ASTM D6962-17

Standard Practice for Operation of a Roller Chair Tester for Pile Yarn Floor Coverings

SIGNIFICANCE AND USE
5.1 This practice is applicable for use in testing the durability of pile yarn floor covering of all types.  
5.2 This practice is designed to simulate the stress on a pile yarn floor covering from the action of weighted roller chair castors over an extended period of time.  
5.3 The specimen is tested under conditions that may simulate an actual flooring installation. This may include the pile yarn floor covering plus a specified underlayment cushion.  
5.4 This practice is used to prepare specimens for additional testing, including but not limited to: visual assessment of delamination of the secondary backing, visual assessment of the pile surface, resistance to delamination measurement, tuft bind, and pile yarn raveling.
SCOPE
1.1 This practice covers a procedure for the operation of a weighted roller chair testing device that rotates and moves across a test specimen of pile yarn floor coverings.  
1.2 This practice is applicable for testing unused pile yarn floor covering of all types.  
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. 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.  
1.5 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.
