These test methods shall only be valid for microstructures containing outlier coarse grains, where their population is too sparse...

ASTM E1382 - Standard Test Methods for Determining Average Grain Size Using Semiautomatic and Automatic Image Analysis
These test methods are used to determine grain size from measurements of grain intercept lengths, intercept counts, intersection counts, grain boundary length, and grain areas.

ISO 643 - Steels - Micrographic determination of the apparent grain size
This International Standard specifies a micrographic method of determining apparent ferritic or austenitic grain size in steels. It describes the methods of revealing grain boundaries and of estimating the mean grain size of specimens with unimodal size distribution.

Three Basic Procedures for Grain Size Estimation
1. Comparison Procedure—The comparison procedure does not require counting of either grains, intercepts, or intersections but, as the name suggests, involves comparison of the grain structure to a series of graded images, either in the form of a wall chart, clear plastic overlays, or an eyepiece reticle. There appears to be a general bias in that comparison grain size ratings claim that the grain size is somewhat coarser (1/2 to 1 G number lower) than it actually is. Repeatability and reproducibility of comparison chart ratings are generally ±1 grain size number.
2. Planimetric Procedure—The planimetric method involves an actual count of the number of grains within a known area. The number of grains per unit area, NA, is used to determine the ASTM grain size number, G. The precision of the method is a function of the number of grains counted. A precision of ±0.25 grain size units can be attained with a reasonable amount of effort. Results are free of bias and repeatability and reproducibility are less than ±0.5 grain size units. An accurate count does require marking off of the grains as they are counted.
3. Intercept Procedure—The intercept method involves an actual count of the number of grains intercepted by a test line or the number of grain boundary intersections with a test line, per unit length of test line, used to calculate the mean lineal intercept length, ℓ. ℓ is used to determine the ASTM grain size number, G. The precision of the method is a function of the number of intercepts or intersections counted. A precision of better than ±0.25 grain size units can be attained with a reasonable amount of effort. Results are free of bias; repeatability and reproducibility are less than ±0.5 grain size units. Because an accurate count can be made without need of marking off intercepts or intersections, the intercept method is faster than the planimetric method for the same level of precision.
For specimens consisting of equiaxed grains, the method of comparing the specimen with a standard chart is most convenient and is sufficiently accurate for most commercial purposes. For higher degrees of accuracy in determining average grain size, the intercept or planimetric procedures may be used. The intercept procedure is particularly useful for structures consisting of elongated grains.
In case of dispute, the planimetric procedure shall be the referee procedure in all cases.
The standard grain size is divided into 12 grades. Grades 1 to 4 are coarse grains, grades 5 to 8 are fine grains, grades 9 to 12 are ultrafine grains.

Metallographic Image Analysis Software for Materials Research

iWorks M is a comprehensive microscope metallographic image analysis software for materials research. Including particle analysis, grain size analysis, cast iron nodularity analysis, non-metallic inclusions rating, rust grade analysis, phase analysis etc, It is a perfect metallurgical software which can support your work and make workflows more efficient.

Grain Analysis
According to the standard of ASTM E 112 (2000), iWorks software can measure Grain size and grain size number. You can select one method out of intercept method or planimetric method.

Features of Grain Analysis:
Users can measure easily and quickly through the most preferred method
Provides Intercept method: grain size number can be calculated as the average value, as the number of line intercepts according to international specifications.

Intercept method can be calculated directly, and is most commonly used.
ASTM grain size number is measured by the length of the line and the number of the detected intersection point
Provides Planimetric method : since using the average grain size and in accordance with ASTM E112 standard, so you can easily and quickly measure without boundary reconstruction procedures.
You can select one method out of Intercept method or Planimetric method.
Automatic measurements can be modified.- Provides Report Manager: measurement results and chart can be sent to  Excel.

Cast Iron Analysis
iWorks' Cast Iron Analysis is used for ductile irons and incorporates industry standards including ASTM A 247-40, ASTM E 2567-11, ISO 945-1:2008, ISO TR 945-2:2011, ISO 16112:2006, JIS G5502:1995, JIS G5502:2001, KS D 4302:2006 and KS D4302:2011. Graphite nodules can be identified and placed into shape and size classes. Moreover, the ferrite and pearlite content of the sample may be optionally assessed. Nodule and ferrite identification is performed simply by sophisticated image processing which allows the operator to review the results in seconds.

Phase Analysis
With the Phase Analysis tool, users can sort images by using Grayscale, RGB, HSB or YUV to achieve analysis on a whole image or a specified area of interest (AOI). It can determine the occurrence of these phases with reference to the overall image or to one of the selected phases.

Non-metallic Inclusions Rating
iWorks' Non-metallic Inclusions Rating function can be used with an automated materials microscope and high resolution digital camera to create an integrated systems solution. It allows the verification as per up to 8 standards ASTM E 45-97(2002), ISO 4967:1998(E), JIS G0555:2003 and KS D 0204:2007) for non-metallic inclusions in steel alloys.
