Agriculture and Markets, 10B Airline Drive, Albany, NY 12235, or in the office
of the Department of State, One Commerce Plaza, 99 Washington Avenue, Suite
650, Albany, New York 12231.
(b)
Scales used in the sale of delicatessen products may continue to compute,
display and record prices in terms of fractions of a pound.
(c) The municipal authority with jurisdiction
over taximeters may elect to permit hand written receipts for fares.
(d) Scales used by stockyard owners, market
agencies, dealers, packers and live poultry dealers or handlers to weigh
livestock or live poultry for the purpose of purchase, sale, acquisition or
settlement shall be equipped with a printing device which shall be capable of
being used for recording weight values on a scale ticket or other document used
for this purpose.
(e) Gasoline
dispensing and measuring device vapor recovery systems shall meet and be
subject to the following requirements and test procedures:
(1) Such systems shall have a primary nozzle
shut-off, automatic in operation, to stop liquid flow when the liquid level
reaches the delivery nozzle.
(2)
Such systems shall have an effective means to prevent the recirculation of
liquid through the vapor return line, including but not limited to a secondary
shut-off device.
(3) Such systems
shall include a recirculation prevention device which shall shut off the flow
of liquid prior to permitting the passage of liquid through the vapor return
line in excess of 0.3 gallon.
(4)
Assist systems shall operate at the vacuum level recommended by the
manufacturer but not at more than 10 inches HO vacuum as measured at the nozzle
during delivery.
(5) Such systems
shall operate without the failure of any component between an ambient
temperature of 0°F and 105°F.
(6) The following type approval test procedures and tolerances
shall apply to all such vapor recovery systems:
(i) The test to determine the acceptability of an individual
nozzle shall be conducted utilizing a closed test unit.
(ii) The test procedure for primary shut-off
shall positively demonstrate proper initial automatic shut-off and a failure to
override such shut-off in 10 consecutive attempts made as rapidly as the nozzle
permits. For nozzles that will allow a tight seal with the vehicle fill
opening, the 10 attempts to override shall not increase the amount indicated by
the dispensing and measuring device by more than 0.1 gallon. This test shall be
performed on at least six representative nozzles and shall be repeated at least
10 times on each such nozzle.
(iii) The test procedure for secondary
shut-off (if so provided) shall positively demonstrate nozzle shut-off when an
attempt is made to dispense liquid into a closed test unit. Prior to an attempt
to dispense liquid, the vapor return line shall be filled with sufficient
liquid to activate the secondary shut-off device. The end of the nozzle must be
inserted into the opening of an empty test unit with care so that the liquid
does not drain back into storage. This test must be performed on at least six
nozzles and shall be repeated at least 10 times on each such nozzle.
(iv) Prior to a delivery accuracy test, the
dispensing and measuring device must be adjusted as close as practicable to
zero and within the acceptance tolerance for the device.
(v) Compliance with delivery tolerance
requirements shall be based on observations of refueling of at least 300
vehicles under conditions representative of the anticipated range of actual
field use.
(vi) Test procedures to
determine compliance with delivery tolerance requirements shall include the
observation of refueling operations with a liquid trap in the vapor return hose
so that all liquid entering the hose can be collected and measured. Trap
placement and tester actions shall be such as to produce the least possible
change from normal operations. The trap shall be installed at the outlet end of
the vapor hose and outside of the dispenser. The vapor return hose shall be
drained into the trap after each refueling. The delivery tolerance tests shall
be performed on various sizes of passenger vehicles, vans and trucks and shall
utilize varied fuel delivery rates, hold-open clip and self-serve modes,
complete and partial fills, fuel types and nozzle orientations. A system shall
be rejected if there is a failure during any one individual delivery to meet
the 0.2 percent tolerance set forth at subparagraph (viii) of this
paragraph.
(vii) The test
procedure to determine compliance with the limits of vacuum on an assist system
shall include an appropriate gauge, pressure transducer or indicator installed
at the nozzle. When the system is operated it must function within the limits
specified by this subdivision.
(viii) In a vapor recovery systems test the quantity of measured
product entering the vapor return line during a delivery shall not exceed 0.2
percent of the total fuel delivered during any one individual delivery and 0.02
percent of the total fuel delivered to the 300 or more vehicles fueled during
the test period.
(ix) The
commissioner may accept the test results from any other jurisdiction with at
least five year's experience testing such systems so long as the procedures and
tolerances used are at least as strict as those set forth in this
subdivision.
(7) The
following field compliance test procedures and tolerances shall apply to all
such vapor recovery systems:
(i) The nozzle
shall be inserted into the fill opening of the vehicle tank or test unit in
accordance with the instructions on the device, if any, and common public
usage.
(ii) A primary shut-off
shall occur when the nozzle is contacted by the liquid with the dispenser
operating at any discharge rate but not less than the minimum rate allowed by
the hold-open clip, if any, or three gallons per minute, whichever is
less.
(iii) After an original
liquid activated (primary) shut-off and with the nozzle outlet immersed in
liquid, six additional attempts to activate the nozzle shall be made as rapidly
as the installation permits. For nozzles that will allow a tight seal with the
vehicle fill opening, the six additional attempts to override the nozzle shall
not increase the amount indicated by the dispenser by more than a total of 0.1
gallon. The 0.1 gallon limit does not apply to vehicle tests.
(iv) If the system is equipped with a
secondary pressure activated shut-off, 0.1 gallon of fuel shall be poured into
the vapor hose while as much of the hose as permitted by the installation shall
be placed lower than the nozzle. The nozzle shall be placed rapidly into the
empty test unit or a vehicle tank that is within three gallons of being full
including the fill inlet. Automatic shut-off must occur when the nozzle is
activated.
