ASTM D6518-06e1<\/h3>\n

Historical Standard: Standard Practice for Bias Testing a Mechanical Coal Sampling System<\/h4>\n
\n

ASTM D6518<\/h4>\n

Scope<\/strong><\/p>\n

p>1.1 This practice presents sample collection and statistical evaluation procedures for testing mechanical sampling systems, subsystems, and individual system components for bias. It is the responsibility of the user of this practice to select the appropriate procedure for a specific sampling situation. <\/p>\n

1.2 This practice does not purport to define an absolute bias. Bias defined by this practice is the difference between the population mean of the mechanical sampler test results and the accepted reference value.<\/p>\n

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 limitations prior to use.<\/p>\n

Keywords<\/strong><\/p>\n
