10:3.0.1.4.18.2.13.6.17 : Appendix I
Appendix I to Subpart B of Part 430 - Uniform Test Method for
Measuring the Energy Consumption of Cooking Products 1. Definitions
The following definitions apply to the test procedures in
this appendix, including the test procedures incorporated by
reference:
1.1 Active mode means a mode in which the product is
connected to a mains power source, has been activated, and is
performing the main function of producing heat by means of a gas
flame, electric resistance heating, electric inductive heating, or
microwave energy.
1.2 Built-in means the product is enclosed in surrounding
cabinetry, walls, or other similar structures on at least three
sides, and can be supported by surrounding cabinetry or the
floor.
1.3 Combined cooking product means a household cooking
appliance that combines a cooking product with other appliance
functionality, which may or may not include another cooking
product. Combined cooking products include the following products:
Conventional range, microwave/conventional cooking top,
microwave/conventional oven, and microwave/conventional range.
1.4 Drop-in means the product is supported by horizontal
surface cabinetry.
1.5 IEC 62301 (First Edition) means the test standard
published by the International Electrotechnical Commission, titled
“Household electrical appliances - Measurement of standby power,”
Publication 62301 (First Edition 2005-06) (incorporated by
reference; see § 430.3).
1.6 IEC 62301 (Second Edition) means the test standard
published by the International Electrotechnical Commission, titled
“Household electrical appliances - Measurement of standby power,”
Publication 62301 (Edition 2.0 2011-01) (incorporated by reference;
see § 430.3).
1.7 Normal non-operating temperature means a temperature
of all areas of an appliance to be tested that is within 5 °F (2.8
°C) of the temperature that the identical areas of the same basic
model of the appliance would attain if it remained in the test room
for 24 hours while not operating with all oven doors closed.
1.8 Off mode means any mode in which a cooking product is
connected to a mains power source and is not providing any active
mode or standby function, and where the mode may persist for an
indefinite time. An indicator that only shows the user that the
product is in the off position is included within the
classification of an off mode.
1.9 Standby mode means any mode in which a cooking
product is connected to a mains power source and offers one or more
of the following user-oriented or protective functions which may
persist for an indefinite time:
(1) Facilitation of the activation of other modes (including
activation or deactivation of active mode) by remote switch
(including remote control), internal sensor, or timer;
(2) Provision of continuous functions, including information or
status displays (including clocks) or sensor-based functions. A
timer is a continuous clock function (which may or may not be
associated with a display) that allows for regularly scheduled
tasks and that operates on a continuous basis.
2. Test Conditions
2.1 Installation. Install a drop-in or built-in cooking
product in a test enclosure in accordance with manufacturer's
instructions. If the manufacturer's instructions specify that the
cooking product may be used in multiple installation conditions,
install the appliance according to the built-in configuration.
Completely assemble the product with all handles, knobs, guards,
and similar components mounted in place. Position any electric
resistance heaters and baffles in accordance with the
manufacturer's instructions.
2.1.1 Microwave ovens, excluding any microwave oven component
of a combined cooking product. Install the microwave oven in
accordance with the manufacturer's instructions and connect to an
electrical supply circuit with voltage as specified in section
2.2.1 of this appendix. Install the microwave oven also in
accordance with Section 5, Paragraph 5.2 of IEC 62301 (Second
Edition) (incorporated by reference; see § 430.3), disregarding the
provisions regarding batteries and the determination,
classification, and testing of relevant modes. A watt meter shall
be installed in the circuit and shall be as described in section
2.6.1.1 of this appendix.
2.2 Energy supply.
2.2.1 Electrical supply.
2.2.1.1 Voltage. For microwave oven testing, maintain the
electrical supply to the unit at 240/120 volts ±1 percent. Maintain
the electrical supply frequency for all products at 60 hertz ±1
percent.
2.3 Air circulation. Maintain air circulation in the room
sufficient to secure a reasonably uniform temperature distribution,
but do not cause a direct draft on the unit under test.
2.4 Ambient room test conditions.
2.4.1 Standby mode and off mode ambient temperature. For
standby mode and off mode testing, maintain room ambient air
temperature conditions as specified in Section 4, Paragraph 4.2 of
IEC 62301 (Second Edition) (incorporated by reference; see §
430.3).
2.5 Normal non-operating temperature. All areas of the
appliance to be tested must attain the normal non-operating
temperature, as defined in section 1.7 of this appendix, before any
testing begins. Measure the applicable normal non-operating
temperature using the equipment specified in sections 2.6.2.1 of
this appendix.
2.6 Instrumentation. Perform all test measurements using
the following instruments, as appropriate:
2.6.1 Electrical Measurements.
2.6.1.1 Standby mode and off mode watt meter. The watt
meter used to measure standby mode and off mode power must meet the
requirements specified in Section 4, Paragraph 4.4 of IEC 62301
(Second Edition) (incorporated by reference; see § 430.3). For
microwave oven standby mode and off mode testing, if the power
measuring instrument used for testing is unable to measure and
record the crest factor, power factor, or maximum current ratio
during the test measurement period, measure the crest factor, power
factor, and maximum current ratio immediately before and after the
test measurement period to determine whether these characteristics
meet the requirements specified in Section 4, Paragraph 4.4 of IEC
62301 (Second Edition).
2.6.2 Temperature measurement equipment.
2.6.2.1 Room temperature indicating system. For the test
of microwave ovens, the room temperature indicating system must
have an error no greater than ±1 °F (±0.6 °C) over the range 65° to
90 °F (18 °C to 32 °C).
3. Test Methods and Measurements
3.1. Test methods.
3.1.1 Microwave oven.
3.1.1.1 Microwave oven test standby mode and off mode power
except for any microwave oven component of a combined cooking
product. Establish the testing conditions set forth in section
2, Test Conditions, of this appendix. For microwave ovens that drop
from a higher power state to a lower power state as discussed in
Section 5, Paragraph 5.1, Note 1 of IEC 62301 (Second Edition)
(incorporated by reference; see § 430.3), allow sufficient time for
the microwave oven to reach the lower power state before proceeding
with the test measurement. Follow the test procedure as specified
in Section 5, Paragraph 5.3.2 of IEC 62301 (Second Edition). For
units in which power varies as a function of displayed time in
standby mode, set the clock time to 3:23 and use the average power
approach described in Section 5, Paragraph 5.3.2(a) of IEC 62301
(First Edition), but with a single test period of 10 minutes +0/−2
sec after an additional stabilization period until the clock time
reaches 3:33. If a microwave oven is capable of operation in either
standby mode or off mode, as defined in sections 1.9 and 1.8 of
this appendix, respectively, or both, test the microwave oven in
each mode in which it can operate.
3.2 Test measurements.
3.2.1 Microwave oven standby mode and off mode power except
for any microwave oven component of a combined cooking product.
Make measurements as specified in Section 5, Paragraph 5.3 of IEC
62301 (Second Edition) (incorporated by reference; see § 430.3). If
the microwave oven is capable of operating in standby mode, as
defined in section 1.9 of this appendix, measure the average
standby mode power of the microwave oven, PSB, in watts as
specified in section 3.1.1.1 of this appendix. If the microwave
oven is capable of operating in off mode, as defined in section 1.8
of this appendix, measure the average off mode power of the
microwave oven, POM, as specified in section 3.1.1.1.
3.3 Recorded values.
3.3.1 For microwave ovens except for any microwave oven
component of a combined cooking product, record the average standby
mode power, PSB, for the microwave oven standby mode, as determined
in section 3.2.1 of this appendix for a microwave oven capable of
operating in standby mode. Record the average off mode power, POM,
for the microwave oven off mode power test, as determined in
section 3.2.1 of this appendix for a microwave oven capable of
operating in off mode.
