DIN Abrasion Tester

GenDIN presses the specimen against the drum at one of three loads: 2.5 N, 5 N or 10 N, with the 10 N load held to ±0.2 N. The load is set with weights attached to the chuck that holds the specimen.

Which load you use comes from the method you report to. In our operation manual 10 N is the starting point, and for compounds with low abrasion resistance the force is reduced to 5 N. The chosen method is then stated in the test report, so results run at different loads are never mixed up.

Additional 10 N loading weights can be ordered with the machine or later. Our ASTM D5963 page explains how the drum method reports volume loss and the abrasion resistance index.

If you are not certain which load your customer specification calls for, send us the document and we will check it against the machine setup.

The drum turns at 40 ±1 rpm, which our operation manual gives as a surface speed of about 0.32 m/s at the abrasive sheet.

Speed is held steady because the method measures wear over a fixed travel. The specimen holder moves across the drum in step with its rotation, so every test piece follows the same path over the abrasive, and the mass loss from one batch can be compared with the next.

GenDIN has one drum speed, and the same 40 rpm setting serves every standard listed for the machine, from ISO 4649 and ASTM D5963 to DIN 53516, EN ISO 20344 and SATRA TM174. A compound lab and a footwear lab run on the same drive.

The digital display counts the rotations during the run, so progress can be followed without stopping the test.

The GenDin - DIN Abrasion Tester uses an emery cloth with specific characteristics that are necessary for standardized abrasion testing. The emery cloth has a grit size of 60#, which is coarse enough to simulate the abrasive wear that rubber and elastomer materials would encounter in practical applications. The physical dimensions of the emery cloth are also specified, with a width of 425 mm and a length of 473 ±1.5 mm. These dimensions guarantee that the abrasive surface covers the rotating drum uniformly, providing consistent and repeatable contact with the test specimen.

The specific grit size and dimensions of the emery cloth are crucial for maintaining the integrity of the abrasion test, making sure that the wear on the test specimen is uniform and accurately reflects real-world conditions. This standardization allows manufacturers to rely on the test results for evaluating the durability and wear resistance of their materials, which is vital in industries.

The set rotation is 84 drum rotations, which corresponds to the standard abrasion travel of about 40 m. Once started, the test runs to that count and stops by itself, so every specimen in a batch sees the same travel.

For compounds with low abrasion resistance, our operation manual allows shorter runs of 42 or 21 rotations, equal to 20 m or 10 m of travel. The measured wear is then multiplied by 2 or 4 to bring it back to the full-run basis, and the shortened method is stated in the report.

The same 84-rotation run is used for the standard rubber check that verifies the abrasive sheet before samples are tested, so the reference result and the sample results are measured over the same distance.

The primary purpose of the GenDin - DIN Abrasion Tester is to measure the abrasion resistance of rubber and elastomer materials. This instrument simulates materials' wear and tear during actual use, providing precise data on their durability.

The limit rotation on GenDIN is 85 rotations, one rotation above the set value of 84 that defines the standard 40 m run. Both values are part of the machine specification, and the set value is the count the test is run to.

The digital display counts drum rotations throughout the test, and the machine stops on its own when the run is complete, so the operator does not need to time or stop the test by hand.

If the machine does not start when the Test button is pressed, the troubleshooting table in our manual points to the motor connection and the wiring of the Test button. Our technical support team can work through it with you and arrange a repair where one is needed.

The rotating drum is 150 mm (5.9″) in diameter, held to ±0.2 mm according to our operation manual, and 460 mm long. The abrasive sheet wraps around it, so the diameter fixes the travel per rotation and keeps the test length tied to the rotation count.

Fitting the sheet correctly matters as much as the drum itself. The manual calls for three strips of double-sided heat-resistant tape applied evenly along the drum, parallel to its axis, with the sheet mounted so its direction arrow faces the rear of the machine.

The edges must be aligned and parallel to the axis, and the joint gap kept under 2 mm with no overlap. After a new sheet is fitted, the drum is run once or twice with a metal block and no load to condition the abrasive surface before the reference check.

The two standards work at different levels. EN ISO 20344 is a collection of test methods for footwear designed as personal protective equipment, covering complete footwear and its components, while ISO 4649 is a single laboratory method for the abrasion resistance of vulcanized and thermoplastic rubber on a rotating cylindrical drum.

ISO 4649 defines two procedures, Method A with a non-rotating test piece and Method B with a rotating one, and reports results as relative volume loss or as an abrasion resistance index. The current edition is ISO 4649:2024, though older citations such as ISO 4649:2017 still appear in customer documents.

EN ISO 20344 includes an abrasion test for outsole materials that uses the same drum principle, alongside many other footwear tests. It sets out how to run the tests, while pass and fail limits come from separate requirement standards or the purchase specification.

GenDIN is listed for both, so a footwear lab and a rubber compound lab can run their drum abrasion work on the same machine.

The GenDin - DIN Abrasion Tester is a certified testing instrument that conforms to internationally recognized standards such as ASTM D5963 and ISO 4649.

A wide variety of industries use DIN abrasion methods for testing their products. These include the following industries and sectors: leather, textile, clothing, automotive, rubber, aerospace, rubber rollers, bearings and seals, R & D facilities, and rubber and plastic manufacturers, among many others.

Typically, these industries break into sub-industries that range from small, medium, to large-sized companies. Many of them use the DIN abrasion testing methods on a consistent basis as part of their quality control measures.

Depending on the application, the results of DIN abrasion testing are quite useful. In particular these are beneficial to manufacturers and designers of rubber products. Rubber abrasion tests are good indicators of the performance and quality of the material.

For designers, the data culled from the results can provide much help in their research efforts. Likewise, they can use the information for checking for the efficiency of the product. On the other hand, manufacturers can make use of the results to help develop better and higher quality products. finally, end-users get the assurance that the products they will use are made from superior and high quality materials.

Three test pieces are cut from various positions of the material with a diameter of about 16 mm with a + or - 0.2 mm allowance and thickness of about 6.0 - 10 mm using a tubular drill.

The piece of test specimen must be parallel to the bottom and top. The round of flank must be vertical to either side, which is in the column's shape.

Note: if the test piece thickness is less than 6.0 mm, another rubber test piece with a hardness of 65 HA must be taken in a similar way, and sticks to the test piece using universal glue. This is to guarantee the thickness of a minimum of 6 mm.

The number of test pieces must be at least 3 pieces taken from each type of material. Instrumental correction: After testing for 10 times, the instrument must be corrected using a standard rubber. It should be done in accordance to the following:

First, a standard rubber must be tested for three times. Its mean is indicated as S. The results are correct when the standard rubber wear mean is around 200 + or - 20 mg. If the results read more than 220 mg, it means that the sandpaper is too sharp and it needs to be readjusted.

Put the iron of the same size as the test specimen, then rub the rubber until it becomes less than 220 mg in size. If it achieves a size of under 180 mg after wearing, the sandpaper needs to be replaced because apparently, it is a bit too blunt.

Note: if the wears in the test piece have a variance of over 15 mg, then the specimen must be abandoned, and retesting must be done.

In general, these two methods of abrasion testing require similar specifications for the DIN abrader. However, the most obvious difference between the two is that ISO 4649 cites two methods for abrasion test - rotating or non-rotating. On the other hand, DIN 53516 doesn't have any clear requirements for the same. But, the two standards are capable of determining abrasion resistance in rubber.

Based on industry standards, the ideal sandpaper for use on the rotary drum is around 60#. The abrasive is rather coarse, and will result to a high volumetric loss.

When looking at the results of abrasion tests, it is very important to remember one thing: the higher figures are indications of a greater surface rubber loss. The higher the figure, the bigger the loss. This means that resistance to abrasion is lower. On the other hand, a lower figure is an indication of better resistance to wear.

A single belt that has good abrasion resistance can usually perform much longer and more efficiently than say, 2 or even 3 "economy" belts of lower grade or quality.

Following is the detailed procedure for DIN abrader testing.

1. First, the abrasion sheet's abrasiveness is determined. Once it is done, the device is now ready for testing. The test samples can be drilled easily on the rubber sheet or the final product using the circular cutting knife, which is optional. Usually, the tests are done at an ambient temperature of 230 C + or - 50 C with the option to heat the drum at a higher temperature.
2. The test specimen's weight is initially measured.
3. The sample is next mounted onto the sample holder. Set the preferred abrasion distance and apply the load weights. The cover of the instrument is then put in place. The testing procedure commences by simply clicking on the tester's start button.
   The drum will then begin to rotate, and the test specimen will be sent over the abrasion sheet. The moment the pre-determined abrasion distance is hit, the instrument will automatically stop running.
4. At the conclusion of the test run, the sample is taken out of the sample holder, then the weight of the test sample after the abrasion process is measured.
5. Calculate the abrasion. To do this, convert the mass loss (with average value of 3 - 10 individual values) into volume loss with the aid of the density and the correction done for the abrasion sheet's abrasiveness deviation from the given value of abrasiveness.

The following formula is used:

Abrasion = mass loss x abrasiveness x 200 specific weight

Rubber is a very elastic and versatile material. It is the material of choice in production verticals because of the different properties it has. The material is used to manufacture industrial products, domestic products, toys, and accessories, among others.

Rubber comes from the rubber plant. However, the rubber material taken from plants is quite soft by nature, and is not suitable for use in industrial applications. It cannot be molded into different shapes and sizes. The rubber material is hardened through the vulcanization process.

This is where abrasion testing comes in. The produced rubber material is tested to make sure it is durable enough for use as a material for manufacturing various products.

Abrasion testing is performed on materials that abrade or wear off over time. Some examples of these materials are belts, tires, shoe soles, and conveyor belts, among others.

In a DIN abrasion test, the specimen is secured into a sample holder (quick clamp), and then guided in a precise manner, with or without rotation, over a predetermined distance of either 20 m or 40 m. There is also a given load on a piece of abrasive paper that is mounted to a 150 mm diameter stainless steel rotary drum. The drum turns at a speed of around 40 rpm. Ultimately, the frictional loss is computed by comparing the weight of the test specimen before and after the test.

The rotary drum-type DIN abrasion tester performs test in compliance with DIN ISO 4649, D53516, ASTM D 5963, and AS1683.21.
