Automotive Windshield Washer Nozzle Fatigue Testing Machine
The Windshield Washer Nozzle Fatigue Test Machine is designed to evaluate the durability and performance of automotive nozzles, including windshield cleaning nozzles (WCS) and headlamp cleaning nozzles (HCS). The machine operates within a controlled environmental chamber, allowing you to simulate temperature and fluid conditions while performing long-term fatigue tests on multiple components simultaneously. Its integrated control and data acquisition system ensures precise monitoring and reliable results.
Standards
The machine complies with international and national automotive testing standards, including:
ISO 6255:1997 – Passenger car windscreen washer systems – Test methods
SAE J942:1999 – Performance requirements and test procedures for passenger car windscreen washing systems
GB 15085‑2013 – Performance requirements and test methods for automotive windshield wipers and washer systems
GB/T 23436‑2009 – Automotive windshield cleaning fluid testing specification

Test Procedures
Install nozzles or components to be tested inside the test chamber.
Connect the working fluid supply (water-ethanol mixture).
Set desired environmental temperature and operational cycles.
Start the test using the PLC-based control unit.
Monitor real-time system parameters including chamber temperature, fluid flow, and nozzle operation.
The machine records all data automatically for later analysis.
After the test, safely remove the components and review recorded fatigue performance.
Maintenance Information
Regularly inspect fluid lines and nozzles to prevent blockage or residue accumulation.
Check nitrogen generator and explosion-proof suction system for proper operation.
Calibrate temperature and pressure sensors periodically for accurate measurements.
Clean the test chamber to remove flammable vapors and fluid residue.
Verify PLC control software and data acquisition integrity before each test cycle.
