(Test Method)Standard Test Method for Deflection of Resilient Floor Tile
Standard Test Method for Deflection of Resilient Floor Tile
SIGNIFICANCE AND USE
3.1 This test method measures physical properties associated with resilient floor tile's ability to conform to an uneven subfloor without breaking or cracking.
SCOPE
1.1 This test method is used to determine the deflection of relatively rigid resilient floor tile such as vinyl composition tile and resilient flooring with a rigid polymeric core.
1.2 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.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

the long dimension across the machine direction. These samples are tested for deflection.
6. Preparation of Apparatus
6.1 Install the deflection frame in the tensile tester. Check to see that the three bars are parallel, and that the center bar is
accurately centered between the two outside bars. Position the frame so that the test sample can be placed with the wearing surface
touching the center bar, and the back surface touching the two outer bars, without deflection of the sample. This is the zero point

for measuring deflection. Check that the deflection speed of the tester is 4 6 ⁄8 in./min. (102 6 3 mm/min.). Check the deflection
measuring device to see that it accurately measures the relative movement between the center bar and the frame holding the two
outer bars.
