Overview
ISO 17447-3:2015 is an international standard published by ISO that specifies the tests and requirements for sheath-type glow-plugs with conical seating and their cylinder head housings. It applies to glow-plugs conforming to ISO 17447-1 and ISO 17447-2, mainly used in diesel (compression ignition) engines. This standard ensures glow-plugs meet reliable performance standards through comprehensive testing methods agreed upon by glow-plug manufacturers and engine manufacturers.
The standard replaces earlier individual standards for glow-plugs by consolidating test procedures and requirements into one document, enabling consistent quality, durability, and functional performance across the automotive industry.
Key Topics
ISO 17447-3 covers critical aspects of glow-plug testing and performance, including:
Gas Tightness Test
Ensures the glow-plug sheath resists gas leakage under pressure (4 MPa), maintaining engine integrity with a maximum allowable leakage of 2 cm³/min.Thermal Characteristics
Defines how glow-plugs heat up and maintain temperature. Testing includes measuring the hottest point within a designated zone and ensuring agreed temperature/time profiles for reliable ignition.Electrical Resistance Testing
Measures the glow-plug's electrical resistance at room temperature, an important indicator of its health and performance.Current Characteristics
Records the electrical current consumed during startup and thermal equilibrium to verify consistency and efficiency under operation.High Voltage Endurance
Tests glow-plugs at 130% of nominal voltage for 15 seconds to assess durability under higher than normal electrical stress.Vibration Testing
Uses sinusoidal vibration tests according to IEC 60068-2-6 to simulate engine conditions, ensuring mechanical robustness and resistance to vibration-induced failure.Endurance Testing
Long-term cycling tests under agreed conditions evaluate the glow-plug's lifecycle and reliability in real-world operational environments.Marking and Labeling
Requires permanent marking of nominal voltage and manufacturer identification to support traceability and standard compliance.
Applications
ISO 17447-3:2015 is essential for:
Diesel Engine Manufacturers
Ensuring glow-plug components meet stringent test requirements for performance and durability in high-compression engines.Glow-plug Manufacturers
Guiding production and quality assurance processes through standardized testing and performance benchmarks.Automotive Component Suppliers
Validating parts compliance for integration into diesel vehicle cylinder heads, promoting interchangeability and reliability.Testing Laboratories
Implementing standardized assessment protocols for gas tightness, thermal behavior, electrical resistance, and vibration resilience.
By adhering to ISO 17447-3, stakeholders can enhance diesel engine cold start efficiency, minimize emissions, and improve overall engine performance.
Related Standards
ISO 17447-3 is part of the ISO 17447 series focused on glow-plugs:
