1. Scope
1.1 This Standard specifies the methods for determining seasonal energy utilization efficiency (SEUE) and annual fuel utilization efficiency (AFUE) for (a),,oil-fired furnaces having an input of up to and including 66 kW (225 000 Btu/h); and (b),,boilers having an input of up to and including 88 kW (300 000 Btu/h). The tests contained in this Standard are not intended to represent actual efficiencies realized in the field. These tests provide a standardized method of comparing relative unit performance.
1.2 This Standard establishes minimum efficiency levels for oil-fired furnaces and boilers.
1.3 This Standard applies to the oil-fired portion of a combination or multifuel burning appliance.
