Описание (английский):

Specifies the test procedures for, and performance requirements and marking of hydraulic brake hose assemblies to be used in hydraulic brake systems of road vehicles of which the nominal inside diameter of the hose is 3,2 mm or 4,8 mm. Applies to assemblies made of a hose fabricated from cord and synthetic elastomers and assembled with metal end fittings for use with petroleum-base brake fluids in accordance with ISO 7308.

Overview

ISO 6120:1995 - "Road vehicles - Brake hose assemblies for hydraulic braking systems used with petroleum‑base brake fluid" specifies test procedures, performance requirements and marking for hydraulic brake hose assemblies used on road vehicles. It applies to assemblies with nominal inside diameters of 3.2 mm or 4.8 mm, made from cord‑reinforced synthetic elastomer hoses assembled with metal end fittings (crimped or swaged) for use with petroleum‑base brake fluid in accordance with ISO 7308.

Key topics and technical requirements

Scope and construction

Covers hose construction: elastomeric lining, cord reinforcement plies, outer cover and permitted cushion liner; covers must resist weathering and cracking.
Assemblies must have permanently attached end fittings; end fittings are defined and may be attached by crimping or swaging.

Comprehensive test schedule

Acceptance and performance tests include: hydrostatic pressure, constriction, expansion (volumetric), burst strength, brake fluid compatibility, whip, tensile strength, water absorption, cold bend, ozone resistance (dynamic), hot impulse strength, and salt spray.
Test sample quantities and order of tests are specified; total example quantity = 36 samples for a full schedule.

Representative test parameters

Hydrostatic pressure: for inert gas/air ~10.3–14.5 MPa; for water/brake fluid ~20.7–24.8 MPa (used to detect leaks).
Burst strength and hold pressures are specified (e.g., hold at 27.6 MPa and minimum burst pressures are defined).
Expansion and constriction tests use calibrated gauge plugs and burette measurement of volumetric change at specified pressures (e.g., 6.9 MPa and 10.3 MPa test points).

Marking and identification

Requirements for marking both hoses and assembled units are provided to ensure traceability and correct application.

Applications and who uses it

Automotive OEMs and Tier‑1 suppliers designing or specifying hydraulic brake hoses and fittings.

Component manufacturers for production control, type approval and design validation.

Test laboratories and quality assurance teams performing acceptance and periodic testing to ISO 6120 procedures.

Regulatory authorities and vehicle inspectors referencing standardized test criteria for safety compliance.

Useful for anyone involved in brake system design, replacement parts manufacturing, aftermarket suppliers and fleet maintenance to ensure compatibility with petroleum‑base brake fluids.
