A grand average can be calculated by taking the average of the set means in this case. If another method of? The values in Table 2 do not correspond to theoretical constraints; but, by using these values, empirical observations have shown that the method is optimized asmt a given precision.

Guidelines are given in 9. Thus, the method can be applied to any type of solid material from which adequate two-dimensional sections can be prepared and observed. NOTE 1— Table 1 gives the appropriate multiplying factors t for any number of?

Guidelines are given in 7. E56-211 are given e52-11 Section 8. The value of the multiplier, t, can be found in Table 1. Table 2 provides guidelines for this selection.

Diagrams of two possible grids, one with a circular pattern and one with a square pattern, which are recommended for use, are shown in Fig.

No other units of measurement are included in this standard. To aztm bias, questionable points should be counted as one half. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. The use of —point grid facilitates easy volume percent calculations. Any number of clearly distinguishable constituents or phases within a microstructure or macrostructure can be counted using the method.

A number in parentheses indicates the year of last reapproval. However, it should be recorded since it may have an effect upon the precision obtained. Two common types of grids circular or square array are shown in Fig. Point counting measurements should be completed on different? Historical Version s – view previous versions of standard.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. This can be achieved by using either a circular grid or a square grid placed at an angle to the microstructural periodicity.
