Title: Transfer Reference Meters for Disseminating NIST Calibration Scale for Field Meters Used to Verify Electric Vehicle Supply Equipment (EVSE) Accuracy

Requesting Lab: Physical Measurement Laboratory, Applied Electrical Metrology Group

I. BACKGROUND INFORMATION

The National Institute of Standards and Technology (NIST) requires the purchase of electronic components for the assembly of two transfer reference meters, which are needed to calibrate field meters used to test the accuracy of Electric Vehicle Supply Equipment (EVSE), also known as EV Fueling Systems or EV Charging Equipment. Two transfer meters are needed by the calibration lab and for conducting an international interlaboratory comparison. The calibration service by NIST is necessary to support the national EV charging infrastructure to ensure marketplace equity and consumer confidence.

The NIST, through the Applied Electrical Metrology Group, is tasked with disseminating standards for measurement of electrical energy dispensed by Electric Vehicle Supply Equipment (EVSE) to enable compliance with NIST Handbook 44. The Applied Electrical Metrology Group and OWM are conducting an international interlaboratory comparison to validate the calibration measurement results specific to EVSE metering, against other national metrology laboratories, as required by Mutual Recognition Agreement.

The purpose is to purchase the specified components needed to assemble two transfer reference meters which can be used to calibrate field meters for EVSE used by state metrologists. The transfer meters once assembled and calibrated by NIST, will establish traceability of electrical energy measurements to the SI, in compliance with NIST Handbook 44. These transfer reference meters will be used in an international interlaboratory comparison in order to validate the NIST calibration scale.

IV. DELIVERY TERMS

Delivery shall be not later than August 31, 2024, F.O.B Destination and shall occur in accordance with the delivery due dates provided in the above table.

FOB Destination means: The contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for any loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery. The contractor shall deliver all Line Items to:

National Institute of Standards and Technology Tom Nelson Bldg 220 Rm B152 Gaithersburg, MD 20899

V. INSPECTION & ACCEPTANCE

In addition to the inspection and acceptance terms articulated in 52.212-4, the Government reserves the right to perform such performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment that the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense.

NIST may choose at its discretion to forego this part of acceptance testing.

A visual inspection of the equipment will be performed by the NIST Technical Point of Contact (TPOC) to identify surface defects or any form of indication that any equipment was damaged during transport to NIST. The Government shall have sole discretion to require repair or replacement of damaged and/or nonconforming supplies at no cost to the Government. The Government at any time prior to acceptance shall reject the equipment due to defects and/or nonconformance. The vendor is responsible for latent defects discovered any time after final inspection. However, the extent of its liability shall be prorated over the useful life of the equipment.

Ownership of the equipment shall transfer to NIST upon acceptance by the Government.

The Government will test, inspect, and accept or reject the equipment within 10 working days of the receipt of the equipment unless otherwise indicated above. The Government reserves the right to conduct quality assurance testing to confirm that a given instrument(s) meets the manufacturer’s and/or the Government’s performance specifications. It is anticipated that the equipment will meet all manufacturer’s specifications and/or the Government’s performance specifications identified in the most recent operations and maintenance manual for each piece of equipment and/or in this document.
