GenTaber is NextGen's Taber Abrasion Tester is widely used to evaluate wear resistance. It can conduct tests on a wide range of materials such as: cloth, paper, paint, plywood, leather, tile, glass, rubber etc. It tests the specimen by rotating it while in contact with the grinding wheel and applying the required pressure. The Loss of weight reflects on the change in weight of the specimen. The unit also comes standard with an intelligent power failure recovery function.
The test applies to material thicknesses between 6.35mm to 40mm. A flat square or round specimen of roughly 100mm is mounted on the system which rotates at a fixed speed vertically. Taber's wheels are lowered onto the material at a specific pressure. The X pattern of abrasion produced by the double rotary action allows for an accurate identification of the materials' wear and tear. The Taber abraser comes standard with a full range of auxiliary weights, specimen holders, abrasive wheels, wheel refacer and vacuum unit.

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.

The test can be used on rust-proof painting, anodizing, electroplating and rust-proof of grease. The machine imitates expedited corrosion process via salt spraying on a given test sample to identify the corrosion (oxides) resistance. Test results are based on the longevity of time a material can resist visible corrosion on the test sample.
The machine is designed to test the abrasion resistance of fabrics and metals. The abrasion of fabrics is tested when the specimen is pulled over the frame and rubbed against an abradant over a curved surface. The number of cycles, also known as double rubs, conducted on the specimen before the fabric shows visible wear is used to determine the rating of abrasion.
GenRebound tests the resilience of rubber compounds. The machine must be adjusted in a horizontal position and the plunger raised at a specific height.
