The Multi-Finger Scratch / Mar Tester includes a pneumatically driven, moveable platform to which the test specimen is mounted.  The platform moves in a linear fashion, and is operated by a control knob for single or multiple pass testing.  An electronic timer displays the rate of speed, which can be controlled by reducing or increasing air pressure.

A gantry supports five independent splined-fingers, which provide a constant, vertical load on interchangeable scratch tips.  The gantry system includes a handle to raise and lower the arms.  In addition, five support rests are incorporated to allow one or more arms to be moved to an upright, rest position such that the arm does not contact the specimen during testing.

 

Individual weights of varying loads mount to the top of each arm finger to exert a standard force on the surface of the test material. Each instrument includes a weight set of 2N, 3N, 4N, 5N, 6N, 7N, 10N, 15N and 20N loads.  Optional weights sets are also available consisting of either 4N, 8N, 9N, 12N or 8N, 13N, 18N weights.  In addition, an optional weight of 25N or Precision Weight Kit to achieve 0.6N loads are available.

Although flat specimens up to 22mm thick are normally tested, the 'free-floating' arms fingers enable you test slightly contoured specimens provided they are rigid or adequately supported.  A spring-loaded specimen holder is standard and can be mounted to the end or side of the moveable platform for greater flexibility.  To mount contoured specimens, two specimen hold-down clamps are provided.  An optional 5mm spacer set is available to raise the gantry to accommodate specimens that are greater than 22mm thick.

Taber tests involve mounting a flat specimen approximately 100mm square or round to a turntable platform that rotates on a vertical axis at a fixed speed.  The standard material thickness that can be evaluated with the Taber Rotary Abraser is 6.35 mm (materials greater than 6.35 mm but less than 40 mm can be tested with optional accessories). Two genuine Taber abrasive wheels, which are applied at a specific pressure, are lowered onto the specimen surface.

Characteristic rub-wear action is produced by contact of the test specimen against the sliding rotation of the two abrading wheels.  As the turntable rotates, the wheels are driven by the sample in opposite directions about a horizontal axis displaced tangentially from the axis of the sample.  One abrading wheel rubs the specimen outward toward the periphery and the other, inward toward the center while a vacuum system removes loose debris during the test.  The wheels traverse a complete circle on the specimen surface, revealing abrasion resistance at all angles relative to the weave or grain of the material.  The resulting abrasion marks form a pattern of crossed arcs in a circular band that cover an area approximately 30 cm2.

Each turntable has dual abrading arms that are precision balanced.  Independently operated, the abrading arms can be raised (or lowered) to mount or inspect specimens.  Each arm is precision balanced and will apply a load of 250 grams against the specimen, exclusive of the weight of the wheel.  To increase the load to 500 or 1000 grams, a mount for auxiliary weights is located on the outside of the abrading wheel bearing assembly.  This location ensures that weights are concentric with the abrading wheel.  An optional counterweight kit is available for the Model 1700/1750 to reduce the load.  For older style Taber Abrasers, a stud on the rear end of the abrading arm is used to carry an optional counterweight. All models use counterweights to reduce the load by 50, 125, 150 or 175 grams.

Taber Abrasers Model 1700 or 1750 offer the following standard features:

  • Specimen turntable speed control allows options of both 60 rpm and 72 rpm.
  • Easy-to-use LCD operator touch screen interface with selectable display options (including language selection).
  • A vacuum system is included and is critical for the proper operation of the instrument.  The direct flow vacuum nozzle is hinged to an adjustable mount at the rear of the housing. The nozzle includes two 8mm diameter orifice screw-in nozzle tips (11mm are sold separately).  A precision vacuum nozzle adjustment control allows the height to be modified for accommodating varying specimen thickness.
  • Compact abraser arm assemblies provide a standard load of 250 gram on the wheel.  Using the auxiliary weights, standard wheel loads of 500 or 1000 grams can be obtained.  Please note, the markings on the auxiliary weights are NOT reflective of the actual mass of the additional weight.  The auxiliary weights are marked with the TOTAL load that will be exerted on the wheel and equals the combined mass of the abraser arm and auxiliary weights. The weight marked 500 gram is actually 250 grams and the weight marked 1000 gram is actually 750 grams.
  • A Quick Release Mounting Hub permits quick wheel mounting without the need of a locking nut, resulting in increased clearance for the vacuum pick-up nozzle and a larger viewing area for the test specimen.  A spring loaded, beveled retaining nut provides a positive locking force on the wheel hub retaining lip making certain that the wheels remain securely fastened until disengaged.
  • Each specimen table includes an independent support frame to which the abraser arm and nozzle assemblies are affixed.

Shear / Scratch Tester 

A removable scale beam is mounted on a pivotal shaft projecting from an adjustable gage block.  An adjusting screw permits the height of the pivotal shaft to be raised or lowered, corresponding with the thickness of a test specimen up to 12.7 mm (0.5 inches).  This adjustment allows the scale beam to be maintained in a level position in respect to the specimen and turntable.  Designed with an integrated bearing, the scale beam can be tilted in a rest position enabling the operator to mount or remove specimens.

A calibrated sliding weight is mounted on the scale beam.  By changing the position of the sliding weight, the load applied by the scratch tip (shear tool) can be adjusted between 0 to 500 grams.  A second calibrated weight may be attached to the end of the scale beam, thus increasing the load capacity and changing the scale to 500 - 1000 grams. Engraved graduations are marked on the scale beam representing 10 grams per division.

Operated by an on/off switch, the motorized turntable rotates at a constant speed to ensure greater accuracy in test results.  The turntable rotates in a counter-clockwise direction, but with a simple conversion the turntable rotation can be reversed (for more information contact Taber).

For materials sensitive to scratching, an optional Scale Beam Modified Weight Set is available that converts the scale by 1/10 to 0 - 50 gram range.  To increase the testing load from 1000 to 1500g, an optional Scale Beam Fixed Weight is available.  To satisfy EN 13310 (Kitchen Sinks - Functional requirements and test methods) an optional weight that provides a 15N load is also offered.

The Taber Linear Abraser incorporates a horizontal arm that reciprocates in a linear motion.  Attached to the end of the arm is a precision bearing spline shaft that creates a 'free-floating' test system and permits vertical movement.  The test attachments are affixed to the bottom of the spline shaft and a weight support is mounted to the top.  As the horizontal arm strokes back and forth, the test system raises or lowers vertically as the test attachment follows the contours of the specimen.  A laser alignment guide assists with specimen set-up to ensures the abradant travels over the desired area.

Adjustable settings enable the user to select the speed, stroke length and test load.  The Linear Abraser includes six preset speed buttons, along with the ability to adjust the speed from 2 to 75 strokes per minute.  Eleven stroke lengths are standard ranging from 0.2 inch to 4.0 inch. 

The base load of the "free-floating" test system is 350 grams and consists of the test attachment; spline shaft; and weight support.  Three 250g weight discs are supplied with the instrument and optional weight discs ranging from 10 to 250 grams can be added to the weight support to increase the test load to approximately 2100 grams.  Optional accessories can be also be used to decrease the load.  For example, an 150mm aluminum spline shaft and plastic Wearaser Collet Kit can bring the minimum load on the sample to as low as 60 grams.  Taber's Linear Abraser is programmable to 999,999 cycles, but caution must be used as the abradant may wear prior to the end of the test.

 

The Wearaser® collet assembly is supplied with each Taber Linear Abraser, along with CS-10 and H-18 Wearaser abradants.  The size and shape of a pencil eraser, the Wearaser is made using the same high quality Taber abrasive media found in our Genuine Taber abrading wheels.  This permits the use of equivalent abrasive materials with the Linear Abraser as well as Taber's Reciprocating Abraser and the Taber Rotary Platform Abraser.

The Multi-Head Attachment (sold separately), incorporates an additional spline shaft, permitting two tests to be performed simultaneously with the Linear Abraser.

With the diversity of products that can be tested with the Taber Linear Abraser, it is up to the end-user to determine a suitable clamp or fixturing device appropriate to their product.  Click here for additional information on specimen mounting available from Taber Industries.

The Falling Sand Abrasion Tester - Model 820 is a popular apparatus used to measure the resistance to abrasion of paint, lacquers and other organic coatings.  Abrasion results from abrasive particles falling through a guide tube and impinging the test specimen, until the substrate becomes visible.


Based on a design described in ASTM D 968 and other internationally recognized test standards, the Falling Sand Abrasion Tester consists of an 8" diameter sand reservoir which includes a 60° taper funnel.  Standardized abrasive particles placed in the reservoir are released to a guide tube by an abrasive flow gate key.  The guide is a 36" straight, smooth-bore tube which contains the abrasive particles as they fall.  Specimens are fixed under the guide tube at a 45° angle in a receptacle that includes an opening at the bottom allowing the abrasive particles to be collected in a container.  A sturdy base and support system hold the apparatus in a vertical position.

The Taber® Crockmeter - Model 418 provides a quick and accurate method to determine the amount of color transferred from textile materials (such as fabric, carpeting, yarn and leather) to other surfaces by rubbing.  The Crockmeter has also been employed to perform rub abrasion, scuff and / or mar tests on flat specimens.  Plus, it can be used to conduct smudge and smear resistance tests on images produced by a printer or copier.  Regardless of specimen material, both wet and dry testing can be performed.


Originally designed to simulate the action of a human finger and forearm, the Crockmeter uses a standard pressure and rubbing motion to provide reliable and reproducible test results.  Specimens are positioned on the base of the Crockmeter and held in place with the sample holder. To prevent the specimen from shifting during testing, a sandpaper pad is provided to place under the specimen.  A hand crank moves a reciprocating arm a distance of approximately 100mm. The rubbing action is provided by a 16mm diameter acrylic "finger" which moves back and forth in a straight line with each complete turn of the crank. The reciprocating load arm is weighted to provide a constant 9N load on the sample at all times and a mechanical counter keeps track of completed cycles.
