Understanding Adhesion Test Data - The Importanceof Round Robin Evaluations

Understanding Adhesion Test Data - The Importanceof Round Robin Evaluations
Available for download

Current ASTM standards require a statement of precision and bias as part of the standard test method. This statement allows a user to properly interpret results obtained by a competent operator. Development of these statements typically involves an interlaboratory study, commonly referred to as a round-robin test.

Current ASTM standards require a statement of precision and bias as part of the standard test method. This statement allows a user to properly interpret results obtained by a competent operator. Development of these statements typically involves an interlaboratory study, commonly referred to as a round-robin test.  The paper presents the results of an interlaboratory study (ILS) on ASTM D4541, Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers. A key finding of the study is that results vary depending on the test instrument used. In order to properly report on and interpret the test data, one needs to identify the instrument used. When the instrument is known, ASTM data on precision and bias allows a user to properly interpret the test data. The paper also discusses the process used by ASTM for conducting an ILS, and the round-robin tests currently under development by ASTM D01.46 – Industrial Protective Coatings.

Pull-Off Adhesion Testing of Coatings - Improve Your Technique

Pull-off adhesion testing is widely used to assess the protective coating process. It is also used to determine if a coating is fit for service in new construction and for repairs to existing structures. The result is often critical to the acceptance or rejection of a coating process, as the adhesion value quoted by the paint manufacturer can be adversely affected by aspects of the coating process. Low adhesion values are indicative of premature failure of the coating and are often due to inadequate surface preparation of the substrate.

Powder Coating - Contract Metal Finishing; How to Avoid Premature Coating Failures

Product Number: 41208-406-SG

Every year millions of dollars are spent litigating the responsibility issues associated with the repair or replacement of coated products that have prematurely lost their decorative or protective value due to improper coating specification or application. Many of these failures could have been avoided if the proper finishing materials and methods were specified, followed, certified and documented.

Proposed Standard for Levels of Inspection

Product Number: 41208-431-SG
Author: Louis G. Lyras, Dave Hatherill, William LePage
Publication Date: 2008
$20.00

This paper identifies the problems with current inspection procedures and discusses a proposed standard for levels of inspection that the owner will specify in the contract documents. The paper identifies the problems and cost to contractors and owners for inspection without clear and specified inspection standards and will demonstrate a savings without compromising the quality of the work.
