5.1. The test conditions for testing
fluorescent lamp ballasts shall be done in
accordance with ANSI C82.2-2002
(incorporated by reference; see 430.3). DOE
further specifies that the following revisions
of the normative references indicated in
ANSI C82.2-2002) should be used in place of
the references directly specified in ANSI
C82.2- 2002: ANSIC78.81- 2010
(incorporated by reference; see 430.3), ANSI
C82.1-2004 (incorporated by reference; see
430.3), ANSI C82.3-2002 (incorporated by
reference; see 430.3), ANSI C82.11-2002
(incorporated by reference; see 430.3), and
ANSI C82.13-2002 (incorporated by
reference; see 430.3). All other normative
references shall be as specified in ANSI
C82.2-2002.
5.2. Room Temperature and Air
Circulation. The test facility shall be held at
25 2C, with minimal air movement as
defined in ANSI C78.375-1997 (incorporated
by reference; see 430.3).
5.3. Input Voltage. The directions in ANSI
C82.2-2002 (incorporated by reference; see
430.3) section 4.1 should be ignored with
the following directions for input voltage
used instead. For commercial ballasts
capable of operating at multiple voltages, the
ballast shall be tested 277V 0.1%. For
ballasts designed and labeled for residential
applications and capable or operating at
multiple voltages, the ballast shall be tested
at 120V 0.1%. For ballasts designed and
labeled as cold-temperature outdoor sign
ballasts and capable of operating at multiple
voltages, the ballast shall be tested at 120V
0.1%. Ballasts capable of operating at onlyone input voltage shall be tested at that
specified voltage.
6. Test Method
6.1. Ballast Factor
6.1.1. Reference ballast lamp arc power
shall be measured with a reference ballast at
the same frequency as the test ballast in
accordance with ANSI C78.375-1997
(incorporated by reference; see 430.3), ANSI
C78.81-2010 (incorporated by reference; see
430.3), and ANSI C82.3- 2002 (incorporated
by reference; see 430.3). Total reference
ballast lamp arc power shall be equal to the
sum of the reference ballast lamp arc powers
of all the reference lamps used with the test
ballast. Reference ballast lamp arc power
shall be measured once every 24 hours.
6.1.1.1. If the reference ballast
characteristics are not specified in ANSI
C78.81-2010 (incorporated by reference; see
430.3), then the reference ballast lamp arc
power shall be equal to the reference lamp
power value listed in Table A times the
maximum number of lamps the ballast is
designed to operate. The reference lamp
power selected from Table A should be at the
same frequency as the test ballast.
6.2. Ballast Luminous Efficiency.
6.2.1. The ballast shall be connected the
appropriate fluorescent lamps and to
measurement instrumentation as indicated
by the Test Setup in section 4.
6.2.2. The ballast shall be operated for at
least 15 minutes but no longer than 1 hour
until stable operating conditions are reached.
After this condition is reached, concurrently
measure the parameters described in sections
6.2.3 through 6.2.9.
6.2.2.1. Stable operating conditions are
determined by measuring lamp arc voltage,current, and power once per second in
accordance with the setup described in
section 4. Once the difference between the
maximum and minimum values for lamp arc
voltage, current, and power do not exceed
one percent over a four minute moving
window, the system shall be considered
stable.
6.2.3. Lamp Arc Voltage. Measure lamp arc
voltage (volts) using the setup described in
section 4.4.2.
6.2.4. Lamp Arc Current. Measure lamp arc
current (amps) using the setup described in
section 4.4.3.
6.2.5. Lamp Arc Power. The power
analyzer shall calculate output power by
using the measurements described in section
6.2.3 and 6.2.4.
6.2.6. Input Power. Measure the input
power (watts) to the ballast in accordance
with ANSI C82.2-2002 (incorporated by
reference; see 430.3), section 7.
6.2.7. Input Voltage. Measure the input
voltage (volts) (RMS) to the ballast in
accordance with ANSI C82.2-2002
(incorporated by reference; see 430.3),
section 3.2.1 and section 4.
6.2.8. Input Current. Measure the input
current (amps) (RMS) to the ballast in
accordance with ANSI C82.2-2002
(incorporated by reference; see 430.3),
section 3.2.1 and section 4.
6.2.9. Lamp Operating Frequency. Measure
the frequency of the waveform delivered
from the ballast to any lamp in accordance
with the setup in section 4.
