### 2 **9:00 a.m.** 

### 3 **MR. BROOKMAN: Good morning,** 

### 4 **everyone, and welcome.** 

### 5 **This is the U.S. Department of** 

### 6 **Energy's public meeting on test procedures for** 

### 7 **microwave ovens. Today is March 5th, 2013,** 

### 8 **here at the Forrestal Building in Washington,** 

### 9 **D.C.** 

### 10 **My name is Doug Brookman from** 

### 11 **Public Solutions in Baltimore.** 

### 12 **I am so glad you could join us** 

### 13 **this morning.** 

### 14 **We are going to start off this** 

### 15 **morning with welcoming remarks from Ashley.** 

### 16 **MS. ARMSTRONG: Hi. My name is** 

### 17 **Ashley Armstrong with DOE.** 

### 18 **I welcome you guys to what is,** 

### 19 **hopefully, going to be a pretty short public** 

### 20 **meeting today on microwave ovens and the** 

### 21 **active mode test procedure.** 

### 22 **We are going to go through some of**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 4**  **1 the stuff pretty quickly. Most of our test**  

### 2 **data is in the Notice or in the back.** 

### 3 **If you have questions, feel free** 

### 4 **to speak up throughout the presentation. We** 

### 5 **are happy to engage. And, yes, we look** 

### 6 **forward to the dialog.** 

### 7 **Thanks.** 

### 8 **MR. BROOKMAN: Thank you.** 

### 9 **Let's start with introductions, as** 

### 10 **we typically do. I will start to my immediate** 

### 11 **left, and you can get used to turning the** 

### 12 **microphones on and off. Your name and** 

### 13 **organizational affiliation, please.** 

### 14 **MR. SHARP: Mark Sharp with** 

### 15 **Panasonic.** 

### 16 **MR. YAMAUCHI: Masa Yamauchi from** 

### 17 **Panasonic.** 

### 18 **MS. CLEARY: Jennifer Cleary with** 

### 19 **the Association of Home Appliance** 

### 20 **Manufacturers.** 

### 21 **MS. MAUER: Joanna Mauer,**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 5**  **1 MS. REICH: Judith Reich,**  

### 2 **Navigant.** 

### 3 **MR. BATTAGLIA: James Battaglia,** 

### 4 **Navigant.** 

### 5 **MR. ALTMAN: Ari Altman with DOE,** 

### 6 **GC's Office.** 

### 7 **MR. BROOKMAN: We will go next to** 

### 8 **you.** 

### 9 **MS. REIS: Oh, sorry. Callie** 

### 10 **Reis, Navigant.** 

### 11 **MR. BROOKMAN: Okay, and I guess** 

### 12 **that is all of us.** 

### 13 **All of you received a packet of** 

### 14 **information as you entered the room this** 

### 15 **morning.** 

### 16 **I will do a very brief agenda** 

### 17 **review. After this agenda review, there is an** 

### 18 **opportunity for anyone that wishes to do so to** 

### 19 **make brief summary remarks about issues that** 

### 20 **are of importance to you. And following that,** 

### 21 **we will have an introduction in regulatory** 

### 22 **history. And then, immediately following**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 6**  **1 that, covered products consumer usage, moving**  

### 2 **on to test methods and microwave-only ovens.** 

### 3 **We will take a break mid-morning** 

### 4 **round about 10:45, or as needed. And then,** 

### 5 **following that, test methods for convection** 

### 6 **only microwave ovens, measures of energy** 

### 7 **consumption compliance with other EPCA** 

### 8 **requirements.** 

### 9 **And then, at the end of the day,** 

### 10 **whenever we get there today, an opportunity** 

### 11 **again for closing remarks; that is, other** 

### 12 **issues that we haven't covered sufficiently** 

### 13 **for your needs here.** 

### 14 **And we will adjourn following** 

### 15 **those closing remarks and a review of how you** 

### 16 **submit your comments.** 

### 17 **Questions and comments about the** 

### 18 **agenda?** 

### 19 **(No response.)** 

### 20 **Seeing none, I would ask for your** 

### 21 **consideration. Please speak one at a time** 

### 22 **today, and say your name for the record each**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 7**  **1 time you speak.**  

### 2 **There will be a complete** 

### 3 **transcript of this meeting.** 

### 4 **If you could keep the focus here,** 

### 5 **limit your sidebar conversations, and turn** 

### 6 **your cell phones on silent.** 

### 7 **I am told we have some individuals** 

### 8 **joining us via the web. Yes? How many? Just** 

### 9 **two. Welcome.** 

### 10 **The Department is trying to make** 

### 11 **these meetings accessible to everyone via the** 

### 12 **web. Those of you joining by the web, if you** 

### 13 **would keep your telephones on mute, and you** 

### 14 **can raise your hand if you wish to join this** 

### 15 **conversation, and we will get you in the** 

### 16 **conversation as soon as possible.** 

### 17 **So, I think that is all the** 

### 18 **preliminary stuff.** 

### 19 **Who is going to start off? James** 

### 20 **is going to start it off? James Battaglia.** 

### 21 **All of you received a packet of** 

### 22 **information. These PowerPoint slides will be**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 8**  **1 the basis for both presentation and queuing**  

### 2 **discussion and comment.** 

### 3 **MR. BATTAGLIA: Okay. Hi,** 

### 4 **everybody. I am James Battaglia.** 

### 5 **Just to quickly give some** 

### 6 **background information, the NOPR published on** 

### 7 **February 4th, and I think the other key date** 

### 8 **here is the date for the comments, the written** 

### 9 **comments, is April 22nd.** 

### 10 **And just some quick background,** 

### 11 **unless there are any questions on any of this,** 

### 12 **the test procedure was originally established** 

### 13 **in a final rule in 1997. That incorporated by** 

### 14 **reference IEC 705. That test procedure was** 

### 15 **later repealed in the final rule in July of** 

### 16 **2010, and DOE determined in that rule that the** 

### 17 **microwave oven active mode test procedure did** 

### 18 **not produce representative and repeatable test** 

### 19 **results.** 

### 20 **DOE held a public meeting in July** 

### 21 **of 2010 to initiate a new rulemaking process** 

### 22 **to address active mode, and we also published**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 9**  **1 a Request for Information notice in October of**  

### 2 **2011 to request information and comments on** 

### 3 **representative and repeatable methods for** 

### 4 **microwave active mode.** 

### 5 **And DOE also published in June of** 

### 6 **2012 a NODA to present test results and** 

### 7 **approaches that it was considering for** 

### 8 **potential amendments for microwave oven active** 

### 9 **mode, considering the different cooking modes** 

### 10 **for microwave-only, convection-only, and** 

### 11 **convection-microwave cooking.** 

### 12 **So, now just to discuss the** 

### 13 **products that are covered by this rulemaking,** 

### 14 **the proposed amendments will be applicable to** 

### 15 **microwave ovens which are defined in DOE's** 

### 16 **regulations as a class of kitchen ranges and** 

### 17 **ovens that consist of a compartment designed** 

### 18 **to cook or heat food by means of microwave** 

### 19 **energy, and that includes microwaves with or** 

### 20 **without thermal elements designed for surface** 

### 21 **browning and, also, convection microwave** 

### 22 **ovens.**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 10**  **1 And DOE determined that ovens**  

### 2 **equipped with microwave capability, including** 

### 3 **convection microwave ovens, are covered under** 

### 4 **that definition. And DOE adopted a definition** 

### 5 **of convection microwave ovens in a January** 

### 6 **2013 test procedure final rule that addressed** 

### 7 **standby and off mode for microwave ovens, and** 

### 8 **DOE defined convection microwave ovens as** 

### 9 **microwave ovens that incorporate microwave** 

### 10 **capability, convection features, and any other** 

### 11 **cooking means in a single compartment.** 

### 12 **DOE has also determined that all** 

### 13 **products that combine a microwave with any** 

### 14 **other appliance functionality would also be** 

### 15 **considered covered products. And that** 

### 16 **includes products such as a** 

### 17 **microwave/conventional range or** 

### 18 **microwave/conventional oven, a** 

### 19 **microwave/conventional cooking top, or other** 

### 20 **combined products such as a microwave plus a** 

### 21 **refrigerator.** 

### 22 **However, DOE is not proposing to**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 11**  **1 require that such combined products be tested**  

### 2 **according to the proposed amendments that we** 

### 3 **will be discussing today. That is because of** 

### 4 **a lack of information regarding appropriate** 

### 5 **testing methods and proper apportionment of** 

### 6 **the energy use between the different** 

### 7 **functional components of the combined** 

### 8 **products.** 

### 9 **So, as part of developing the test** 

### 10 **procedure amendments, DOE considered available** 

### 11 **consumer usage data, and DOE noted that** 

### 12 **Lawrence Berkeley National Labs conducted a** 

### 13 **consumer usage survey to evaluate the consumer** 

### 14 **usage habits for microwave ovens. That survey** 

### 15 **collected data for microwave-only oven users,** 

### 16 **and that was for over 2200 households, and,** 

### 17 **also, over 650 households that had convection** 

### 18 **microwave oven users.** 

### 19 **And you can see the data from that** 

### 20 **study here. You can see that the microwave** 

### 21 **only cooking mode was used the most** 

### 22 **frequently. However, you can see that for the**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 12**  **1 convection-only and convection-microwave**  

### 2 **cooking modes, those have significantly longer** 

### 3 **cycle times than the microwave-only cycle.** 

### 4 **So, now getting into the test** 

### 5 **methods that we will be discussing for the** 

### 6 **microwave-only ovens, before being repealed,** 

### 7 **DOE's previous test procedure for microwave** 

### 8 **ovens incorporated by reference IEC 705, which** 

### 9 **was the IEC procedure for microwave active** 

### 10 **mode cooking. And that procedure measured the** 

### 11 **amount of energy needed to heat 1 kilogram of** 

### 12 **water by 10 degrees Celsius. And the test** 

### 13 **procedure also provided a calculation for the** 

### 14 **EF, which is a measure of cooking efficiency,** 

### 15 **as the ratio of the usable output power over** 

### 16 **the input power.** 

### 17 **IEC published an updated version** 

### 18 **which was redesignated as 60705, and the** 

### 19 **latest published version is the fourth** 

### 20 **edition, which was published in April of 2010.** 

### 21 **However, that procedure used the same basic** 

### 22 **test methods that the IEC 705 used.**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 13**  **1 DOE also noted that the IEC is in**  

### 2 **the process of revising its current test** 

### 3 **standard for microwave ovens, and then, the** 

### 4 **latest draft version that DOE was aware of was** 

### 5 **the November 2011 draft version.** 

### 6 **Now that November 2011 draft** 

### 7 **version included a new test method that** 

### 8 **continued to use water as the cooking load.** 

### 9 **So, that draft test method measured the energy** 

### 10 **consumption needed to heat three different** 

### 11 **load sizes, so the 275-gram, 350-gram, and** 

### 12 **1,000-gram water loads in different size test** 

### 13 **containers, first, by 45 to 50 degrees** 

### 14 **Celsius, and then, a separate test heating the** 

### 15 **load by 50 to 55 degrees Celsius.** 

### 16 **And the results from each load** 

### 17 **size were then used to interpolate the energy** 

### 18 **consumption needed to heat the load by exactly** 

### 19 **50 degrees. The cooking cycle energy** 

### 20 **consumption for each load size was then** 

### 21 **weighted based on consumer use, based on the** 

### 22 **factors in the IEC procedure, to calculate an**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 14**  **1 average weighted per-cycle energy consumption.**  

### 2 **The draft IEC method also included** 

### 3 **a method for measuring the cooling-down energy** 

### 4 **consumption after the completion of a 50-** 

### 5 **degrees C temperature rise test. That** 

### 6 **procedure measured the energy use at the end** 

### 7 **of the cycle for a fixed period of 15 minutes.** 

### 8 **Now, although this procedure could** 

### 9 **be used to measure all microwave ovens,** 

### 10 **including those that just revert back to** 

### 11 **standby or off mode after the cooking cycle,** 

### 12 **the IEC procedure noted that this procedure** 

### 13 **was designed to measure the energy consumption** 

### 14 **associated with ventilating the microwave** 

### 15 **oven, which is to say operating a fan to cool** 

### 16 **down the cavity. And that draft method** 

### 17 **included this as an informative annex that was** 

### 18 **not required to be conducted.** 

### 19 **Now in the June 2012 NODA, DOE** 

### 20 **presented its testing results from testing the** 

### 21 **data according to the draft IEC method. And** 

### 22 **you can see here the average-per-cycle energy**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 15**  **1 consumption ranged from about 38 to about 115**  

### 2 **watt-hours per cycle, and the test-to-test** 

### 3 **variation was about half a percent to about 1** 

### 4 **percent.** 

### 5 **And DOE also conducted testing to** 

### 6 **evaluate the cooling-down test method after** 

### 7 **the completion of the microwave-only cycle.** 

### 8 **And again, test results showed minimal** 

### 9 **variation in the measured cooling-down energy** 

### 10 **consumption. And for all the units that DOE** 

### 11 **tested, none actually contained a fan that** 

### 12 **operated at the end of the microwave-only** 

### 13 **cooking cycle. And when the door was closed,** 

### 14 **the products all reverted back to standby** 

### 15 **mode.** 

### 16 **DOE also noted that the European** 

### 17 **Committee for Electrotechnical** 

### 18 **Standardization, which is known as CENELEC,** 

### 19 **they also conducted a round-robin testing** 

### 20 **program to evaluate the draft test method.** 

### 21 **That consisted of five manufacturer test labs** 

### 22 **and five independent test labs using four**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 16**  **1 different microwave oven models. And based on**  

### 2 **that testing, the results shown in the table,** 

### 3 **CENELEC determined that the repeatability and** 

### 4 **reproducibility for that draft test method** 

### 5 **were deemed to be acceptable.** 

### 6 **So, based on DOE and CENELEC** 

### 7 **testing, DOE believes that the test methods in** 

### 8 **the November 2011 draft IEC 60705 produced** 

### 9 **repeatable and reproducible results. So, DOE** 

### 10 **is proposing to include provisions for** 

### 11 **measuring the microwave-only active mode** 

### 12 **energy consumption based on that draft test** 

### 13 **method. And we are also proposing some** 

### 14 **additional language to clarify those** 

### 15 **provisions that we will get into in the next** 

### 16 **few slides.** 

### 17 **So, first, for the definitions,** 

### 18 **the current DOE test procedure includes** 

### 19 **definitions of built-in and freestanding, but** 

### 20 **DOE is proposing to also add a definition for** 

### 21 **over-the-range to describe the installation** 

### 22 **configuration for certain microwaves that are**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 17**  **1 intended to be installed in the cabinetry**  

### 2 **above the conventional cooking top or range.** 

### 3 **And DOE is also proposing to include in that** 

### 4 **definition that such products are supported by** 

### 5 **the cabinetry walls or other similar** 

### 6 **structures on the sides, top, and/or rear of** 

### 7 **the product.** 

### 8 **Again, for over-the-range** 

### 9 **microwave ovens, those products are generally** 

### 10 **equipped with a fan that is designed to vent** 

### 11 **air out of the cooking cavity. And those** 

### 12 **offer two different installation** 

### 13 **configurations.** 

### 14 **The first is such that the vent** 

### 15 **exhausts air from the cooking cavity to the** 

### 16 **outdoors, and the second is such that the vent** 

### 17 **recirculates air back into the room. Now DOE** 

### 18 **is proposing to require that over-the-range** 

### 19 **ovens be installed with the exhaust vent** 

### 20 **recirculation fan installed in the** 

### 21 **recirculation configuration, and this was** 

### 22 **based on DOE's review of the products in its**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 18**  **1 test sample, that this was generally the**  

### 2 **default configuration for most products that** 

### 3 **we had in our sample, and it will also** 

### 4 **minimize burden by not requiring additional** 

### 5 **requirements for the test room to be capable** 

### 6 **of venting outdoors. So, DOE is proposing** 

### 7 **this to provide a consistent method across all** 

### 8 **different products.** 

### 9 **Now, for the setup of testing, the** 

### 10 **November 2011 draft IEC 60705 specifies that** 

### 11 **at the beginning of the test the oven shall** 

### 12 **not have been operated for a period of at** 

### 13 **least six hours before each test. The draft** 

### 14 **test method also specifies that the** 

### 15 **temperature of the magnetron and the power** 

### 16 **supply must be within 2 degrees Celsius of the** 

### 17 **ambient temperature and that forced air may be** 

### 18 **used to cool the microwave oven to the ambient** 

### 19 **conditions.** 

### 20 **Currently, the DOE test procedure** 

### 21 **specifies for testing that all areas of the** 

### 22 **appliance shall attain what is called the**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 19**  **1 normal non-operating temperature before any**  

### 2 **tests. And that is defined in the test** 

### 3 **procedure as the temperature that the** 

### 4 **appliance would achieve if it remained in the** 

### 5 **test room for 24 hours, plus or minus 2.8** 

### 6 **degrees Celsius.** 

### 7 **And DOE is not proposing to amend** 

### 8 **that definition of the normal non-operating** 

### 9 **temperature currently specified in the DOE** 

### 10 **test procedure. Now we recognize that it is a** 

### 11 **slightly larger range. However, DOE noted** 

### 12 **that both of these methods essentially specify** 

### 13 **that the product be at the ambient condition.** 

### 14 **So, DOE wasn't aware that the change in the** 

### 15 **temperature range would have an effect, a** 

### 16 **measurable effect, on the efficiency.** 

### 17 **Now the November 2011 draft test** 

### 18 **method also specifies, when making temperature** 

### 19 **measurements, that the water loads be placed** 

### 20 **on a thermally-insulating pad. DOE is just** 

### 21 **proposing an additional clarification to** 

### 22 **require that the pad have a heat capacity of**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 20**  **1 1.3 kilojoules per kilogram kelvin or less,**  

### 2 **which is the heat capacity of polystyrene,** 

### 3 **which is a readily-available material that** 

### 4 **will effectively insulate the water load in** 

### 5 **making those temperature measurements.** 

### 6 **Jenn?** 

### 7 **MS. CLEARY: Jennifer Cleary.** 

### 8 **I just have a question, and it is** 

### 9 **just sort of related to the setup, but not to** 

### 10 **something you presented.** 

### 11 **MR. BATTAGLIA: Okay.** 

### 12 **MS. CLEARY: In Section 2.9.3.1,** 

### 13 **it indicates that the test room temperature** 

### 14 **indicating system shall have a minimum** 

### 15 **resolution of 0.18 degrees Fahrenheit or 0.1** 

### 16 **degrees Celsius and a max error no greater** 

### 17 **than those things, 0.18 degrees Fahrenheit and** 

### 18 **0.1 degrees Celsius. We are just wondering if** 

### 19 **that is an error because the IEC max error is** 

### 20 **1 degrees Celsius.** 

### 21 **MR. BATTAGLIA: That may be. We** 

### 22 **will take a look at it. We should be using**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 21**  **1 those same parameters for the temperature**  

### 2 **measurement. So, we will take a look at that.** 

### 3 **MS. CLEARY: Okay. Yes, it just** 

### 4 **seemed like a pretty big difference.** 

### 5 **MR. BATTAGLIA: Yes, yes. Okay.** 

### 6 **Thank you.** 

### 7 **All right. So, DOE is proposing** 

### 8 **to include test methods for measuring the** 

### 9 **energy consumption of the fan-only mode while** 

### 10 **the microwave is cooling down after the end of** 

### 11 **the microwave-only active mode cycle.** 

### 12 **As we discussed, none of the** 

### 13 **products in DOE's test sample were actually** 

### 14 **equipped with a fan that operated at the end** 

### 15 **of the microwave-only cooking cycle, but,** 

### 16 **instead, just reverted back to standby and off** 

### 17 **mode when the load was removed and the door is** 

### 18 **closed. However, DOE recognizes that products** 

### 19 **could be made available that do have a fan** 

### 20 **that operated in that fan-only mode after the** 

### 21 **end of the cycle.** 

### 22 **So, we are proposing that the fan-**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 22**  **1 only mode be measured for only those products**  

### 2 **equipped with a fan that operates at the end** 

### 3 **of the microwave-only active mode cycle. So,** 

### 4 **we are proposing to add a definition of fan** 

### 5 **only mode as a mode that is not user** 

### 6 **selectable and in which a fan circulates air** 

### 7 **internally or externally to the microwave oven** 

### 8 **for a finite period of time after the end of** 

### 9 **the cooking cycle.** 

### 10 **So, for products that are capable** 

### 11 **of operating in fan-only mode, DOE is** 

### 12 **proposing that the fan-only mode be measured** 

### 13 **based on the provisions in the November 2011** 

### 14 **draft IEC 60705 with an additional** 

### 15 **modification that, instead of being measured** 

### 16 **for a fixed period of 15 minutes, the energy** 

### 17 **consumption and duration of the fan-only mode** 

### 18 **would be measured just until the end of that** 

### 19 **fan-only mode.** 

### 20 **Now DOE is not aware of the** 

### 21 **typical duration of fan-only mode since none** 

### 22 **of the products in its test sample were**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 23**  **1 capable of such a mode. Now we noted that the**  

### 2 **November 2011 draft test method specifies that** 

### 3 **the load should be removed and the door closed** 

### 4 **within 30 seconds after the 50-degrees C** 

### 5 **temperature rise when making that fan-only** 

### 6 **mode measurement. And as you will see in a** 

### 7 **few slides, we are requesting comment on** 

### 8 **whether that 30-second period will** 

### 9 **sufficiently capture the fan-only mode energy** 

### 10 **consumption. That is just for the door being** 

### 11 **closed, so whether the duration of the fan** 

### 12 **only mode is such that the 30 seconds won't** 

### 13 **affect the fan-only mode energy consumption.** 

### 14 **Now the draft IEC test method does** 

### 15 **not require multiple repeat test runs.** 

### 16 **However, DOE believes that requiring multiple** 

### 17 **runs will improve the accuracy of test** 

### 18 **results. So, we are proposing to require that** 

### 19 **the full microwave-only test be repeated three** 

### 20 **times unless the total per-cycle energy** 

### 21 **consumption for the second measurement is** 

### 22 **within 1.5 percent of the value from the first**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 24**  **1 measurement.**  

### 2 **So, here we have our first comment** 

### 3 **request, and that is for the proposed methods** 

### 4 **for measuring the active mode energy use,** 

### 5 **based on the provisions in the IEC, draft IEC** 

### 6 **test method. And we are also seeking comments** 

### 7 **on the number of repeat test runs.** 

### 8 **Jennifer?** 

### 9 **MS. CLEARY: Jennifer Cleary.** 

### 10 **I have a few questions. First,** 

### 11 **just regarding the testing, do you recall what** 

### 12 **the age of the products that were tested? I** 

### 13 **know it was for the notice, so it was a while** 

### 14 **ago. But do you know what age those products** 

### 15 **were?** 

### 16 **MR. BATTAGLIA: We would have to** 

### 17 **go back and look to see exactly what those** 

### 18 **were.** 

### 19 **MS. CLEARY: And did DOE take a** 

### 20 **look at what percentage of the market, like in** 

### 21 **terms of shipments, the test sample** 

### 22 **represents?**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 25**  **1 MR. BATTAGLIA: I don't know that**  

### 2 **we have specific data on specific model of** 

### 3 **shipments.** 

### 4 **MS. ARMSTRONG: Yes. Well, I** 

### 5 **would just say, typically, we picked units** 

### 6 **that were typical of those that were high** 

### 7 **shipments, but I don't think that we did** 

### 8 **specific shipments. But I think you could say** 

### 9 **they are pretty representative --** 

### 10 **MR. BATTAGLIA: Yes, we tried** 

### 11 **to --** 

### 12 **MS. ARMSTRONG: -- of typical** 

### 13 **microwaves on the market.** 

### 14 **MR. BATTAGLIA: Yes. In the NOPR,** 

### 15 **you can see we try to capture a wider range of** 

### 16 **product, the cavity volumes and power ratings.** 

### 17 **MS. CLEARY: And then, my final** 

### 18 **question is regarding the three test runs. I** 

### 19 **guess it is a little unclear why DOE is** 

### 20 **deciding to go with three when IEC determined** 

### 21 **that the repeatability and reproducibility was** 

### 22 **acceptable and is requiring only one test run.**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 26**  **1 So, I am just wondering a little bit about**  

### 2 **what additional data DOE might have that is** 

### 3 **requiring three and how it is determined that** 

### 4 **three is the appropriate number as well.** 

### 5 **MR. BATTAGLIA: That provision is** 

### 6 **based on the previous IEC 705. We are** 

### 7 **certainly open to comments on whether that** 

### 8 **number is required or is necessary to** 

### 9 **accurately represent the results.** 

### 10 **MS. CLEARY: Thank you.** 

### 11 **MR. BROOKMAN: Thank you.** 

### 12 **Additional comments based on this** 

### 13 **comment box?** 

### 14 **(No response.)** 

### 15 **Okay.** 

### 16 **MR. BATTAGLIA: Okay, and the next** 

### 17 **topic we are seeking comment on is the fan** 

### 18 **only mode proposal and the proposal to only** 

### 19 **measure it for those products that are capable** 

### 20 **of operating in fan-only mode.** 

### 21 **We are also seeking comment on** 

### 22 **whether the 30-second period to remove the**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 27**  **1 test load from the microwave and close the**  

### 2 **door would accurately measure the microwave** 

### 3 **only fan-only mode energy use.** 

### 4 **MR. BROOKMAN: Jen?** 

### 5 **MS. CLEARY: Jennifer Cleary** 

### 6 **again.** 

### 7 **I gather, since I didn't see any** 

### 8 **data, that DOE hasn't done any additional** 

### 9 **testing since the NODA?** 

### 10 **MR. BATTAGLIA: No. No, anything** 

### 11 **that is in the NOPR, I believe it just** 

### 12 **presents the results from the NODA.** 

### 13 **MS. CLEARY: Okay. So, then, I** 

### 14 **guess, based on that, then, DOE has not done** 

### 15 **any testing on the proposal as it is proposed** 

### 16 **in the NOPR?** 

### 17 **MR. BATTAGLIA: Well, for fan-only** 

### 18 **mode, we didn't have any products that** 

### 19 **operated in fan-only mode. So, based on this** 

### 20 **proposal, that was --** 

### 21 **MS. ARMSTRONG: That is correct.** 

### 22 **MR. BATTAGLIA: Yes.**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 28**  **1 MR. BROOKMAN: Thank you, Ashley.**  

### 2 **MS. CLEARY: Thank you.** 

### 3 **MR. BATTAGLIA: Okay. One last** 

### 4 **topic for microwave-only ovens. Just that in** 

### 5 **the NODA, DOE presented results from testing** 

### 6 **to evaluate mixtures that would simulate food** 

### 7 **loads that are heated in the microwave. And** 

### 8 **those mixtures were composed of water and** 

### 9 **basic food ingredients with a total combined** 

### 10 **mass of 350 grams. Those ingredients** 

### 11 **composing each mixture were based on** 

### 12 **nutritional labels of commonly-microwaved** 

### 13 **foods.** 

### 14 **And DOE also conducted some** 

### 15 **additional testing with just one or two key** 

### 16 **ingredients to see whether that would improve** 

### 17 **the repeatability of results. However, the** 

### 18 **test results that we presented in the NODA** 

### 19 **showed a higher range in average test** 

### 20 **variation compared to the water-only tests.** 

### 21 **So, DOE is not proposing to require the use of** 

### 22 **real or simulated foods for microwave-only**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 29**  **1 mode.**  

### 2 **Okay. Now getting into the test** 

### 3 **methods for convection microwave ovens,** 

### 4 **convection microwave ovens typically can be** 

### 5 **operated using different cooking modes. So,** 

### 6 **the microwave-only cooking mode, the** 

### 7 **convection-only, and the convection microwave** 

### 8 **mode.** 

### 9 **DOE noted that convection** 

### 10 **microwave ovens represent a significant number** 

### 11 **of shipments and warrant separate testing** 

### 12 **methods. And DOE noted that convection** 

### 13 **microwave ovens represent about 4 percent of** 

### 14 **microwave shipments, and that equates to about** 

### 15 **400,000 annual shipments.** 

### 16 **And based on DOE's testing that we** 

### 17 **will present a little later, the convection** 

### 18 **only cooking mode represents about 28 percent** 

### 19 **of the total annual energy consumption and the** 

### 20 **convection microwave cooking mode represents** 

### 21 **about 17 percent.** 

### 22 **So, for convection microwave**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 30**  **1 ovens, for the microwave-only mode, DOE is**  

### 2 **proposing to use the same basic test method** 

### 3 **that we described in the last section for** 

### 4 **measuring the microwave-only mode. That is** 

### 5 **based on the November 2011 draft, IEC 60705.** 

### 6 **We are just seeking comment on that** 

### 7 **specifically for convection microwave ovens** 

### 8 **here.** 

### 9 **Okay. For the June 2012 NODA, DOE** 

### 10 **investigated whether a test procedure could be** 

### 11 **developed to measure the convection-only** 

### 12 **cooking mode for convection microwave ovens.** 

### 13 **And for the June 2012 NODA, DOE developed a** 

### 14 **test method based on the DOE conventional oven** 

### 15 **test procedure.** 

### 16 **That procedure first requires that** 

### 17 **you set the temperature controls for the** 

### 18 **convection cooking cycle, so that the** 

### 19 **temperature inside the cavity is 325 degrees** 

### 20 **Fahrenheit higher than the room ambient** 

### 21 **temperature. Then, the test requires that you** 

### 22 **heat an 8.5-pound cylindrical aluminum test**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 31**  **1 block from the ambient temperature until the**  

### 2 **test block temperature has increased by 234** 

### 3 **degrees Fahrenheit above its initial** 

### 4 **temperature. And the measured energy** 

### 5 **consumption from the cycle is, then, used to** 

### 6 **measure the cooking efficiency and the energy** 

### 7 **factor.** 

### 8 **Now DOE noted that the cavity** 

### 9 **temperature requirement of 325 degrees** 

### 10 **Fahrenheit higher than the room ambient** 

### 11 **temperature would result in a temperature** 

### 12 **setting close to 400 degrees Fahrenheit. Now,** 

### 13 **based on DOE's review of products on the** 

### 14 **market, a number of convection microwave ovens** 

### 15 **do not have a 400-degree Fahrenheit** 

### 16 **temperature setting, but all the products that** 

### 17 **DOE surveyed had a 375-degree setting.** 

### 18 **As a result, DOE modified the test** 

### 19 **method for the NODA to conduct the testing** 

### 20 **using the 375-degree temperature setting,** 

### 21 **again, to heat the aluminum block to 234** 

### 22 **degrees above the initial temperature. And**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 32**  **1 DOE also specified for the testing that the**  

### 2 **aluminum test block be placed on the metal** 

### 3 **cooking rack that is provided with the product** 

### 4 **by the manufacturer.** 

### 5 **So, here we just have the results** 

### 6 **from testing. And you can see, for this** 

### 7 **method, it showed minimal test-to-test** 

### 8 **variation. And that was about 1.3 percent on** 

### 9 **average.** 

### 10 **So, based on the testing analysis,** 

### 11 **DOE is proposing to amend the cooking test** 

### 12 **procedure to measure the convection-only** 

### 13 **cooking mode, based on the test method that we** 

### 14 **described previously, along with some** 

### 15 **additional clarifications.** 

### 16 **Specifically for the turntable,** 

### 17 **DOE is proposing to require that, if the** 

### 18 **product allows for that turntable to be turned** 

### 19 **on or off, it shall be tested with the** 

### 20 **turntable turned on. And this is because DOE** 

### 21 **noted that the turntable is typically turned** 

### 22 **on by default. So, as a result, that would be**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 33**  **1 likely the most common configuration used by**  

### 2 **consumers.** 

### 3 **Now, for fan-only mode, DOE again** 

### 4 **is proposing to require that the energy use** 

### 5 **and duration of that mode be measured until** 

### 6 **the end of the fan-only mode at the end of the** 

### 7 **convection-only cooking cycle. And again,** 

### 8 **this was based on different durations of the** 

### 9 **mode. So, DOE noted in its testing that the** 

### 10 **fan-only mode duration was between zero and** 

### 11 **seven minutes. DOE also believes that the** 

### 12 **added test time for the fan-only mode will be** 

### 13 **minimal compared to the overall convection** 

### 14 **only test cycling.** 

### 15 **So, DOE is also proposing to add** 

### 16 **new sections to calculate the convection** 

### 17 **microwave oven convection-only cooking cycle** 

### 18 **energy consumption, using the same basic** 

### 19 **calculations that are currently in the DOE** 

### 20 **conventional oven test procedure. Now the** 

### 21 **convection-only cooking cycle and fan-only** 

### 22 **mode energy consumption would be added**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 34**  **1 together to calculate the convection-only mode**  

### 2 **energy consumption. And DOE is also proposing** 

### 3 **to apply a field-use factor to the convection** 

### 4 **only mode energy consumption to account for** 

### 5 **the typical consumer use of this mode, using** 

### 6 **the data that we presented earlier.** 

### 7 **So, DOE determined that field-use** 

### 8 **factor is 0.26, based on the average** 

### 9 **convection-only cooking cycle length, based on** 

### 10 **the consumer use data, which was 18.7 minutes** 

### 11 **divided by the average measured test cycle** 

### 12 **length for units in DOE's test cycle, which** 

### 13 **was about 73 minutes.** 

### 14 **And again, here DOE is again** 

### 15 **proposing to require that the test be repeated** 

### 16 **three times, unless the second measurement is** 

### 17 **within 1.5 percent of the value obtained for** 

### 18 **the first measurement. And again, that is to** 

### 19 **improve the accuracy of the test results.** 

### 20 **So, here we are seeking comments** 

### 21 **on the proposed convection-only mode test** 

### 22 **method that is based on the DOE convection**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 35**  **1 test procedure. And we are also seeking**  

### 2 **comment, again, on the requirement to repeat** 

### 3 **the test runs.** 

### 4 **MR. BROOKMAN: Jennifer?** 

### 5 **MS. CLEARY: Jennifer Cleary.** 

### 6 **Again, I have a number of** 

### 7 **questions. I'm sorry.** 

### 8 **MR. BROOKMAN: That is okay.** 

### 9 **MS. CLEARY: First, I was just** 

### 10 **wondering if DOE considered any safety issues** 

### 11 **that might be associated with testing** 

### 12 **convection? Or did you encounter any while** 

### 13 **you were doing investigative testing?** 

### 14 **MR. BATTAGLIA: For the** 

### 15 **convection-only ovens, DOE did not observe any** 

### 16 **safety issues. It was essentially the same** 

### 17 **procedure as convection ovens. So, it is not** 

### 18 **using the microwave function during that** 

### 19 **convection-only test.** 

### 20 **MS. CLEARY: Since the turntable,** 

### 21 **if there is a turntable and it can be turned** 

### 22 **off or on, will be turned on, can DOE clarify**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 36**  **1 where it is thinking the thermocouple junction**  

### 2 **would be?** 

### 3 **MR. BATTAGLIA: So, the** 

### 4 **thermocouple junction, there is still a hole** 

### 5 **in the test block, so that the thermocouple is** 

### 6 **inserted inside the test block. We don't have** 

### 7 **any issues, if the test load is placed at the** 

### 8 **center of the turntable, we didn't have any** 

### 9 **issues with the contact or anything like that.** 

### 10 **So, I don't think there were any issues with** 

### 11 **that, that we experienced at least.** 

### 12 **MS. CLEARY: Okay. Thank you.** 

### 13 **And my last set of questions. I** 

### 14 **guess DOE is proposing to use the same test** 

### 15 **block as is currently used in the convection** 

### 16 **cooking product test procedure. So, I am just** 

### 17 **wondering if DOE did any kind of study to** 

### 18 **determine that the food load that would be in** 

### 19 **the convection portion of the microwave would** 

### 20 **be similar to a typical conventional cooking** 

### 21 **product.** 

### 22 **MR. BATTAGLIA: Right. I think**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 37**  **1 that is sort of how we created that field-use**  

### 2 **factor. We don't have data at this time about** 

### 3 **the typical size of cooking loads. So, the** 

### 4 **field-use factor would attempt to account for** 

### 5 **the duration of a load.** 

### 6 **MS. CLEARY: Thank you.** 

### 7 **MR. BATTAGLIA: Uh-hum.** 

### 8 **MR. BROOKMAN: Additional** 

### 9 **comments?** 

### 10 **(No response.)** 

### 11 **MR. BATTAGLIA: Okay. And again,** 

### 12 **we are seeking comments here on measuring the** 

### 13 **fan-only mode for the convection-only cooking** 

### 14 **cycle length.** 

### 15 **Okay. Now, in the June 2012 NODA,** 

### 16 **DOE presented test results to evaluate** 

### 17 **different test loads and methods for measuring** 

### 18 **the convection-microwave cooking mode. And** 

### 19 **DOE tested real food loads including** 

### 20 **shortening, potatoes, and boneless chicken** 

### 21 **breasts, and, also, one simulation load, which** 

### 22 **was a TX-151 solidifying gel, which is a**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 38**  **1 powder that hydrates when different amounts of**  

### 2 **water are added to it.** 

### 3 **And the test results for both the** 

### 4 **real and simulation food loads showed high** 

### 5 **test-to-test variation. And DOE also noted** 

### 6 **that the lab-to-lab reproducibility would also** 

### 7 **be difficult to maintain, given the** 

### 8 **variability and food loads as they are either** 

### 9 **grown or produced. So, as a result, DOE is** 

### 10 **not proposing to require the use of real or** 

### 11 **simulated food loads for measuring the energy** 

### 12 **consumption of convection microwave ovens.** 

### 13 **Okay. Because DOE was unable to** 

### 14 **identify a test load that produces repeatable** 

### 15 **and reproducible results for the convection** 

### 16 **microwave cooking mode, DOE is proposing to** 

### 17 **use the results from the microwave-only and** 

### 18 **convection-only test cycles, measured energy** 

### 19 **consumption from those test cycles.** 

### 20 **First, because the convection** 

### 21 **microwave cooking cycle length is different** 

### 22 **from the microwave-only and convection-only**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 39**  **1 cooking cycle lengths, DOE is proposing to**  

### 2 **apply a field-use adjustment based on the** 

### 3 **ratio of the convection-microwave cooking** 

### 4 **cycle length to either the microwave-only** 

### 5 **cycle length or the convection-only cooking** 

### 6 **cycle length. So, for the microwave-only** 

### 7 **cycle length, that would be 5.91, and for the** 

### 8 **convection-only cooking cycle length, that** 

### 9 **would be 0.8. And those are based on the** 

### 10 **consumer usage data.** 

### 11 **DOE is proposing that the per** 

### 12 **cycle energy consumption calculation would** 

### 13 **apportion the microwave-only cooking and** 

### 14 **convection-only cooking energy consumptions.** 

### 15 **And that would be based on the amount of time** 

### 16 **a typical convection microwave oven uses each** 

### 17 **of the cooking modes during a single** 

### 18 **convection-microwave cooking cycle length.** 

### 19 **And based upon DOE's review of the products,** 

### 20 **the default convection-microwave cooking mode** 

### 21 **program cycled back and forth between** 

### 22 **convection-only and microwave-only during the**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 40**  **1 single cycle.**  

### 2 **Now DOE is proposing to use** 

### 3 **weighting factors of 30 percent for the** 

### 4 **microwave-only cooking and 70 percent for the** 

### 5 **convection-only cooking. And that was based** 

### 6 **on DOE's testing and review of manuals that** 

### 7 **showed that, for a single cycle, the** 

### 8 **microwave-only accounted for about 30 percent** 

### 9 **of the total cooking time and the convection** 

### 10 **only for the remaining 70 percent.** 

### 11 **So, here we are seeking comment on** 

### 12 **the proposal to calculate consumption for the** 

### 13 **convection-microwave cooking mode based on the** 

### 14 **results from the microwave-only and** 

### 15 **convection-only mode.** 

### 16 **MR. BROOKMAN: Joanna?** 

### 17 **MS. MAUER: Joanna Mauer.** 

### 18 **So, this proposal is because DOE** 

### 19 **wasn't able to develop a method for actually** 

### 20 **measuring energy consumption of that type of** 

### 21 **cycle?** 

### 22 **MR. BATTAGLIA: That is correct,**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 41**  **1 yes. All the food loads that we tested were**  

### 2 **not repeatable or reproducible. So, DOE used** 

### 3 **this method to calculate the convection** 

### 4 **microwave mode.** 

### 5 **MR. BROOKMAN: Thanks.** 

### 6 **MR. BATTAGLIA: Okay. Next,** 

### 7 **again, to the energy use metric. DOE** 

### 8 **considered the data from the LBNL Consumer** 

### 9 **Usage Survey that is presented here in the** 

### 10 **table. And we also, just for information** 

### 11 **purposes, we also included our average test** 

### 12 **cycle average power, and calculated the** 

### 13 **average annual energy use. So, based on the** 

### 14 **testing and the consumer usage data for** 

### 15 **microwave-only ovens, the active mode** 

### 16 **accounted for about 75 percent of the total** 

### 17 **annual energy consumption.** 

### 18 **And again, here we have the** 

### 19 **convection microwave oven annual energy use.** 

### 20 **And again, here, let's see, the fan-only mode** 

### 21 **was estimated based on the units in DOE's test** 

### 22 **sample. So, this is for a microwave that**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 42**  **1 would be capable of fan-only mode after the**  

### 2 **convection-only and convection-microwave oven** 

### 3 **cycles. And for these products, the annual** 

### 4 **energy use accounted for, I believe it was** 

### 5 **about 84 percent of the total annual energy** 

### 6 **consumption.** 

### 7 **So, DOE is proposing to use the** 

### 8 **estimates of consumer use for each operating** 

### 9 **mode to calculate the total annual energy** 

### 10 **consumption for both microwave-only and** 

### 11 **convection microwave ovens. And for** 

### 12 **microwave-only ovens, that would be calculated** 

### 13 **as, first, taking the product of the total** 

### 14 **weighted microwave-only per-cycle energy** 

### 15 **consumption and the total number of annual** 

### 16 **microwave-only cooking cycles, and then, also,** 

### 17 **taking the product of the average standby and** 

### 18 **off mode power, and the allocated annual hours** 

### 19 **for each of those modes, and then, summing the** 

### 20 **results and converting to kilowatt hours.** 

### 21 **And again, similarly for** 

### 22 **convection microwave ovens, DOE is proposing**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 43**  **1 that, first, you would calculate the product**  

### 2 **of the microwave-only, convection-only, and** 

### 3 **convection-microwave per-cycle energy** 

### 4 **consumption and the number of annual cooking** 

### 5 **cycles for each mode for a convection** 

### 6 **microwave oven based on the consumer usage** 

### 7 **data.** 

### 8 **And then, again, the same as for** 

### 9 **microwave-only ovens, the average standby and** 

### 10 **off mode power would be calculated based on** 

### 11 **the number of hours for each of those modes,** 

### 12 **and then, again, summing the results and** 

### 13 **converting it to kilowatt hours.** 

### 14 **So, the total number of standby** 

### 15 **mode and off mode hours would be equal to the** 

### 16 **total number of non-active mode hours. And** 

### 17 **that would be calculated as the number of** 

### 18 **total hours in a year minus the average** 

### 19 **cooking cycle times based on consumer use and** 

### 20 **the measured fan-only mode times for each** 

### 21 **cooking mode.** 

### 22 **DOE is proposing for the split**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 44**  **1 between standby and off mode hours that those**  

### 2 **hours would be split evenly. DOE is not aware** 

### 3 **of any products currently on the market that** 

### 4 **are capable of operating in both standby and** 

### 5 **off mode. So, that is why we are proposing** 

### 6 **the even split between those products.** 

### 7 **Now, for the fan-only mode hours,** 

### 8 **DOE is proposing to scale those times using** 

### 9 **the convection-cycle cooking cycle length** 

### 10 **field-use factor that we discussed before,** 

### 11 **which was 0.26. And that is because the** 

### 12 **convection-only fan-only mode time was based** 

### 13 **on the proposed test method, which was using a** 

### 14 **longer cooking cycle.** 

### 15 **Now, for the convection microwave** 

### 16 **mode fan-only mode hours, DOE believes that** 

### 17 **the fan-only mode time would likely be** 

### 18 **equivalent for the convection-only cooking** 

### 19 **cycle and the convection microwave cooking** 

### 20 **cycles of the same length. DOE observed that** 

### 21 **microwave ovens that operated in fan-only mode** 

### 22 **after the convection-only cooling cycle also**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 45**  **1 operated in fan-only mode after the convection**  

### 2 **microwave cooking cycle. And DOE noted that** 

### 3 **the fan-only mode was either based on the** 

### 4 **cavity temperature or a fixed time based on** 

### 5 **the cooking cycle length.** 

### 6 **So, DOE is proposing to use the** 

### 7 **convection-only fan-only mode time, but** 

### 8 **further scaling that to account for the** 

### 9 **difference between the average convection** 

### 10 **microwave cooking and the convection-only** 

### 11 **cooking cycle lengths based on the consumer** 

### 12 **usage data.** 

### 13 **So, here we are seeking comment on** 

### 14 **that annual energy use metric and, also, we** 

### 15 **are welcoming any additional data on the** 

### 16 **consumer usage habits for all of the operating** 

### 17 **modes for both microwave-only ovens and** 

### 18 **convection microwave ovens.** 

### 19 **Okay. Just to go over a few other** 

### 20 **EPCA requirements, EPCA requires that test** 

### 21 **procedures be reasonably designed to produce** 

### 22 **test results that are representative of**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 46**  **1 average use and must not be unduly burdensome**  

### 2 **to conduct.** 

### 3 **So, looking at that test burden,** 

### 4 **the proposed amendments would add, for** 

### 5 **microwave-only mode, would add those methods** 

### 6 **based on the draft IEC test method. And DOE** 

### 7 **noted that the test equipment would be similar** 

### 8 **to the requirements for the previous DOE test** 

### 9 **procedure, except that it would require two** 

### 10 **additional sized test containers, and those** 

### 11 **are the 600-milliliter and 900-milliliter** 

### 12 **sized containers.** 

### 13 **DOE estimated that the one-time** 

### 14 **investment for test equipment would be on the** 

### 15 **order of about $3,000, which is about $300** 

### 16 **more than the previous DOE test procedure, and** 

### 17 **that is for those additional sized test** 

### 18 **containers.** 

### 19 **And DOE also estimated for the** 

### 20 **labor for testing, for testing a single model,** 

### 21 **it would cost between about $3,000 and $4,200,** 

### 22 **depending on the number of repeat tests**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 47**  **1 required. And that would be about $2,600 to**  

### 2 **$3,600 more than the previous test procedure.** 

### 3 **Now, for convection-only mode,** 

### 4 **again, those procedures have similar** 

### 5 **requirements to the DOE conventional oven test** 

### 6 **procedure. And in addition to the microwave** 

### 7 **only test equipment, testing for this mode** 

### 8 **would add about $400 for the test block for** 

### 9 **that testing. And based on DOE's estimates,** 

### 10 **for the labor DOE estimated that it would cost** 

### 11 **between $600 and $850 to test a single model,** 

### 12 **depending on the number of repeat tests** 

### 13 **required.** 

### 14 **And DOE does not expect these** 

### 15 **costs or time commitments to represent a** 

### 16 **significant burden, and we are tentatively** 

### 17 **concluding that the proposed test method would** 

### 18 **not be unduly burdensome to conduct.** 

### 19 **So, here we are seeking comment on** 

### 20 **the test burden associated with both the** 

### 21 **microwave-only and convection-only test** 

### 22 **methods.**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 48**  **1 MR. BROOKMAN: No additional**  

### 2 **comments?** 

### 3 **(No response.)** 

### 4 **As we promised first thing this** 

### 5 **morning, now is an opportunity for anybody** 

### 6 **that wants to to make final comments,** 

### 7 **additional thoughts on what was covered today.** 

### 8 **Joanna?** 

### 9 **MS. MAUER: Joanna Mauer.** 

### 10 **Just on the integrated metric, I** 

### 11 **am wondering about the relationship of this** 

### 12 **test procedure to the recently-finalized test** 

### 13 **procedure for standby and off mode.** 

### 14 **MR. BROOKMAN: Ashley?** 

### 15 **MS. ARMSTRONG: This is Ashley** 

### 16 **from DOE.** 

### 17 **That has been finalized. As you** 

### 18 **know, we are in the process of a standards** 

### 19 **rulemaking for standby and off for microwaves.** 

### 20 **At this point, that is in the final rule** 

### 21 **development stage.** 

### 22 **This is our proposal for active**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 49**  **1 mode. Should we go down the pathway of**  

### 2 **finalizing this procedure, after we get** 

### 3 **comments, we would evaluate how they work** 

### 4 **together as part of the final rule. And it** 

### 5 **would more be a prospective thing than a** 

### 6 **retrospective thing.** 

### 7 **Okay?** 

### 8 **MR. BROOKMAN: Okay. Additional,** 

### 9 **perhaps final, comments or questions?** 

### 10 **Yes, Jennifer?** 

### 11 **MS. CLEARY: I am just not sure I** 

### 12 **totally understood what you said, Ashley.** 

### 13 **Jennifer Cleary.** 

### 14 **Are you saying that the final rule** 

### 15 **for standby and off mode standards could be** 

### 16 **published before this active mode test** 

### 17 **procedure is finalized? And so, it might** 

### 18 **change, based on this test procedure?** 

### 19 **MS. ARMSTRONG: I don't think I** 

### 20 **said it may change. At this point in time,** 

### 21 **the NOPR has been issued for the test** 

### 22 **procedure; the NOPR has been issued for the**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 50**  **1 standards. Which one comes first is unclear,**  

### 2 **but it is likely that the final rule for** 

### 3 **standby and off would be based on the** 

### 4 **previously-promulgated standby and off test** 

### 5 **procedure.** 

### 6 **MR. BROOKMAN: Thank you, Ashley.** 

### 7 **Okay. Final comments?** 

### 8 **(No response.)** 

### 9 **Nothing additional?** 

### 10 **Ashley, do you want to tell us** 

### 11 **about this final slide?** 

### 12 **MS. ARMSTRONG: Oh, sure. Sure.** 

### 13 **I would just like to thank** 

### 14 **everyone for coming and participating. I hope** 

### 15 **everyone gets out before the big winter storm** 

### 16 **hits.** 

### 17 **As you can see, this is how you** 

### 18 **submit written comments. The comment period** 

### 19 **closes on April 22nd. And if you have** 

### 20 **additional questions or clarities, if you** 

### 21 **happen to run testing between now and then,** 

### 22 **feel free to send us an email and followup.**

### 202-234-4433 **Neal R. Gross & Co., Inc. Page 51**  **1 We are happy to always answer.**  

### 2 **Thanks.** 

### 3 **MR. BROOKMAN: Thanks.** 

### 4 **Take care.** 

### 5 **MR. SHARP: Mark with Panasonic.** 

### 6 **Just a quick question. I am** 

### 7 **refreshing constantly. When will this** 

### 8 **presentation be posted to the DOE website?** 

### 9 **MS. ARMSTRONG: Give us a couple** 

### 10 **of days. Typically, we post them pretty** 

### 11 **quick. Yes, that will be up, but the** 

### 12 **transcript will be about a week or so later.** 

### 13 **MR. SHARP: But the** 

### 14 **presentations --** 

### 15 **MS. ARMSTRONG: Yes, we can get** 

### 16 **that up pretty quick, yes.** 

### 17 **MR. BROOKMAN: And we should thank** 

### 18 **those that joined us via the web.** 

### 19 **Take care.**
