D. Weathering Requirement:
Prior to testing, operate three decorative light strings for a 24 hour (± 1%) seasoning period at 120 V ± 1 V RMS AC.
Assemble the three decorative light strings into three flat test configurations. For each, wrap the string around a rigid
board or frame so that all are mechanically supported and oriented with the lamps directed outward. Tape the assembly
together with electrical tape to maintain the relative positioning of the lamps throughout the test. Next, for its optical
properties, white Teflon® tape shall be wrapped around the assembly to completely cover the electrical tape and wiring
harnesses. Ensure that the Teflon tape does not cover any part of the lamp or lamp socket.
Measure the light output of the assemblies while operating at 120 V ± 0.5 V RMS AC, 25°C ± 5°C and following the
guidelines contained in CIE Publication 084-1989, The Measurement of Luminous Flux. For decorative light strings that
modulate their light output (e.g., flashing, changing color), light output shall be measured over at least five (5) complete
cycles.
Keeping the testing assemblies intact, load them into the testing chamber. The decorative light strings under test shall be
operated for the duration of this test at 120 V ± 3 V RMS AC inside the testing chamber. Each cycle of this test includes 8
hours of UV light (340 nm at 1.55 W/m²/nm) at 60°C, 0.25 hours of water spray, and 3.75 hours of condensation at 50°C.
The strings shall be subjected to 20 consecutive iterations of Cycle 7 under Table X2.1 of ASTM G154-06 for a total of
240 hours.
After completing the output and reliability (previously referred to as lifetime) test, conduct a second measurement of the
light output on the respective sample of lamps following the same procedure above. Calculate the average maintained
light output for the three strings tested relative to the initial average measurement for those same strings.
For strings with colored lamps, the average maintained light output shall be no less than 70%. For strings with white
lamps or any phosphor-based lamps, the average shall be no less than 50%.
A lamp has failed if the light output is less than half the expected output for a comparable lamp of the same age in good
condition. This will normally be determined by comparison with a good lamp of the same color on the same string.
The average percentage of failed lamps on all three strings in the sample shall be no greater than 3%.
