Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Although an ASTM method has yet to be established, many companies are finding cycles to failure to be a sufficient means to evaluate the performance of the coating when testing with the Linear Abraser. At the conclusion of the test, wear resistance can be expressed in terms of:.

Sources that are often overlooked include: If a significant negative change in slope is asttm prior to cycles, the point at which the slope changes determines the refacing frequency.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Work Item s - proposed revisions of this standard. To determine if more frequent refacing atsm required, plot the total weight loss every 50 cycles. Inspection Validating the specifications, value and safety of your raw materials, products and assets. Not only do coatings make your product look good, they offer protection against surface damage such as corrosion, abrasion and scratch.

Unfortunately, changes are often made without the proper consideration of how they will impact product performance. The test specimen is mounted to the Taber Abraser turntable and rotated at a fixed speed under a weighted CS or CS abrading wheel. Ratings produced by this test method have correlated well with ratings produced by the falling abrasive values in Test Methods D Send us a request Need help or have a question?

These efforts might involve changing material suppliers or specifying a different type of finish. Common types include paints; varnishes; stains; and industrial coatings.

The test specimen is then placed on the abrasion tester. Before each test and after every cycles, the abrading wheels are resurfaced with an S refacing disc to standardize the wheel surfaces. But the test is not as simple as it may appear. Resistance to abrasion is atsm as the ability of a material to withstand mechanical action such as rubbing, scraping, or erosion. The haze or original weight of test specimen is measured. Historical Version s - view previous versions of standard.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

A vacuum system removes any loose debris generated during testing.

Taber Abrasion ASTM D1044 (Haze), ASTM D4060 (Weight Loss)

Certification Formally confirming that your products and services meet all trusted external and internal standards. Wear Index, the weight loss per specified number of revolutions usually under a specified load or g ; Wear cycles per aztm, the number of cycles required to wear through a 1-mil thickness of coating; or, Cycles to failure, the number of test cycles to wear away the coating or to expose the substrate But the test is not as simple as it may appear.

TABER Industries: Abrasion Resistance of Organic Coatings

Taber abrasion is a test to determine a plastic's resistance to abrasion. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

A haze measurement or final weight is taken. Although an ASTM method has yet to be established, many companies are finding cycles to failure to be a sufficient means to evaluate the performance of the coating when testing with the Linear Abraser. Depending on abrading type and test specimen, the wheel surface may change that is, become clogged due to the adhesion of debris generated during the test and must be refaced at more frequent intervals as agreed upon by the interested parties.

  1. In it something is. I thank for the help in this question, now I will know.

    I apologise, but, in my opinion, you commit an error. Let's discuss it.
