This part of ISO 8153 defines terms used for all types of hose assemblies. General terms can be made more precise through the addition of supplementary terminology relating to the design, range of application and/or the material of the hose/hose assembly. Terms and definitions specific to metallic hose assemblies are given in ISO 7369. NOTE Certain concepts used in this part of ISO 8153 are not applicable to all types of hose assemblies, but only to specific types, e.g. the term “insert” does not apply to a flexible metal hose without an insert as defined by this part of ISO 8153.
