ASTM D6300-02

Standard Practice for Determination of Precision and Bias Data for Use in Test Methods for Petroleum Products and Lubricants

SCOPE
1.1 This practice covers the necessary preparations and planning for the conduct of interlaboratory programs for the development of estimates of precision (determinability, repeatability, and reproducibility) and of bias (absolute and relative), and further presents the standard phraseology for incorporating such information into standard test methods.
1.2 This practice is generally limited to homogeneous products with which serious sampling problems do not normally arise.
1.3 This practice may not be suitable for solid or semisolid products such as petroleum coke, industrial pitches, paraffin waxes, greases, or solid lubricants when the heterogeneous properties of the substances create sampling problems. In such instances, use Practice E 691 or consult a trained statistician.

INTRODUCTION
Both Research Report D02:1007, Manual on Determining Precision Data for ASTM Methods on

Petroleum Products and Lubricants (1) and the ISO 4259, benefitted greatly from more than 50 years
of collaboration between ASTM and the Institute of Petroleum (IP) in the UK. The more recent work
was documented by the IP and has become ISO 4259.
ISO 4259 encompasses both the determination of precision and the application of such precision

data. In effect, it combines the type of information in RR:D02–1007 regarding the determination of
the precision estimates and the type of information in Practice D 3244 for the utilization of test data.

The following practice, intended to replace RR:D02–1007, differs slightly from related portions of
the ISO standard. This new practice is consistent with the computer software, Calculation of Precision
