Taber Abrasion Tester

Each turntable features two precision-balanced abrading arms. The abrasive arms can be independently lifted (or lowered) to mount or view specimens. Excluding the weight of the wheel, each arm is precisely balanced and will exert a load of 250 grammes upon the specimen. A mount for auxiliary weights is situated outside of the grinding wheel bearing assembly, increasing the load to 500 or 1000 grammes. Weights are guaranteed to be in a position that is concentric with the abrading wheel.

An adjustment for each material's specific gravity should be done when comparing the wear resistance of materials with various specific gravities in order to provide an accurate assessment of the comparative wear resistance. Divide the wear index result by the specific gravity of the material after computing the wear index as demonstrated above. The application of this adjustment factor yields a wear index corresponding to the material's volume loss. Test conditions, such as wheel choice and load, must be the same when comparing materials with different specific gravities.

In Taber testing, a flat specimen that is 100mm square or circular is mounted to a turntable platform that rotates at a fixed speed around a vertical axis. The Taber Rotary Abraser can measure materials with a typical thickness of 6.35 mm (materials greater than 6.35 mm but less than 40 mm can be tested with optional accessories). Particular pressure is supplied to two genuine Taber abrasive wheels as they are lowered onto the test specimen surface.

The test specimen comes into touch with the two abrading wheels as they slide around in a characteristic rub-wear action. The sample drives the wheels on the turntable in opposite directions as it revolves around a horizontal axis that is offset tangentially from the axis of the sample. During the test, a vacuum system eliminates loose material while one abrading wheel rubs the specimen outward toward the periphery and the other inward toward the core. Abrasion resistance is visible at all angles in relation to the weave or grain of the material when the wheels go around the whole circumference of the specimen surface. The resulting abrasion marks cover an area of around 30 cm2 and take the appearance of crossed arcs in a circular band.

NextGen’s Taber Abrasion Tester wheel center distance is 63.5mm.

The GenTaber Taber Abrasion Tester from NextGen is frequently used to gauge wear resistance. It can test a variety of materials, including rubber, cloth, paper, paint, plywood, leather, tile, and cloth. By rotating the specimen while it is in contact with the grinding wheel and supplying the necessary pressure, it tests the specimen. Weight loss has an impact on the specimen's weight change. Additionally, the device has an intelligent power failure recovery feature as standard.

Material thicknesses ranging from 6.35mm to 40mm are tested. A flat, 100mm-diameter square or round specimen is positioned on the apparatus, which rotates vertically at a constant speed. The material is lowered onto Taber's wheels at a particular pressure.

Testing is done on materials with thicknesses between 6.35mm and 40mm. The device is set up with a flat, 100mm-diameter square or round specimen, and it rotates vertically at a steady pace. At a specific pressure, the material is lowered onto Taber's wheels.

The rotating speed of NextGen’s Taber Abrasion Tester is 60/72 rpm.

The test specimen is subjected to two abrasive wheels with a predetermined load. An acceptable approach is used to measure the wear that was achieved after rotating the test specimen through a certain number of rotations (e.g. mass loss, volume loss, and change in optical properties).

The support disc for the test specimen must be flat and fastened to the motor shaft. No point on a 45 mm radius circle drawn on the disc's horizontal surface may move vertically more than 0.05 mm from its mean position as the disc is rotated. The disc must rotate at 72 rev/min at 60 Hz and 60 rev/min at 50 Hz, and it must have a nominal diameter of 100 mm.

Two symmetrical arms that may freely oscillate over a horizontal axis are required to support the abrasive wheels. The wheels must be attached in a way that allows for unrestricted rotation, such as with ball bearings. The mounting bosses must be coaxial and placed in the test position so that their vertical projection into the plane of the test specimen support disc is 19,1 mm 0,1 mm from a parallel line passing through the axis of the disc.

The ISO 7784-2 standard describes a technique for assessing coatings' resistance to abrasion in which the coating of a rotating test specimen is affected by two loaded, freely rotatable, but eccentrically positioned abrasive rubber wheels.

The following sections make up ISO 7784's general title, Paints and Varnishes. — Determining abrasion resistance:

— Part 1: A method using spinning test specimens and wheels covered in abrasive paper

— Part 2: Method using rotating test specimens and rough rubber wheels

— Part 3: A technique using a wheel covered with abrasive paper and a linearly reciprocating test specimen

The revolving test specimen's coating is pressed against by two predetermined, pivot-mounted abrasive rubber wheels while being subjected to the predetermined test load. A ring-shaped zone experiences crosswise abrasive wear due to the eccentric arrangement of the abrasive wheel axes in relation to the axis of rotation. After the agreed-upon number of cycles, the amount of mass lost by abrasive wear in the coating is calculated.

The Taber abrader is a tool that can be used to evaluate coated materials' resistance to abrasive wear, according to ISO 5470.

A central threaded rod with a nut and washer secures the test component to the turntable. The samples can be secured on rigid support cardboard for measuring thin test pieces using a double-sided adhesive tape of the proper size. The testing machine's test piece holder can be clamped onto the test piece attached to the cardboard or a solid board that serves as a close substitute, and the test piece can be removed without difficulty for weighing. About 25 mm are vertically spaced between the hinged arms' pivot points' centres and the turntable's surface.

The driving shaft must be attached to the turntable, which must be flat. No point on a 45 mm radius circle drawn on the turntable's horizontal surface may move vertically more than 0.05 mm from its mean position while the turntable is rotated. The turntable must have a nominal diameter of 100 mm and rotate at 72 rev/min when powered by a 60 Hz supply and 60 rev/min when powered by a 50 Hz supply.

Using the Taber Abraser, ASTM F1978 is a Standard Test Method for Evaluating the Abrasion Resistance of Metallic Thermal Spray Coatings.

The abrasion resistance of metallic coatings applied to flat metallic surfaces using thermal spray techniques is measured using this test method. It serves as a method of classifying coatings applied to surgical implants. It makes use of the Taber Abraser, which produces rolling and rubbing in order to wear down the coated surface. Mass loss over time is used to measure wear. Up to 100 cycles of six samples are typically used in a test.

The test setup's adaptability allows for the investigation of additional materials like decking, coatings, and films.

This test method is only applicable to flat, stiff samples that don't significantly react with water and don't go through a phase change or chemical reaction between ambient temperature and 100°C in air.

The values given in SI units should be taken as being of a standard. This standard does not include any additional units of measurement.

The Taber abraser is used in ASTM D4060 to test the abrasion resistance of organic coatings. Accelerated wear testing was first carried out using this type of test procedure in the 1930s. The gadget was widely used for a variety of test procedures and standards on a wide range of items all over the world, thanks to its simplicity and efficacy.

Mounting a flat specimen to a turntable that rotates horizontally at a set speed is required for ASTM D4060 testing. Then, two arms holding individual abrasive wheels are lowered until each wheel makes contact with the ground. A "suction arm" is lowered between the wheels to remove the abrasive material from the sample's surface before the test begins. After that, the turntable rotates, forcing the wheels to rub against the sample's surface for the predetermined number of cycles until a predetermined mass of coating has been lost or until the wheels begin to reveal the substrate.

The American Society of Testing and Materials (ASTM) developed the ASTM D3884 test standard to quantify a coated fabric's resistance to abrasion using the rotary platform method and two abraders. When evaluating the toughness and probable longevity of textiles for upholstery use, abrasion resistance testing is one of the numerous factors used.

A test specimen is mounted flatly on a platform in the shape of a turntable as part of the testing process. Each of the two weighted abrader wheels is lowered until it makes contact with the specimen's surface. The abrader wheels are made to roll over the specimen's surface because the turntable and specimen are both configured to rotate at a predetermined speed.

The rotary platform abrader test won't always show a difference that is known to exist when the materials are actually used, as different fabrics (that is, of different fibres, weights, etc.) are compared. Therefore, to at least serve as a reference for future testing of these materials, end-use experiments should be carried out in conjunction with the abrasion test.

A test to identify a plastic's abrasion resistance is called a Taber abrasion. The ability of a substance to endure mechanical action, such as rubbing, scraping, or eroding, is known as resistance to abrasion. Although haze variation or weight loss are frequently assessed, abrasion can be challenging to compare.

Test procedure: The test specimen's original weight or haze is determined. Next, the test object is set down on the abrasion tester. The abrader wheel is loaded with a 250, 500, or 1000-gram weight and allowed to spin for a certain number of revolutions. There are different abrading wheels listed. The final weight or haze measurement is obtained. For softer and harder materials, the load and wheel can be modified.

Specimen size:

4-inch diameter disk or four sq.-inch plate

A ¼ inch-diameter hole in the center is required.

What are the recommended grinding wheels to be used according to the ASTM D4060 standard?

Following the most common methods used for Taber Abrasion Test result evaluation:

Cycles to Specific End-Points – The number of necessary cycles to achieve a pre-determined end point, or the condition or appearance of the test specimen after a given number of cycles.

The criteria for evaluation may include, yarn breakage, loss in breaking strength, loss in coating, color loss, change in gloss, or other changes in terms of appearance. When inspecting the changes in the appearance in the test specimen visually, the assessments must be made using a rating system that has been previously agreed upon like a visual grading scale (5 steps, for example) or pass / fail criteria.

Taber Wear Index – This technique indicates the rate of wear. It is computed by measuring the weight loss in milligrams per 1000 abrasion cycles. The lower the number indicated in the wear index gets, the better the resistance to abrasion is.

Mass or Weight Loss – This particular method determines the amount of material that has been eaten away by abrasion. It is typically expressed in milligrams.

Volume Loss – To compare the wear resistance among materials that have varying specific gravities, corrections for each material’s specific gravity must be done to come up with a more accurate measurement of the comparative resistance to wear.

The wear index must be calculated, after which it must be divided by the specific gravity of the material. Using the correction factor gives a wear index that is related to the volume loss in the material to which the assessment is applied. To compare materials with varying specific gravities, you must use the same test parameters including the selection of load and wheel.

Wear Cycles/Mil (0.001 of an inch) – This method is used when expressing abrasion cycles necessary to wear through a coat of a given thickness.

Depth of Wear – When measuring the depth of wear, it is best to utilize a thickness gauge or any other appropriate device to determine the thickness of the specimen on 4 points along the path intended to be abraded, around 38mm measured from the center hole, with the points approximately 900 apart. Compute the average reading.

Once the specimen has undergone abrasion, do the measurements again, then get the average of the readings. Compute for the difference. As an alternative, you can measure the depth of the wear using an instrument like an Optical Micrometer or something similar.

Residual Breaking Force (fabric materials) – This method is used to measure the fabric’s effective strength or the force needed to break a fabric’s specific width. To determine the abraded specimen’s individual breaking force, you can use the procedure provided in the ASTM D5035 and D5034 Standard Testing Method for Breaking Strength & Elongation of Textile Fabrics.

It is worth mentioning that you need to adjust the referenced distance between the clamps to 25 mm, and then horizontally position the abrasion path on the abraded specimen at the midway point between the clamps. The breaking point must be reported to the nearest 0.5 kg.

Average Breaking Strength (fabric materials) – This is measured by getting the average of the abraded specimens’ breaking strength and the unabraded test specimens, as measured using the Residual Breaking Force technique.

Breaking Strength Percentage Loss (fabric materials) – To measure the original fabric’s breaking point and the abraded test specimen, you can use the method cited above (ASTM D5035 and D5034). Compute the breaking strength percentage loss rounded to the nearest 1% for all the widthwise and lengthwise directions.

Every turntable has a pair of precision balanced abrading arms, each one operating independently. The abrading arms may be lowered or raised when mounting or inspecting the specimens. Each of the arms is precision balanced, and capable of loading 250g against the test specimen, not counting the wheel’s weight.

To raise the load to 500g or 1000g, a mount specifically for auxiliary weights is positioned along the outside of the bearing assembly of the abrading wheel. The location guarantees that the abrading wheel is concentric with the weights.

The contact between the test specimen and the two abrading wheels' sliding rotation produces the characteristic rub-wear action. While the turntable rotates in one direction, the sample drives the wheels in the opposite direction, around a horizontal axis that is tangentially displaced from the sample's axis.

One of the abrading wheels rubs the test specimen outward, in the direction of the periphery. The other goes inward to the center. Meanwhile, a vacuum system gets rid of the loose debris from the test. The wheels pass through a complete circle over the surface of the specimen. It reveals the abrasion resistance from all angles in relation to the material's grain or weave. The abrasion marks that result from the process form a crossed arc pattern in a circular band, and covers an approximate area of 30 sq. cm.

The Taber Abrasion Tester is used for testing a wide array of materials, and has been referenced in multiple standards and specifications. These include coatings, plastics, leather, laminates, ceramics, paper, safety glazing, and carpeting, among many others.

The results are shown by the changes in haze percentage or weight loss in mg/number of cycles.

Ideal specimen size is a 4 in. diameter disk or a 4 sq. in. plate.
A ¼ in. diameter hole at the center is necessary for the test.

The original weight or haze of the test specimen is measured. It is then loaded on the abrasion tester. A load (may be 250 g, 500 g, or 1000 g) is positioned at the top of the abrader wheel. The wheel is then made to spin for a given number of revolutions. Various abrading wheels are specified. The final weight or haze measurement is taken. The wheel and load can be adjusted, depending on the hardness of the material.

Taber abrasion is a type of test that is intended to measure a plastic's ability to resist abrasion. Abrasion resistance, on the other hand, is a material's ability to endure mechanical action like scraping, erosion, or rubbing. Comparing abrasion is often difficult. Thus, weight loss or haze variation are typically evaluated, instead.
