Vehicle Ventilation Filters - Influence of Test Set-Up and Parameters on Performance Results
Published May 09, 1995 by Institution of Mechanical Engineers in United Kingdom
Cabin air filters for motor vehicles became a standard during the recent years. This article gives an overview of the reasoning for a related test methodology. This means to identify sets of performance parameters to be tested for different product types, furthermore, we will describe the test regimes under discussion. The relevance of the currently discussed test conditions for practical applications is discussed for particle filters, an alternative relating the obtained results more closely to practical conditions of use is proposed. As adsorptive filters for this market are a quite recent development experience with test regimes has to be gathered, still. Therefore, more basic questions regarding parameters potentially affecting the test results are discussed.
