ASTM E727/E727M-08

Determining Bulk Density of Granular Carriers and Granular Pesticides

SIGNIFICANCE AND USE
These test method is designed principally with clay, corncob, nut shell, paper-based or sand granular carriers, and granular pesticide products, but need not be limited to these materials. There may be more appropriate test methods for other types of granular carriers or pesticide products. The differences in the following test methods are slight, but they offer a choice of a recognized test procedure.
SCOPE
1.1 This practice covers information for the design and operation of a program to monitor and control ongoing stability and precision and bias performance of selected analytical measurement systems using a collection of generally accepted statistical quality control (SQC) procedures and tools.Note 1
A complete list of criteria for selecting measurement systems to which this practice should be applied and for determining the frequency at which it should be applied is beyond the scope of this practice. However, some factors to be considered include (1) frequency of use of the analytical measurement system, (2) criticality of the parameter being measured, (3) system stability and precision performance based on historical data, (4) business economics, and (5) regulatory, contractual, or test method requirements.
1.2 This practice is applicable to stable analytical measurement systems that produce results on a continuous numerical scale.
1.3 This practice is applicable to laboratory test methods.
1.4 This practice is applicable to validated process stream analyzers.
1.5 This practice is applicable to monitoring the differences between two analytical measurement systems that purport to measure the same property provided that both systems have been assessed in accordance with the statistical methodology in Practice D 6708 and the appropriate bias applied.Note 2
For validation of univariate process stream analyzers, see also Practice D 3764.Note 3
One or both of the analytical systems in can be laboratory test methods or validated process stream analyzers.
1.6 This practice assumes that the normal (Gaussian) model is adequate for the description and prediction of measurement system behavior when it is in a state of statistical control.Note 4
For non-Gaussian processes, transformations of test results may permit proper application of these tools. Consult a statistician for further guidance and information.
