Summary

ASTM F 3261 Standard Specification for Resilient Flooring in Modular Format with Rigid Polymeric Core

This specification is issued under the jurisdiction of ASTM International Committee F06 on Resilient Floor Coverings.
For the complete text of this standard and other ASTM standards visit the ASTM website at www.astm.org or contact ASTM Customer Service at service@astm.org.

Scope: This specification covers resilient flooring, typically in tile or plank format, that are surface decorated or printed and protected by a clear wear layer utilizing a polymeric rigid core as part of the product structure. This type of floor covering may utilize an attached underlay backer for reduced noise and for reducing issues concerning minor subfloor irregularities.

Intended Use: Commercial, light commercial and residential buildings

Classification: N/A

Class Product Construction	Type Surface Finish	Grade Wear Layer Thickness	Backing
Class I ‐ Printed with clear transparent wear layer	Type A ‐ Smooth Type B ‐ Embossed	Grade 1 Commercial 0.020 in.	Class A – No attached underlay Class B – With attached underlay

Characteristics	Requirements
