The interquartile range is the range of values about the median between the upper and lower 25 pement,of all values. Section 9.5.1.1 of the Standard provides guidance addressing the impact of unusual testing conditions, including sampling, dosing,or influent characteristics, on opembon of system under test. Specific data points may be excluded from 7" and 30 -day average calculations v ere determined to have an adverse impact ort performance of the system, with rationale for the exclusion to be documented in the final report. There were no such conditions during this test. Sections 3.6 and 9.2.1 of the Standard define influent wastewater characteristics as they apply to testing under the Standard. Typical domes ic_wastewater is defined as havktg 4 CBODs concentration between 100 and 300 mglL and a suspended solids.:con entraPon between. 100 and 350 mg/L. The 30-day average influent strength remained inside this specified range for the duration of this test. 9SIf612if TMs report may not be reproduced in whole or in<part Page 11 of 49 Final Report without the expressed written consent of NSF International.
