5 Attachment 1 Target Scope The criteria shall be applied to all microwave ovens. However, the followings shall be excluded from the scope: – Microwave ovens for business use The measurement method for household microwave ovens cannot be applied to microwave ovens for commercial use such as in convenience stores, restaurants, etc., because the number of use times is different between those for household use and for commercial use. Since not only the meas urement method for th e latter has not yet been established, but also the number is extremely small (fiscal year 2003: approximately 25,000 units), they shall be excluded from the scope. – Microwave ovens dedicated to rated input voltage of 200V They shall be excluded from the scope, because engineering works for 200V are necessary to use, because the usage is ge nerally different from those for household use, and because the number is extremely small (fiscal year 2003: approximately 10,000 units). – Microwave ovens of embedded type They are used in a built-in kitchen, and thus their adiabatic efficiency, etc. varies depending on design, materials, etc. of the built-in kitchen which they are embedded in. Because a meas urement method concerning such factors has not yet been established and because the number is extremely small (fiscal year 2003: approximately 23,000 units), they shall be excluded from the scope. – Microwave ovens having a gas oven They shall be excluded from the scope because gas ovens have already been designated as specified equipment of Top Runner Program. – Microwave ovens whose interior height of less than 135 mm Because measurement by using a tall beaker, which has been defined in the

7 Attachment 2 Target Fiscal Year, etc. for Microwave Ovens 1. In general, a considerable improvement in energy consumption efficiency of microwave ovens is made when a model change takes place, and a typical development period of these new products is approximately 1 year. For this reason, consideration should be given so that the manufacturers can take at least two opportunities of bringing out new models before the next target fiscal year. On the other hand, in light of measures against global warning, in order to ensure that products that achieved the target standard value become widely used among consumers during the first commitment period of Kyoto Protocol (2008 to 2012), it would be desirable to achieve the target in as short time as possible, assuming that the tenure of use of microwave ovens would be approximately 10 years. With the above in mind, the target year of microwave ovens shall be set to fiscal year 2008, three years after establishment of the criteria. 2. In addition, the improvement rate of energy consumption efficiency in the target fiscal year is expected to be approximatel y 8.5%, on the assumption that there will be no change from the current volume of shipments (results of fiscal year 2004) and composition by each category. (1)Energy consumption efficiency estimated from values of actual achievements of microwave ovens shipped in fiscal year 2004: 77.2 kWh/year (2)Energy consumption efficien cy estimated from target standard values of microwave ovens to be shipped in the targ et fiscal year: 70.6 kWh/year (3) Improvement rate of energy consumption efficiency 1002.776.702.77

8Attachment 3 Classification of Microwave Ovens 1. Basic Idea In the case of microwave ovens, function s, heating systems and inner volume have a large impact on energy consumption effici ency (annual energy consumption). Hence, microwave ovens shall be classified based on them. 2. Specific Classification Method (1) Classification by function Two types of microwave ovens exist; namely, microwave ovens that have oven function (oven-microwave oven) and that do not have oven function (single-function microwave oven). It is reasonable to classify them by the function because the difference influences energy consumption efficiency and development of energy saving technologies in the future. 1) Microwave ovens without oven function (single-function microwave oven) 2) Microwave ovens with oven function (oven-microwave oven) (2) Classification by heating method As for microwave ovens having oven function, they can be divided by heating method of oven function into the followings: those of direct heating method (those with an exposed heater inside of a microwave oven), those of radiation heating method (other than those with an exposed heater inside of a microwave oven), and those of hot air circulation heating method. Because the differences in the heating method s influence energy consumption efficiency, it would be reasonable to classify them by the heating method. In addition, for microwave ovens of hot air circulation heating method with a heater, as the heater is supplementary, they shall be classifi ed into the category of hot air circulation heating method, which is the main heating method (See Figure 1). 1) Microwave ovens with an exposed heater (excluding those of hot air circulation heating method) 2) Microwave ovens without an exposed heater (excluding those of hot air circulation heating method) 3) Microwave ovens of hot air circulation heating method

As the difference can influence energy consumption efficiency, it is reasonable to classify them into those having the inner volume of less than 30 L and those having the inner volume of 30L or greater (See Figure 2). fiInner volumefl refers to a numeric value computed from usable dimensions of a heating chamber defined by Electrical Machinery and Appliance Quality Labeling Regulations based on Household Goods Qu ality Labeling Law (Law No.104 of 1962). 1) Microwave ovens having the inner volume of less than 30L 2) Microwave ovens having the inner volume of 30L or greater Inner volume (L) Annual Energy Consumption [kWh/year] With an exposed heater Without an exposed heater Hot air circulation heating
