Abrasion Tester: A Comprehensive Guide for Material Testing
Table of Contents
Abrasion testers provide valuable information concerning the wear resistance of various materials such as textiles, metals, plastics, rubbers, coatings, and ceramics. They are widely used in industries such as automotive, aerospace, construction, packaging, and consumer goods. This article will provide a comprehensive guide to help you choose the best abrasion tester based on your requirements.
What Is Abrasion Tester?
Abrasion Tester is a device that is used extensively in material testing to determine the wear and tear properties of a material. It plays a pivotal role in ensuring the quality and durability of materials in various industries.
There are different types of abrasion testers, and the selection of the suitable type largely depends on various factors such as the type of material, the intended application, standard specifications, and test objectives.
Types of Abrasion Tester
According to different materials, the ASTM standards related to abrasion resistance testing are:
For Textile Fabrics
-ASTM D4966, also known as the Martindale abrasion test
-ASTM D3884, also known as the Taber abrasion test
For Wet Suit Materials
For Organic Coatings
For High-Strength Composite Materials
For Metallic Thermal Spray Coating
How Does Abrasion Tester Work?
Martindale abrasion tester is a typical machine used to measure the abrasion resistance of fabrics or textiles. It operates by rubbing a circular, weighted test fabric against an abrasive surface under specified conditions.
The test fabric is attached to a holder and placed on the abrasion table, which rotates in a circular motion. The abrasion table consists of four or more stationary discs with abrasive material, such as emery paper, mounted on them. The test fabric is continuously rubbed against the abrasive discs in a circular motion. Additionally, a weight is frequently added on the holder to exert the required load for the test.
As the test proceeds, the abrasion damage to the fabric is visually evaluated at specific intervals, often after a designated number of cycles. The evaluation can be done by observing the fabric’s physical appearance or by measuring the mass loss of the fabric.
