Test description
Condition
Luminance and color
evaluation method
Cut sample with the length of 1000mm was inserted into each testing conditions. After dwelled the samples left at room
temperature for at least 30minutes before measurements.
＊Note4
, inserted into transparent linear pipe, and then the side
Either end of sample was connected to a 1W white LED
luminance and the color was measured at the 10, 20, 30, 40, 50, 60, 70, 80, 90cm points from the LED connection end.
Outer diameter evaluation The outer diameter was measured at 6 points in the circumferential direction at points near the exact center in the lengthwise
direction of each sample.
method
Length evaluation method Each sample was inserted into 10mm-width linear grooves, and the length was measured.
*Note1　The luminance variation is based on human perception, and so the effect of the rate of variation was measured based on the Fechner's law which states
that the strength of a sensation is proportional to the logarithm of the stimulus. Normally the range of -50% to +100% is considered to have no effect.
*Note2　Color variation was determined by the effect of color variation based on the CIE chromaticity diagram developed by the International Commission on Illumination
(CIE) in 1931 (ref. next figure)
*Note3　The protrusion of core part with 1-2 mm length may occure at both ends due to shrinkage of cladding after a series of durability test.
*Note4　Light flux: 45 lumens, Directional pattern (2Θ1/2）：110°

Notes
1. Dark spots may occur in illumination from the cut surface to about 10mm due to air gap between the core and cladding.
2.　Do not repeatedly bend, stretch, or subject the Light String to strong impact. This could damage it.
3.　Be careful not to damage the Light String when installing it. If it hits a hard object or scrapes against the floor, the cladding can be damaged,
and the illumination quality can be adversely affected.
4.　Do not apply high tension to the Light String when connecting or securing it. If it is stretched, the illumination quality can be adversely affected.
5.　Please contact 3M about displacement absorption methods in the longitudinal direction.
