Overview
ISO 17324:2014 - Rubber hoses for automotive turbochargers - Specification defines requirements for rubber hoses used in automotive turbocharger systems. It covers hoses that connect the turbocharger, intercooler and internal combustion engine, specifying allowable working temperatures (−40 °C to +250 °C) and working pressures (−0,01 MPa to 0,5 MPa). Hoses may be straight or shaped and are detailed by type, construction, materials, dimensions, physical properties and required tests.
Key Topics
- Scope and classification
- Type A: air filter → turbocharger (−40 °C to +100 °C; vacuum to −0,01 MPa).
- Type B: turbocharger → intercooler (pressurized, heated air); subtypes B1/B2/B3 by temperature and classes by pressure.
- Type C: intercooler → engine (pressurized, cooled air; up to +140 °C).
- Grades by fatigue resistance
- Grade 200 = 200,000 impulse cycles; Grade 400 = 400,000 cycles.
- Materials and construction
- Typical elastomers: EPDM, CR, AEM, ACM, VMQ, FKM, etc.; reinforcements include textile (PET, PA) and aramid (AR) or wire.
- Hoses comprise a lining, reinforcement, and cover; options include smooth or corrugated profiles, insulation, and abrasion jackets.
- Dimensions and tolerances
- Inside diameter, wall thickness and length tolerances (per ISO 4671); end squareness requirements.
- Physical and performance requirements
- Compound property tests: heat ageing (ISO 188), low‑temperature brittleness (ISO 812), oil resistance (ISO 1817), ozone resistance (ISO 1431‑1).
- Hose tests: vacuum resistance (Type A), proof and minimum burst pressures (Type B & C) per ISO 1402, adhesion (ISO 8033), fatigue resistance (Annex A).
- Marking, storage and testing frequency
- Requirements for identification, recommended production tests and routine/type testing procedures.
Applications
ISO 17324:2014 is directly applicable to:
- OEMs and Tier 1/2 suppliers designing or sourcing turbocharger intake and boost hoses.
- Quality and test engineers validating hoses against temperature, pressure, fatigue and chemical exposure criteria.
- Materials engineers selecting elastomers, reinforcements and protective jackets for high-temperature, high-pressure boost circuits.
- Procurement and regulatory teams requiring standardized specifications for compatibility and reliability in turbocharged engines.
Practical use cases include charge‑air transfer between turbocharger, intercooler and intake manifold, and replacement/aftermarket hose specification.
