Standard Guide for
Assessing the Condition of Aged Coatings on Steel
Surfaces1

This standard is issued under the fixed designation D 5065; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of the last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This guide describes general procedures for conducting
a detailed assessment of the condition of aged coatings on steel
structures and the extent of rust breakthrough of the coated
surface. Additional assessment may be required to support
coating failure analyses or other job-specific needs.

1.2 This guide does not address the problem of determining
the structural condition of a steel substrate. It provides procedures to determine the percent of the surface rust, but not the
severity, condition, or cause of such rusting.
NOTE 1—A more comprehensive condition assessment procedure, Practice F 1133, is based upon two sets of visual standards, one for level and one
for the extent of deterioration, has been developed for determining the
condition of coatings on ship hulls.

1.3 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
