ate safety practices for use with this equipment and the individual material be-
ing tested.
Warning!
The Gardner-scrub Abrasion Tester is designed and intended for the use de-
scribed in this manual. Using the Abrasion Tester for other purposes for which
it was not designed may reduce or eliminate the protection offered by the fea-
tures of the applicator. Serious injury may result.
Warning!
Never defeat the ground conductor or operate the equipment in the absence
of a suitably installedground conductor. Contact the appropriate electrical in-
spection authority or an electricianif you are uncertain that suitable grounding
is available.
Warning!
Ultimate disposal of this product should be handled according to all national
laws and regulations.
Attention!
The Gardner-scrub Abrasion Tester works with a moving traverse carriage. No
parts of the carriage may be touched or held during operation. Once the “Run”
button is pressed no work should be carried out within the travel area of the
carriage.
Please note the following points:
• During testing operation the carriage oscillates across the top surface of
the instrument.
• Familiarize yourself with the layout and operation of the controls.
• Pressing anywhere on the screen while the instrument is running will im-
mediately stop the carriage at any point of its travel.
• Ensure the operator has no loose clothing or jewelry which could become
caught in the moving parts.

3 System Description
The Gardner-scrub Abrasion Tester helps evaluate washability and abrasion re-
sistance of a material. The tester reciprocates an abrasive device linearly over a
sample. The abrasion device can be a brush, sponge, abrasive pads, and other
abraders. The traversing carriage is designed to hold 1, 2 or 3 abrading devices
depending on their size.
Two sample clamps slide on shafts at the rear of the instrument to allow vari-
ous sized samples to be held in place during testing. The clamps will also hold
“Lilly Frames” or other accessories in place.
Gardner-scrub with 3 ASTM brush boxes mounted
The Gardner-scrub incorporates a precise speed control to maintain a constant
speed for the test. The instrument is preset at 37 strokes per minute to coincide
with most standardized tests but may be adjusted within the range of 6 to 60
strokes per minute. Unlike some other instruments on the market, the Gardner-
scrub maintains a linear speed over its travel length. The result is a more consis-
tent and repeatable test.
A front mounted, color touch screen is provided for user interaction. All adjust-
ments are available in the setup screen to provide a flexible interaction with
the user.
The instrument is setup at the factory for a center-to-center stroke length of 10
inches. Stroke lengths of 9 or 11 inches may be achieved by means of a me-
chanical adjustment. This adjustment must be performed by the factory o ran
authorized service center.

6 Operation
Specific brushes, holders or other apparatus are specified in the various interna-
tional standards and those should be referenced to setup the appropriate test
parameters.
The carriage is designed to accommodate several different brush, sponge, and
abrasive pad holders.
Multiple holes are provided to allow one, two or three holders at the same
time.
Multiple holder options are limited to the size of the holder.
Currently, the unit will accommodate up to 3 standard brush holders, up to 3
abrasive pad holders or up to 2 sponge holders.
The holder is released by lifting the black knob located at the rear center of the
holder.
For convenience, the holder may be completely removed by squeezing the two
pins on the hinge together.
Install your desired abraders, the test sample, and any liquids in the test pan.
You are now ready to begin testing!

BYK-Gardner Abrasion Tester

On the “Home” screen press the large “Start” but-
ton to start testing. Once you press this button the
screen will change to the “Run” screen.
When the “Start” button is pressed, the screen
changes to the “Run” mode. The “Start button”
turns blue and is now a “Pause” button. The
“Stop” button is now active and is indicated by the
red square. The “Progress” bar is in blue to help
indicating how far along the test has run. To pause
operation without resetting the counter, press the
large blue “Pause” button. To stop operation and
reset the counter, press the red square area with
the “Stop” button.
When the “Pause” button is pressed (or anywhere
except the “Stop “button area) the “Pause” screen
will appear. To resume the test just press the yel-
low “Run” button. In our example the counter is
stopped at 20 cycles on its way to a total of 100 cy-
cles. Note the “Progress” bar is also yellow. Press-
ing the “Start” button will continue from where
the test was stopped. Pressing the “Stop” button
will stop the test and reset the counter.
As a safety measure, the instrument will stop
and be placed in “Pause” mode if the screen
is touched anywhere except the “Stop” but-
ton area. This is an “Emergency Stop” fea-
ture. As described above, the count will re-
set, and the system will stop if the “Stop”
button is pressed.
Pressing the “Stop” button also erases the current
number of counts and resets the counter to zero
(in count up mode) or to cycles set (in count down
mode). A confirmation screen asks to confirm the
“Stop” and reset operation.

7 Maintenance and Repair
Cleaning and Routine Maintenance
Care should be taken to avoid letting abrasion materials spill from the pan. If
spillage occurs, clean the covers with mild soap and water as soon as practical.
If abrasive substances are spilled on the LCD display clean it with mild soap and
water. This includes a glass surface so take care not to use excessive force.
Avoid solvents on the cover and the LCD as they may be seriously damaged by
strong solvents.
Troubleshooting
If the carriage becomes jammed the instrument will stop and report an error
message. If this occurs, turn off the power, remove the power connector from
the rear of the unit and clear any visible jams. Once cleared, replace the power
connector, and turn on the instrument. If a jam is still indicated, contact your
local BYK-Gardner office for assistance.

9 Appendix
9.1 ASTM Test Setup - Part Number 5064
The ASTM brush and holder is easy to install and quite versatile. This guide is
intended to help set up the Gardner-scrub for use with the ASTM standards.
Please refer to specific standard for a complete description of the test method.
Pictured are the parts that come with the ASTM
accessory kit. On the left is the Lily Frame with two
configurable dividers, in the center from top to
bottom are the brush holder, brush, brush pad and
brass shim. On the right is the glass plate.
This photo shows the brush and holder. The holder
is attached to the Gardner-scrub by removing the
two acorn-head nuts on the brush holder. Then
slip the posts into the desired holes on the carriage
arm. Reattach the nuts to retain the brush holder
when the arm is lifted.
A single brush should be mounted in the center
holes of the arm. Multiple holes are provided to al-
low single, 2 brush or 3 brush operation. The “Lilly
Frame” can be adjusted by moving the dividers to
allow various combinations of brushes.
Up to three brushes may be used at the same time.
Additional weights of 500 and 1000 grams are
available to put extra pressure on the brush to
speed failures on tough coatings. However, these
weights fall outside of the ASTM specifications.
The weight slides onto the pins of the brush
holder.
NOTE: Additional weights may not be compatible with all brushes, test your
brush with extra weight before committing to a change in your test specifica-
tions.

9.2 ISO Test Setup - Part Number 5065
The ISO accessory kit includes an adapter and pad holder for using abrasive
pads with the Gardner-scrub. This guide is intended to help the user set up the
Gardner-scrub for use with the ISO standards. Please refer to specific standard
for a complete description of the test method.
Pictured are the parts that are included with the
ISO accessory kit. The adapter plate is shown on
the left and a single pad holder and pad are
shown on the right. Note that the adapter will ac-
commodate one, two or three pad holders at the
same time. The kit includes one pad holder. Addi-
tional pad holders may be purchased from BYK-
Gardner.
The ISO Adapter Plate must be installed on the
Carriage Arm. Four (4) screws are provided in the
kit. Once the Adapter Plate is attached it can re-
main in place. Note the hole configurations. Users
can place one, two or three pad holders on the
Gardner-scrub.
On the bottom of the pad holder are a series of
pins. These pins help hold the pad in position as
the Gardner-scrub moves. To use, lay the pad on
the sample surface and firmly press the pad holder
down on top of it. Make sure the entire pad is un-
derneath the holder. Then lower the carriage arm
onto the pad holder and start the test.

9.3 DIN Test Setup - Part Number 5066
The DIN accessory kit includes all of the additional parts needed to use the
Gardner-scrub for DIN 53778. This guide is intended to help the user set up the
Gardner-scrub for use with this DIN method. Please refer to specific standard
for a complete description of the test method.
Pictured is the DIN brush holder and brush. The
combination weighs 250 grams in the dry state as
required by the specification. Please review section
“ASTM Test Setup - Part Number 5064 [}17]” for in-
structions on the brush holder installation.
Also included is a burette and stand to meter liq-
uid into the pan during the test. The stand must
be assembled by clamping the vertical rod into the
base, then sliding the burette clamp in place and
tightening the thumbscrew. The burette then can
be filled with the appropriate solution and placed
in the clamp. Tighten the clamp with just enough
force to hold the burette securely. Do NOT over
tighten!
Position the assembly to allow the burette to drip
into the pan along the test area. Adjust the valve
of the burette to obtain the desired flow rate.
The Gardner-scrub will support up to 3 DIN brush
assemblies at one time. For additional brush hold-
ers use part number 5075. To order an additional
clamp and burette assembly use part number 5093.
