5、(ANS) is a national voluntary consensus standard developed under the auspices of ASHRAE. Consensus is definedby the American National Standards Institute (ANSI), of which ASHRAE is a member and which has approved this standard as an ANS, as “substantialagreement reached by directly and materially af
6、fected interest categories. This signifies the concurrence of more than a simple majority, but not necessarilyunanimity. Consensus requires that all views and objections be considered, and that an effort be made toward their resolution.” Compliance with thisstandard is voluntary until and unless a l
7、egal jurisdiction makes compliance mandatory through legislation.ASHRAE obtains consensus through participation of its national and international members, associated societies, and public review.ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing th
8、e Standard. The Project CommitteeChair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, all must be technicallyqualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all Project Committees. Th
9、e Manager of Standards of ASHRAE should be contacted for:a. interpretation of the contents of this Standard,b. participation in the next review of the Standard,c. offering constructive criticism for improving the Standard, ord. permission to reprint portions of the Standard.DISCLAIMERASHRAE uses its
10、 best efforts to promulgate Standards and Guidelines for the benefit of the public in light of available information and acceptedindustry practices. However, ASHRAE does not guarantee, certify, or assure the safety or performance of any products, components, or systems tested,installed, or operated
11、in accordance with ASHRAEs Standards or Guidelines or that any tests conducted under its Standards or Guidelines will benonhazardous or free from risk.ASHRAE INDUSTRIAL ADVERTISING POLICY ON STANDARDSASHRAE Standards and Guidelines are established to assist industry and the public by offering a unif
12、orm method of testing for rating purposes, bysuggesting safe practices in designing and installing equipment, by providing proper definitions of this equipment, and by providing other information thatmay serve to guide the industry. The creation of ASHRAE Standards and Guidelines is determined by th
13、e need for them, and conformance to them iscompletely voluntary.In referring to this Standard or Guideline and in marking of equipment and in advertising, no claim shall be made, either stated or implied, that theproduct has been approved by ASHRAE.ASHRAE STANDARDS COMMITTEE 20152016Douglass T.

19、 foreword is not part of this standard. It is merelyinformative and does not contain requirements necessaryfor conformance to the standard. 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 consensus pr
20、ocess. Unresolved objec-tors on informative material are not offered the right toappeal at ASHRAE or ANSI.)FOREWORDThe technical committee received a change request stating“The data set and the resulting composite curve are theactual data product of the test method, whereas the MERVclassification is
21、 merely a shortcut interpretation of the mini-mum efficiency composite curve. This reinforces this fact andstrengthens the committees position regarding the impor-tance of actual particle size efficiency rather than a nebulousquasi-rating classification.” The following changes requirethat the result
22、s of the efficiency calculations be required in thetest report.Note: In this addendum, changes to the current standardare indicated in the text by underlining (for additions) andstrikethrough (for deletions) unless the instructions specifi-cally mention some other means of indicating the changes. 11

27、d outdoor environment. ASHRAEs memberswill strive to minimize any possible deleterious effect on the indoor and outdoor environment of the systems and components in theirresponsibility while maximizing the beneficial effects these systems provide, consistent with accepted standards and the practical
28、 state ofthe art.ASHRAEs short-range goal is to ensure that the systems and components within its scope do not impact the indoor and outdoorenvironment to a greater extent than specified by the standards and guidelines as established by itself and other responsible bodies.As an ongoing goal, ASHRAE
29、will, through its Standards Committee and extensive technical committee structure, continue togenerate up-to-date standards and guidelines where appropriate and adopt, recommend, and promote those new and revised standardsdeveloped by other responsible organizations.Through its Handbook, appropriate
30、 chapters will contain up-to-date standards and design considerations as the material issystematically revised.ASHRAE will take the lead with respect to dissemination of environmental information of its primary interest and will seek out anddisseminate information from other responsible organization
31、s that is pertinent, as guides to updating standards and guidelines.The effects of the design and selection of equipment and systems will be considered within the scope of the systems intended useand expected misuse. The disposal of hazardous materials, if any, will also be considered.ASHRAEs primar
32、y concern for environmental impact will be at the site where equipment within ASHRAEs scope operates.However, energy source selection and the possible environmental impact due to the energy source and energy transportation will beconsidered where possible. Recommendations concerning energy source selection should be made by its members. ASHRAE (www.ashrae.org). For personal use only.
