Macro Vickers Hardness Tester – Standard Digital, Digital and Digital with CCD Optical Analysis Software

ISO 6507 is an international standard developed by the International Organization for Standardization (ISO). The full title of this standard is "Metallic materials - Vickers hardness test - Part 1: Test method."

ISO 6507-1 specifies the method for the Vickers hardness test for metallic materials. The Vickers hardness test is a common method for measuring the hardness of materials by pressing a diamond indenter into the surface of the material with a known force, and then measuring the size of the resulting indentation. This test method is widely used for measuring the hardness of materials with different thicknesses or for materials that are too small for other types of hardness tests.

ISO 6507-1 outlines procedures for conducting the Vickers hardness test, including requirements for the testing machine, preparation of test specimens, calibration, test force application, and measurement of the indentation size.

This standard is widely used in various industries, including metallurgy, manufacturing, engineering, and quality control, to assess the hardness of metallic materials.

Our Micro & Macro Vickers and Knoop Hardness Testers comply with ISO 6507.

ASTM E92 is a "Standard Test Method for Vickers Hardness of Metallic Materials" established by the American Society for Testing and Materials (ASTM) International.

This test method covers the determination of the Vickers hardness of metallic materials using a microindentation hardness testing machine. Vickers hardness is a measure of a material's resistance to indentation and is typically used for harder materials or when the test sample is thin.

In ASTM E92, the Vickers hardness is determined by measuring the diagonal lengths of the indentation left by a pyramidal diamond indenter. The hardness value is calculated based on the applied force and the surface area of the indentation.

Our Micro & Macro Vickers and Knoop Hardness Testers comply with ASTM E92.

ASTM E384 is a "Standard Test Method for Microindentation Hardness of Materials" established by the American Society for Testing and Materials (ASTM) International. This method is commonly used to determine the microhardness of materials, which involves measuring the resistance of a material to localized plastic deformation caused by indentation. Microindentation testing is often used for materials that are too small or too thin for traditional macroscopic hardness testing methods like Brinell or Rockwell hardness testing.

ASTM E384 provides guidelines for conducting microindentation hardness tests using various hardness testing machines, such as Vickers, Knoop, and instrumented indentation machines. The standard outlines procedures for sample preparation, calibration of the testing equipment, indentation procedures, and measurement of the hardness values.

This standard is widely used in industries such as metallurgy, materials science, engineering, and quality control to assess the mechanical properties of materials at small scales.

Our Micro & Macro Vickers and Knoop Hardness Testers comply with ASTM E384.

The Vickers method can be classified into three hardness testing load ranges: in the micro, low-load, and conventional (macro) hardness range depending on the ISO standard test force magnitude (and therefore on the Vickers Method, e.g., HV 0.01; HV 1; HV 10).

Depending on the appropriate load range, different applications exist for the Vickers techniques.

The benefits of the Vickers approach include:

Since the Vickers method covers the full hardness range, it can be applied to any materials and test specimens, from soft to hard.

There is just one kind of indenter that works with all Vickers techniques.

Since non-destructive testing is an option, the test specimen can serve additional functions.

The Vickers Hardness Test entails utilizing a diamond indenter to apply force (also known as a "load") to the test material in order to produce an indentation. The measurement of the specimen's hardness is determined by the depth of the indentation in the material. Generally speaking, the harder the object is, the smaller the depression. Depending on the force used to indent the test material, hardness testing can be divided into micro-indentation tests and macro-indentation tests. (Micro-indentation tests normally employ loads up to 200 gf; macro-indentation tests typically employ loads up to 1000 gf.) The two most popular tests that can be used for both micro- and macro-indentation are the Vickers and Knoop hardness tests.

By pressing the diamond indenter into the surface being tested, the test is carried out. The indenter has a square base, a pyramidal shape, and opposite faces that are at an angle of 136 degrees with one another. Loads typically range from 1 to 100 kgf. Typically, the entire load is applied for 10 to 15 seconds.

Micro hardness testing is one of the many applications for which the Vickers hardness test is appropriate. You may find a description of the Vickers hardness test, instructions on how to use it, and a catalogue of our Vickers microhardness testing equipment on this website.

The hardness depth of surface-hardened steels is frequently assessed via hardness testing. To do this, a succession of hardness imprints are made on the cross-sectioned sample, working their way toward the centre. The distance from the surface to the hardness limit (HL) is computed when the hardness evolution is shown on a graph.

Almost every type of material can be examined using microhardness procedures, including ceramics, metals, composites, and others. Vickers tests can be used for a variety of purposes because the test indentation is too small; examples include measuring individual microstructures, testing extremely thin materials like foils, determining the surface of one small part or several smaller parts, or determining the depth of case hardening by segmenting a portion and making a series of indentations to define a profile of the change in hardness.

According to the Vickers hardness test method, test material is indented using a diamond indenter in the correct pyramidal shape with a square base at an angle of 136 degrees with respect to a weight of 1 to 100 kgf. Typically, the full load is applied for 10 to 15 seconds.

Magnification is the process of enlarging something. Additionally, it means expanding the seeming size rather than the actual size. It is possible to measure this expansion.

Magnification Definition:

It describes the process of using lenses to enlarge an object visually. Additionally, the thing simply appears larger and does not actually become bigger. Additionally, this idea comes from two different forms.

First, use a microscope to magnify small things, and then a telescope (that makes a distant object appear closer and the images are more clear and more defined).

Additionally, both of these forms and tools use two distinct formulas. Additionally, microscopic magnification aids in our understanding of the composition and structure of items.

There are two types of magnification lenses Simple and Compound lenses.

NextGen’s Macro Vickers Hardness Tester – Analogue, Digital and Digital with CCD Optical Analysis magnification is 100X (for observation), 200X (for measurement), and can be extended to 400X.

The size of the diagonal impression that the indenter leaves behind is measured by the Vickers hardness test, an optical method. However, depth measurement methods gauge the size of the indentation made by the indenter (only Rockwell is standardized).

The depth of the indentation the indenter leaves on the surface of a workpiece (specimen) when applying a particular test force depends on how soft the material being tested is.

In order to measure the Vickers hardness, an ISO 6507-compliant pyramid-shaped indenter (with an interfacial angle of 136°) is pressed into a specimen (workpiece) with a specified test load beginning at 1 gf (HV).

The Vickers hardness (HV) is calculated by dividing the surface area of the remaining indent on the specimen by the test force (F in newtons N) (see formula below). The surface area of the remaining pyramidal indentation is determined using the average of the two diagonals because the base area of Vickers indents is normally not square (d1 and d2 in mm).

The standard specifies the Vickers hardness range (ISO 6507). Depending on the specimen material used and the test force, the Vickers hardness value might range from 1 to 3.000 HV.

Test duration for NextGen’s Macro Vickers Hardness Tester – Analogue, Digital and Digital with CCD Optical Analysis is 1-99 seconds.

For quick and easy analysis, the automated turret enables the exchange of the objective lenses and the indenter. The load, dwell period, and release phases of the macro testing force are all entirely automated. After the unit completes the test, the objective lens will automatically return to its original focus condition, which is over the indentation. This makes it possible to calculate the Vickers Hardness value by taking a quick measurement of the indentation's diagonals.

The test load for this Vickers method ranges from 1 gf according to ISO standards and from 1 gf up to 120 kgf according to ASTM standards. These standards demonstrate that this method may be used to measure hardness for all load levels, from micro to macro to low.

A material's resistance to permanent deformation, such as piercing or scratching, is referred to as hardness. One method of determining hardness is through static indentation tests. A cone, pyramid, or ball is driven into the material's surface to create a static depression. The hardness is determined by the relationship between the stress applied for a specific amount of time and the size or depth of the indentation. A square pyramidal diamond indenter with predetermined face angles is used in Vickers hardness testing.

The test should be run on a flat specimen with a polished or prepared surface for high-accuracy measurement. The amount of force applied determines the quality of the necessary surface. The indentation perimeter and depth must always be distinct under a microscope in all tests.

For NextGen’s Macro Vickers Hardness Tester NG-5 the Maximum Height of Specimen is 8.5cm and Maximum Depth is 11cm.

For NextGen’s Macro Vickers Hardness Testers NG-10, NG-30, NG-50 the Maximum Height of Specimen is 16cm and Maximum Depth is 30cm.

A flexible hardness test technique, the Vickers hardness test is used to measure both macro and micro hardness. It is appropriate for a variety of applications and materials and has a wide load range.

Many people believe that the Vickers hardness test is simpler to use than other hardness tests: The procedure can be carried out using a universal or micro hardness tester, the calculations necessary are independent of the indenter size, and the same indenter (a pyramidal diamond) can be used for all materials, regardless of hardness.

When you do a Vickers hardness test, your indentation will distort the surrounding material and change its properties regardless of the microhardness tester you choose. The Vickers hardness testing standards provide a specific spacing between multiple indentations in order to prevent erroneous interpretations of perceived hardness.

Volts are SI-derived units representing electromotive force, electric potential difference, and potential energy (symbol: V). One volt is the potential created when an electric current of one ampere spends one watt of energy between two points on a conducting wire. For every coulomb of charge that crosses the potential difference between two locations, one joule of energy will be transferred in its stead.

A power source's electrical potential, or, to put it another way, the amount of pressure required to get electrons to flow through an electrical connection, is 220V. There are several countries where 220V is the standard for residential power.

The International System of Units (SI) uses the hertz (symbol: Hz) as the unit of frequency, which is equal to one event (or cycle) per second. One hertz is equal to one second, according to the hertz, a SI-derived unit whose expression in terms of SI base units is s1.

ASTM E384 is the approved test method for determining a material's Knoop and Vickers hardness.

Test loads can range from 1 gramme to 1,000 grammes, despite the fact that they are typically between 100 and 500 grammes.

The Vickers indenter frequently produces an indentation that is geometrically equivalent at all test forces.

The Knoop indenter does not produce a geometrically similar indentation as a function of test force. Because of its rhombic shape, a Knoop indentation has a shallower indentation depth than a Vickers impression under the same test conditions. Therefore, it can be very useful to evaluate thin coatings or hardness gradients on sectioned samples using the Knoop indenter.

ASTM E140 can be used to convert Knoop and Vickers hardness values into other hardness scales.

This specification relates to the determination of the Vickers hardness of metallic materials with applied forces between 1 kgf and 120 kgf. Part B is covered by the validation of the Vickers hardness testing equipment. Additionally, section C talks about the standard test block calibration. All requirements are available from ASTM International.

This standard covers two classes of standardized tests: the Routine test (with routine accuracy) and the Verification, Laboratory, or Referee test (with a much higher degree of accuracy required). WMT&R specializes in the Referee Test.

In the Vickers Hardness Test, a small diamond indenter with an apical angle of 136 degrees is employed and is driven into the test material at a specific load. The resulting indentation is then measured from tip to tip along both axes. The average of the two axis readings is converted into a Vickers Hardness number using a formula, or more typically, a chart based on the formula. The test will yield the most accurate results if the specimen is subjected to the maximum load possible. A higher load results in a larger indentation, better measurement resolution, and more trustworthy data.

For the three separate test force ranges for metallic materials, including hard metals and other cemented carbides, ISO 6507 specifies the Vickers hardness test technique.

Principle: A diamond indenter is pressed into a test piece's surface in the shape of a right pyramid with a square base and a predetermined angle between opposing faces at the vertex.

The area of the sloped indentation surface, which is considered to be a right pyramid with a square base and the same angle as the indenter at the vertex, is divided by the test force to give the quotient, which is used to determine the Vickers hardness.

NOTE 1 The centre of the base and the apex of a right pyramid are in line.

NOTE 2 This document has incorporated hardness as appropriate.

LEDs are solid-state electronics that instantly transform electrical energy into a single colour of light. LEDs don't waste energy by converting it into heat that doesn't produce light since they use "cool" light-generating technology, in which the majority of the energy is provided in the visible spectrum. In contrast, an incandescent bulb emits the majority of its energy in the infrared (or non-visible) region of the spectrum. As a result, both HID and fluorescent bulbs generate a lot of heat.

LEDs don't just provide cold light; they also:

• Can be powered by a solar panel or even a portable battery pack.
• Can be included in a control system.
• Are compact, shock-resistant and vibration-resistant.
• Enjoy a quick "on-time" (60 nsec vs 10 msec for an incandescent lamp).
• Possess good colour resolution and a little or nonexistent shock danger.

A material's resistance to localized permanent deformation is gauged by its hardness. Plastic deformation is another name for permanent distortion. When a material deforms elastically, it does so only when force is applied; whereas, when a material deforms plastically, it does not change back to its previous shape.

Varied types of loading cause different behaviours from materials. For instance, a metal that can withstand a significant one-time impact very well could not behave the same way under continual loads.

To make an informed decision for the application, hardness testing must be done in each scenario.

Scratch, rebound, and indentation hardness are the three different types of hardness. Each sort of hardness can only be measured with a certain set of tools.

Also, the same material will have different hardness values for the types mentioned above.

The commonly used units for hardness measurement are:

• Brinell Hardness Number (HB)
• Vickers hardness number (HV)
• Rockwell hardness number (HRA, HRB, HRC, etc)

The minimum measuring unit of NextGen’s Macro Vickers Hardness Tester – Analogue, Digital and Digital with CCD Optical Analysis Software is 0.1μm.

A material's hardness is a quality, not a fundamental physical trait. Its definition is "resistance to indentation," and its measurement is the indentation's permanent depth.

Simply put, the harder the material is when tested with a fixed force (load) and a specific indenter. Using one of more than 12 distinct test procedures, the depth or area of the indentation is measured to determine the indentation's hardness.

Based on an optical measurement technique, the Vickers method. In order to create an indentation that can be measured and translated into a hardness value, a diamond indenter is used in the Microhardness Test Procedure, ASTM E-384. Although test samples must be well polished to permit quantifying the size of the impressions, it is particularly useful for testing on a variety of materials. For testing purposes, a diamond with a square base and a pyramidal shape is employed. Although "Macro" Vickers loads can be up to 30 kg or more, most loads are quite light, ranging from 10gm to 1kgf.
