1.1 The purpose of this practice is to present concepts necessary to the understanding of the terms ‘precision’ and ‘bias’ as used in quantitative test methods. This practice also describes methods of expressing precision and bias and, in a final section, gives examples of how statements on precision and bias may be written for ASTM test methods.<\/p>\n

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.<\/p>\n
