Arkansas law, Act 112 of 2003, states that each owner of a bulk or liquefied petroleum gas metering device, pump or scale used for a commercial transaction must engage a registered service agent to inspect and test that device annually beginning January 1, 2004. Upon completion of a satisfactory inspection and test the registered agent will affix a yellow decal, and if applicable a yellow wire security seal, to the device to indicate to the public the suitability of the device for trade for the calendar year. A copy of the bureau approved inspection and test reports will be provided to the owner of the device. The fee, for this service, will be determined by the registered service agent.

Should the registered agent be unable to perform or complete a satisfactory inspection and test on the device the agent must immediately file a Form SA-1S, Equipment Non-Compliance Report, with the Bureau of Standards.
