a. The requirements for centrifugal chilling packages shall be adjusted for nonstandard rating conditions per Section 6.4.1.2.1 and are only applicable for the range of conditions listed

there. The requirements for air-cooled, liquid-cooled positive displacement and absorption chilling packages are at standard rating conditions defined in the reference test procedure. b. Both the full-load and IPLV .IP requirements must be met or exceeded to comply with this standard. When there is a Path B, compliance can be with either Path A or Path B for

any application. c. Section 13 contains a complete specification of the referenced test procedure, including the referenced year version of the test procedure. d. NA means the requirements are not applicable for Path B, and only Path A can be used for compliance. e. FL is the full-load performance requirements, and IPLV .IP is for the part-load performance requirements. f. Electrically operated chilling packages employing a freeze-protection liquid in accordance with Section 6.4.1.2.2 shall be tested or rated with water for the purpose of compliance

with the requirements of this table.
