ASTM F3261 Test Standard for SPC Flooring
Rigid core resilient flooring (SPC) is to point to by rigid core material as the main structure of the polymer, surface transparent wear-resisting layer, the back has a lower noise of elastic floor, with high mechanical properties, fire prevention, aging resistant, antistatic, good dimensional stability, such as performance, widely used in home decoration, hospitals, shopping malls and other public places, are widely used by customers at home and abroad.
ASTM F3261 is American Test Standard for resilient flooring. There are two versions of it ASTM F3261 2017 and ASTM F3261 2020.
The main test characteristics covers Composition of material, Size, tolerance,Thickness, Squareness, Flatness, Opening, Ledging, Residual indentation, Surface integrity, Dimensional stabiliyu, Curl, Resistance to chemicals, Resistance to heat, Resistance to light, Static load.
For Residential flooring and commercial flooring, the test requirements are different. Please check the following table for more details:
