est divisé en deux classes dépendant des exigences relatives à la conductibilité électrique. Ils sont destinés à être utilisés avec des fluides hydrauliques à base d'eau, HFC, HFAE, HFAS et HFB tels que définis dans l'ISO 6743‑4 pour une plage de températures de 0 °C à +60 °C, et avec des fluides hydrauliques à base de pétrole HH, HL, HM, HR et HV tels que définis dans l'ISO 6743‑4 pour une plage de températures de −40 °C à +100 °C.
La présente Norme internationale ne contient pas d'exigences sur les extrémités de raccordement. Elle se limite aux performances des tuyaux et assemblages flexibles.
NOTE Des températures d'utilisation supérieures à 100 °C peuvent réduire matériellement la durée de vie du tuyau.
Polimerne cevi in cevni priključki - S tekstilom ojačene vrste za hidravlično uporabo - Specifikacija (ISO 3949:2009)
Standard EN ISO 3949 določa zahteve za tri vrste s tekstilom ojačenih termoplastičnih cevi in cevnih priključkov z nazivno velikostjo od 3,2 do 25. Vsaka vrsta je glede na zahteve električne prevodnosti razdeljena v dva razreda. Primerne so za uporabo s hidravličnimi tekočinami na vodni osnovi HFC, HFAE, HFAS in HFB, kot je definirano v standardu ISO 6743-4, pri temperaturah med 0 °C do +60 °C, in za uporabo s hidravličnimi tekočinami na oljni osnovi HH, HL, HM, HR in HV, kot je definirano v standardu ISO 6743-4, pri temperaturah od -40 °C do +100 °C. Zahteve za končnike v tem mednarodnem standardu niso vključene. Standard je omejen na učinkovitost cevi in cevnih priključkov.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 3949 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Hoses (rubber and plastics).
This fourth edition cancels and replaces the third edition (ISO 3949:2004), which has been technically revised.

Plastics hoses and hose assemblies — Textile-reinforced types
for hydraulic applications — Specification
1 Scope
This International Standard specifies requirements for three types of textile-reinforced thermoplastics hose
and hose assembly of nominal size from 3,2 to 25. Each type is divided into two classes dependent on
electrical conductivity requirements. They are suitable for use with water-based hydraulic fluids HFC, HFAE,
HFAS and HFB as defined in ISO 6743-4 at temperatures ranging from 0 °C to +60 °C and oil-based hydraulic
fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from −40 °C to +100 °C;
This International Standard does not include requirements for end fittings. It is limited to the performance of
hoses and hose assemblies.
