Current through Register Vol. 46, No. 28, July 10, 2024
(a) Except as otherwise provided in this
				Part, the specifications, tolerances and regulations for commercial weighing
				and measuring devices shall be those adopted by the 107th National Conference
				on Weights and Measures 2022 as published in the National Institute of
				Standards and Technology Handbook 44, 2023 edition. This document is available
				from the National Conference on Weights and Measures, 1135 M Street, Suite 110,
				Lincoln, NE 68508, or the Superintendent of Documents, U.S. Government Printing
				Office, Washington, DC 20402. It is available for public inspection and copying
				in the office of the Director of Weights and Measures, Department of
				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.
