Standard Practice for the Operation of the Hexapod Tumble Drum Tester
SIGNIFICANCE AND USE
5.1 This equipment may be used to bring about the changes in appearance and texture on the surface of pile floor covering caused by mechanical action.
SCOPE
1.1 This practice describes the equipment and operation of the hexapod tumble drum tester for testing pile floor covering to produce changes in appearance and color due to changes in surface structure by mechanical action tester.
1.2 This practice is applicable for use in testing unused pile floor covering of all types. It is not applicable for use in testing used pile yarn floor coverings.
1.3 This practice may be used by mutual agreement between the purchaser and supplier to set purchasing specifications.
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, health, and environmental 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.
