ISO 9619:1992

Overview

ISO 9619:1992 specifies a standardized test method for windscreen wiping systems fitted to passenger cars. It defines how to verify wiping performance (static and aerodynamic tests) and verify functioning (frequency, stall and low‑temperature tests). The standard describes required test equipment, environmental conditions, test fluids/mixtures and the method to quantify the wiped area. Results are intended to assess visibility-related performance of wipers and washers for road‑vehicle safety and design validation.

Key topics and requirements

• Scope and applicability
  • Applies to passenger‑car windscreen wiping systems; rear‑window testing is covered by ISO 6255.
  • Tests can be omitted for vehicle types that do not differ in windscreen shape, size, surface/aerodynamic characteristics or wiping‑related system features.
• Test types
  • Static test - verifies wiped area on a stationary fixture representative of vehicle installation.
  • Aerodynamic test - performed in a wind tunnel or on a test track; equivalent results expected. Not required for vehicles with maximum speed
