Scope

This part of ISO/TS 11155 specifies a particulate filtration test, including the critical characteristics of equipment,
test procedure and report format, for the consistent assessment of filter elements in a laboratory test rig with
particle sizes larger than 0,3 μm. It is applicable to filters for removing particulate matter from external or
recirculated air used for ventilating motor vehicle passenger compartments or cabins.
The test specified in this part of ISO/TS 11155 enables an assessment of filter elements for pressure loss,
fractional filtration efficiency and accelerated particulate holding capability against standardized laboratory
particulate challenges. Because the test methods exclude the full range of possible particulate challenges and
environmental effects, the relative ranking of filters may change in service.
NOTE 1 Absolute comparability is only possible with filter elements of the same shape and size as well as the same position
in the test duct.
NOTE 2 Subject to agreement between supplier and the customer, the test procedure allows for the calculation of
gravimetric efficiency as a single parameter for quality control purposes. For gravimetric efficiency tests refer to ISO 5011.
