If you need to test the rubber abrasion resistance index with precise calculation, let us introduce the experiment.
DIN Abrasion Test Method
To determine the abrasion resistance of rubber, PTR, plastics.
Sole materials, eg. rubber, PTC and plastics.
1)DIN Abrasion Test
Holder Moving distance: 4.2±0.04mm each rotation
Roll Dim.: Dia. 150 x Length 460mm
Rotation speed: 40±1rpm
Clamp holder speed: While the rotary drum spins 50rpm, the clamp holder spins 1rpm.
Angle: 3°(the angle between test piece support and vertical plane of roller)
2)Tubular drill (diameter: 16±0.2mm)
3)Small electric drill with vertically adjustable drill bit
4)Standard rubber test piece (meets with DIN53516 standards)
5)Universal glue (suits to adhere with test piece of rubber and plastics)
6)#60 Sandpaper (meets with DIN53516 standards)
7)Electronic balance (corrects to 0.0001g)
9)Shore hardness tester (SHORE A)
Test piece preparation:
Three test piece are cut from different positions of material with diameter of 16±0.2mm and thickness of 6.0~10mm by tubular drill. The test piece is parallel to the top and bottom, and
the round of flank must vertical to both sides, which in the shape of the column. (Attention: If the thickness of test piece is less than 6.0mm, other test piece of rubber with hardness of 65HA should be taken in the same way, and adheres to test piece to ensure the thickness up to at least 6mm by universal glue. )
Number of test piece: at least 3 pieces of each material
Instrumental correction: After 10 times of test, it should be corrected by a standard rubber in the following way. At first, a standard rubber should be tested in 3 times, and indicate its mean as S. It is correct that when the mean of standard rubber wear is about 200±20mg. If its wears over 220mg, it means sandpaper is so sharp that need to be readjusted. Putting the iron as the same size in test piece, and the standard rubber should be rubbed until it less than 220mg. If its wears less than 180mg, the sandpaper need to be changed because it is too blunt. (Attention: If the test piece wears have a difference more than 15mg, it should be abandoned and retested)
1)According to the method of measuring the proportion of materials, we measure the proportion of materials which is indicated as Q.
2)Adding 250g and 500g weight to the upper end of the fixed column,we must make sure that the total weight of the fixed column is 1kg (specimen clamp itself weighs 250g)
3)The specimen should be cleaned with soft bristles, in order to keep any dirt away, please wipe the burrs with fingers.
4)Using electronic scales to weigh the specimen, the numerical value should be accurate to 0.001g, which is indicated as W1.
5)Clean the dirt left by previous two test with the soft bristles.
6)Fix the test piece, and the surface of the specimen should be parallel to the bottom of the stationary column. And then turn the knob anticlockwise for two revolutions, which make the surface of the specimen can be higher than the column head 2.0±0.2mm.
During the testing process, if the test piece is expected to wear poorly, the machine has to stop halfway when the wears may exceed 2mm, and we should pull out the specimen 2mm so that we can continue the test.
7)Lower the column head and place on the starting point of the drum wheel, and then start the machine and vacuum cleaner. Let the specimen be worn on the drum wheel at from the starting point to terminal point, which whole distance is 40m.
8)Remove the specimen from the column head, wipe the adhesive fragment with our finger and remove dirt and debris with the soft brush.
9)Weigh the specimen again and the numerical value should be accurate to 0.001g, which is indicated as W2.
In the equation:
A: Wear volume of rubber, mm3
W1: the weight before wear of rubber test piece, mg
W2: the weight after wear of rubber test piece, mg
Q: Density of rubber test piece, mg/mm3
S: Wear of Standard rubber test piece, mg
To calculate and indicate the mean of three test results, which should be corrected to millimeter.

Q: Does the sand paper need to be replaced after each measurement?
A: It is normal that a loss between 180mg and 220mg is in mass in each abrasion. If the loss is less than 180mg, the sand paper should be replaced. If the loss is over 220mg, metal sheet should be used to polish the sand paper.
