NAMEPLATES
Attach laminated plastic nameplates to equipment, gages, thermometers, and
valves. Nameplates shall be Melamine plastic, 3 mm 0.125 inch thick, black
with white center core, matte finish surface and square corners.
Accurately align lettering and engrave into the white core. Minimum size

minimum of 6 mm 0.25 inch high normal block style. Key the nameplates to a
chart and schedule for each system. Frame charts and schedule under glass,
and locate where directed near each system. Furnish two copies of each
chart and schedule. Each nameplate inscription shall identify its
function. Equipment nameplates shall show the following information:
a.
Manufacturer, type, and model number;
b.
Contract number and acceptance date;
c.

FIELD QUALITY CONTROL
3.9.1
Inspections
Prior to initial operation, inspect piping system for compliance with
drawings, specifications, and manufacturer's submittals.
3.9.2
Piping Tests
**************************************************************************
NOTE: On projects that provide modifications to
existing piping systems, pneumatic pressure testing
and hydraulic pressure testing of newly installed
piping is much more difficult than the same testing
on a complete new system. Therefore, by means of
the following design techniques, provide for the
Contractor a piping modification design that
facilitates acceptance testing: piping design which
includes flanges at appropriate locations for
flanged blanks to be installed for testing;
specifications which include requirements for how
the modified piping shall be pressure tested;
specifications which specify which pipe sections
shall be pressure tested in the shop if absolutely
necessary.
**************************************************************************
Before final acceptance of the work, test each system as in service to
demonstrate compliance with contract requirements.
