(b)
Whenever a grade, brand, blend,
			 or mixture is offered for sale from a device at more than one unit price, then
			 all of the unit prices at which that product is offered for sale shall be
			 displayed or shall be capable of being displayed on the dispenser using
			 controls available to the customer prior to the delivery of the product. It is
			 not necessary that all of the unit prices for all grades, brands, blends, or
			 mixtures be simultaneously displayed prior to the delivery of the product. This
			 subsection shall not apply to fleet sales, other contract sales, or truck
			 refueling sales (e.g., sales from dispensers used to refuel trucks).
[Effective and nonretroactive as of January 1,
				1991]
(Amended 1989 and 1997)
S. 1.6.4.2. Product Identity.
(a) A device shall be able to conspicuously
			 display on each side the identity of the product being dispensed.
(b) A device designed to dispense more than
			 one grade, brand, blend, or mixture of product also shall be able to display on
			 each side the identity of the grade, brand, blend, or mixture being
			 dispensed.
S. 1.6.5. Money-Value Computations.
(a)
A computing device shall compute
			 the total sales price at any single-purchase unit price (i.e., excluding fleet
			 sales, other price contract sales, and truck stop dispensers used only to
			 refuel trucks) for which the product being measured is offered for sale at any
			 delivery possible within either the measurement range of the device or the
			 range of the computing elements, whichever is less.
(b) The analog sales price indicated for any
			 delivered quantity shall not differ from a mathematically computed price
			 (quantity x unit price = total sales price) by an amount greater than the value
			 in Table 1. (Amended 1984, 1989, and 1993)

S&T Committee 2004 Interim Report
POS nominal capacity or the Universal. Product Code is
				illegible, but the weight and unit price information are available on the item
				label and can be entered in the POS to calculate a price.
Handbook 44 includes provisions, to deter fraudulent use of the
				manual weight entry feature. Paragraph S.1.12. describes when a scale can
				accept such as entry and how it must be identified. Paragraph UR.3.9. specifies
				only four applications where the use of manual weight entries are permitted.
				Handbook 44 also requires that a scale shall be suitable for use. which
				includes its weighing capacity. The feature is not intended as a substitute for
				a system with insufficient weighing capacity
The Committee acknowledges that manual weight entries occur
				writh gross and net
				wreight packages. The Committee considered several
				proposals to address this practice. These proposals were either himted in the
				applications they covered, unclear on what tare information that must be
				recorded, or appeared to prohibit manual tare entries. After lengthy discussion
				at the 2003 NCWM Annual Meeting, the Committee agreed to keep the following
				proposal an information item to allow sufficient time for these deficiencies to
				be addressed:
S.1.12.
Manual Weight Entries. - A de\ice shall accept
				an entry of a manual weight value only when the scale is at gross load zero and
				the scale
gross or net* weight
indication is qt_ zero
				. Recorded manual weight entiies, except those on labels generated for packages
				of standard weights, shall identify' the weight value as a manual weight entry
				by one of the following terms: "Manual Weight, " "Manual Wt," or "M,iN WT. "
				The use of a symbol to identify' multiple manual weight entries on a single
				document is pennitted, provided that the symbol is defined on the same page on
				which the manual weight entries appear and the definition of the symbol is
				automatically printed by the recording element as part of the document.

UR.3.9. Use of Manual ss Weight Entries. - Manual weight
				entries are permitted for use in the following applications only:
				(1
1 on a point-of-sale system interfaced with scales
when credit is given for a wreighed item m --ss
				s
, or when an item is pre-weighed and marked with the correct net
				weight
: (21 when a device or system is generatemj labels for
				standard weight packages; (3) when postal scales or weight classifiers
are
generateing manifests for packages to be picked up
				at a later tune; -ef
and
(41 when- on hvestock
scale
and vehicle scale systems generate weight
				tickets to correct erroneous tickets.
The Central Weights and Measures Association did not take a
				position on this issue until it had a chance to review positions taken by the
				NTETC Weighing Sector when tbe Sector meets later in 2003.
During its September 2003 Annual Conference, the WWMA examined
				the recommendation developed by the 2003 S&T Committee and an alternate
				proposal that limited use of the manual weight entry feature to point-of-sale
				(POS) systems. The WWMA agreed that limiting the feature to POS systems was too
				restrictive. The WWMA. also agreed that the S&T Committee's recommendation
				would make the current practice of entering preset tare values with a load on
				the scale during direct sale transactions very difficult. Consequently, the
				WWMA recommended the alternate proposal for paragraph S.1.12.
				show:n in the recommendation above and modified
				paragraph U.3.9. to limit manual weight entries to either gross or net weighed
				items as follows:
UR.3.9. Use of Manual Weight Entries. - Manual gross
or net
weight entries are permitted for use in the
				following applications only:
(
1
1 on a
				point-of-sale system interfaced with scales
when credit is given
				for a weighed item e eeee
, or when an item is pre-weighed and
				marked with the correct net weight
; (2) when a device or system is
				eee
ing
labels for standard weight packages; (3) when
				postal scales or weight classifiers
are
genera
ting
manifests for packages to be picked up at a
				later time: and (41 on livestock scale and vehicle scale systems
that
generate weight tickets to correct erroneous
				tickets.
The Northeastern Weights and Measures Association opposed the
				carryover recommendation developed by the 2003 S&T Committee because it
				found the language too cumbersome to address all possible scenarios where a
				manual w:eight entry is used.
The Scale Manufacturers Association (SMA1 supported tbe WWMA
				proposal to modify' paragraph S.1.12. and recommended an alternate proposal to
				modify paragraph UR.3.9. show:n in the
				recommendation above. The SMA
S&T Committee 2004 Interim Report
Modify paragraph S.6.4 as follows: S 6.4. Railway Track
				Scales.
(a) A railway track scale
			 shall be marked wirh the maximum capacity of each section of the load-receivmg
			 element of the scale. Such marking shall be accurately and conspicuously
			 presented on, or adjacent to the identification or nomenclature plate that is
			 attached to the indicating element of the scale.
fbli
The nominal capacity of a
raHii'av track
scale shall not exceed
the lesser of 640 000 lb or SO 000 lb for each 5 feet of
				wreigh rail length or portion thereof and; the
				section capacity (SC) multiplied by the number of sections (N) of the scale
				minus O.J. The formula is stated as Nominal Capacity = SC x fN -
				0.51.
[Nonretroactive, as ofJannaiy 1,
				2002]
Add new paragraph UR.X. as follows:
UR.X.
Railcars weighed statically shall be
				uncoupled and alone on the load-receivmg element as the weight is
				recorded.
The Committee has not heard sufficient technical grounds for
				modifying the formula to permit unlimited nominal capacities for railway track
				scales. The proposal appears to have little support fiom parties that
				w:ould be most affected by the changes to paragraph
				S.6.4., if the proposal were adopted. Additionally. there remains some concern
				about the difficulty of locating sufficient test weights and the ability to
				concentrate a test load on scales with capacities that exceed 640 000 lb.
				Consequently, the Committee withdraws the proposal from the agenda and asks the
				AAR and Systems Associates, Inc. to find an alternate proposal that is amenable
				to both parties arid the industries they represent.
The Committee acknowledged that the NEWMA proposal to modify
				Table 4, Minimum Test Weights and Test Loads begins to address the maximum test
				load on all large capacity scales. However, the proposal erroneously appeared
				in Interim Agenda Item 320-2 when it is a separate issue that has merit, but is
				insufficiently developed for Committee action. Consequently, NEWMA's proposal
				now appears in Appendix A as developing item Part 2, Scales Code in the 2004
				Interim Report.

				2002
, and 2004)
(Footnote 1 Added 2001)
Add new Note 24. to Table S.6.3
h.
Notes for
				Table S6..i.a as follows:
24, The section capacity shall be prefaced by the
				words "Section Capacity" or
an
abbreviation of that term.
				Abbreviations shall be "Sec Cap" or Sec C." All capital letters and periods may
				be used, (Added 2004)
Discussion: The CWMA believes that current Handbook 44 may be
				mterpreted to prohibit the abbreviation of section capacity. Because some
				device identification badges are limited in space, manufacturers abbreviate
				marking information. The CWMA recommends adding a new paragraph S.6.4.3. that
				requires identification of section capacity information with a prefix and
				defines acceptable abbreviations foi that prefix. The CWMA did not submit
				specific language for addressing the abbreviation of section capacity in Table
				S 6 3.a Marking Requirements and Table S.6.3.b. Notes For Table S.6.3.a.
The Western Weights and Measures Association (WWMA) heard that
				the NTETC Weighing Sector and manufacturers support the intent of the proposal.
				FTmvever, the WWMA believes the CWMA proposal should be simplified and modified
				for clarity. The WWMA agreed that use of the abbreviations "SC" and "S Cap" to
				identify section capacity are not acceptable because they might be interpreted
				to represent scale capacity. The WWMA considered a recommendation to include
				identification requirements for section capacity in General Code paragraph
				G-S.l. Identification since that requirement specifies other marking
				information and prefixes. Ultimately, the WWMA decided to address the
				abbreviation of ''section capacity" as a Scale Code requirement. The WWMA
				worked with the NTETC Weighing Sector Technical Advisor to develop the
				alternate proposal to modify Table S.6.3.a. and Table S.6.3.b. as shown in the
				recommendation above
The Scale Manufacturers Association supported the proposal for
				including m Table S.6.3.a. and Table S.6.3 b. language that that requires a
				prefix to identify the scale's section capacity and specifies how the prefix
				must be abbreviated.
S&T Committee 2004 Interim Report
The Committee agreed that the best approach for designating a
				prefix that identifies the scale's section capacity is the WWMA alternate
				proposal. The WWMA proposal is consistent with the current practice of listing
				other scale marking requirements in one table. The Committee modified the WWMA
				proposal for new Note 24. by removing the word '"Acceptable." The Committee
				does not believe it is necessary to qualify that the abbreviation is acceptable
				since this text does not appear in other marking requirements and it is
				understood what abbreviation is acceptable because they are adequately defined
				in the note's text. Consequently, the Committee recommends modifying Table
				S.6.3 a. to include a marking requirement for a prefix that identifies the
				scale's section capacity and a corresponding note be added to Table
				S.6.3.0.
320-4 V N.3.2.
			 Field Standard
Weight
Carts
Source: Carryover Item 320-11. (This item originated from the
				Northeastern Weights and Measures Association (NEWMA) and first appeared on the
				Committee's 2003 agenda.)
Recommendation: Add new paragraph N.3.2.
N.3.2.
Field Standard Weight Carts. - Field
				Standard Weight Carts that comply with the tolerances expressed in Fundamental
				Considerations, garagranh 3.2. (i.e.. one-third of the smallest tolerance
				nnrihed) may be included as nni t of the minimum 1 enuii ed test load for shift
				tests and other test procedures. (Added :>004)
Discussion: The original NEWMA proposal was intended to modify
				the NTST Handbook 44 Scales Code to recognize die use of weight carts during a
				shift test. During its October 2003 Interim Meeting, NEWMA indicated that its
				original proposal was not ready for adoption by the NCWM. New York noted that
				NEWMA's proposal shown below should include a reference to the Handbook 44
				Fundamental Considerations 3.2 Tolerances for Standards. New York also
				recommended modifying NEWMA's proposal to eliminate any requirements that
				specify a particular type of information diat must be included in the weight
				cart's calibration report as follows:
N. 1.3.4.1. Weight Carts. - Weight carts may be included as
				part of the minimum required test load required in
N.l.3.4. provided that the mass value of the weight cart has
				been determined by weights and measures and is clearly marked thereon. Further,
				a certificate of calibration issued by the weights and measures jurisdiction
				that issued the weight certificate must be available at all times. e e eeeee ee
				eeee e.
At die 2004 NCWM Interim Meeting, the Committee heard that the
				NEWMA proposal was unclear as to how the mass value is determined by a weights
				and measures jurisdiction. The Committee agreed that the portions of the
				proposed language intended to address the reference standard should include
				information about the uncertainty of the scale used as die reference standard
				rather than the scale's minimum graduation size. The uncertainty of the
				reference scale is essential in the calibration report for the weight cart to
				establish the accuracy of measurements made with the field standard.
The Central Weights and Measures Association (CWMA) developed
				an alternate proposal that specified weight carts may be used as part of the
				minimum load for shift rests on vehicle scales. The CWMA believes that an
				additional proposal is needed to permit the use of weight carts in tests other
				than shift tests. The CWMA also recommended that die proposal make reference to
				weight carts meeting the Fundamental Considerations Tolerance for Standards
				when a weight cart is used as the testmg apparatus in accordance with the
				requirements for calibration of a field test standard in NIST Handbook 105-8,
				Specification and Tolerances for Field Standard Weight Carts.
The Committee agreed that the test note should include language
				that permits use of weight carts for shift tests and other test as well as
				specify a standard for the weight cart. The Fundamental Considerations
				prescribes the error in a field test standard used by weights and measures
				officials. The Committee also noted that the proposed paragraph designation is
				already in use. Consequently, the Committee modified the CWMA proposal as shown
				in the recommendation above to include a new paragraph designation and require
				diat field standard weight carts comply widi the guidelines for test apparatus
				in the Fundamental Considerations.
The Committee acknowledges that it is general knowledge that
				NIST Handbook 105-8 is available through the NIST Weights and Measures Division
				web site at
wwwjrist.gov/own
and
				was published in December 2003.
320-5 V N.1.5. Discrimination Test
Source: Central Weights and Measures Association (CWMA)
Recommendation: Modify paragraph N.1.5. as follows:
N.1.5.
Discrimination Tat. - A discrimination test
				shall be conducted on all automatic indicating scales with the weighing device
				in equilibrium st
near
zero load and-at
near
maximum test load, and under controlled
				conditions in which environmental factors are reduced to the extent
				that
ftsy
will not affect the results obtained.
For scales equipped nith the Automatic Zero-Setting Mechanhin
				(AZSM). the discrimination ten may be conducted at a ranse outside of the
				AZSMrange.
[Nonretroactive as of January I, 1986]
"(Added
				1985)
(Amended 2004)
Discussion: The CWMA agreed that it is impossible to conduct a
				discrimination test and verify the zone of uncertainty
at
zero
				if the Automatic Zero-Setting Mechanism (AZSM) is operational. The CWMA
				believes the test should be conducted
near
zero without the
				weights and measures official having to disable AZSM. The CWMA does not want
				officials having to access the inside of scales to disable and then make
				operational AZSM or any other feature.
The Scale Manufacturers Association supports this item.
The Committee heard no opposition to the proposal. The
				Committee recognizes that there are environmental arid scale design factors
				that can affect the results of a discrimination test. The Committee also
				acknowledges that it is acceptable to perform a discrimination test at zero
				load just above the zero tracking range for scales that are equipped with AZSM.
				The test is also acceptable when performed just below the scale's maximum
				capacity in the event that a scale is set up to display an indication of over
				capacity that is less than maxmium total load in excess of scale capacity
				established in paragraph S.1.7. Capcaciry Indication, Weight Ranges, and Unit
				Weights.

Discussion: Requirements for the minimum and maximum number of
				scale divisions are listed in Table 3 Parameters for Accuracy Classes; however,
				the table presently does not recognize a limitation to the minimum arid maximum
				number of scale divisions included in user requirement, paragraph UR.1.2. Grain
				Hopper Scales. To ensure both manufacturer and users are aware of this
				limitation, the CWMA recommends adding a new footnote 5 to Table 3 making the
				information about gram hopper scales available in paragraphs intended for
				device manufacturers. The CWMA believes the paragraph UK 1.2. for the minimum
				number of scale divisions for a Class III Hopper Scale used for gram weighing
				is missed.
The Scale Manufacturers Association (SMA) opposes this proposal
				because it introduces a new application into Table 3. SMA prefers that Table _i
				not include any application requirements.
The Committee believes that adding a new note to Table 3 helps
				to clarify the allowable minimum number of scale divisions for a Class III
				Hopper Scale used in gram weighing application for the manufacturer and
				official. Addmg the Text from the user requirement into Table 3 is consistent
				with current Table 3 requirements for hopper scales and further explains the
				parameters that apply for this device type.

NIST WMD also believed that changes were required to Scales
				Code paragraph S. 1.1 .(c) to clarify the intent of the past S&T Committee
				and to prevent further misinterpretation. The S&T Committee concurred with
				this position and consequently proposed changes to paragraph S. 1.1 .(c) as
				outlined above.
During the 2004 NCWM Interim Meeting, the Committee was briefed
				on some ongoing discussions about zero indications within the Weighing Sector
				for the past several years. The Weighing Sector was presented with a retail
				scale using a touch screen with a screen saver that extends the screen's life.
				The scale screen saver changes to display the indications when the scale is off
				zero. In this example, the Weighing Sector agreed there was no fraud, but the
				scale should display a zero indication prior to a subsequent weialiment.
				Because discussions are still ongoing some Weighing Sector members believe the
				proposal may be premature.
Weights and measures officials mdicate there may be
				'"not-built-for-purpose" devices which do not comply with the proposed
				interpretation. The "not-built-for-purpose'7 devices
				are interfaced with approved devices; however, they continue weighing when off
				of zero. Consequently, officials question whether the proposed changes to
				paragraph S.l.l.(c) are intended to be nonretroactive requirements.
The Committee agreed that its interpretation of paragraph
				S.l.l.(c) is consistent with the original intent. After hearing comments about
				how some systems are designed to operate, the Committee recommends that
				additional language is needed to clarify that no marking is required if
				operator mterventiori is necessary to verify a zero condition before the start
				of a transaction. The Committee made the proposal an information item to
				provide sufficient time for input from the Weighing Sector, who did not have
				the proposal available at its 2003 meeting and for suggested language to
				address operator intervention
