| Gardner-scrub Abrasion Tester |
| Compliant with ASTM, DIN and ISO methods with appropriate accessories |
 |
Coated and uncoated surfaces need to be tested for resistance to
abrasion caused by a brush, sponge, scouring pad, sand paper,
and other means. Abrasion resistance can be tested by wet abrasion
methods using scrub media or cleaning solutions.
The most
common applications are testing the scrub resistance of interior
wall paints, floor tiles, shower stalls, and furniture surfaces.
The abrasion tester can examine the washability of a coated surface
for the removal of stains. Detergents and cleaning solutions
can be tested and evaluated in a reproducible manner. |
Features
|
 |
| The Gardner-scrub abrasion tester offers a versatile design for
abrasion and washability testing applications. The instrument arm
is designed to hold from 1 - 3 brush holders or ISO pad holders. A
large selection of accessories are available to customize your test
requirements. An intuitive touch screen operation makes it easy
to change test parameters. The Gardner-scrub has a durable chain
drive mechanism for long-term reliable operation. |
- Reciprocating linear motion with a constant speed over the travel distance for repeatable results
- Compact design saves on counter space
- Easy to use touch screen display
- Instrument arm holds up to 3 brush or pad holders to increase output
- User selectable scrub rate from 6 - 60 cycle/minute
- Compliant with ASTM, DIN, and ISO methods with appropriate accessories
- Up to 4 kg (8.8 lbs) can be applied to the instrument arm
- Adjustable stroke length 22.9 - 27.9 cm (9 - 11 in.)
- Optional weights for custom applications

ASTM Methods
|
|
ASTM D2486 - The scrub resistance of interior wall paint is the
primary purpose of this method. The paint is applied to a black
plastic panel and allowed to cure. The panel is scrubbed with a
nylon bristle brush until failure occurs. An abrasive scrub media is
used to accelerate the test.
ASTM D3450 - This test method determines the ease of removing
soilant discoloration from interior coatings. The coating is drawndown
on a black plastic panel and allowed to dry for seven days. A
specified soilant medium is applied. The coating is scrubbed with
an abrasive or non-abrasive media using a cellulosic type sponge
for 100 cycles. The soilant removal is assessed by measuring the
CIE Y standard tristimulus value before and after the test.
ASTM D4213 - The purpose of this method is to measure scrub
resistance. The primary differences from ASTM D2486 method
are: The scrub resistance is determined by weight loss of the paint
fiim relative to a standard calibration panel. The test panel and
calibration panel are scrubbed simultaneously. The scrubbing
device is a Scotch-Brite™ 7448 abrasive pad.
ASTM D4828 - This test method determines the relative ease of
removing soil and stains from interior coatings. The coating is
applied to a black plastic panel and dried for seven days, The
soilant can be user defined or the soilant described in ASTM D3450 can also be used. A user defined liquid or powder cleaner
is applied. The panel is scrubbed 100 cycles with a sponge. The
soilant removal is assessed using gloss or color measurement.
ECE 43 Wiper Resistance Test - ln specific applications it is necessary to adapt a test method to the
typical stresses during its real-world use. The wiper resistance test
was developed to simulate accelerated abrasion by automotive
windshield wipers under controlled laboratory conditions. lnstead
of rotating abrasive wheels, a linear back and forth motion of
a wiper blade is applied to the sample under test. The test
specimen is placed in a box filled with a defined suspension
according to ISO 12-103-1 A4 at ambient temperature. |
