Consensus is defined by the AmericanNational Standards Institute (A

6、NSI), of which ASHRAE is a member and which has approved this Standard as an ANS, as “substantial agreement reached by directlyand materially affected interest categories. This signifies the concurrence of more than a simple majority, but not necessarily unanimity. Consensus requires that allviews a

ASHRAE obtains consensus through participation of its national and international members,

8、associated societies, and public review.ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the Standard. The Project Committee Chair andVice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, all must b

It has not been pro-cessed according to the ANSI requirements for a standardand may contain material that has not been subject topublic review or a

25、consensus process. Unresolved objec-tors on informative material are not offered the right toappeal at ASHRAE or ANSI.)FOREWORDThese proposed MERV table changes are a direct result of athorough review and series of votes at the committee level toaddress key issues about the variability of the standa

26、rd, spe-cifically the MERV 8 through 11 overlap issue and the needfor each range to be consistent with the lower limits of theother ranges. These inconsistencies have been a source oflegitimate confusion and have been used to abet the knownoccasional intentional misuse of the data. It is our sincere

27、belief that these steps are critical in the further use of thestandard and its data product. Further and substantialchanges in the MERV concept are under consideration nowand should compliment these proposed changes.Note: In this addendum, changes to the current standardare indicated in the text by

28、underlining (for additions) andstrikethrough (for deletions) unless the instructions specifi-cally mention some other means of indicating the changes.12. MINIMUM EFFICIENCY REPORTING VALUE(MERV) FOR AIR CLEANERS12.2 The minimum final resistance for an air cleaner shall bein accordance with Table 12-

Air cleaners with MERV1 toMERV4 (i.e.,

30、 devices with efficiencies less than 20% in thesize range of 3.010.0 m) shall also be tested in accordancewith the Dust-Loading Procedure outlined in Section 10.7.2 ofthis standard before using this system for reporting.Addendum a to Standard 52.2-2012Modify Section 12, replacing Table 12-1, as foll

EXAMPLES.D2.4 “Filter D”The reporting value for this air cleaneris MERV8 at 0.93.This minimum performance curve is typical of a mediaair clean

35、er currently marketed as a 25% to 30% dust spot fil-ter when tested at 0.93 m3/s (1970 cfm). The range efficien-cies are calculated as follows:The average efficiency in Range 3 is in the 80% to -below the85% range minimum shown in Table 12-1 for theMERV Group 109-12 category. However, the E2 value i

36、sabove the 20% required for MERV 8 and below the 35%required for MERV 9. Thus, the MERV of this filter This fil-ter is categorized in the MERV Group 5-8 area because theaverage in Range 3 is above the MERV Group 1-4 area. Theaverage efficiencies in Ranges 1 and 2 are not used for report-ing. Based o

37、n the average efficiency of 81% in Range 3, thisfilter is reported as MERV8 at 0.93.INFORMATIVE APPENDIX JOPTIONAL METHOD OF CONDITIONING A FILTERUSING FINE KCL PARTICLESTO DEMONSTRATEEFFICIENCY LOSSTHAT MIGHT BE REALIZED INFIELD APPLICATIONS.J11.3.3 With this appendix, the minimum efficiency report
