Abstract
A quality assurance program was developed for the Proficiency Analytical Testing Program to guarantee a continuing high quality product and provide a measure of analytical reproducibility in the form of coefficients of variation. Specific steps taken to insure quality control in the areas of asbestos (1332214) sampling, metals, silica (14808607), and organic solvents were discussed. Preshipment letters were submitted to the Project Officer four times a year, summarizing SRI analyses of an appropriate number of samplings at each level, chosen at random from those planned for shipping to participating labs. Quarterly reports were submitted after sample delivery providing statistical details covering the analysis by SRI of an appropriate number of samples at each level chosen at random from those generated. These reports also included calculations of the precision and accuracy of the generated samples, along with the taken values and the number and composition of sample sets transmitted, descriptions of any problems encountered, and the solutions to these problems.
