Designation: D 5264 – 98 (Reapproved 2004)
Standard Practice for
Abrasion Resistance of Printed Materials by the Sutherland
Rub Tester1
This standard is issued under the fixed designation D 5264; 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 practice covers a procedure for determining the
abrasion resistance of printed materials using the Sutherland
Rub Tester, or its equivalent, equipped with full-width rubber
pads and using standardized receptors.
1.2 This practice is applicable to labels, folding cartons,
corrugated boxes, inserts, circulars, and other packaging materials
having applied graphics on a flat substrate.
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. Terminology
3.1 General definitions for packaging and distribution are
found in Terminology D 996.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 abrasion resistance—ability of a printed surface to
resist mechanical destruction.
3.2.2 abrasiveness—the degree to which another material
can abrade the surface of the test specimen.
3.2.3 receptor—film or paper of a specified abrasiveness
onto which coatings (for example, ink or protective coating)
removed from the specimen are deposited during the abrasion
test.
4. Summary of Practice
4.1 The test specimen is mounted on top of the rubber pad
on the Sutherland base and the receptor is cut to fit the 0.91-kg
(2-lb) or the 1.81-kg (4-lb) weight (depending on which one is
being used). The receptor is mounted to the weight. The test
duration is determined by the number of strokes (a stroke is one
back-and-forth cycle) the sample is rubbed. The number of
strokes desired is preset on the Sutherland Timer. The weight is
mounted on the Sutherland and the machine is turned on. The
Sutherland will shut off automatically when the desired number
of strokes is completed.
4.2 The test specimen is removed from the Sutherland base
and examined for degree of print degradation. The receptor is
analyzed for the amount of ink transferred from the specimen.
Results are compared to an agreed upon standard sample tested
in the identical fashion.
5. Significance and Use
5.1 Abrasion resistance is a desirable and sometimes critical
property of printed materials. Abrasion damage can occur
during shipment, storage, handling, and end use. The result is
a significant decrease in product appearance and legibility of
product information. The amount of abrasion damage to a
printed substrate is dependent on shipping conditions, possibly
temperature and humidity, time, and many other variables. This
practice provides a way of comparing abrasion resistance of
printed materials under laboratory conditions.
5.2 This practice also can be used to evaluate the relative
abrasion resistance of printed inks, coatings, laminates, and
substrates.
5.3 This practice can be modified to measure the effects of
the product (detergent powder, food, beverages, etc.) on
abrasion resistance, as may occur in spillage or leakage in
transit.

direct responsibility of Subcommittee D10.14 on Tapes and Labels.

5.4 This practice can provide a reasonably simple procedure
that can be used by both the buyer and the seller of printed
materials to determine if the product offered for sale meets
some predetermined standard for abrasion or scuff resistance.
6. Apparatus
6.1 Sutherland Rub Tester, 3 or its equivalent. See Fig. 1 for
a photograph of the Sutherland Tester and its attachments.
7. Materials
7.1 Standard receptors cut to fit the Sutherland Receptor
Block 51 by 178 mm (2 by 7 in.). The receptor is then creased,
using the scoring block that comes with the Sutherland Rub
Tester. If not available, the receptor can be cut to 51 by 102 mm
(2 by 4 in.) and fastened with pressure-sensitive tape outside
the test area. An appropriate receptor from the following list
should be selected in accordance with 8.2:
7.1.1 Unprinted Sheet of Substrate,
7.1.2 Printed Sheet Identical to Substrate (face-to-face),
7.1.3 Pressure-sensitive tape or any tape suitable for holding
the sample without interfering with the operation of the tester.
8. Preparation of Apparatus
8.1 Set the Sutherland Rub Tester on a sturdy bench,
preferably in a room conditioned at 23 6 1°C (73.4 6 2°F) and
50 6 2 % relative humidity, as described in Practice D 4332.
8.2 If test criteria have not been specified, select an appropriate
receptor by running an agreed-upon reference material
for the number of strokes required to achieve a visible level of
degradation.
NOTE 1—An excessively high number of strokes should be avoided
because this condition can generate heat which may alter the results.
9. Specimen Preparation and Conditioning
9.1 The specimen should preferably be a flat sample with no
scoring, ridges, or other surface irregularities. Further, in
testing multiple samples, it is important that each has comparable,
if not identical, ink coverage and ink density.
9.2 Cut the specimen 76 by 152 mm (3 by 6 in.) whenever
possible. Smaller samples may be tested as long as they are
mounted to a 76 by 152-mm (3 by 6-in.) template. (Smaller
samples such as 20-mm (0.79-in.) round die-cut labels may not
give the same results as a full-size sheet 76 by 152 mm (3 by
6 in.).
9.2.1 The machine direction of the sample should be parallel
to the 76-mm (3-in.) width. The intent of this test method is
to rub across the machine direction.
9.2.2 Care should be taken to avoid contaminating the
sample with fingerprints during handling.
9.3 Condition the specimen at 23 6 1°C (73.46 2°F) and 50
6 2 % relative humidity, as described in Practice D 4332,
unless otherwise agreed upon.
10. Procedure
10.1 Mount a 76 by 152-mm (3 by 6-in.) rubber pad3 both
on top of the Sutherland base as well as to the bottom face of
the detectable receptor block.
NOTE 2—This pad will need periodic replacing as the rubber becomes
brittle due to oxidation or if the rubber wears off the pad. This periodic
replacing is also true of the pads that come with the Sutherland receptor
block. Failure to replace worn pads could result in distorted test results.
The pad face should be uniformly flat (level) with a Shore A durometer of
15 6 5.
10.2 Mount the receptor to the rubber pad of the receptor
block with pressure sensitive tape, outside the test area [only if
using the 51 by 102-mm (2 by 4-in.) receptor].
10.3 Attach the test specimen to the rubber pad on the
Sutherland base with the test surface face exposed.
NOTE 3—The choice of receptor block is based on the type of substrate
being tested. The heavier block, 1.82 kg (4.0 lb), is appropriate for
samples that experience severe shipping and handling conditions.
10.4 Attach the receptor to the receptor block. The 51 by
178-mm (2 by 5-in.) receptor is held in place by the clamps on
the sides of the block, while the 51 by 102-mm (2 by 4-in.)
receptor is held in place by the pressure-sensitive tape.

10.5 Lightly brush the sample and receptor with a camel’s
hair anti-static brush to remove any potentially abrasive
particles from the surface.
10.6 Place the receptor block in the receptor block holder.
10.7 Preset the dial on the Sutherland Rub Tester to the
desired number of strokes.
10.8 Turn the Sutherland on. It will automatically shut off
when the preset number of strokes has been completed.
10.9 Repeat 10.1 through 10.8 with each test specimen.
10.10 Repeat 10.1 through 10.8 with the reference standard.
11. Evaluation
11.1 Examine each specimen for degree of degradation and
each receptor for the amount of material transferred from the
print.
11.2 Report test conditions and results for abrasion using
predetermined criteria established by the interested parties.
