Standard: ANSI/NALFA LF-01 Section 3.3 – Light Resistance

Certification Required: Required for the NALFA Certification Seal

Scope: Per ANSI/NALFA LF-01 Section 3.3: "This test measures the ability of laminate flooring to retain its color when exposed to a light source having a frequency range approximating sunlight through window glass. It is not intended to show the resistance to continuous exposure to outdoor weathering conditions."

Applicable Products: Laminate flooring

Test Procedure: Test specimens are loaded into a Xenon-arc accelerated weathering machine that is programmed to the parameters defined by the standard. The specimens are masked so that approximately half of the specimen face is covered. After 100 hours of exposure the samples are removed from the machine and allowed to recover for 24 hours without exposure to light. Once the recovery period is complete the specimens are visually inspected at a distance of 30 to 36 inches at an angle of approximately 45 ̊to 75 ̊. Any changes in color or surface finish are noted.

End Result: This test results in the light resistance of the flooring specimens.
