This guide is intended to aid the coating specification writer in selecting and specifying the appropriate inspection criteria. It indicates the inspection requirements that may be employed for each of four service environments including mild, moderate, severe, and immersion.

Formerly under the jurisdiction of Committee D33 on Protective Coating and Lining Work for Power Generation Facilities, this guide was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

1.1 This guide is intended to aid the coating specification writer in selecting and specifying the appropriate inspection requirements. It indicates the inspection requirements that may be employed for each of four service environments including mild, moderate, severe, and immersion (see Table 1).

1.2 In order to aid the user in determining when to specify inspection requirements, a relationship between the consequence of failure and the suggested level of inspection is demonstrated (see Fig. 1).

1.3 It is not the intent of this guide to address the selection of protective coating systems, to specify surface preparation and application requirements, or to be a referenced document in a specification.
