This standard describes six coating systems designed to protect the exterior
surfaces of steel pipelines and the associated fittings used by the water supply
industry in aboveground locations. The coating systems described may not perform
or cost the same, but they are presented so that the appropriate coating system can be
selected for the site-speciflc project requirements.
1.1.1 Maximum temperatures. The maximum service temperature of the
coating systems listed in this standard is based on the maximum service temperature
of potable water. Consult the coating manufacturer for conditions and limitations.
