1173 11.1 Purpose:
This test shell be used for both acceptance and su rveillance leak testing of the installed adsorber bank. It samples of adsorbent are to be taken
for laboratory testing Section 15). remove such samples rior to this test. and restore bank to 0 erati co ndition.
1174 11.2 Summary a Method'
A ha lide challenge gas is Injected into the airstream upstream of the absorber bank. Concen trations shall be determined upstream and
downstream of the bank. Percent penetration Is determined from the rat 'o of downstream to upstream concentral:on rSectlon 3 .

NOTES:
1) Sample line lengths should be minimized to reduce sample response time and of equal lengths to eliminate time delay er ro rs.
2) It may be necessa ry to operate system for a pe riod to purge all resldual challenge gas fro m a prior lest to reduce background
