Book Description
This publication provides guidelines for evaluating data from advanced mass calibrations and for establishing measurement assurance programs in precision mass calibration laboratories. The NIST Weights and Measures Division (WMD) will use these guidelines when evaluating advanced mass calibration data for State laboratories that request technical support, Recognition, and/or National Voluntary Laboratory Accreditation Program (NVLAP) accreditation.Advanced mass calibrations use weighing designs, such as those found in NBS Handbook 145 (SOP 4, 5), NISTIR 6969, Selected Publications, NBS Technical Note 952, and the NIST/SEMATECH e-Handbook of Statistical Methods that require the use of computer software (mass code) for the data reduction. These weighing designs are normally used when high precision (low uncertainty) mass measurement results are sought, although weighing designs can be used at any uncertainty level. The uncertainty reported using advanced weighing designs is based on the historically observed process of similar measurements and is very dependent upon correct procedures for defining these processes.

Book Description
This paper describes a new method for determining, improving, and controlling the measurement process errors (or measurement uncertainty) of a measurement system used to monitor product as it is manufactured. The method is called the Process Measurement Assurance Program (PMAP). It integrates metrology early into the product realization process and is a step beyond statistical process control (SPC), which monitors only the product. In this method, a control standard is used to continuously monitor the status of the measurement system. Analysis of the control standard data allow the determination of the measurement error inherent in the product data and allow one to separate the variability in the manufacturing process from variability in the measurement process. These errors can be then associated with either the measurement equipment, variability of the measurement process, operator bias, or local environmental effects. Another goal of PMAP is to determine appropriate re-calibration intervals for the measurement system, which may be significantly longer or shorter than the interval typically assigned by the calibration organization.
