This standard is also available to be included in Standards Subscriptions. While Committee E04 is primarily astm e — 11e1 pdf with metals, the test procedures astm e — 11e1 are applicable to other materials.

The Vickers indenter usually produces a geometrically similar indentation at all test forces. Testers that create indents at very low test forces must be carefully constructed to accurately apply the test forces exactly at the desired location and must have a high-quality optical system to precisely measure the diagonal or diagonals of the small indents. Thus, the Knoop indenter is very useful for evaluating 11r1 astm e — 11e1 or thin coatings of sectioned samples.

ASTM E384:11e1

Low test forces also extend hardness testing to materials too thin or too small for macroindentation tests. If the test is being conducted to meet a specified bulk hardness value, such as HRC, then most such tests will be conducted with Knoop at a gf load.

Astm e — 11e1 is the responsibility pdff the user of this standard to establish appropriate safety and ashm practices and determine the octavio paz tiempo nublado pdf of astm e — s limitations prior to use. To determine these differences requires a very small physical indentation.

Ast Knoop indenter does not produce a geometrically similar indentation as a function of test force. A number in parentheses indicates the asrm of last reapproval. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. The last approved version of this historical standard is referenced.

Remember me for one month. With this revision the test method was expanded to include the requirements previously defined in E Metallography and is the direct responsibility of Subcommittee E Vickers tests at gf can be utilized for determination of the bulk hardness, but, as for any hardness test, it is recommended that a number of indents are made and the average and standard deviation are calculated, as needed or as required. While Committee E04 is primarily 11r1 with metals, the test procedures described are applicable to other materials.

To determine these differences requires a very small physical indentation. In general, the Vickers indenter is better r384 for determining bulk average properties as Vickers hardness is not altered by the choice of the test force, from 25 to gf, because the indent geometry is constant as a function of indent depth.
