For SI: 1 ton = 3517 W, 1 British thermal unit per hour =
				0.2931 W, °C = [(°F) - 32]/1.8.
NR = No requirement.
a Chapter 6 contains a complete
				specification of the referenced standards, which includes test procedures,
				including the referenced year version of the test procedure.
b The requirements for centrifugal
				chiller shall be adjusted for nonstandard rating conditions per Section
				C403.3.2.4 and are applicable only for the range of conditions listed there.
				The requirements for air-cooled, water-cooled positive displacement and
				absorption chillers are at standard rating conditions defined in the referenced
				test procedure.
c 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.
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.
