ISO/TS 17165-2:2018
Hydraulic fluid power — Hose assemblies — Part 2: Practices for hydraulic hose assemblies
ISO/TS 17165-2:2018 provides guidelines for selection, routing, fabrication, installation, replacement, maintenance and storage of hose and hose assemblies for hydraulic fluid power systems which are manufactured from hoses conforming to ISO 1436, ISO 3862, ISO 3949, ISO 4079 and ISO 11237, and hose fittings conforming to the ISO 12151 series.
NOTE 1 Many of these practices also can be suitable for use with other types of hoses and systems.
NOTE 2 Annex A lists examples of actual failure resulting from improper use of hydraulic hose and hose assemblies.
