ISO 17165-1:2007

Overview

ISO 17165-1:2007 is an international standard developed by the International Organization for Standardization (ISO) that specifies the dimensions and requirements for hydraulic fluid power hose assemblies. This standard ensures that hose assemblies - constructed from hoses conforming to ISO 3949, ISO 1436, ISO 3862, ISO 4079, and ISO 11237 and equipped with hose fittings featuring elastomeric seals per ISO 12151 series - meet performance, safety, and compatibility criteria for hydraulic applications.

The document provides key criteria for selecting preferred hose and fitting types, ensuring compatibility and reliability in hydraulic systems. It also outlines the essential tolerances, manufacturing requirements, and marking for hose assemblies to support safety and efficiency.

Key Topics

• Scope and Application: Specifies requirements for hose assemblies used in hydraulic systems, including dimensions, working pressures, and hose fitting types with elastomeric seals.
• Compatibility: Ensures hoses and fittings are compatible by referencing multiple ISO standards (e.g., ISO 12151-1, ISO 12151-2, ISO 12151-3, ISO 12151-6).
• Designation and Marking: Outlines designation methods for hose assemblies and specifies requirements for durable and clear product marking, including manufacturer, pressure rating, and assembly date.
• Dimensional Requirements: Details nominal inside diameters, maximum working pressures, bend radii, and corresponding steel tube sizes.
• Manufacturing Practices: Requires documented manufacturing instructions, including preparation, assembly, and post-assembly inspection, to prevent leaks and ensure quality.
• Tolerances and Testing: Prescribes tolerances for assembly length and rotational angle, and directs that hose assemblies be tested as per relevant standards.
• Pressure Drop Considerations: Advises on the effect of hose fitting design on system pressure drop, emphasizing the importance of appropriate measurement and selection.

Applications

ISO 17165-1:2007 is crucial for industries and professionals involved in hydraulic fluid power systems, including:

• Industrial Hydraulics: Used in factories, manufacturing lines, injection molding equipment, and automated machinery where high-pressure hydraulic hose assemblies ensure safe and efficient fluid transmission.
• Mobile and Heavy Equipment: Applied in construction equipment, agricultural machinery, and mining vehicles for power transmission and movement control.
• Maintenance and Safety: Assists maintenance managers and safety inspectors in selecting, installing, and verifying reliable hose assemblies that comply with international quality and safety benchmarks.
• Hose Manufacturing and Assembly: Guides hose assemblers and OEMs (Original Equipment Manufacturers) in the selection, assembly, and verification of compatible hoses and fittings for new builds or repairs.
