NEWMA 2013 Interim Meeting: NEWMA recommended this item be designated as a Voting Item and commented that the proposed changes will help clarify the intent of the WG’s original suggestion. At its 2014 Annual Meeting, NEWMA supported moving the item forward as a Voting item. The SWMA did not receive any comments opposing the item. There were comments that the electronic receipt recommendation may also be suited to the General Code as well. The SWMA supported this item as written. See previous Reports of the National Conference on Weights and Measures for additional history on this item. 330-5B VC UR.3.3. Computing Device. (This item was Adopted.) Source: NCWM Task Group on Retail Motor Fuel Dispenser Price Posting and Computing Capability (2013) Purpose: Refine the criteria in the LMD Code related to price posting and computing capability of RMFDs for post-delivery discounted transactions to more clearly reflect the recommendations of the NCWM Task Group on RMFD Price Posting and Computing Capability for the indication of the highest unit price. Item Consideration: paragraph UR.3.3.(c)(2) to recognize electronic receipts as follows: A dispenser used in an application where a price per unit discount is offered following the delivery is exempt from this requirement, provided the following conditions are satisfied: (1) the unit price posted on the dispenser and the unit price at which the dispenser is set to compute shall be the highest unit price for any transaction; (2) all purchases of fuel are accompanied by a printed receipt recorded by the system. for the transaction containing: The receipt contain: the product identity by name, symbol, abbreviation, or code number; transaction information as shown on the dispenser at the end of the delivery and prior to any discount including the: volume of the delivery; unit price; and total computed price of the fuel sale prior to post-delivery discounts being applied. an itemization of the post-delivery discounts to the unit price; and the final total price of the fuel sale.
The following is the table Mr. Karimov generated on LNG density changes using the NIST REFPROP database. Mr. Karimov noted that density changes to LNG are negligible at 120 K with changes in pressure from the base pressure of 27.765 psi up to 200 psi.

Regional Association Comments: CWMA supports the work of OIML and suggests this remain as a Developing item. WWMA thanks NIST for their work in the International arena and looks forward to future updates. FYI, the next OIML meeting will be in Vietnam in 2013. The WWMA recommended that the item remain as a Developing item.
Appendix B NIST Handbook 44 – Scales Item 320-3: Revision 2 Draft Tentative Code Applicable to Weigh-In-Motion Systems Used for Vehicle Enforcement Screening Weigh-In-Motion Systems used for Vehicle Enforcement Screening – Draft Code Application A.1. General. – This code applies to systems used to weigh vehicles, while in motion, for the purpose of screening and sorting the vehicles based on the vehicle weight to determine if a static weighment is necessary. A.2. The code does not apply to weighing systems intended for the collection of statistical traffic data. A.3. The code is intended for field enforcement use only. A.4. Additional Code Requirements. – In addition to the requirements of this code, Screening Systems shall meet the requirements of Section 1.10. General Code. S. Specifications S.1. Design of Indicating and Recording Elements and of Recorded Representations. S.1.1. Ready Indication. – The system shall provide a means of verifying that the system is operational and ready for use. S.1.2. Value of System Division Units. – The value of a system division “d” expressed in a unit of weight shall be equal to: 1, 2, or 5; or a decimal multiple or submultiple of 1, 2, or 5. Examples: divisions may be 10, 20, 50, 100; or 0.01, 0.02, 0.05; or 0.1, 0.2, 0.5, etc. S.1.2.1. Units of Measure. – The system shall indicate weight values using only a single unit of measure. S.1.3. Value of Other Units of Measure. S.1.3.1. Speed. – Vehicle speeds shall be measured in miles per hour or kilometers per hour.
