ISO 3469:1989/Amd 1:2006

Overview

ISO 3469:1989/Amd 1:2006 is an important amendment to the original ISO 3469:1989 standard, focusing on passenger cars' windscreen washing systems and their specific test methods. Issued by the International Organization for Standardization (ISO), this amendment refines testing procedures to ensure greater accuracy, reliability, and consistency in evaluating windscreen washing systems for passenger vehicles. The standard targets automotive manufacturers, testing laboratories, and safety authorities aiming to enhance vehicle visibility and safety through standardized assessment protocols.

Key Topics

• Windscreen Washing Systems: The amendment applies to the evaluation of systems designed to maintain windshield clarity by effectively dispensing and cleaning automotive windscreens.
• Test Methods: Specific procedures and methodologies are described to test the efficiency, functionality, and performance of washing systems under controlled conditions.
• Amendment Focus: Changes introduced in Amendment 1 primarily address modifications in the test mixture used during assessments:
  • The title of Annex A is changed to "Test mixture."
  • Removal of the initial paragraph that previously guided the selection of test mixtures.
  • Elimination of section A.1 and its associated footnotes.
  • Removal of the title for section A.2, simplifying the structure and presentation of the test mixture information.
• Technical Committee Involvement: Developed by ISO/TC 22, Road Vehicles, Subcommittee SC 17 on Visibility, highlighting the document’s authority in vehicle safety and visibility standards.

Applications

• Automotive Manufacturing: Vehicle manufacturers use ISO 3469 to verify that windscreen washing systems meet performance and safety requirements before production.
• Quality Assurance: Testing laboratories adopt the standard’s prescribed test methods to certify systems’ reliability and compliance.
• Regulatory Compliance: Regulatory bodies and safety inspectors refer to this standard for vehicle inspection and type approval processes.
• Product Development: Engineers and designers improve the efficacy of windscreen washing systems based on the standardized test results, ensuring optimal windshield cleanliness and driver visibility.
• Safety Enhancement: By standardizing testing procedures, the amendment supports the development of safer passenger cars, reducing accidents linked to poor visibility due to ineffective windscreen cleaning.

Related Standards

• ISO 2575 - Road Vehicles - Symbols for Controls, Indicators and Tell-Tales
• ISO 3888 - Road Vehicles - Lateral Guidance of Vehicles on Test Tracks
• ISO 6469 - Electrically Propelled Road Vehicles - Safety Specifications
• ISO 15055 - Road Vehicles - Test Procedures for Windscreen Wiper Systems

These related standards collectively contribute to improving vehicle visibility and safety through clear guidelines, complementing the windscreen washing system test methods.

By adhering to ISO 3469:1989/Amd 1:2006, stakeholders in the automotive industry can ensure that windscreen washing systems are evaluated rigorously, contributing to safer driving environments and enhanced visibility under various conditions. This amendment represents a critical update that streamlines testing procedures and clarifies the composition and use of test mixtures for more consistent and meaningful test outcomes.
