A Complete Guide to ASTM D4966 ISO 12947 Martindale Abrasion Test Method

The abrasion resistance of fabrics is a key testing parameter in the textile industry laboratories. As a lab technician, understanding the operational steps of the abrasion resistance testing instrument is essential for daily tasks. This article will take you through the detailed steps of using the Martindale Abrasion Tester for Martindale abrasion testing.

Martindale Abrasion Test Principle

Under certain pressure, circular fabric samples undergo reciprocal friction with a standard abrasive along the Lissajous curve, leading to sample damage. The number of abrasion cycles, until sample damage occurs, represents the fabric’s abrasion resistance.

Martindale Abrasion Resistance Test Procedure

Turn on the instrument power switch. Tap the touchscreen, and you will see the standby interface. You can choose your language. Next, enter the function menu interface. As shown in the figure below. Here, you can set the buzzer reminder time for the end and set the counting method, and speed.

Overall Setting

You can set the number of laps required for each station individually or collectively. The reset button can initialize the lap count. The delete key can clear the station setting data. Press the start button to start counting according to the set number of laps. There will be a buzzer prompt after the station is completed. If you continue the test, you need to restart the instrument.

Prepare standard abrasives, standard padding, and samples according to the standard method.

Cover the standard abrasives on the standard padding. The surface of the standard abrasives should be free of wrinkles, knots, or uneven thickness. Place a sample pressure hammer on the standard abrasives, and then tighten the abrasive tight ring to fix it on the sample table. You need to ensure that the nine abrasives are under the same tension. Each time the test starts, new standard abrasives or samples must be used. After 50,000 friction cycles, even if the test is not over, new standard abrasives must be replaced.

Place the sample on the friction head required by the method standard, and at the same time, pad polyurethane foam plastic between the sample and the friction head.

Put the rubbing head on the abradant material and thread the connecting rod through the hole of the guide apron onto the rubbing head. Whether a weight for a sample or hammer is needed depends on different test methods. 

After setting the right Lissajous motion curve specification, touch the Start key to start up the instrument. The instrument will stop automatically when the number comes to 0.

Check the abrasion grade of each sample and evaluate the required interval speed if continuing the test. According to the above setting method, reset the interval speed on the setting display window and restart the instrument. If some of the 9 samples have finished the test, touch the relevant work position number window to lock its counting function and disassemble the rubbing head of this work position. Then continue the test of other samples till all 9 samples have finished their tests.

Record the accumulating rubbing data of each work position.

If going on the next test, touch the Reset key to make the instrument back to its initial state so that the estimated rubbing speed can be reset.
