“Service agent” means a person employed by a service agency to repair a commercial device.

A Registered Service Agency is also defined as: A (Agency, RSA) is a company who is owned by a Sole 
Proprietorship, Partnership, Corporation, LP, LLC, or other business type that installs, 
services, repairs, or reconditions commercial weighing and measuring devices for payment. 

Who needs the services of a RSA?

Any who installs, maintains, and/or repairs EVFS/EVSE devices for commercial use must use a RSA to place the device into service. A device is considered for commercial use if it charges users by the kwh or by the hour.

EVFS/EVSEs to be used for commercial purposes may only be placed into service by 
the State or county Sealer of Weights and Measures or a Registered Service Agency 
(RSA).

What does “Placed in Service” mean?

“Placed in Service” means to permit the use of a device that has been tested and found 
to be “correct” (meaning that the device meets all of the specification and tolerance
requirements)

What testing equipment is needed to be an EVFS/EVSE RSA?

The field test standard must be able to measure AC and/or DC electrical power from the 
EVFS/EVSE at the vehicle connector plug. The test standard must be traceable to the 
National Institute of Standards and Technology (NIST) or an ISO/IEC 17025 accredited 
laboratory. The service agent must assure that the field standard specifications meet 
the specifications of the EVFS/EVSE under test.

Each service agency shall be responsible for compliance with the following:

Repairing or Placing Devices into Service. - Each service agency shall place into service, upon
