ASTM G 8 : Standard Test Method for Cathodic Disbonding of Pipeline
Coatings
These test methods cover accelerated procedures for simultaneously
determining comparative characteristics of insulating coating systems
applied to steel pipe exterior for the purpose of preventing or
mitigating corrosion that may occur in undergroung service where the
pipe will be in contact with inland soils and may or may not receive
cathodic protection. They are intended for use with samples of coated
pipe taken from commercial production and are applicable to such samples
when the coating is characterized by function as an electrical barrier.
This test method is intended for testing coatings submerged or immersed
in the test solution at room temperature. When it is impractical to
submerge or immerse the test specimen, Test Method G 95 may be
considered where the test cell cemented to the surface of the coated
pipe specimen. If higher temperatures are required, see Test Method G
42. If a specific test method is required with no options, see Test
Method G 80.
The values stated in SI units to 3 significant decimals are to be
regarded as the standard. The values given in parentheses are for
information only.
