PAT program report. Background and current status.
Appl Occup Environ Hyg 1992 Jun; 7(6):355-357
The Proficiency Analytical Testing (PAT) Program was described, and results of PAT Rounds 105 through 108 were discussed. PAT has been a collaborative effort of the American Industrial Hygiene Association and NIOSH to provide quality control samples to over 1400 occupational health and environmental laboratories in over 15 countries. The primary focus of the program has been to improve the performance of the laboratories. Laboratories have been evaluated on their reported results against an acceptable performance limit for each PAT program sample analyzed. There were 1445 laboratories enrolled in the PAT program with 1359 laboratories submitting results on Round 108. A total of 1406 were rated based on their performance over the last four rounds. PAT Round 109 was sent out on April 1, 1992. The organic solvents included were chloroform (67663), carbon-tetrachloride (507255), and 1,2-dichloroethane (107062). Metals in this round included cadmium (7440439), lead (7439921), and zinc (7440666). Silica (14808607) had a calcite background and the asbestos included was chrysotile (12001284).
