ASTM F1515 Xenon Arc Test for Resilient Flooring

The American Society for Testing and Materials (previously known as ASTM International) created the ASTM F1515 standard test technique to measure the performance of resilient flooring materials under xenon arc light in a laboratory environment. Rubber, vinyl, linoleum, and other kinds of flooring that are similar to these are resilient flooring materials. These materials are used in both commercial and residential settings.

Overview

The ASTM F1515 test is a standardized laboratory procedure for assessing the colorfastness of resilient flooring materials, including LVT, LVP, and sheet vinyl, under prolonged exposure to light. It simulates the harmful effects of sunlight as it would appear through window glass using a Xenon Arc light source.

When flooring materials are exposed to the UV and infrared radiation found in natural sunshine, they may fade, turn yellow, or change color. An “accelerated aging” environment is defined in ASTM F1515 to predict long-term performance in a fraction of the time.

Scope, Applications, and Benefits

Scope

ASTM F1515 specifies a test method for evaluating the color change resistance of resilient flooring materials when exposed to artificial light using a xenon arc apparatus. The test simulates the effects of indoor daylight exposure through windows, allowing manufacturers and specifiers to assess the color stability and lightfastness of resilient flooring products under controlled conditions.

Applications

Quality assessment of resilient flooring materials (vinyl, LVT, rubber, linoleum, etc.)
Product development and formulation improvement
Compliance testing for flooring performance specifications
Selection of flooring materials for light-exposed interior spaces
Comparative testing for manufacturers, designers, and specifiers

Benefits

Evaluates the color stability of resilient flooring under simulated daylight exposure
Helps predict long-term aesthetic performance in indoor environments
Supports quality control and product development
Assists in comparing the light resistance of different flooring products

Frequently Asked Questions

Resilient floor coverings, including rubber and vinyl, are evaluated for exposure to xenon arc light sources as per ASTM 1515. This enables the assessment of their color retention and endurance properties in conditions akin to natural sunlight.

Flooring specimens are exposed to a xenon arc light source, including light cycles and water spray designed to simulate the sun. The samples' color and appearance changes are checked, and the outcome is presented after a specific exposure duration.

For this test, ΔE is the metric unit measuring the color change of the flooring component due to light exposure. The higher the ΔE value, the higher the color change, which means the material is more light-resistant.

The test enables the manufacturers to determine the degree of resilience of their flooring materials against fading and deterioration over time, an aspect critical to the quality of the products offered to customers.

The standard specimen size for the ASTM F1515 test is generally one hundred (100) mm (four inches) long and wide, with the thickness that corresponds to the flooring material being tested.
