Standard Test Method for
Overlength Fiber Content of Manufactured Staple Fiber1

This standard is issued under the fixed designation D 3513; 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 (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers the determination of the percent
by number of overlength or multiple length fibers in a sample
of the manufactured cut staple. The method is applicable to fiber
taken immediately after manufacturing, from the bale, or from
partially processed stock.
NOTE 1—For measurement of length and length distribution of manufactured staple fibers, refer to Test Method D 5103.

1.2 This test method covers procedures using the Fibrosampler Model 335A (inch-pound units), the Fibrosampler Model
335B (SI units), and Fibrosampler combs Model 336.

1.2.1 The Fibrosampler Model 335A is equipped with a
sample plate that has 15.8-mm (5⁄8-in.) diameter sample holes
and is recommended for use on blended staple taken from the
fiber blender or from a carding machine.

1.2.2 The Fibrosampler Model 335B is equipped with a
sample plate that has 10-mm (0.4-in.) diameter sample holes
and is recommended for use on unblended staple as may be
taken from the fiber cutter or from a bale of staple fiber.

1.3 The values stated in either SI units or inch-pound units
are to be regarded separately as the standard. The values stated
in each unit are not exact equivalents; therefore, each unit must
be used independently of the other.

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.
