  17. 17. • MPPS (Most Penetrating Particle Size) is normally in range 0.1-0.25 micron for HEPA/ULPA filters• Air Velocity* through filter media and type of filter material determine: – MPPS – Efficiency – Pressure drop *= Note the difference between media air velocity and filter face velocity
  18. 18. • MPPS (Most Penetrating Particle Size) is normally in range 0.1-0.25 micron• Filters have historically been tested at various sizes – 0.17 µm - Soda salt test (AFNOR X44-1) – 0.30 µm - DOP test (Q107 or MIL282) – 0.65 µm - Sodium flame (BS3928)• Today MPPS is introduced (EN 1822)

  31. 31. Filter elements of Group HCan be tested using one of three leak test methods: -• The reference scanning method EN 1822-4• The Oil Thread Leak Test (EN 1822-4:2009, Annex A)• The 0.3mm – 0.5mm Particle Efficiency Leak Test (EN1822- 4:2009, Annex E, for Class H13 only)All leak tests shall be performed at the nominal/rated air flow of thetest filter element.
  32. 32. BS/EN 1822:2009Filter shapes creating highly turbulent air flow (eg V-bank or cylindricalfilters) for which the reference scan method can not be applied, should beleak testing by either of the two alternative methods:1. Oil Thread Leak Method (EN 1822-4:2009, Annex A) or 0.3mm – 0.5mm m m2. Particle Efficiency Leak Test (EN1822-4:2009, Annex E, for Class H13 only)For higher Classes of filters, the two alternative methods might not besensitive enough to measure the local penetration limits.Higher Classes of filters have to be marked:-1. “Alternative leak tested, method A” or2. “Alternative leak tested, method E” on its label and test report

  37. 37. Particle counter• Digital output• Typical size range 0.1-5.0 µm• Typical Sample flow 0.1-1.0 CFM• Diluter needed to measure high upstream concentration• Penetration range : practical min 0.000001%
  38. 38. Photometer• Analouge output• Typical concentration range: 10-100 mg/m3• Penetration range : 100-0.001%
  39. 39. Particle counter Photometer+ high sensitivity + high concentrations+ size distribution + leak quantifcation+ MPPS – medium sensitivity– sensitive to high – no direct sizing (no MPPS) concentrations – need high aerosol– leak quantification concentration – Result may depend on aerosol distribution
  40. 40. Today, normally particle counters are used for factory test (EN 1822 or similar)• Better sensitivity• Scanning and total efficiency at same test• Various aerosols can be used• Test at MPPS (EN 1822)
  41. 41. For In-Situ test both DPC’s and Photometers can be usedParticle counter Photometer• Sensitive • Fast quantification• Used where liquid aerosols are • Less sensitive unwanted • OK for check of gaskets, etc• Same instrument as in EN 1822 • Today, basically only for• Normal penetration will be leaks. measured (MPPS)
  42. 42. Comparison of Particle counters/photometer result• Not same measurement technique• Photometer is aerosol dependent
  43. 43. Distribution of DOP and efficiency of class H13, 99.95% MPPS • Comparison of Particle counters and photometer LASKIN - Weight distribution Hot DOP - Weight distribution result penetration - Absolute filter • Two aerosol distributions 50.00 1.00E+00 • The penetration curve is 45.00 1.00E-01 measured by particle 40.00 1.00E-02 counterfreqvency/µm [%] penetration [%] 35.00 1.00E-03 30.00 • Photometer result can 1.00E-04 25.00 differ depending on aerosol 1.00E-05 20.00 1.00E-06 15.00 10.00 1.00E-07 5.00 1.00E-08 0.00 1.00E-09 0.01 0.1 1 particle size [µm]
  44. 44. • Efficiency (overall) – Overall particle efficiency can be measured with static probe or by integrating the data from scanning• Scanning - Leaks – Scanning is performed over filter surface - leak check

  47. 47. • Important, measurement • Important, data – No false leaks – Print outs – Probe speed – Database integrity – Aerosol concentration – Aerosol distribution – Diluter – Instrument performance (Particle counter) – Statistical considerations – Particle losses in system
  48. 48. ISO 14644, suggestFor filters < 99,995% (H14) photometers can be used• Aerosol distribution with mass mean diameter between 0.5-0.7 µm• Leak designated as 0.01%For filters >99.995% particle counters should be used• DOP/DEHS challenge• Leaks designated as > described in EN 1822
  49. 49. • Photometers and particle counters can be used for leak testing filters• EN 1822 is now in use (2000-09-01) for factory test• EN describes test method, equipment and classification of HEPA/ULPA filters• Be aware of the differences in measurement technique (Photometer/EN1822/other tests)• Communicate with customer (should filter be tested? Which test method is required from customer? Make sure he/she understand how Camfil test)• Requirements/test methods in situ at customer can be different (ex. Safety cabinets, pharmaceutical industry)
