Hold Down Bracket

When there was a need to have the test specimen stay in position while performing tests, often times tape would be used. Taping for every test can get time consuming and tedious. As a result the hold down bracket was designed. This bracket allows the user to simply turn two wing nuts to secure or release the test specimen. This item comes standard with all new machines. We offer this item as an aftermarket item for those who would like this convenience. The item is easily installed and functional after installation. Refer to the instruction section for the installation. Pictured is the hold down clip installed on a machine.

Optional Heated Weight

Designed for use with the
SUTHERLAND® Rub Tester

This heated weight provides a uniform test for evaluating the "hot abrasion" resistance of printed cartons, labels, and periodicals. Where required, rub resistance specifications may now be based on number of strokes at a given temperature as well as pressure. Before putting the weight into service, replace the natural black rubber pads on the SUTHERLAND® Rub Tester base with the silicone pad furnished. Peel the cover from the adhesive and apply the pad directly to the clean base.

The lamp in the end of the heat shield functions with the contacts in the thermostat. "Templesticks" or a pyrometer may be used to occasionally check temperature control knob settings.

When using the weight, have trichloroethylene or similar fireproof solvent and toweling handing for removing foreign material from the heated shoe between tests.

The silicone pad pictured must be used with the heated weight.

SUGGESTED PROCEDURE FOR TESTING FOR "Hot Abrasion" Resistance

Test each sample at 200°F, 300°F, 400°F and with 10 and 20 rubs at each temperature.

Start the machine oscillating at once after placing the heated weight on the sample and remove the weight immediately after oscillation ceases.

The tested specimens may be rated for wear and smear using a scale of "none, very slight, moderate, and severe".

Consideration must be given to the time interval between printing and testing, as well as to the cleanliness of the surface of the sample.

This procedure does not purport to address safety problems, if any, with its use. It is the responsibility of the user to establish appropriate safety and health practices.

Optional Weights

Pictured are several optional weights offered for the SUTHERLAND® Rub Tester. Each weight would be used for different intensities of testing. Because we specialize in this test equipment, various other weights can be requested; such as kilogram weights. Weights that are not listed are considered special orders and will require additional lead time.

1 pound weight

1/2 pound weight

1/4 pound weight

New Rubber Pads

The pads should be changed when they become hard or damaged from age and use. Recommendation is a six (6) month minimum. These can be ordered from DANILEE COMPANY. To replace pads, clean metal surface with solvent such as naphtha. Remove protective back from pressure-sensitive surface. Press this surface to the metal in the proper location.

Old Style - 5 Pads – Part #1/OSP

New Style - 3 Pads – Part # 1/NSP

Old Style Pads

Each set of "old style" pads comes with a base pad (2 5/8" x 6") and four (4) small pads
(1" x 2"). The large pad fits the base at the end of the arm. The small pads are placed at each end on the bottom of the two and four pound weights. Pads should be changed a minimum of every six (6) months.

New Style Pads

Each set of "new style" pads comes with a base pad (2 5/8" x 6") and two (2) small pads
(2" x 4"). The large pad fits the base at the end of the arm. The small pads are placed on the bottom of the two and four pound weights. Pads should be changed a minimum of every six (6) months.

A Comparison

Both styles of pads are stock items. In 1990 ASTM determined that the new style pad with its complete coverage of the weight provided more consistent and reliable results.
Note: if changing from "old style" pads to the "new style" pads, new test procedures may be

required as the "new style" pads require more rubs to achieve the same results as the "old style" pads. The reason for this is that the "new style" pads decreases the PSI (pounds per square inch) as the weight is being spread over a larger contact area.

Silicone Pad

The silicone pad pictured should be used with the heated weight. The pad may also be used for specific tests requiring a firmer substrate foundation.
