This International Standard specifies test methods for passenger car (as defined in ISO 3833) rear-window washing and wiping systems, when these are fitted, excluding convertible passenger cars with rear-windows made of plastic.

This International Standard does not specify reference areas or levels of performance, since at the time it was prepared there was sufficient data available.

The test methods are intended to apply to types of power-driven vehicles which do not differ from one another in respect of the following essential features which affect washing and wiping performance:

• shape, size and surface characteristics of the rear-window;
• characteristics of each system designated by the vehicle manufacturer as contributing to the washing and wiping of the rear-window.
