The ‘‘Examination Procedures for Price Verification’’ adopted by NCWM in Publication No. 19 (August 1995), or any subsequent amendment thereof, are hereby adopted as the specifications and tolerances of the Department with respect to commercially used UPC scanning systems and PLU devices.

Example: A certified UPC/PLU inspector shall evaluate ‘‘errors’’ and the ‘‘accuracy’’ of UPC scanning systems and PLU devices in accordance with the ‘‘Examination Procedure for Price Verification’’ in NCWM Publication No. 19 (August 1995), which requires that a UPC scanning system or PLU device have an accuracy rate of 98% or higher to ‘‘pass’’ an inspection.
