Description / Abstract:
This standard practice covers testing criteria for evaluation of
protective coating systems for use on iron and steel surfaces. It
is not recommended for the evaluation of hot-dip galvanizing or
metalizing.
The protective coating systems are intended for use on bridges,
similar structural steel, and other ferrous metal surfaces, both
new and existing, prepared by abrasive blast cleaning, which are
subject to corrosive atmospheric environments, such as marine,
industrial, deicing chemicals, and high humidity.
The values stated in SI units are to be regarded as the
standard.
This standard practice may involve hazardous materials,
operations, and equipment. It does not purport to address all
safety problems associated with its use. It is the responsibility
of the user of this standard practice to establish the appropriate
safety and health practices and determine the applicability of
regulatory limitations prior to use.
Note 1—The testing format for this standard
practice has been developed around a three-coat system consisting
of a zinc primer, epoxy or urethane intermediate, and an aliphatic
urethane finish coat.
