Gives test procedures for determining the efficiency and hot-water delivery capability of the water-heating equipment to which it applies.

2.1 This standard provides test procedures for determining the efficiency and hot-water delivery capability of the waterheating equipment to which it applies.2.2 This standard applies to electric resistance, heat pump,gas-fired, and oil-fired water-heating equipment, including hot-water supply boilers, with input ratings less than 12,500,000 Btu/h (3660 kW) and greater than the following: Electric resistance 12 kW Heat pump 6 kW (20,500 Btu/h) (including all three-phase, regardless of input) Gas-fired 75,000 Btu/h (22 kW) (see Section 2.3) Oil-fired 105,000 Btu/h (31 kW) 2.3 This standard does not apply to gas-fired service waterheating equipment that a. has a storage capacity of less than two gallons,b. is designated to deliver water at a controlled temperature of less than 180°F (82°C), and c. has an input rating less than 200,000 Btu/h (59 kW).
