Rubber hoses and hose assemblies - Wire- or textile-reinforced single-pressure types for hydraulic applications - Specification (ISO 18752:2022)
This document specifies requirements for ten classes, four grades and seven types of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 102. Each class has a single maximum working pressure for all sizes.
They are suitable for use with:
— 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 for types AS, AC, BS and BC hoses and from −40 °C to +120 °C for types CS, CC and DC hoses.
— water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743‑4 at temperatures ranging from −40 °C to +70 °C.
— water at temperatures ranging from 0 °C to +70 °C.
This document does not include requirements for the connection ends. It is limited to the performance of hoses and hose assemblies. The hose assembly maximum working pressure is governed by the lowest maximum working pressure of the components.
NOTE It is the responsibility of the user, in consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used.
Gummischläuche und -schlauchleitungen - Draht- oder textilverstärkte Einzeldrucktypen für hydraulische Anwendungen - Spezifikation (ISO 18752:2022)
Dieses Dokument legt Anforderungen an zehn Kategorien, vier Klassen und sieben Typen von draht- oder textilverstärkten Hydraulikschläuchen und -schlauchleitungen mit Nenngrößen im Bereich von 5 bis 102 fest. Jede Kategorie hat bei allen Größen einen einzigen maximalen Betriebsdruck.
Sie sind für den Gebrauch mit:
— ölbasierten Hydraulikflüssigkeiten HH, HL, HM, HR und HV geeignet, wie in ISO 6743 4 festgelegt, bei Temperaturen im Bereich von −40 °C bis +100 °C für Schläuche der Typen AS, AC, BS und BC und von −40 °C bis +120 °C für Schläuche der Typen CS, CC und DC;
— den in ISO 6743 4 festgelegten wasserbasierten Flüssigkeiten HFC, HFAE, HFAS und HFB in einem Temperaturbereich von −40 °C bis +70 °C geeignet;
— Wasser bei Temperaturen im Bereich von 0 °C bis +70 °C geeignet.
Dieses Dokument enthält keine Anforderungen an die Anschlussstutzen. Es ist auf die Leistung von Schläuchen und Schlauchleitungen begrenzt. Der maximale Betriebsdruck einer Schlauchleitung wird durch den geringsten maximalen Betriebsdruck der Komponenten bestimmt.
ANMERKUNG Es liegt in der Verantwortung des Benutzers, in Absprache mit dem Schlauchhersteller, die Verträglichkeit des Schlauches mit der Flüssigkeit, die verwendet wird, sicherzustellen.
Tuyaux et flexibles en caoutchouc - Types hydrauliques à pression unique, avec armature de fils métalliques ou textiles tressés - Spécifications (ISO 18752:2022)
Le présent document spécifie des exigences pour dix classes, quatre grades et sept types de tuyaux et flexibles hydrauliques avec armature de fils métalliques tressés de dimensions nominales comprises entre 5 et 102. Chaque classe a une pression maximale de service unique pour toutes les dimensions.
Ils sont adaptés pour une utilisation avec:
— des fluides hydrauliques 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 pour les tuyaux de types AS, AC, BS et BC et de –40 °C à +120 °C pour les tuyaux de types CS, CC et DC.
— 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 −40 °C à +70 °C.
— de l’eau pour une plage de températures de 0 °C à +70 °C.
Le présent document ne contient pas d'exigences relatives aux extrémités de raccordement. Il se limite aux performances des tuyaux et flexibles. La pression maximale de service du flexible. La pression maximale de service du flexible est régie par la plus faible pression maximale de service des composants.
NOTE Il est de la responsabilité de l'utilisateur, en concertation avec le fabricant de tuyaux, d'établir la compatibilité du tuyau avec le fluide destiné à être utilisé.
Gumene cevi in cevni priključki - Vrste hidravličnih cevi in priključkov, ojačenih z žico ali tekstilom, z enojnim delovnim tlakom - Specifikacija (ISO 18752:2022)
Ta dokument določa zahteve za deset razredov, štiri skupine in sedem vrst s tekstilom ojačenih hidravličnih cevi in cevnih priključkov z nazivno velikostjo od 5 do 102. Vsak razred ima en sam največji delovni tlak za vse velikosti. Primerni so za uporabo s/z: – hidravličnimi tekočinami na oljni osnovi HH, HL, HM, HR in HV, kot je opredeljeno v standardu ISO 6743-4 pri temperaturah od –40 °C do 100 °C za vrste cevi AS, AC, BS in BC ter od –40 °C do 120 °C za vrste cevi CS, CC in DC; – tekočinami na vodni osnovi HFC, HFAE, HFAS in HFB, kot je opredeljeno v standardu ISO 6743-4 pri temperaturah od –40 °C do 70 °C; – vodo pri temperaturah od 0 °C do 70 °C. Ta dokument ne vključuje zahtev za priključne konce. Standard je omejen na učinkovitost cevi in cevnih priključkov. Največji delovni tlak cevnega priključka je določen z najnižjim maksimalnim delovnim tlakom elementov. OPOMBA: Uporabnik mora po posvetovanju s proizvajalcem cevi določiti združljivost cevi z uporabljeno tekočino.
