The path will be cut to two different depths, each for half of its length. Within 10 s of placing the specimen on the gage, make a reading asm follows: Care of Gage 6.

Rounded to nearest 5 m or 0. The values given in parentheses are for information only.

No further reproductions authorized. A viewing box is not mandatory for e1210, but if one is desired, a proposed design for a viewing box is contained in Appendix X1.

D — 05 Reapproved Standard Test Method for Fineness of Dispersion of Pigment-Vehicle Systems by Hegman-Type Gage1 This standard is issued under the xed designation D; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

The two edges on the 3.

D — 05 1-in. NOTE 6—Clear nishes may d11210 to be viewed at a lower angle or they may have to be opacied with a nely ground colorant or dye in order to see the particles better. Reduction should be in approximately the same proportion as the intermediate will be reduced in practice. Originally approved in This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.


Standard ASTM D1210

Summary of Test Method 3. Keeping the gage between the operator and the light source, make the angle between the face of the gage Protect gages that lie idle for extended periods of time from rust with an oil coating or oil d1120 wrap.

Three ratings are indicated: At this stage, it is necessary to be able to judge if the pigment agglomerates have been sufficiently broken up so as not to interfere with the smoothness of the nished coating lm. Use a solvent and a soft cloth.

Preferred calibrations are Hegman units and micrometers Note 1. This average is considered one reading. This area is equal to 6.

A number in parentheses indicates the year of last reapproval. These patterns are to be used for notation of frequency of particles and should not be interpreted according to the size of the dots.

There are 2 delimited sections on this gage, each of 6. Permission zstm to photocopy the standard may also be secured from the ASTM website www. This process allows the two test readings to be made with limited time lapses between completion of drawdown and reading.


The two protocols for reading the neness are: To be sure of an accurate grind reading, specimens must be free of air bubbles. Average the two readings to the nearest 14 Hegman units 5 d110.

The path shall be tapered uniformly in depth lengthwise from about 4 mils m at aatm mm from one end to zero depth at the other with intermediate calibrations in accordance with the depth at those points. When using the two-path gage, average the values in the two paths to the nearest 14 Hegman unit.

Report micrometer readings to the nearest multiple of 5 m and Hegman readings to the nearest 14 unit, When using the double-path gage, place material in both paths.
