ASTM D1210

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. This area is equal to 6. 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.

Report micrometer readings to the nearest multiple of 5 m and Hegman readings to the nearest 14 astk, The two depths will be 3 mils, and 1 mil, or as agreed upon between the buyer and the seller. Rounded to nearest 5 m or 0.

A count is made of the particles deposited in the two delimited areas, and cleanliness texture reading is determined. C Federation of Societies for Paint Technology scale. NOTE 1—Several arbitrary scales and modications of the gage are used by industry.

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: Do not consider any reading for the reported neness when the time lapse exceeds 10 s. Keep the gage covered or encased at 2 5. Current edition approved Feb.

NOTE 4—Clear nishes may have to be viewed at a lower angle or they wstm have to be opacied with a nely ground colorant or dye in order to see the particles better. When using the two-path gage, average the values in the two paths to the nearest 14 Hegman unit.

Replace or recondition unsatisfactory blades. Average the two readings to the nearest 14 Hegman units 5 m. Therefore, before testing, high-viscosity intermediate specimens that have little ability to ow should be reduced with a compatible liquid.

Signicance and Use 4. NOTE 7—It is suggested that each side be counted only to a maximum of When using the double-path gage, place material in both paths. Precision and Bias Rocking e1210 scraper forward or back will reveal poor contact due to wear or warpage.

The two edges on the 3. A number in parentheses indicates the year of last reapproval.

NOTE 2—Wear or warpage of the scraper may be noted by facing the edge of the scraper down on d12210 smooth level face of the gage, then inspecting the contact edge by means of a strong light, placed behind the gage. Determine the point in the particle distribution that approximates a similar end point pattern to that of the atm standards. 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.

Reduction should be in approximately the same proportion as the intermediate will be reduced in practice.

Any light coming through between scraper and gage face shows that the scraper has been damaged and is not satisfactory for use. NOTE 5—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.

The interlaboratory test results from the previous revision of this method are valid, but because of the discrete nature of the data, a new analysis of the values needs to be done. Three d12210 are indicated: At this stage, it is necessary to be able to aatm if the pigment agglomerates have been sufficiently broken up so as not to interfere with the smoothness of the astk coating lm. 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.
