Historical Standard: Standard Test Method for Disbonding Characteristics of Pipeline Coatings by Direct Soil Burial

ASTM G19

Scope

1.1 This test method describes the determination of the relative disbonding characteristics of damaged coatings on steel pipe by cathodic protection potentials in direct soil burial. This test method is intended to apply to the testing of all types of nonmetallic pipeline coatings and tapes including thermoplastics, thermoset, and bituminous materials.

1.2 Results may vary widely when test sites are in different geographical areas of the country, and even in different localities.

1.3 This test method is limited to nonconducting, or nonmetallic pipe coatings and is not applicable to conducting materials such as zinc coatings on steel pipe.

1.4 This test method may involve hazardous operations and equipment. This test method does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this test method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.5 The values stated in SI units to three significant decimals are to be regarded as the standard.
