(Note: Additions are shown in underline and deletions are shown in strikethrough.) 21 10.6 Standard Capacity Test Penetration, Pt(%). Replace Section 10.6 with the following: 10.6 Standard C

5、apacity Test Penetration, Pt(%). Compute the penetration for each time interval using Equation 10-1. Pt= 100CiCot(10-1) where: Ci= inlet (media challenge) gas concentration (in ppm) averaged over the high concentration challenge portion of the test Cot= outlet (media downstream) gas concentration (i

6、n ppm) at time “t” Since rig background concentrations must be insignificant, background corrections are not required to be made. Plot the penetration versus elapsed challenge time (beyond the conditioning period). 27 Normative Annex A. Insert Figure A-1 after Section A2.2 Example of Leakage From an

Media types indicated below: x = permanganate-impregnated activated alumina ya = acid-impregnated activated carbon yb = base-impregnated activated carbon z = virgin activated carbon, bituminous +Challenge gas shall be NO2; analysis shall be performed for both NO2 and NO. Units for Low Concentration for Carbon Dioxide are ppm. Page 3 of 3 2016 ASHRAE. All rights reserved. Figure A-1. Static leak test of ASHRAE Standard 52.2 duct after test rig sealing.
