ISO 5898:1997 PDF

This International Standard specifies a test method for passenger car (as defined in ISO 3833) rear-window defrosting systems, when these are fitted.

It does not specify reference areas or levels of performance, since at the time it was prepared there was insufficient data available.

The test method is 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 defrosting performance:

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