Significance and Use

This practice is applicable to galvanized structures exposed to the atmosphere or to plant environments, including buildings, bridges, and industrial plant constructions.

It provides for the collection of data to document the protection afforded by the galvanized coating.

Method A for conducting a coating thickness survey aims essentially at an assessment of the general condition of the galvanized structure, at the time of the inspection, by taking thickness measurements on several members of the structure.

Method B provides for accurate monitoring of the coating thickness decrease as a function of time, at specific locations on the structure, in order to assess the corrosivity of the environment, the effect of orientation, elevation, or other factors.

Method B is not an alternate procedure to Method A, but is complementary and optional.

Scope

1.1 This practice sets forth the procedures for conducting case studies of galvanized installations. It is intended for structural members and other permanent parts of the installation, such as railings and other such fabrications.

1.2 Included in this practice are recommendations for the visual inspection of the galvanized structure, measurement of coating thickness, and reporting of results.

1.3 The values stated in SI units are to be regarded as the standard.

1.4 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.
