Filter standard ISO 16890
On 1 July 2018, a new filter standard came into force. EXHAUSTO retains the old item numbers, but uses the new designations in item texts, etc.

The filter is discharged of static electricity during the test
Dust load with ISO “fine dust” to find pressure loss
Filter class | Requirements | Test category | ||
