【国外标准】 Standard Practice for Testing the Performance of Clear Floor Sealers (Withdrawn 2008)

Several coating systems are used to finish or refinish wood floors of the interior of commercial and residential buildings. One system that has commonly been used by home owners and floor refinishers consists of applying two coats of a sealer, frequently of the oleoresinous type, to the wood followed by one or two coats of a durable floor wax. The advantages of this system are the ease of application and, compared to urethane coatings, the facility of refinishing by touching up only the worn areas. This practice is used to establish whether a floor sealer will perform adequately.1.1 This practice covers the testing of clear floor sealers, intended for use on interior wood floors. It covers the appearance of the sealed wood and of treated worn spots, the resistance of the sealed wood to ink stains, and the appearance of the complete system after the sealer has been coated with varnish, and with solvent- and waterborne waxes.Note 1—The resistance of the sealer to other reagents may be determined using appropriate parts of the procedure, when agreed upon between the purchaser and the seller.1.2 The values stated in inch-pound units are standard. The values given in parentheses are for information only.1.3 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.
