Abrasion Testing is where a plane, rigid surface such as a metal is scrapped to determine its resistance to wearing out. The resistance to wearing out of the material determines its quality. A firm whose objective is to produce consistent performing, durable and defect-less products oftenly conducts this test on its products.
There are many wear testing instruments that have been developed over the past 100 years. Therefore, if a firm is not in a position to tell which instrument best fits their product,it can contact research industry associations for advice. ISO and ASTM also advise firms on whether the instrument that it’s planning to use for wear testing exists.
Besides, wear is dependent on a wide range of factors. Wear includes one or more pieces of bodies and materials making its simulation neither possible nor practical. Therefore, some differences have to be accepted in wear testing processes. The process of developing a test instrument is a trial and error subject which depends on the ability of the developer.
Abrasion testing has several methods through which it’s conducted. The methods are; pin abrasion, rubber wheel abrasion, falling sand abrasion, RCA abrasion and Taber abrasion. Pin abrasion is conducted by using only two pin specimens which are the subject material and the material for reference. Rubber Wheel Abrasion is performed by placing a rectangular test sample contrary to a rotating rubber wheel and putting controlled grit size sand and flow rate between them.
Taber testing was the very first scraping method to be introduced in determining materials’ resistance. In this method a flat specimen is mounted to a platform that rotates two abrasive wheels over the specimen. It is well known for its ability to give reliable data in a very short period.
The test is conducted at the lowest price compared to any other wear testing. Taber test is conducted using a Taber Rotary Platform Abraser. Taber abraser has the ability to test wear resistance on a huge number of different materials. This is made possible by its flexibility when provided with different test loads and abrading wheels.
The Taber Industries is equipped with engineers who are experienced in the wear testing.Customers are able to reach them if they need any help concerning the wear testing process. The engineers analyse customer’s information and guide them to tackle the problems on their side.
They advise customers on techniques for evaluating and interpreting the testing results. Also, they recommend the suitable instrument for the testing. Taber Industries also allows customers to send samples of their products. Their experts then respond with tools that can help in material research and quality control. This is in case customers are faced with complicated situations in wear testing.
A lot of different materials react to changes in humidity and temperature. Therefore, Taber tests are conducted under a temperature and humidity controlled environment. This is to ensure that the wear testing results are not interfered with by environmental factors. Taber testing can be performed on materials like; safety gloves, ID and credit cards, glass, leather, non-wovens, deck coverings, paints and varnishes, digital media, floor coverings among many others. Taber abraser has the ability to test both rigid and flexible materials.
Through Taber’s testing services customers have been able to; control the levels of product failure, figure out whether products comply with the industry standards, maximise on limited available resources, carry out independent, third party evaluations, anticipate product’s performance against another same product and to conduct material search and development. Taber testing is the easiest to conduct.
abrasion Testing has ensured continued production of quality products by firms. Although it takes this approach many years before useful data is availed.
