ASTM F1304-18

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
of the standard as published by ASTM is to be considered the official document.
Designation: F1304 − 08 (Reapproved 2013) F1304 − 18
Standard Test Method for
Deflection of Resilient Floor Tile
This standard is issued under the fixed designation F1304; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method is used to determine the deflection of relatively rigid resilient floor tile such as vinyl composition tile. 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 safety, health, and healthenvironmental 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.

FIG. 1 Deflection Frame
5.3 Six samples shall be taken from each test unit, three cut with the long dimension in the machine direction, and three with
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.
NOTE 1—If a pendulum-type weighing system is used on the test machine, which has appreciable movement of the attached jaw, the mechanism may
be locked in place to make measurement of the deflection easier, and to maintain the specified deflection rate, since measurement of the load is not
