Publication of this notice on the NCWM's behalf is undertaken as a public service; NIST does not endorse, approve, or recommend any of the proposals or other information contained in this notice or in the publications of the NCWM.
The NCWM is an organization of weights and measures officials of the states, counties, and cities of the United States, federal agencies, and representatives from the private sector. These meetings bring together government officials and representatives of business, industry, trade associations, and consumer organizations on subjects related to the field of weights and measures technology, administration, and enforcement. NIST participates to encourage cooperation between federal agencies and the states in the Start Printed Page 32536development of legal metrology requirements. NIST also promotes uniformity among the states in laws, regulations, methods, and testing equipment that comprise the regulatory control of commercial weighing and measuring devices, packaged goods, and other trade and commerce issues.
The following are brief descriptions of some of the significant agenda items that will be considered at the NCWM Annual Meeting. Comments will be taken on these and other issues during several public comment sessions. This meeting also includes work sessions in which the Committees may also accept comments, and where they will finalize recommendations for possible adoption at this meeting. The Committees may withdraw or carryover items that need additional development.
Some of the items listed below provide notice of projects under development by groups working to develop specifications, tolerances, and other requirements for devices used in the retail sales of engine fuels and the establishment of approximate gallon and liter equivalents to diesel fuel that would be used in marketing both compressed and liquefied natural gas. These notices are intended to make interested parties aware of these development projects and to make them aware that reports on the status of the project will be given at the Annual Meeting. The notices are also presented to invite the participation of manufacturers, experts, consumers, users, and others who may be interested in these efforts.
The Specifications and Tolerances Committee (S&T Committee) will consider proposed amendments to NIST Handbook 44, “Specifications, Tolerances, and other Technical Requirements for Weighing and Measuring Devices.” Those items address weighing and measuring devices used in commercial applications, that is, devices that are used to buy from or sell to the public or used for determining the quantity of products or services sold among businesses. Issues on the agenda of the NCWM Laws and Regulations Committee (L&R Committee) relate to proposals to amend NIST Handbook 130, “Uniform Laws and Regulations in the area of Legal Metrology and Engine Fuel Quality” and NIST Handbook 133, “Checking the Net Contents of Packaged Goods.”
NCWM Specifications and Tolerances Committee
The following items are proposals to amend NIST Handbook 44:
Scales (Including Weigh-in-Motion Vehicle Scales for Use in the Enforcement of Highway Load Limits)
Item 320-4 Weigh-in-Motion Vehicle Scales for Use in Highway Weight Enforcement
The S&T Committee is recommending adoption of a new tentative code to be included in NIST Handbook 44 that will include the specifications, tolerances, and other technical requirements for the vehicle scales used by highway weight enforcement agencies to determine the axle loads, tandem axle loads, and gross vehicle weights of trucks and other large highway vehicles while they are in motion. A tentative code has a trial or experimental status. It is not intended to be enforced until adopted as a permanent code by the NCWM. The proposed tentative code includes recommended tests and tolerances for vehicle scales used to weigh vehicles in motion as well as user requirements that will ensure devices are maintained and operated properly, allowing weighing results to be used to carry out highway weight enforcement programs across the nation. The intended application of these scales is to weigh vehicles, while in motion, for the purpose of screening and sorting the vehicles to determine if a static weighment is necessary.
Belt-Conveyor Scale Systems
Item 321-1 Belt-Conveyor Scale Systems
Belt-conveyor scales are used in a wide variety of applications for weighing coal, grain, ore, and many other raw materials or products. Currently, only scales that are fully integrated into a conveyor system are permitted under NIST Handbook 44. The S&T Committee is recommending for adoption new definitions and proposals to broaden the scope of the requirements to allow fully “self-contained weigh-belt systems” to be covered by the specifications, tolerances, and other technical requirements in NIST Handbook 44 so these devices may be utilized in commercial transactions.
Liquid Measuring Devices
Item 330-2 S.2.2. Categories of Device and Methods of Sealing
The S&T Committee is recommending for adoption language that would allow device manufacturers to supply required security and configuration related data in “event loggers” (i.e., digital systems that keep track of the number of times a calibration event occurs) to weights and measures officials and service personnel utilizing digital communications (e.g., cellular or Internet connections) or other electronic means (e.g., USB flash memory drive) in addition to the current requirement to provide a printed record of this information. This information is used to ascertain how many and what type of calibrations and configuration changes were made to a weighing and measuring device since the last official inspection or service. The S&T Committee originally considered a proposal which would allow the information to be provided in lieu of a printed record. However, based on comments received and an evaluation of the costs, practicality, and other aspects of the proposal including the data security and privacy concerns that may arise, the Committee agreed that the electronic form of the information is only permitted as a supplement to the printed record.
Liquefied Petroleum Gas and Anhydrous Ammonia Liquid-Measuring Devices
Item 332-2 N.3. Test Drafts—Use of Transfer Standards for Calibration and Verification
The S&T Committee has designated a “Developing” item on its agenda to allow the development of a proposal that would recognize the use of calibrated transfer standards (also called “master meters”) in the verification and calibration of Liquefied Petroleum Gas and Anhydrous Ammonia Liquid-Measuring Devices. Currently, most official tests of these devices are conducted using volumetric test measures or using gravimetric testing. The proposal outlined in this item includes requirements for a minimum test draft, and would allow the use of “master meters” in both service-related and official testing. This item is also intended to explore the possibility of expanding the use of transfer standards to other types of measuring devices, including those used to measure petroleum at terminals and retail outlets and to meters used to deliver home heating fuel and other products.
Mass Flow Meters
Item 337-1 Diesel Energy Equivalents for Compressed and Liquefied Natural Gas
Natural gas is sold in the marketplace in both compressed (CNG) and liquefied (LNG) states as alternative fuel choices to gasoline and diesel fuel. The S&T Committee has recommended revisions to NIST Handbook 44 to define volume units for CNG and LNG in terms of the energy equivalents for a liter or gallon of diesel fuel. The availability of these Start Printed Page 32537values should enable consumers to compare the cost and mileage economy of different fuels, and so enable informed purchasing decisions when considering the use, purchase, or lease of vehicles equipped to operate on different fuels.
Taximeters (and GPS Devices When Used in Transportation Services)
Items 354-1, 354-2, 354-3, 354-4, and 354-5
The S&T Committee is recommending for adoption this group of proposals (listed above), which includes proposed revisions and updates to the Taximeter Code in NIST Handbook 44 to address changes in technology related to indicating and recording elements (i.e., printers) and operational features including the indications required to be presented to passengers.
Item 354-6 U.S. National Working Group on Taximeters and Global Positioning System-Based Systems for Time and Distance Measurement
The S&T Committee will hear a progress report from a national working group that is studying the use of Global Positioning Systems and smart phone/web based applications in transportation services in order to develop proposed specifications, tolerances, and other technical requirements to ensure accuracy and transparency for passengers, drivers, and businesses for inclusion in NIST Handbook 44. This item is designated as a “Developing Item” on the Committee's agenda to allow further study and refinement of these issues.
Item 360-5 Electric Vehicle Fueling and Submetering
The S&T Committee is recommending adoption of a tentative code for use in electric vehicle charging and submetering for inclusion in NIST Handbook 44. The code was developed by a NIST U.S. National Working Group that continues to further refine the specifications, tolerances, and other technical requirements to ensure accuracy and transparency for drivers of electric vehicles and power resellers. The S&T Committee is also recommending for adoption proposed changes to the Section 5.55. “Timing Devices” in NIST Handbook 44 to address requirements for the timing mechanisms that are likely to be used in some recharging systems to determine additional charges for other services (e.g., parking).
NCWM Laws and Regulations Committee (L&R Committee)
The following items are proposals to amend NIST Handbook 130 or NIST Handbook 133:
NIST Handbook 130—Section on Uniform Regulation for the Method of Sale of Commodities
Item 232-3 Animal Bedding
The L&R Committee is recommending the adoption of a uniform method of sale for animal bedding that will enhance the ability of consumers to make value comparisons and will ensure fair competition. Animal Bedding is generally defined as any material, except for baled straw, that is kept, offered or exposed for sale or sold to retail consumers for primary use as a medium for any pet or companion or livestock animal to nest or eliminate waste. If adopted, the proposal will require packers to advertise and sell packages of animal bedding on the basis of the expanded volume of the bedding. Most packages of animal bedding are compressed during packaging and the expanded volume is the amount of product that consumers will recover through unwrapping and decompressing the bedding according to the instructions provided by the packer. See also Item 260-3 for proposed Test Procedures for Verifying the Expanded Volume Declaration on Packages of Animal Bedding.
NIST Handbook 133—“Checking the Net Contents of Packaged Goods”
Item 260-1 Chitterling Test Procedure
The L&R Committee is recommending for adoption a proposal that will add a test procedure and purge allowance to NIST Handbook 133 so the drainage equipment and methods used by state and local weights and measures officials are identical to those used by the Food Safety and Inspection Service of the U.S. Department of Agriculture in packing plants. This test procedure will also be used in verifying the amount of purge from beef tripe.Start Signature
