ASTM F2055-00(2008)

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 the standard. The values given in parentheses are for information only.
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.

Standard Test Method for
Size and Squareness of Resilient Floor Tile by Dial Gage
Method
This standard is issued under the fixed designation F 2055; 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 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 the standard. The values given in parentheses are for
information only.
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 appro-
priate safety and health practices and determine the applica-
bility of regulatory limitations prior to use.

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.
