a.
(saybolt test), and dirt (gravimetric).
b.
On softened water for hardness (soap test or colorimetric test),
and boiler blowdown water for pH (colorimetric) and conductivity
(potentiometer).
c.
For water (distillation) and sediment (gravimetric) in fuel oil.
2.19
WELDING MATERIALS
Welding materials shall comply with Section 2, ASME BPVC SEC II-C. Welding
equipment, electrodes, welding wire, and fluxes shall be capable of
producing satisfactory welds when used by a qualified welder or welding
operator using qualified welding procedures.
2.20
MOTORS AND DRIVES
shall be designed for continuous operation at rated load under usual
service conditions as defined by NEMA. Unless specifically noted
otherwise, motors less than 3/8 kW 1/2 hp shall be 115 volt, 60 Hz, single
phase, capacitor-start, or permanent split capacitor, with Class B
insulation for 40 degrees C 104 degrees F ambient. Unless specifically
noted otherwise, motors 3/8 kW 1/2 hp and larger shall be 460 volt, 60 Hz,
three phase, Design B, squirrel cage induction with a minimum insulation of
Class F for 40 degrees C 104 degrees F ambient. Size motors to meet power
requirements of the driven unit at design conditions, including drive and
coupling losses which are incurred, without loading the motor beyond its
nameplate horsepower rating. Minimum service factor for open drip-proof
motors shall be 1.15 and for totally enclosed, fan cooled motors 1.0.
Motor shall be quiet operating. Bearings shall be heavy duty, grease
lubricated, anti-friction, single shielded, regreasable type and shall have
approved lubricating fittings extended to an easily accessible location for
field servicing. Provide sole plates for motors installed on concrete
pads. Motors shall have copper windings.
2.21
SOURCE QUALITY CONTROL
2.21.1
Factory test air compressor package at full load for not less than 2 hours.
Check capacity, smoothness of operation, alternation of units, and proper
operation of the air unloaders during the test.
2.21.2
Variable Speed Motor Controller Factory Test
Burn-in tests shall be conducted for at least 50 hours at rated conditions.
Replace each component that fails during the burn-in test, and the test
shall be run on the entire assembly for the complete 50 hours. Burn-in
test shall not be complete until the entire assembly has operated for 50
hours without failure.
