Overview
EN 853:2015 - Rubber hoses and hose assemblies - Wire braid reinforced hydraulic type (CEN) specifies performance requirements for four types of wire-braid reinforced hydraulic hoses and hose assemblies with nominal bore 5–51 mm. The standard covers materials, construction, dimensions, hydrostatic and impulse resistance, bend radius, cold flexibility, abrasion, adhesion and fluid/ozone resistance. It applies to hoses for hydraulic fluids (ISO 6743‑4, excluding HFD R/S/T), water-based fluids and water within defined temperature limits. EN 853:2015 is focused on hose performance; end fittings are not covered.
Key topics and technical requirements
- Types covered: Type 1ST (single wire braid), 2ST (two braids), 1SN (single braid, thinner cover for certain fittings), 2SN (two braids, thinner cover).
- Materials & construction: oil- and water-resistant synthetic rubber lining, one or two layers of high‑tensile steel wire, oil- and weather‑resistant rubber cover.
- Operating media & temperature:
- Hydraulic fluids per ISO 6743‑4 (except HFD R, HFD S, HFD T): −40 °C to +100 °C
- Water-based fluids: −40 °C to +70 °C
- Water: 0 °C to +70 °C
- Note: not suitable for castor- or ester-based fluids.
- Pressure & strength: Defines maximum working, proof and burst pressures (by nominal bore and hose type) tested per EN ISO 1402 (hydrostatic testing).
- Impulse testing: Dynamic impulse requirements per EN ISO 6803 - e.g., 1ST/1SN: minimum 150,000 cycles at specified impulse pressures for smaller bores; 2ST/2SN: minimum 200,000 cycles.
- Dimensional & mechanical limits: Nominal bore, concentricity, length tolerances, minimum bend radius (examples: 90 mm for bore 5 mm up to 630 mm for bore 51 mm), flatness limits when bent.
- Other tests: Cold flexibility, adhesion (EN ISO 8033), vacuum resistance (EN ISO 7233), ozone and abrasion resistance, and fluid resistance testing (ISO 1817).
Applications and practical value
- Use for industrial and mobile hydraulic systems, manufacturing, construction equipment, agricultural machinery and any application requiring wire‑braid reinforced hydraulic hoses within the stated media and temperature ranges.
- Helps manufacturers design and produce hose assemblies with certified performance, and enables specifiers, OEMs and procurement teams to select hoses that meet defined safety and durability criteria.
- Useful for maintenance engineers and test laboratories to verify hose performance (hydrostatic, impulse, abrasion, cold flex) against a recognized European standard.
Who should use this standard
- Hose and hose‑assembly manufacturers
- OEM designers and hydraulic system engineers
- Test laboratories and quality assurance teams
- Procurement professionals specifying hydraulic hose performance
- Certification bodies and conformity assessors

La norme EN 853:2015 spécifie les exigences pour quatre types de tuyaux en caoutchouc armés de tresses métalliques et d'assemblages de tuyaux, ayant un diamètre nominal variant de 5 à 51 millimètres. Le champ d'application de cette norme européenne garantit que ces tuyaux sont adaptés à l'utilisation avec des fluides hydrauliques conformes à la norme ISO 6743 4, à l'exception des fluides de type HFD R, HFD S et HFD T, dans un large éventail de températures allant de -40 °C à +100 °C. De plus, ces tuyaux peuvent être utilisés avec des fluides à base d'eau dans une plage de température de -40 °C à +70 °C, et avec de l'eau jusqu'à 70 °C. L'un des points forts de la norme EN 853:2015 réside dans sa précision concernant les conditions d'utilisation des tuyaux, excluant explicitement les fluides à base d'huile de ricin et d'esters, ce qui assure une sécurité accrue pour les utilisateurs. De plus, la norme clarifie qu'elle ne couvre pas les exigences relatives aux raccords terminaux, se concentrant uniquement sur les performances des tuyaux et des assemblages de tuyaux. Cela permet une spécialisation et une expertise approfondies dans la conception et l'évaluation de ces produits. La pertinence de la norme EN 853:2015 est également soulignée par son adaptation aux besoins spécifiques des applications industrielles. En définissant clairement les limites d'utilisation, elle impose des directives strictes afin de garantir la sécurité et l'efficacité des systèmes hydrauliques utilisant ces tuyaux. Il est également important de noter que la norme ne s'applique pas aux systèmes miniers souterrains, qui sont couverts par d'autres normes spécifiques, garantissant ainsi une conformité adéquate pour chaque application. En résumé, la norme EN 853:2015 répond à des critères précis de performance et de sécurité, en fournissant un cadre clair pour l'utilisation des tuyaux en caoutchouc armés de tresses, ce qui en fait un document essentiel pour l'industrie hydraulique.
The EN 853:2015 standard provides comprehensive specifications for rubber hoses and hose assemblies that are wire braid reinforced, specifically catering to hydraulic applications. The standard delineates the requirements for four distinct types of wire braid reinforced hoses with nominal bore sizes ranging from 5 to 51 mm. One of the key strengths of EN 853:2015 lies in its detailed classification of acceptable hydraulic fluids, which can include various hydraulic fluids as per ISO 6743 4-excluding HFD R, HFD S, and HFD T-allowing a temperature range of -40 °C to +100 °C. Additionally, it covers the permissible use of water-based fluids and plain water, adhering to safe operational temperature limits. This specificity ensures that users have clear guidelines for selecting appropriate hose assemblies, ultimately enhancing system reliability and safety. Another notable aspect of this standard is its clarity in scope. By stating that its applicability does not extend to end fittings, the standard focuses solely on the performance characteristics of the hoses and hose assemblies. This targeted approach aids manufacturers and users in understanding the capabilities and limitations of these hydraulic components without conflating them with additional variables such as fitting compatibility. Furthermore, EN 853:2015 offers essential notes that guide users, highlighting the unsuitability of hoses for certain fluids like castor oil-based and ester-based fluids. This ensures users do not exceed the defined limits and helps maintain the integrity of the hydraulic systems employing these hoses. In summary, EN 853:2015 stands out for its detailed specifications, clear limitations, and targeted focus on wire braid reinforced hydraulic hoses. It remains a critical reference for manufacturers and users in the hydraulic industry, ensuring safety, performance, and reliability within specified operational parameters. The relevance of this standard cannot be overstated, as it directly addresses the requirements for a safe and effective use of hose assemblies in hydraulic applications.
Die Norm EN 853:2015 bietet eine umfassende Spezifikation für Gummischläuche und Schlauchassemblies vom Typ mit Drahtgeflechtverstärkung und legt Anforderungen für vier verschiedene Arten von Schläuchen mit Nenndurchmessern von 5 bis 51 mm fest. Diese Norm ist besonders relevant für Anwendungen, die hydraulische Flüssigkeiten gemäß ISO 6743 4 verwenden, wobei Temperaturbereiche von -40 °C bis +100 °C abgedeckt werden. Ein wesentlicher Stärke dieser Norm liegt in ihrer klar definierten Anwendbarkeit für wasserbasierte Flüssigkeiten, die Temperaturen von -40 °C bis +70 °C standhalten können, sowie für Wasser bei Temperaturen von 0 °C bis +70 °C. Dies stellt sicher, dass Benutzer eine Vielzahl von Anwendungen abdecken können, während sie sich auf die Sicherheit und Effizienz der Schlauchsysteme verlassen. Besonders hervorzuheben ist, dass die EN 853:2015 nicht nur die Leistungsfähigkeit der Schläuche und Schlauchassemblies behandelt, sondern auch spezifische Einschränkungen aufweist, wie beispielsweise die Ungeeignetheit für Öle auf Rizinusölbasis und Ester-basierte Flüssigkeiten. Diese Klarstellungen sind entscheidend, um Missverständnisse bei der Auswahl von Schlauchmaterialien für bestimmte Anwendungen zu vermeiden. Die Norm umfasst zudem wichtige Hinweise über die Grenzen der Anwendung und das Verbot der Verwendung außerhalb dieser Standardspezifikationen, was der Sicherheit und Zuverlässigkeit in der Anwendung dient. Darüber hinaus ist zu beachten, dass Anforderungen für hydraulische Schläuche im unterirdischen Bergbau in separaten Normen geregelt sind, was die EN 853:2015 klar von anderen Standards abgrenzt und ihre spezifische Ausrichtung unterstreicht. Insgesamt ist die EN 853:2015 aufgrund ihrer detaillierten Vorgaben und Anwendungshinweise ein unverzichtbares Dokument für Fachleute, die in Bereichen tätig sind, in denen Drahtgeflecht verstärkte Schläuche benötigt werden.
