ASTM D1210 PDF

Tygobar This test method describes a way of making this judgment. NOTE 2—Wear or warpage of the scraper may be noted by facing the edge of the scraper down on the smooth level face of the gage, then inspecting the contact edge aastm means of a strong light, placed behind the gage. This process allows the two test readings to be made with limited time lapses between completion of drawdown and reading. Rocking the scraper forward or back will reveal poor contact due to wear or warpage. These patterns are to be used for notation of frequency of particles and should not be interpreted according to the size of the dots.

This process allows the two test readings to be made with limited time lapses between completion of drawdown and reading.

These patterns are to be used for notation of frequency of particles and should not be interpreted according to the size of the dots. Therefore, before testing, high-viscosity intermediate specimens that astj little ability to ow should be reduced with a compatible liquid. A 0 to 8 specksB 9 to 15 specksand C 16 or more specks. Keep the gage covered or encased at 2 5. The path will be cut to two different depths, each for half of its length.

Replace or recondition unsatisfactory blades. 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 4—Clear nishes may have to be viewed at a lower angle or they may have to be opacied with a nely ground aatm or dye in order to see the particles better.

At some point in this path, particles or agglomerates, or both, will become visible. Within 10 s of placing the specimen on the gage, make a reading as follows: Signicance and Use 4. This area is equal to 6. Be sure the gage surface d free of lint. 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. Precision and Bias The awtm edges on the 3.

There are 2 delimited sections on this gage, each of 6. Last previous edition approved in as D — A superscript epsilon indicates an editorial change since the last revision or reapproval. When using the two-path gage, average the values in the two paths to the nearest 14 Hegman unit. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Do not consider any reading for the reported neness when the aastm lapse exceeds 10 s. The two protocols for reading the neness are: Protect gages that lie idle for extended periods of time from rust with an oil coating or oil soaked wrap.

Exert upon the scraper only sufficient pressure to clean excess material from the face of the gage. Summary of Test Method 3. ASTM D It may also be used to assess the inclusion of particulates by a cleanliness or texture rating.

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. The values given in parentheses are for information only. Keeping the gage between the operator and the light source, make the angle between the face of the gage Three path widths are covered by this test method: Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

Report micrometer readings to the nearest multiple of 5 m and Hegman readings to the nearest 14 unit, This d has been asmt for use by agencies of the Department of Defense. Use a solvent and a soft cloth. Preferred calibrations are Hegman units and micrometers Note 1. NOTE 6—Clear nishes may have 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.

Current edition approved Feb. Average the two readings to the nearest 14 Hegman units 5 m. The two depths will be 3 mils, and 1 mil, or as agreed upon between the buyer and the seller. NOTE 7—It is suggested that each side be counted only to a maximum of Reduction should be in approximately the same proportion as the intermediate will be reduced in practice. A count is made of the particles deposited in the two delimited areas, and cleanliness texture reading is determined.

Three ratings are indicated:.
