Full Description

1.1 Aboveground Survey Techniques

1.1.1 This standard presents acknowledged procedures for the application of aboveground techniques to
evaluate the coating condition of underground metallic pipelines.

1.1.2 This standard does not designate practices for specific situations; the complexity of some underground
pipeline and environmental conditions preclude standardizing the application of some of the coating evaluation
techniques. Deviation from this standard may be warranted in specific situations, provided those responsible
can demonstrate that the objectives expressed in this standard have been achieved.
1.1.3 This standard does not include procedures for close-interval pipe-to-soil potential surveys (CIS). CIS
procedures are covered in NACE SP0207.3

1.1.4 Alternating current (AC) attenuation surveys are used to provide an assessment of the overall quality of
the pipe coating section by section; however, this technique is not typically effective in identifying individual
holidays.

1.1.5 Direct current (DC) and AC-voltage gradient surveys are used to evaluate in detail the coating condition
on buried pipelines and identify and classify coating holidays.

1.1.6 The Pearson survey, named after J.M. Pearson (the individual who developed the technique), is used to
locate coating holidays.

1.1.7 The pipeline operator must determine which survey techniques are suitable for providing required coating
condition assessment information for each pipeline or pipeline section.
