Hose and hose assemblies covered by this specification are intended for use in equipment hydraulic systems at temperatures ranging from −40°F to 200°F. Hoses, type 100R are designed for ground vehicles, hydraulic test stands, and similar uses. They are not intended for aircraft use. These military unique hoses and hose assemblies are used in vehicle hydraulic systems requiring interoperability and compatibility with associated components, in combat or harsh environments. In the range of temperatures from −40F to 200°F this interoperability and compatibility has been assured through the strict adherence to military requirements which contain a substantial amount of detail. The detail assures item standardization and compatibility through specific dimensions, and tolerances in the MIL-DTL-52471 specification sheets and material control requirements in this specification. The qualification process ensures these items will perform under the extremes of the environments in which they are used. Users and prime equipment manufacturers depend on these detailed technical requirements to ensure delivered products meet the interoperablility and compatibility requirements.
