If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

Last previous edition E — This test method has been described 4 as being superior to other manual methods with regard to effort, bias, and simplicity. Thus, the method can be applied to any type of solid material from which adequate two-dimensional sections can be prepared and observed.
Any number of clearly distinguishable constituents or phases within a microstructure or macrostructure can be counted using the method.
Originally published as E — The equations for calculating these values are as follows: If no sample atm is indicated that is, the con? Guidelines are given in 7. Standard Test Method f Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement e52-11 such rights, are entirely their own responsibility.
Do not observe the image while translating to a new? A grand average can be calculated by taking the average of the set means in this case. This can be achieved by using either a circular grid or a square grid placed at an astj to the microstructural periodicity. Table 2 provides guidelines for this selection.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
ASTM E562 – 11
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 for a given precision. These values were calculated under the assumption that the features have a random distribution upon the metallographic section.
Improving the Volume Fraction Estimate A superscript epsilon e indicates an editorial change since the last revision or reapproval. The use of —point grid facilitates easy volume percent calculations. Repeated point count measurements on an individual micrograph is not allowed. In this case, more rigorous statistical signi?
