.4.1 Testing of IIEPA Filter Banks.
Perform the following steps on the high efficiency filter systems listed below and attach a completed test report for each filter .m - system to this procedure. , 4.1.1 ~ Establish ai[ flow through the' filter being tested. Measure and . record the resistance across the filter bank. . 4.1.2 Connect the penetrometer sampling line to upstream sampling port . and calibrate it against its built-in standard in accordance with t,he manufacturer's instruction. 2~ ' 4.1.3 For an' acceptance test of a new system, check the background dust concentration upstream and dounstream of the filters; the bdck- [
- ground dust concentration shall be Icss than 257. of the expected aerosol concentration during the test. .r -

the upstream reading. It may prove in larger systems a lower or 1f i s
'different scale reading is necessary to establish an upstream reading.

T l 4.2.3 Conhect the sample lines to upstream and downstream sample points, establish detcetor operating conditions used in their calibration, establish . upstream dilution-air rat o to produce an upstream con-centration at the tracer gas detector which is within the linear
)J response range.
4.2.4 Take upstrena background samples and downstream background sampics , {g ,(5 minimum for noncontinuous detectors). If these show no back- . ground contaminants that might interfere with the test results,
; continue with the test. If downstream interference;is too great to .
1 obtain a base line, purge the bank at rated system air flow for 8

to 12 hours, or change tracer gas.
! 4.2.5 Estimate the tracer gas transit time from the generator on through , , i the injection port and system to the detector. Start the injection and after the estimated transit time, monitor the upstream concen-7 tration. The time when the initial tracer gas is detected is des-j ignated as time zero tracer gas R-11. .-* 4.2.6 Calculate the Icakage for cach time interval from the equation: % Leakage Where L = 100 gd_ ' with L = % Icakage Cu r- "

Rev.1 ._ ACCEPTANCE CRITERIA 5.1 Each IIEPA filter bank, except for those specified in step 5.3, shall have a miximum Icakage of 0.057. (cf ficiency of 99.957.) or as specified by the Contractor, based on the actual number of ,particules that pen-ctrate the filter when using the polydisperse acrosol, gen'erated from a liquid DOP having a particle diameter of 0.75 + 0.50 micron. , 5.2 Each iodine adsorber bank si'all have an in-place maximum leakage of 1.07. (ef ficiency of 99.0%), or #a s specified by the Co tractor, based on the differential zero time concentration of the upstream and down-
. stream sampics. It is understood that the test shous only acchanical i- Icak and does not- represent actual clemental iodine of methyl iodide ,
