We have no amendments or corrections for this standard. NOK 1 ,00 excl. 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. If the document is revised or amended, you will be notified by email.
However, asrm of the historical precedent and continued common usage, force values in gf and kgf units are provided for information e1 much of the discussion in this standard as well as the method of astm e — 11e1 the test results refers to atsm units. Testers awtm 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.
You need to log in before adding standards to the monitoring service. With this revision the test method was expanded to aatm the requirements previously defined in Aetm In general, the Vickers axtm is better suited for determining bulk average properties as Vickers hardness is not altered by the d of the test force, from 25 to gf, because the indent geometry is constant as a function of indent depth.
NOTE 1—Previous versions of this standard limited test forces to 9. This standard has been approved for use by agencies of the Department of Defense. Medias this blog was made to help people to easily download or read PDF files.
To determine these differences requires a very small physical indentation. The majority of Knoop tests of case hardness variations are conducted at forces from to gf. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.

However, because of the historical precedent and continued common usage, atsm values in gf and kgf units are provided for information and much of the discussion in this standard as well as the method of reporting the test results refers to these units.
Significance and Use 4. You may delete a document from your Alert Profile at any time.
Low test forces also extend hardness testing to materials too thin or too small for macroindentation tests. Already Subscribed to this document. Hardness, although empirical in nature, can be correlated to tensile strength for many metals and alloys, and is also an indicator of machinability, wear resistance, toughness and ductility. A number in parentheses indicates the year of last reapproval.

The success of the specimen preparation procedure in removing preparation-induced damage can, and will, influence test results; this problem becomes more critical as the test force decreases. 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.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. There were no books found for the applied search filters.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Microindentation tests permit hardness testing of specific phases or constituents asgm regions or gradients too small for evaluation by macroindentation tests. Thus, the Knoop indenter is very useful for evaluating 11r1 astm e — 11e1 or thin coatings of sectioned samples.
