Common use of Laboratory Standards Clause in Contracts

Laboratory Standards. A. General - Florida Power & Light (FPL) has available one or more watthour meters and/or watthour meter standardization systems used as basic reference standards, of capacity and voltage range adequate to test all portable standards used by FPL. B. Accuracy - Watthour meters or watthour meter standardization systems used as basic reference standards will not be in error by more than ± *** at 1.00 power factor or by more than ± *** at 0.5 lagging power factor, after the application of standard correction factors. C. Traceability to National Standards - Traceability of FPL’s basic reference standards to the national watthour standards is established annually using one of the following methods: 1. NIST MAP - FPL establishes traceability to the national watthour standards through the Measurement Assurance Program (MAP) of the National Institute of Standards and Technology (NIST). With this method, the transport standard is provided by NIST. 2. Independent Laboratory - FPL establishes traceability to the national watthour standards through an independent laboratory. With this method, the transport standard is provided by the independent laboratory, and is of the same nominal value and of quality equal to the basic reference standards used by FPL. FPL intends to utilize Radian Research, Inc. of Lafayette, Indiana as its independent laboratory. Radian Research meets all the Independent Standards Laboratory requirements of ANSI C12.1, and provides a level of accuracy comparable to NIST. Other laboratories meeting the requirements of ANSI C12.1 may be utilized in the future. D. Intercomparison Of Standards - The percent registration of each FPL basic reference standard watthour meter or watthour meter standardization system is compared against the percent registration of every other FPL basic reference standard watthour meter watthour meter or watthour meter standardization system at frequent intervals.
