Most flexible materials can be cut to size using the
Model 5000
– Taber Sample Cutter
. Manually
operated, this bench top cutter uses an industrial
cutting blade to prepare a 107 mm diameter
specimen. A punch lever evenly transfers force
through a spring-loaded clutch to punch a 6.5 mm
center hole.
When it is desired to use abrasion test samples for
tests of other destructive agents such as
laundering, dry cleaning, and light fastness, it is
recommended the specimens be cut square rather
than round. The larger area of the square provides
for shrinkage in subsequent tests and permits
handling without touching the area to be abraded.
For textile materials, fold the sample twice and use
scissors to cut a small portion of the resulting corner
for the center hole.
NOTE:
To mount textiles or other flexible specimens,
place the test specimen on the holder with the side to be
abraded facing up. Lightly secure the clamp plate and nut
in place. Adjust the hold-down ring so it is a snug fit, and
place it half way on the specimen holder. Draw the
specimen taut over the specimen holder by pulling on
corners and edges. Tighten the clamp ring further, and
push the ring all the way down over the edge of the holder,
thus putting tension on the specimen as it is secured on
holder. Finish tightening the clamp plate and nut, and
finally tighten the hold-down ring. Avoid tightening to
excess so as not to wrinkle the specimen. Trim off any
excess material around the edges.
WARNING:
To prevent damage to the instrument,
avoid excess specimen material that extends
beyond the specimen hold-down ring and will rub
on the abraser housing. Trim excess material or
use tape to secure to the specimen holder. Taber
offers Model SH-
12 “Tall” Specimen Holder
(#135920) to accommodate 135 mm diameter
specimens.
NOTE:
To prevent the vacuum from lifting the specimen,
it is advised to use the hold-down ring.
NOTE:
The SH-101 hold-down ring will accommodate
flexible materials up to 0.8 mm thick. The optional SH-102
hold-down ring will accommodate flexible materials up to
1.6 mm thick.
NOTE:
Optional Textile Specimen Holder (SH-15) has a
raised wear track to give the fabric extra tension when the
hold-down ring is drawn down over the edge of the holder
and the clamp plate is secured
NOTE:
To prevent stretching or wrinkling of the specimen
during testing, flexible materials can be mounted to the S-
36 or S-36-1 Mounting Card.
Specimen Cleaning
The specimen surface must be free from
fingerprints or other contaminants. If necessary,
use an appropriate cleaning method for the material
being tested.
Specimen Conditioning
Prior to testing, it is recommended that specimens
be conditioned for at least 24 hours in a standard
laboratory atmosphere of 23 °C ± 2 °C (73.4 °F ±
3.6 °F) with 50 ± 5% relative humidity. For materials
that are susceptible to environmental influences,
tests should be conducted in the same test
atmosphere.
