(b) A laboratory that conducts cigarette testing under this chapter shall implement a quality control and quality assurance program that ensures the repeatability of the testing results. The repeatability value may not be greater than 0.19. In this subsection,
- (1) “quality control and quality assurance program” means the laboratory procedures implemented to ensure that operator bias, systematic and nonsystematic methodological errors, and equipment-related problems do not affect the results of the testing quality control program;
- (2) “repeatability” means the range of values within which the repeat results of cigarette test trials from a single laboratory will fall 95 percent of the time.
