Designation: D6287 25
Standard Practice for
Cutting Film and Sheeting Test Specimens
1
This standard is issued under the fixed designation D6287; 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 practice covers equipment and techniques for
cutting film and sheeting specimens for testing.
2
The speci-
mens are nick-free, non-stretched and can be rapidly prepared.
1.2 The values given in SI units are to be considered
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, health, and environmental practices and deter-
mine the applicability of regulatory limitations prior to use.
NOTE 1—There is no known ISO equivalent to this standard.
1.4 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.

2.1 ASTM Standards:

D882 Test Method for Tensile Properties of Thin Plastic
Sheeting
D2838 Test Method for Shrink Tension and Orientation
Release Stress of Plastic Film and Thin Sheeting
F88/F88M Test Method for Seal Strength of Flexible Barrier
Materials
F1921/F1921M Test Methods for Hot Seal Strength (Hot
Tack) of Thermoplastic Polymers and Blends Comprising
the Sealing Surfaces of Flexible Webs
F2029 Practices for Making Laboratory Heat Seals for
Determination of Heat Sealability of Flexible Barrier
Materials as Measured by Seal Strength
3. Significance and Use
3.1 Many test methods including Test Methods D882,
D2838,F88/F88M,F1921/F1921M, and F2029 require the use
of narrow strips of varying length. The quality of the sample
preparation directly affects test results. This practice describes
three techniques for preparing samples with straight, clean,
parallel edges with no visible imperfections.
NOTE 2—After cutting, each specimen should be examined visually to
ensure the edges are undamaged (free of nicks). On a periodic basis
specimen edge quality should be evaluated by microscopic examination.
To determine when cutting blades need to be replaced or sharpened, a
control chart of tensile strength and percent elongation at break (see Test
Method D882) of a uniform material may be maintained. Tensile strength
and percent elongation at break will decrease as the quality of specimen
cutting decreases.
4. Apparatus and Materials
4.1 Procedure A—A hand rotatable drum cutter (Fig. 1)
containing a 12.7 cm (5 in.) diameter drum with grooves at
12.7 mm (0.5 in.) intervals and a blade holder allowing a blade
to ride in each groove or be raised above the groove.
4.2 Procedure B—A dual blade shear cutter (Fig. 2) with
parallelism tolerances within 0.0254 mm (0.001 in.). The cutter
cuts individual strips of a particular sample width.
4.3 Procedure C—Dies with replaceable razor-blade cutters
are available in many different specimen configurations. The
dies are equipped with a spring-loaded mechanism that allows
easy specimen removal. These dies are mounted on either a
manual or pneumatic press and provide easy replacement of
worn cutting elements.
4.4 Scissors.
4.5 Marker.
4.6 Tape.
5. Procedure
5.1 Procedure A:
5.1.1 Cut film or sheeting to approximately 30 by 30 cm (12
by 12 in.) or desired size within these dimensions. It is
recommended to cut only an individual (single) sheet of film.

This practice is under the jurisdiction of ASTM Committee D20 on Plastics and
is the direct responsibility of Subcommittee D20.19 on Film, Sheeting, and Molded
Products.
Current edition approved Sept. 1, 2025. Published November 2025. Originally
approved in 1998. Last previous edition approved in 2017 as D6287 - 17. DOI:

This practice does not cover all types of techniques which may be used for
cutting film and sheeting specimens.

Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1.2 Mark or number all samples as to identity direction
with respect to material flow, etc.
5.1.3 Place sample on work surface in desired direction and
place a strip of tape on the sample edge with half the width of
the tape overlapping the edge to enable the tape to adhere to the
drum of the cutter.
5.1.4 Remove the taped sample from the work surface and
place taped edge on the drum of the cutter below the blade
holder allowing the sample to lie across the top of the cutter.
NOTE 3—Line the sample up precisely to ensure specimens are cut in
the desired direction of material flow.
5.1.5 Turn the handle until the sample falls onto cutter
drum. Continue to turn the drum and smooth the sample on the
drum.
5.1.6 Tape the free corners of sample if necessary.
5.1.7 Align tape with cutter blades.
5.1.8 Pull blade knob to drop blades just in front of tape.
5.1.9 Rotate the drum with the drum handle.
5.1.10 Raise blades by lifting the front edge of the blade
holder until a click is heard.
5.1.11 Turn drum handle until strips fall away from drum.
5.1.12 Remove strips and place on sheets of paper with
proper identification.
5.2 Procedure B:
5.2.1 Mark or number all samples as to identity direction
with respect to material flow, etc. It is recommended to cut only
an individual (single) sheet of film.
5.2.2 Slide sample underneath dual blades by moving
sample on support platforms until aligned perpendicular to
guide bar.
5.2.3 Using a firm downward motion, press the cutter
handle down.
5.2.4 Slowly release the cutter handle.
5.2.5 Remove strip and place on a sheet of paper with
proper identification.
5.3 Procedure C:
5.3.1 Mark or number all samples as to identity direction
with respect to material flow, etc. It is recommended to cut only
an individual (single) sheet of film.
5.3.2 Examine the cutter blades using a hand magnifier to
ensure there are no nicks or other defects in the blades.

5.3.3 Install the appropriate cutter in the unit in accordance
with the manufacturers instructions.
5.3.4 Place a flat back-up sheet on the cutting platform.
NOTE 4—Polyethylene or polypropylene sheets or cardboard (two to
three mm in thickness) have been found to be satisfactory.
5.3.5 Place the sample on the covered cutting platform
ensuring that there are no creases. If necessary, the edges can
be taped to the platform to keep the sample flat.
5.3.6 Activate the cutter (manually or pneumatically) in
accordance with the manufacturers directions.
5.3.7 Remove the cut specimen from the die and place it on
a sheet of paper with proper identification.
NOTE 5—Although blade life is reported to be very long, the blades
should be inspected prior to mounting as noted in 5.3.2 or, as a general
practice, removed for inspection after every 500 specimens cut. This
interval will vary depending on the types of materials being cut and users
are urged to perform inspections more frequently at first to monitor wear
(Reference Note 2).
