SPECIAL NOTE

This American National Standard (ANS) is a national voluntary consensus Standard developed under the auspices of ASHRAE. Consensus is defined

by the American National Standards Institute (ANSI), of which ASHRAE is a member and which has approved this Standard as an ANS, as

“substantial agreement reached by directly and materially affected interest categories. This signifies the concurrence of more than a simple majority,

but not necessarily unanimity. Consensus requires that all views and objections be considered, and that an effort be made toward their resolution.”

Compliance with this Standard is voluntary until and unless a legal 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 the Standard. The Project

Committee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, all

must be technically qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all Project Committees.

The Senior 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, or

d. permission to reprint portions of the Standard.

DISCLAIMER

ASHRAE uses its best efforts to promulgate Standards and Guidelines for the benefit of the public in light of available information and accepted

industry practices. However, ASHRAE does not guarantee, certify, or assure the safety or performance of any products, components, or systems

tested, installed, or operated in accordance with ASHRAE’s Standards or Guidelines or that any tests conducted under its Standards or Guidelines

will be nonhazardous or free from risk.

ASHRAE INDUSTRIAL ADVERTISING POLICY ON STANDARDS

ASHRAE Standards and Guidelines are established to assist industry and the public by offering a uniform method of testing for rating purposes, by

suggesting safe practices in designing and installing equipment, by providing proper definitions of this equipment, and by providing other information

that may serve to guide the industry. The creation of ASHRAE Standards and Guidelines is determined by the need for them, and conformance

to them is completely 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 the product has been approved by ASHRAE.
