Test System for oil thread leak test of HEPA filter according to ISO 29463-4 (EN 1822-4). The oil thread test mentioned in ISO 29463-4 (1822-4), annex A is used for visual proof of the absence of leakage of HEPA filters. This simple quality test procedure may be an alternative to the scan method.
The oil thread test (DOP Test) is also applicable if the scan method is not fully applicable because of the filter design (e.g. V-shaped arrangements).
Applications
integral visual leak testing of HEPA/ULPA filters
Standards
This system complies with or supports testing according to the following international standards:
(1) ISO 16890-2: Air filters for general ventilation – Part 2
(2) ISO 16890-3: Air filters for general ventilation – Part 3: Efficiency testing
(3) ISO 16890-4: Air filters for general ventilation – Part 4
(4) ASHRAE 52.2: Method of Testing General Ventilation Air-Cleaning Devices
(5) EN 779: Particulate air filters for general ventilation
(6) ISO 10121-3: Cleanroom air filter testing
Benefits
cost-effective solution for leak testing of filters ranging up to group H (filter class H13 and H14)
easy manual operation
constant test conditions due to pre-adjustable test parameters
effective testing of larger numbers with pre-adjusted test parameters
flexible and easily configurable filter holder for different filter dimensions
Principle
The filter element (sample) is mounted horizontally with the upstream side down on the test bench and secured with a pneumatically operated fixing device. For testing, the filter is then exposed to a flow of a polydisperse aerosol of oil droplets (DEHS).
An existing leak is made visible on a rising oil thread on the downstream side (upper side) of the filter.
