Significance and Use
5.1 The measured maximum energy input rate is used to confirm that the coffee brewer is operating in accordance with its nameplate rating.
5.2 If applicable and accessible, the boiler or internal tank temperature is measured to ensure that the water is maintained at a ready-to-brew temperature. This can also be used later to normalize coffee brewer energy consumption to a standard temperature.
5.3 The Preheat Test can be used to gauge the amount of time and energy required for the coffee brewer to reach a ready-to-brew state from the ambient room and incoming water temperatures.
5.4 Ready-to-Brew and Energy Save Mode energy can be used by end users to estimate the amount of energy consumed while coffee is not being brewed.
Scope
1.1 This test method covers the evaluation of the energy consumption, brewing, and holding performance of commercial coffee brewing machines (here after referred to as coffee brewers) used in commercial and institutional facilities. The operator can use this evaluation to select a coffee brewer and characterize its energy use and performance. This test method does not cover residential coffee brewers, “urn” coffee brewers (Type III), or espresso machines.
1.2 This test method applies to single cup (Type I) and batch (Type II) coffee brewers. The coffee brewer will be tested for the following (where applicable):
