(Test Method)Standard Test Method for Size and Squareness of Resilient Floor Tile by Dial Gage Method
Standard Test Method for Size and Squareness of Resilient Floor Tile by Dial Gage Method
SIGNIFICANCE AND USE
Both dimension and squareness of resilient floor tile are important considerations, because installed flooring may exhibit an objectionable appearance when either or both characteristics deviate from established tolerances. This test method provides a means of determining actual dimensions and squareness by using a single apparatus and procedure.
SCOPE
1.1 This test method covers the determination of both dimensions (length and width) and squareness of resilient floor tile. This test method is intended for use with square tiles ranging from a nominal 9 in. (226 mm) to 40 in. (1016 mm) in dimension.
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 and health practices and determine the applicability of regulatory limitations prior to use.

3. Significance and Use
3.1 Both dimension and squareness of resilient floor tile are important considerations, because installed flooring may exhibit an
objectionable appearance when either or both characteristics deviate from established tolerances. This test method provides a
means of determining actual dimensions and squareness by using a single apparatus and procedure.
4. Apparatus
4.1The apparatus shall consist of four dial gages (referenced A through D in
4.1 The apparatus shall consist of four dial gages and two reference index strips mounted on a flat bedplate in a configuration
that, by rotation of the sample, allows the measurement of all four sides of resilient tile samples (see Fig. 1) and two reference
index strips mounted on a flat bedplate in a configuration that, by rotation of the sample, allows the measurement of all four sides
of resilient tile samples (see Fig. 1). One edge of the bedplate is elevated to create a test surface which is offset or tilted 15 6 1
degrees from horizontal. This offset applies minimal pressure to the test specimen against the longer index strip to ensure
repeatable measurement. A reference plate representing target tile size and squareness is used to zero all dial gages (see Fig. 2).
4.2 Dial Gages—The four dial gages are mounted in guide slots that are machined into the bedplate to allow for measurement
of various tile sizes while remaining within 10% of the corner of the tile edge (for the two corner gages and one squareness gage)
or within the central 10% of the tile edge (for the center gage only). Dial gages may report measurements using either electrical
or mechanical means, but they shall be graduated to read 0.001 in. (0.02 mm) and have a stem travel greater than 0.25 in. (6 mm).
The contact foot of the dial-gage stem shall be flat 0.50–0.75 6 0.001 in. (12.7–19.1 mm 6 0.2 mm) in diameter and exert a total
force of not more than 3.0 6 0.1 ozf (0.83 6 0.003 N). Dial gages shall be securely positioned so that when the reference plate
is in place, the contact foot is extended approximately 50% of its full travel.
4.3 Index Strips—The apparatus contains 2 fixed index strips. A horizontal index strip shall be mounted parallel to and just
inside the lower edge of the bedplate. It shall be 1.5 6 0.1 in. (38 6 3 mm) greater in length and a minimum of twice the thickness
