938 TA. iV-4000 Procedural Guidelines:
(a) For each moisture separator, prefilter, and HEPA fi lter. measure the air velocity at the approximate centers of equal areas with at least one
meaSuremen! per each moisture separator. pre filter. and HEPA niter. and a minimum of 9 measurements per bank. Adso"r velocity
measurements shall be made in the approximate center of the flow slots. For low slots greater than 24 inches long (60 cm), measurements shall
be nominally eve ry 12 inches (30 cm) a lo ng the length of the slot.
(b) Ca lc ulate the average velocity (V,,,) using the following formula:
V... LV; / n
where
LV, a sum of Individual velocity readings
n • number of readings
(c) Identify the highest and lowest velocity readings and calculate the percentage they va ry from t e average calculated above.

939 TAN-1100 System Test:
Injection and sample Pon location sna p be located so that the enti re system, including housing bypass ducts and associated dampers, Is
challenged for inadve rtent bypass flow paths around the HEPA filter or absorber banks. If this cannol be accomplished, and integrated system lest
shall be included in addition to the bank rests o0inedl in Mandatory Appendices TA-V( TA-VII. ane TA-4940.
940 TA-V.1300 lnfecl'on PW Selection Criteria:
Injection pons should be located upstream of a flow disturbance to maximize mixing. The crallenge gas will pass through the HEPA bank and
challenge the absorber bank. For systems with two or more HEPA fi lter banks in series, or two or more absorber banks in se ries • separate
injection pons must be qualified for each bank. Use of injection manifolds may be necessa ry when the re is insufficient room between banks to
provide adequate mixing,
941 TA-V-2000 Prerequisites
The system is operating within +/•10°6 of design !low rat e . rho airflow distribution has been verified in accordance with Mandato ry Appendix TA-
IV
942 TA-V-4000 JProcedural Guidelines:
I (a) Connect challenge aerosol or gas generator to the injection po rt to be toslec.
(b) Place the challenge ae ro sol or gas measuring Instrument sample p ro be upstream of the bang tb be tested with adequate hose length to reach
an areas of the bar*._
(c) Stan the challenge ae ro sol or gas injection and establish a constant injection rate.
(d) Take a concentration reading upstream of and at the approximate centers of equal areas, with at least one reading per HEPA filter and a
minimum of 9 readings per HEPA bank. For ty pe n and type III adsorbe rs, readings shall be taken upstream of and In the app roximate center of
each flow slot. For now slots greater than 24 inches (60 cm) in le ngth, a reading shall be taken romina ; ly eve ry 12 inches (30 cm) along the length
Of the slot.
943 TA•V-4000 Procedural Guide lines:
(e) Calculate the average concentration (C,,,) readings using the following formula:
1 C.,• - LC;1 n
where
LC, % sum of Individual velocity readings
n . number of readings
(f) identify the highest and lowest concentration readings and calculate the pe rc ,:s"
entage they va ry from the average calculated above.
