ASTM D6283-98

Standard Test Method for Tuft Element Length of Uncoated Pile Yarn Floor Coverings

SCOPE
1.1 This test method covers the measurement of tuft length and pile yarn length of uncoated pile floor coverings.
1.2 Usually the tuft elements measured as directed in this test method will each be bound at only one binding site, but this test method also may be used for tuft elements bound at more than one binding site, provided that every tuft element measured is bound at the same number of binding sites.
1.3 The values stated in SI units are to be regarded as standard. The values stated in inch-pound units are provided as information only and are not exact equivalents. In case of referee decisions, the SI units shall prevail.
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. Scope
1.1 This test method covers the measurement of tuft length
and pile yarn length of uncoated pile floor coverings.
1.2 Usually the tuft elements measured as directed in this
test method will each be bound at only one binding site, but
this test method also may be used for tuft elements bound at
more than one binding site, provided that every tuft element
measured is bound at the same number of binding sites.
1.3 The values stated in SI units are to be regarded as
standard. The values stated in inch-pound units are provided as
information only and are not exact equivalents. In case of
referee decisions, the SI units shall prevail.
1.4 This practice does not purport to address all of the
safety concerns, if any, associated with its use. It is the
