Overview of Validation Process
Athalon Filters Product Overview
Athalon filter elements incorporate Pall Corporation’s advanced
filter medium pack construction that benefits from StressResistant filter medium Technology (SRT) along with othermaterial upgrades. These upgrades include specially blended
layers of fiberglass, optimized construction for low differential
pressure and stress resistance, tapered pore construction,
uniform pore size control layer and epoxy resin bonded fiberstructure. Athalon filters are rated Betax(c) > 2000.
The Athalon filter element validation process included a
Production Qualification Process and Internal Laboratory Filter
Testing per ISO Filter Test Standards.

Production Qualification of Athalon Filter Elements
A Production Qualification process was carried out on theAthalon filter elements in order to confirm manufacturing
process capabilities, clarify SPC (Statistical Process Control)
requirements for defined critical to quality measurements,
clarify the requirements for releasing Athalon work cells for
production and document requirements for production atPall manufacturing sites. Upon successful completion of theProduction Qualification process, representative Athalon filter
element samples were manufactured for internal laboratory
filter testing.

Pall Internal Laboratory Testing
Internal laboratory filter testing per ISO Filter Test Standards
on the Athalon filter elements was conducted in order togenerate product performance claims and specifications.
All testing is complete and the results show that the Athalon
filter elements have met the performance goals.
This internal laboratory testing included:
1. Material Compatibility per ISO 2943 - Verified by heatsoak for 72 hours at 15°C (27°F) higher than the above
rated maximum temperatures in a series of fluids andqualified by similarity to Ultipor® III and Ultipleat® SRTfilter element materials.
2. Fabrication integrity per ISO 2942, “Hydraulic fluidpower – Filter elements – Verification of fabrication
integrity and determination of the first bubble point”.
3. Clean Element differential pressure per ISO 3968 		
- “Hydraulic fluid power – Filters − Evaluation of 		pressure drop vs. flow characteristics”.
4. Filtration ratios and dirt capacity per ISO 16889, 		“Hydraulic fluid power filters – Multi-pass method forevaluating filtration performance of a filter element”.
5. Collapse ratings per ISO 2941, “Hydraulic Fluid Power– Filter Elements – Verification of collapse/burst 		resistance”.
6. Stress-Resistance Test and Cyclic Stabilization ratings
per SAE ARP 4205, “Aerospace fluid power – Hydraulicfilter elements – Method for evaluating dynamic 		
efficiency with cyclic flow”.
