3.22.4.4
General Operating Tests
General operating tests shall be conducted during or after air flow and
vacuum tests to ensure that the turbines start up and cycle properly. In
addition, each operatory tube shall be tested with at least 1 liter 1 quart
of water to assure proper separation after the water is pulled into the
evacuation system.
3.22.5
Phenolic Resin Coatings
A certificate of compliance shall be submitted by the coating manufacturer
that documents successful use of coating system under service conditions
indicated on the drawings for a minimum of 2 years at three different
locations and that certifies that the coating material and application
comply with the testing procedures outlined in this specification.
3.22.5.1
Test Panels
Test panels shall be prepared in accordance with ASTM D 609. If steel test
panels are utilized, the steel substrate shall be 0.607 mm 24 gauge in
thickness. The panels shall be coated with one coat wash primer, then
pigmented baking phenolic to a dry film thickness of 0.1016 to 0.1524 mm
0.004 to 0.006 inch, then clear baking phenolic to a total dry film
thickness of 0.1270 to 0.1778 mm 0.005 to 0.007 inch. The panels shall
then be subjected to the tests specified in the following paragraphs.
3.22.5.2
Heat Test
A coated test panel shall show no cracking, flaking, or other failure after
the panel has been tested in accordance with ASTM D 2485, with a furnace
temperature of 204 degrees C 400 degrees F.
3.22.5.3
Abrasion Test
A coated test panel shall show no more than a 40 milligram loss when tested
in accordance with ASTM D 4060, utilizing a Tabor Abraser CS-17F wheel with
a 1000 g. weight for 1000 cycles.
3.22.5.4
Corrosion Test
A coated test panel shall show no corrosion after being subjected to a 500
hour salt spray test in accordance with ASTM B 117.
3.22.6
Defective Work
If inspection or test shows defects, such defective work or material shall
be replaced or repaired as necessary and inspection and tests shall be
repeated. Repairs to piping shall be made with new material. Caulking of
screwed joints or holes will not be acceptable.
3.22.7
System Flushing
3.22.7.1
During Flushing
Before operational tests or disinfection, potable water piping shall be
flushed. Sufficient water shall be used to produce water velocity that is
capable of entraining and removing debris in all portions of the piping
system. This requires simultaneous operation of all fixtures on a common
branch or main in order to produce a flushing velocity of approximately 1.2
