Passenger cars. Windscreen defrosting and demisting systems. Test method
This International Standard specifies the test method for passenger car (ISOĀ 3833:1977, 3.1.1) windscreen defrosting and demisting systems, when these are fitted.
This International Standard does not specify reference areas or levels of performance.
The test condition of ā18 °C ± 3 °C specified for defrosting systems will meet the majority of cold climatic requirements.
The tests for demisting systems are conducted at a temperature of ā3°C ± 1°C, since this is the practical minimum temperature at which mist, as defined in 3.7, can normally occur.
