(Specification)Standard Specification for Concrete Floor Tile
Standard Specification for Concrete Floor Tile
ABSTRACT
This specification establishes the product criteria and minimum performance requirements for concrete floor tile (CFT) used as interior and exterior flooring. The units described by this specification are manufactured from cementitious materials, mineral aggregates (normal weight, lightweight, or both), water, and additives that are cast into various textures and shapes, often simulating natural stone, brick, terracotta, saltillo, and others. The standard addresses materials and their manufacture, physical properties, sampling, packaging and package marking, and certification.
SCOPE
1.1 This specification covers concrete floor tile (CFT) for application as interior and exterior flooring. The units described by this specification are manufactured from cementitious materials, mineral aggregates (normal weight, lightweight, or both), water, and additives that are cast into various textures and shapes, often simulating natural stone, brick, terracotta, saltillo, and others.
1.2 This specification is limited to requirements for the physical attributes for the CFT units.
1.3 The use of results from testing installed CFT units that have been removed from use for determining conformance or nonconformance to the requirements of this specification is beyond the scope of this specification.
1.4 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.
1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
1.6 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
