BS EN 856:2015规定了四种类型的橡胶包覆螺旋钢丝增强液压软管和标称孔径为6至51的软管组件的要求:4SP、4SH、R12和R13型。它们都适用于:符合ISO 6743-4的液压油，但HFD R、HFD S和HFD T除外，温度范围为-40°C至+100°C（4SP和4SH型），40°C至+120°C（R12和R13型）；温度在40°C到70°C之间的水基液体；温度范围为0°C至70°C的水溶液。本欧洲标准不包括端部配件的要求。 它仅限于软管和软管组件的性能。注1:软管不适用于蓖麻油或酯基液体。注2:软管和软管组件的操作不得超出本标准的限制。注3:地下采矿用液压软管的要求在单独的标准中进行了标准化。交叉引用:EN ISO 1302ISO 13EN ISO 1402:2009ISO 1402:2009EN ISO 4671ISO 4671EN ISO 6743-4ISO 6743-4EN ISO 6803ISO 7326EN ISO 8033:2006ISO 8033:2006EN ISO 10619-2ISO 10619-2ISO 1817:2005ISO 23529购买本文档时提供的所有当前修订版均包括在内。

BS EN 856:2015 specifies requirements for four types of rubber-covered spiral wire reinforced hydraulic hoses and hose assemblies of nominal bore from 6 to 51: Types 4SP, 4SH, R12 and R13. They are all suitable for use with:hydraulic fluids in accordance with ISO 6743-4 with the exception of HFD R, HFD S and HFD T at temperatures ranging from -40 °C to +100 °C for types 4SP and 4SH and40 °C to +120 °C for types R12 and R13;water based fluids at temperatures ranging from40 °C to 70 °C;water fluids at temperatures ranging from 0 °C to 70 °C.This European Standard does not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies.NOTE 1 The hoses are not suitable for use with castor oil based nor ester based fluids.NOTE 2 Hoses and hose assemblies are not be operated outside the limits of this standard.NOTE 3 Requirements for hydraulic hoses for underground mining are standardised in a separate standard.Cross References:EN ISO 1302ISO 13EN ISO 1402:2009ISO 1402:2009EN ISO 4671ISO 4671EN ISO 6743-4ISO 6743-4EN ISO 6803ISO 7326EN ISO 8033:2006ISO 8033:2006EN ISO 10619-2ISO 10619-2ISO 1817:2005ISO 23529All current amendments available at time of purchase are included with the purchase of this document.
