Standard Test Method for Measuring Recovery Properties of Floor Coverings after Static Loading

Fecha:
2018-11-05 /Active
Significance and Use:

3.1 This test method is a meaningful test for determining the indentation recovery properties of uninstalled resilient floor covering.3

3.2 This test method is intended solely for the purpose of determining compliance, where applicable, with static load requirements set forth in resilient flooring product specifications under the jurisdiction of ASTM Committee F06 on Resilient Floor Coverings.

3.3 As testing is conducted on uninstalled flooring, results are not an indicator of the floor covering's installed performance.3

Scope:

1.1 This test method is intended for use in determining the recovery properties of uninstalled resilient floor covering after long-term indentation test, 24 h under the load specified in the detail specification. The reported value, residual indentation, is the depth of the depression remaining 24 h after removal of the specified load.

1.2 This test method is not intended for use in evaluating the long-term indentation resistance or recovery properties, or both, of resilient floor coverings at loads above those listed in the Precision and Bias statement as described in Section 10.

1.2.1 Testing at loads above 250 psi is outside the scope of this test method.

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.
