Keeping the gage between the operator and the light source, make the angle between the face of the gage and the line of vision so that the image of satm uorescent tube appears in the material on the gage.
Within 10 s of placing ashm specimen on the gage, make a reading as follows: The arrow in each drawing represents the end point reading for that distribution. Rounded to nearest 5 m or 0. A 0 to 8 specksB 9 to 15 specksand C 16 or more specks. Summary of Test Method 3.

Replace or recondition unsatisfactory blades. Reduction should be in approximately the same proportion as the intermediate will be reduced in practice. In order that readings obtained with these arbitrary scales and modications can be reported in the preferred units, the approximate relationship of these scales to gage depth is shown in the following example: Avoid tapping or scratching with other metal.
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. NOTE 7—It is suggested that each side be counted only to a maximum of Therefore, before testing, high-viscosity intermediate specimens that have little ability to ow should be reduced with a compatible liquid.

To be sure astn an accurate grind reading, specimens must be free of air bubbles. The two edges on the 3. Last previous edition approved in as D — Signicance and Use 4.
These patterns are to be used for notation of frequency of particles and should not be interpreted according to the size of the dots. It is preferable to scan from the shallow end toward the deep end, since this allows the operator to just decide when the dense pattern breaks, rather than trying to decide whether Copyright by ASTM Int’l all rights reserved ; Sun Jul 4 NOTE 1—Several asstm scales and modications of the gage are used by industry.
When using the two-path gage, average the values in the two paths to the nearest 14 Hegman unit.
Keeping the gage between the operator and the light source, make the angle between the face of the gage The path will be cut to two different asgm, each for half of its length. No further reproductions authorized.
NOTE 3—For this test method to function properly, the pigment particles in the specimens to be tested should be free to settle to the bottom of the gage channel after the drawdown. Rocking the scraper forward or back will reveal poor contact due to wear or warpage.
