ASTM F1482-21

Standard Practice for Installation and Preparation of Panel Type Underlayments to Receive Resilient Flooring

SIGNIFICANCE AND USE
4.1 This practice provides minimum recommendations for the installation and preparation of wood-based, fiber-reinforced gypsum and fiber-cement panel underlayments suitable to receive resilient floor coverings. Actual requirements for materials to be used, mixtures, and other details are generally included as part of project plans or specification detail and may vary from the minimum recommendations set forth in this practice.
SCOPE
1.1 This practice includes recommendations for the installation of panel type underlayments including wood based, fiber reinforced gypsum and fiber-cement panel underlayment/subfloor assemblies upon which resilient flooring may be installed.  
1.2 The structural integrity of subfloor assemblies is governed by local building codes.  
1.3 This practice does not supersede in any manner the resilient flooring, underlayment or adhesive manufacturer's written instructions. Consult the individual resilient flooring, underlayment or adhesive manufacturer for specific recommendations. Manufacturer's instructions supercede the recommendations included in this practice.  
1.4 See Supplementary Requirements for “Select Warnings” that have been provided.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
