Test Methods to Evaluate Thermal Properties and Performance of Insulative Coatings
|Publication Date:||27 January 2020|
This standard includes new test methods and test methods from existing standards to evaluate an insulative coating's thermal performance and integrity after thermal aging.
Thermal insulative coatings (TICs) are typically in liquid form and are applied at ambient or hot (in-service) temperatures by spray application. They are typically applied as a coating system with an anticorrosive primer. This standard does not include the performance testing of a corrosion protective primer by itself. In some of the tests in this standard, both a primer and the insulative coating are tested as a coating system. For the remaining tests in this standard, only the insulative coating is evaluated; the primer is not included. Other test methods (outside of this standard) may be used to evaluate the primers separately for their effectiveness for corrosion protection. The insulative coating manufacturer shall be contacted to determine which primer is recommended for their insulative coatings.
This standard does not apply to conventional insulation materials that are typically thicker than insulative coatings and are applied as blocks or forms to equipment or piping.
Test methods in this standard are intended to be performed in the laboratory.
The user is cautioned that other testing may be required for particular services, such as by regulatory agencies. The user is responsible for investigating the need for other testing.
This standard specifies only those tests thought to be most relevant to insulative coatings that will be heated during service.
No acceptance criteria are given for any of the specified tests in this standard. It is the responsibility of facility owners, engineering firms, and coating manufacturers to determine what acceptance criteria best meets their needs.
