Summary This standard specifies requirements for instrumented nanoindentation test the ability of the instrument 's basic requirements and test methods, but also provides for instrument calibration and testing, pressure head, the requirements of the standard sample, and instrumentation flexibility and determination of indenter area function methods, and given to determine the hardness and materials parameters required for data analysis methods and precautions for using the indenter. This standard applies to test a variety of materials and thin film hardness, modulus, and its indentation depth range is usually nanoscale, which can also be extended to a few microns.

This standard by the National Standardization Technical Committee of nano technology (SAC/TC279) and focal points.

Restrictions optical microscope resolving power by conventional hardness test methods can not extend to the nanometer scale, based on the depth of measuring instruments
Of the nanoindentation technique emerged. The technology in terms of scale, the principles and parameters measured have undergone significant changes, mainly reflected in.
--- With real-time measurement and depth of the press-fit load replace residual indentation diagonal measurement of nano-scale to achieve a measure of operating and
Automation process;
--- Mechanics by establishing an appropriate model, you can get a variety of hardness and material parameters, such as pressed into modulus;
--- Can study the mechanical response of materials throughout the loading and unloading process.
In recent years, the rapid domestic nano-indentation test technology development, is becoming the most important means of nanomechanical characterization test field. However
And, using this technology affect the test, vulnerable equipment, environment, methods, sample and test personnel, and many other factors, which often leads to results
Comparability difference. Therefore an urgent need to regulate the instruments through standardized nano indentation test methods.
In 2002, ISO 14577-1.2002 "instrument metal hardness and materials parameters indentation test - Part 1. Test method
Law ", ISO 14577-2.2002" instrument metal hardness and materials parameters indentation test - Part 2. testing machines and school
Associate ", ISO 14577-3.2002" instrument metal hardness and materials parameters indentation test - Part 3. Calibration of reference blocks "(English
Chinese Version) released. In 2007, ASTME2546-07 "Instrumented indentation test procedures" release. The standard of written reference to the above criteria
Applicable sections, taking into account the future development trend of technology, two new appendices. Since the major domestic use nanoindentation instrument into
Instrumented indentation test line, therefore, the scope of this standard within the limits of such use of the instrument.
