Taber Abrasion Tester

Purpose and Application
Resistance to abrasion is one of the most significant mechanical properties of any surface. The use of the TABER® ABRASER is counted among the most commonly used and best-known methods for testing durability and resistance to wear. In numerous national and international standards specific reference is made to this test equipment.
 
The Original TABER® ABRASER enables abrasion testing to be conducted on paint and other coatings such as rubber, paper, leather, ceramics, textile surface structures and metals. The equipment is suitable for use in research and development and for in-process and quality assurance controls.

Test Principle

The wearing action is caused by two abrasive wheels which are applied at a defined pressure to the material sample which has been mounted on a rotating specimen holder. One of the most outstanding features of this testing method is the X-shaped abrasion pattern.
 
Abrasion resistance can be established by the following testing methods:
 
Weight loss method:
The sample material is subjected to a specific number of test cycles. The abraded proportion of the specimen
is established by differential weighing.
 
Visual end point method:
The sample is subjected to abrasion until the substrate becomes visible. The number of test cycles is equivalent
to the rate of wear.
 
Depth of wear method:
After a prescribed number of test cycles the depth of wear is measured using a micrometer.
 
Description
The TABER® ABRASER is a robust instrument suitable for table-top use. The accurate control and driving elements
are contained in a sturdy aluminium housing with durable baked wrinkle enamel finish. The operating data, such
as the number of test cycles and the vacuuming rate, are entered by way of a control panel with membrane keyboard.

A digital display shows readings of either the current abrasion cycle rate (wear index) or the remaining number of abrasion cycles.By using the Duo ABRASER 352 H (Type 5155), two abrasion tests with different specified parameters can be conducted simultaneously, yet independent of each other.
