Thisignifesthe cncurrence ofmore thanasimple majority.Compliance with this Standard is voluntary untland unless a legal jurisdiction makes plance mandatory through legislation. but not necessarily unanimity. Consensus requires that all views and objections be considered and that an effort be made toward their resolution.*

ASHRAE obtains consensus through participation of its national and intemational members asociated societies and public review.

ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the Standrd. The ProjtCommittee Chair and Vice-Chair must be members of ASHRAE; while other mitte members may or may not be ASHRAE members all must be technicall qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on allProject Committees.

The Senior Manager of Standards of ASHRAE should be contacted for

First published in 2003 ASHRAE Standard 154 has been thoroughly revised in this ecdition to make it code enforceableOn mercial kitchen ventilation ponents and systems. and to provide the most plete design guidance availableupon recen laboratory research zhat was sponsored in part In revising this standard the project mifte has drawnby ASHRAE and assembled by the ASHRAE Technical Com-mittee on kitchen ventilation TC 5.10. It has also relied upon the significant field experiences of the manufacturers design-ers cnd users of kitchen ventilation systems. The standard iszation and ongoing revision of related model and adopted intended to serve as α template for standardization harmoni-codes cnd to bring consistency to design requirements cnd applications of mercial kitchen ventilation systems.

Ttis revision of Stcandard 154-2011addresses recentresearch CKV system ponents and cooking appliances advancements in mercial kitchen ventilation (CKV)and continues the acvancement of Standard 154 as the lead- ing CKV code-language design document.

The purpose of this standard is to provide design criteria foracceptable performance in mercial cooking ventilationsystems.
