ASHRAE Standard 52.2 test score of greater than 65 + 1.645*SR must be obtained. SR is the Reproducibility Standard Deviation from ASHRAE 1088-RP. The 1.645 multiplier is used to calculate the 5th percentile of a normal distribution and is used to calculate a 95% lower confidence bound. ANSI/ASHRAE Addendum i to ANSI/ASHRAE Standard 52.2-2012 1 (This foreword is not part of this standard. It is merely informative and does not contain requirements necessary for conformance to the standard. It has not been pro-cessed according to the ANSI requirements for a standard and may contain material that has not been subject to Standard 52.2-2012 as of the publication of the 2015 Supplement. Interpretation: My interpretation of Section 12.3 is that a MERV based on the 2015 Supplement Table 12-1 is acceptable for any ASHRAE Standard 52.2 test data set that meets the requirements of Standard 52.2-2012 with the 2015 Supplement.
