• The Light Transmittance should not change by
more than ±10% when the initial light
transmittance is greater than 20%. Or The Light
Transmittance should not change by more than
±2% expressed in absolute value if the initial light
transmittance is less than or equal to 20%.
• Apparently, the test proves that CNC EVA FILM
LAMINATED GLASS is qualified. The Average Light
Transmittance chagne is less than 1%.

• To measure the durability, the luminous
transmission has been measured by the wavelength
between 380nm and 780nm before 2,000 hours of
exposure to the ULTRAVITALUX lamps.
• A minimum 3 transmission measurements have
been taken from each laminated glass sample and
the average has been calculated from these datas.
• In the end, compare the differences of Light
Transmittance and check the presence of any
faults(bubbles, opaqueness, degumming etc)
