Overview

The Finetech Engineering DIN Abrasion Tester is a rotary drum abrader designed to measure the abrasion resistance of vulcanised rubber, thermoplastic elastomers (TPE/TPR), and other elastomeric materials. Abrasion resistance is one of the most critical properties for rubber products that experience friction and wear in service — tyre treads, conveyor belt covers, shoe soles, seals, gaskets, hose covers, and industrial rollers. A compound that wears too quickly in the field costs customers money in replacement parts and downtime. The DIN abrasion test gives you a quantitative measure of how well a rubber compound resists wear, before it ever reaches the field.

The test principle is straightforward: a cylindrical rubber specimen (16 mm diameter, 6–15 mm thick) is pressed against P60 grade abrasive paper mounted on a rotating drum (150 mm diameter, 40 rpm). The specimen traverses 40 metres across the abrasive surface under a specified contact load (typically 10 N). The specimen is weighed before and after the test, and the mass loss is converted to volume loss using the specimen’s density. The result is expressed as volume loss in mm³ — lower volume loss means better abrasion resistance — or as an Abrasion Resistance Index (ARI), which compares the compound’s performance against a standard reference rubber.

This method, originally defined in DIN 53516 and now harmonised internationally as ISO 4649 and ASTM D5963, is the most widely used abrasion test for rubber worldwide. It simulates real-world frictional wear more reliably than other abrasion methods, making it the standard choice for compound development, incoming material inspection, and quality control in tyre, footwear, conveyor belt, and general rubber manufacturing.

How the DIN Abrasion Test Works

Step 1: Specimen Preparation

  • Cut a cylindrical specimen: 16 ±0.2 mm diameter, minimum 6 mm thick (typically 6–15 mm)
  • Specimens are die-cut from vulcanised rubber sheets using a round specimen cutter and hydraulic or pneumatic press
  • Alternatively, mould cylindrical specimens directly using a DIN abrasion mould
  • Condition specimens at 23°C ±2°C for at least 16 hours before testing

 

Step 2: Pre-Abrasion (Conditioning Run)

  • Mount the specimen in the holder and run a short conditioning pass over fresh abrasive paper
  • This removes the moulding skin and ensures a flat, uniform contact surface
  • Discard the conditioning mass loss — it is not part of the test result

 

Step 3: Test Run

  • Mount fresh P60 abrasive paper on the drum (or use the calibrated section)
  • Apply the specified contact load (10 N standard per ASTM D5963; 5 N or 10 N per ISO 4649)
  • Run the specimen over 40 metres of abrasive path (84 drum revolutions at 40 rpm)
  • The specimen traverses laterally 4.2 mm per drum revolution, ensuring contact with fresh abrasive surface
  • Rotating method (ISO 4649 Method B): specimen also rotates during traversal for more uniform wear
  • Non-rotating method (ISO 4649 Method A / DIN 53516): specimen holder is fixed

 

Step 4: Calculate Results

  • Weigh the specimen before and after the test — calculate mass loss (mg)
  • Convert mass loss to volume loss: Volume Loss (mm³) = Mass Loss (mg) / Density (g/cm³)
  • Calculate ARI: ARI (%) = (Volume Loss of Reference Rubber / Volume Loss of Test Rubber) × 100
  • Higher ARI = better abrasion resistance

Understanding Your Results
Metric Formula What It Means
Volume Loss (mm³) Mass Loss (mg) ÷ Density (g/cm³) The volume of rubber worn away during the test. Lower = better abrasion resistance.
Abrasion Resistance Index (ARI %) (Volume Loss of Reference ÷ Volume Loss of Test) × 100 How the test rubber compares to the standard reference rubber. Higher = better. ARI of 100% means equal to reference; >100% means better than reference.
Relative Volume Loss Volume Loss of Test ÷ Volume Loss of Reference Ratio comparison. Values <1.0 indicate better abrasion resistance than reference.

Typical volume loss values (for reference):

  • Standard reference rubber (IRB #1 or equivalent): 180–220 mg loss under 10 N / 40 m
  • Good tyre tread compound: 80–120 mm³ volume loss (ARI 150–250%)
  • Footwear sole compound: 100–200 mm³ (application-dependent)
  • Conveyor belt cover: 80–150 mm³
  • Seals and gaskets: varies widely depending on hardness and compound type
Applications
  • Tyre compound development — comparing tread compound formulations for wear resistance
  • Footwear sole testing — per EN ISO 20344 / SATRA TM174 for sole durability
  • Conveyor belt cover evaluation — selecting compounds for abrasion-intensive conveying applications

A DIN abrasion tester (also called a rotary drum abrader or DIN abrader) is a laboratory instrument that measures how well a rubber or elastomer material resists abrasive wear. A cylindrical rubber specimen is pressed against P60 sandpaper mounted on a rotating drum under a known load. After traversing a set distance (40 metres), the specimen is weighed to determine the volume of rubber lost. Lower volume loss indicates better abrasion resistance.
All three standards describe the same fundamental test method: rotary drum abrasion of rubber. DIN 53516 is the original German standard. ISO 4649 is the international harmonisation of DIN 53516, and adds a rotating specimen method (Method B) alongside the original non-rotating method (Method A). ASTM D5963 is the American version, substantially equivalent to DIN 53516 and ISO 4649 Method A. The Finetech tester complies with all three standards.
In the non-rotating method (Method A / DIN 53516 / ASTM D5963), the specimen holder is fixed and the specimen traverses the drum surface without rotating. In the rotating method (ISO 4649 Method B), the specimen also rotates during traversal, producing more uniform wear across the contact surface and reducing result variability. Most Indian labs use the non-rotating method. The rotating method is increasingly specified by international and export customers.
A cylindrical specimen, 16 mm ±0.2 mm diameter, minimum 6 mm thick (typically 6–15 mm). Specimens are either die-cut from vulcanised rubber sheets using a 16 mm round cutter and press, or directly moulded using a DIN abrasion mould. Finetech manufactures both the round cutter and the mould.
ARI is a percentage that compares your test rubber’s volume loss to that of a standard reference rubber tested on the same abrasive paper. ARI = (Reference Volume Loss / Test Volume Loss) × 100. An ARI above 100% means your compound is more abrasion-resistant than the reference. An ARI below 100% means it is less resistant. ARI is the most meaningful way to report DIN abrasion results because it eliminates variability caused by differences in abrasive paper batches.
The abrasive paper wears out during testing and becomes less aggressive over time. Most standards require that you calibrate the paper by running a standard reference rubber before and after your test specimens. Replace the paper when the reference rubber’s volume loss falls below the acceptable range (typically 180–220 mg for the standard reference under 10 N / 40 m). In practice, one sheet of abrasive paper typically lasts for 15–25 test runs before needing replacement.
DIN abrasion measures wear resistance, but a complete rubber compound evaluation also requires tensile testing (UTM with ASTM D412), tear testing (UTM with ASTM D624), hardness (Shore A/D durometer), flex crack resistance (Demattia flex tester), rebound resilience (pendulum rebound tester), and compression set (compression set apparatus). Finetech manufactures all of these instruments.
Yes. Finetech supplies P60 grade abrasive paper rolls sized for the 150 mm × 460 mm drum, and standard reference rubber compound slabs with certified volume loss values. These are the two consumables needed for every DIN abrasion test. Contact us for pricing and minimum order quantities.
The DIN abrasion test is designed primarily for vulcanised rubber and thermoplastic elastomers. It can also be used for rubber-like materials such as PU elastomers, rubber-bonded cork, and soft PVC — any material where abrasive wear resistance is a critical property. It is not suitable for rigid plastics or metals.
