Quality control sample means surplus proficiency test material, stable at least for the duration of the proficiency test, with assigned values and satisfactory ranges (±2 standard deviations for proficiency assessment) derived from the overall proficiency test statistics. “Reference Material” means quality control material that has undergone formal stability testing. The parameter values are derived from subsets of proficiency test data (ideally traceable to the International Standard). Parameter values are provided with associated uncertainties, derived from a combination of subsets of proficiency test data, homogeneity testing and stability testing.
