ASTM F3191-16

1.1 This practice covers the determination of whether or not a substrate surface, in lieu of written instruction from a product manufacturer, is considered porous or non-porous prior to the installation of resilient flooring materials.

1.2 Although carpet tiles, carpet, wood flooring, coatings, films, paints, self-leveling and trowel-grade underlayments, primers, and other associated products are not specifically intended to be included in the category of resilient floor coverings, the procedures included in this practice may be useful for assessing the substrate water absorption for substrates to receive such materials.

1.3 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.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.
