A Quality Hardness Tester Ensures Accurate Material Testing

Hardness is defined by ability of a material to resist deformation. In the manufacturing industry, it is important to test the hardness of various types of materials—right from metals to plastics. A specially manufactured machine called a hardness tester is employed for this purpose. This machine helps apply a particular amount of pressure on the material and tests the amount of resistance shown by the material. The higher the resistance, the harder the material is believed to be.

Hence, material testing is an important part of any manufacturing process. The same time, it is an integral part of the quality testing and assurance process. A few years ago, these testers were bulky machines that were not very used friendly. However, with the advancement of technology, portable hardness testers that have easy-to use features and display screens have been developed. This has made the testing of materials far more easy and accurate.

    Using hardness testers:

A hardness tester is used to measure the hardness as well as resistance of several materials such as metals, rubber, plastics, lead, soft films among other items. While it is easy to test the hardness of small objects or samples, the same is not true in the case of larger objects. That is why portable  hardness tester are becoming popular. They can be used in different places and moved from one place of the factory to another. The type and brand of tester that you choose should depend on the materials that you want to test for hardness. For this purpose, you should ideally consult a manufacturer or dealer of such equipment.

    Things to keep in mind while choosing a hardness tester:

The hardness testing machine should be replete with several latest features in order to carry out your testing tasks effectively. For instance, it should offer you a variety of scales that display the hardness values. It should also have certain preset functions for commonly tested materials (both metals and plastics). A good tester should also be able to offer you the best accuracy—right down till the last decimal. There are some testers that display the results in points, tenths and hundredths. In addition, a good tester should come with a due warranty and guarantee. This is the true mark of a quality product. In addition to all these material testing qualities, the tester should also be competitively priced.

If you keep these points in mind while purchasing a tester, you are more likely to make the right choice. It is important to check if a hardness tester has been manufactured in adherence to various industry standards such as ASTM e-18. Only then can you be assured of a dependable product.

More Information About Portable Hardness Tester

What is a portable hardness tester? Portable hardness testers have been around since the late 90's, with a vast offering of high tech, digital instrumentation. Small, compact and menu driven, these instruments have never been easier to use for unlimited types of applications. Hardness Testing is a widely used method for determining hardness of materials using test methods such as Vickers, Brinell, Knoop, Rockwell, Shore, Clark and IRHD. Portable hardness testers come in a variety of types with the ability to test most metals, alloys and plastics ranging from soft polymers and rubbers to engineering alloys designed for use in the most arduous conditions or most severe operating environments. In addition, Portable Hardness Testers equipment offers a quick and economical supplement to stationary hardness testing in the modern production process.

There are two basic methods of portable hardness testing that is accepted in the field today.

"Dynamic Impact" is based on the Leeb principle of hardness, developed by Dietmar Leeb in the 1970's. A spring loaded impact body is thrust to the test surface, effecting rebound. The speed of both the initial thrust and the rebound is measured in a non-contact mode. This is calculated as a Leeb hardness value and then automatically converted to Rockwell C, B, Brinell, Vickers and Shore Values. It has effectually brought easy, fast and accurate results to portable hardness testing.

"Ultrasonic Contact Impedance" is based on a 136 degree diamond at the end of a vibrating rod being depressed into the test surface at a fixed load. The difference in Ultrasonic vibration frequency is then calculated into a hardness value. The UCI test procedure is slower than the Dynamic Impact style, however the "UCI" method of hardness testing is portable, easy and accurate. It also has its own advantages when utilized for certain testing applications. UCI testers are not restricted to large mass items like dynamic type testers. These units can test metals as thin as 1mm and at a hardness value as low as 20HRC (75HB). They also excel at performing hardness tests on larger, harder metals as well. Another reason for the rise in popularity is due to the fact that the UCI method is categorized as "Non-Destructive". That translates into less scrap parts/ lower mfg costs due to necessary inspections.

Operation:

This sectional view shows the basic design principle of the Webster Hardness Tester. The different models vary only in penetrator and load spring design. These combinations give the ability to test a wide range of hardnesses and metal.

The penetrator housing, which contains the penetrator and load spring, slides vertically in the frame of the tester when pressure is applied to the handles. Only sufficient pressure is needed to "bottom" the lower face of the housing against the work. Resistance of the work to the penetrator causes the penetrator to recede into the housing against the spring pressure. The degree of penetration on the test specimen is indicated on the dial indicator sitting on top of the housing assembly. The load can be varied by adjusting the nut above the load spring, permitting the dial reading to be easily corrected against a test block of known hardness.

A penetration of 0.010 inch produces a full scale reading on the dial indicator. Therefore materials in the softer hardness range should be of sufficient thickness so that the anvil will not influence the test and produce an "anvil effect". In general, soft materials under 0.025 - 0.030 in thickness will not give true readings.

Leebs Rebound Type Portable Hardness Tester

A full range of versatile rebound-type portable hardness testers using the dynamic Leeb Rebound technique, conforming to ASTM A956 and DIN 50156 standards.Leeb technique often is considered a universal method for portable hardness testing. With the Leeb principle an impact body with a hard metal test tip is propelled by spring force against the surface of the test piece. Surface deformation takes place when the impact body hits the test surface, which will result in loss of kinetic energy. This energy loss is calculated by velocity measurements.When the impact body is passing the coil at a precise distance from the surface, a signal voltage is induced during the impact and rebound phase of the test. The voltages are proportional to the velocity.Signal processing by the electronics provides the hardness reading for display and storage.Leeb rebound type portable hardness testers also have certain limitations for minimum sample thickness, weight and surface finish requirements. For lightweight, thin or non-steel samples we can recommend our other type portable hardness testers to ensure high accuracy and repeatability.

DYNATEST SC Portable Hardness Tester

The purpose of developing this new instrument was to design a portable hardness tester applying a heavy load, comparable to standard Rockwell loads. Also an important fact was to avoid the testing results being influenced by deflection, elasticity or mass of the work piece.

All this has been achieved by development of a new dynamic system, which radically differs from the common models on the market where the test load, being applied by an impact, is not being precise but depends on the reaction it gets; for this reason, these systems can be used only for testing considerable masses that are free of deflection.

With DYNATEST SC, on the contrary, the load acts progressively on the indenter in a very short time and without any impact.

This new system make use of the characteristics of an elastic component, which from load at zero progressively reaches the maximum load and then returns to zero. This component is previously compressed, and then during testing it acts on the penetrator. Thanks to this method, the test load is definite, as it is not produced by an impact but given by the characteristics of the elastic component. In this way the test result is not influenced by any deflection of the work piece.

DYNATEST SC is not influenced by the conditions of the surface to be tested and can be used simply by pressing it on the test surface.

DYNATEST SC enables the users to

Select hardness scale of your choice
Find the minimum measurable thickness
Correct the hardness curve in presence of known values - set + and - tolerance
Perform up to 1000 tests and have them printed afterwards

Choosing the Right Portable Hardness Tester

Hardness testers are primarily used to test the characteristics of a newly designed material or hardness testers are used as a quality check to assure that samples of newly developed products made from material such as rubber, steel and metal meet critical hardness standards. Sometimes the samples that need to be tested are too large to be tested using standard testing machines therefore portable hardness testers are becoming more popular when testing larger samples of material.

Portable hardness testers come in various makes and models. These various makes and models usually differ in the materials that they test. They may range in price from a few hundred dollars up to a few thousand dollars based on all of the machines functions. When choosing the right one it is extremely crucial to know the types of materials that you plan on testing. Portable hardness testers are able to test materials like soft films, rubber, lead, steel, soft metals and hard metals. The majority of these testers are primarily used to test metal hardness.

Understanding the various functions of these testers will help when it comes down to choosing which tester is right for you. After planning on which material you will be testing, next is figuring out how much you are willing to pay and how often will you be testing materials. Generally if you don't plan on using the hardness tester that much than a cheaper model with less functions should be all that you really need. The cheaper models are as accurate as the more expensive digital models. The cheaper models do not come with a digital display but they do run on batteries and their results are produced on a scale display. The more expensive models are generally manufactured to be used for commercial purposes, therefore they offer many more functions. These more expensive models will provide the same accurate results as the less expensive models but they are typically a little faster. The more expensive models also have functions to test a larger variety of materials, they also take less time to provide results and some models also come with a small printer to print out your results.

Knowing the materials you need to test and how often you will be testing these materials will play a key role on how much you should spend when choosing the right one. Considering there are so many options out there when purchasing a portable hardness tester it is extremely beneficial to do a little research on which tester is right for you and your needs.

What is a Portable Hardness Tester?

A portable hardness tester allows you to test the hardness of a metal without having to transport the metal to a large stationary machine. A portable hardness tester makes testing metals for your customers' orders much easier or for testing metal before using it to create your parts. A portable hardness tester for Rockwell testing is a small hand-held tester with an "impact device" attached that sends the information back to the computer where a mathematical formula determines the hardness of your metal. This is vital because your metals must have a specific hardness value in order to be used for a particular application. Popular portable hardness testers are manufactured by Phase II and Mitutoyo. The most popular and versatile portable hardness tester for Brinell testing is the King portable hardness tester.

What are Hardness Test Blocks?

Hardness test blocks, traceable to the National Institute for Standards and Technology (NIST), are manufactured by a number of American hardness test block manufacturers such as WESTport Corporation. The different hardness test block types are Rockwell, Brinell and Microhardness test blocks (also referred to as to as Knoop and Vickers test blocks). These hardness test blocks help you to measure your metals against a standard. Hardness test blocks are calibrated to a particular hardness value and verify the accuracy of your portable hardness tester or bench model hardness tester. This verifies that your measurements are in compliance with industry standards.

What are Special Taps?

Special taps come in a variety of types such as high speed steel, carbide, cobalt, taper, plug, bottom, fluteless, or spiral flute taps. Special taps are a cutting tool that cuts internal threads and are manufactured in compliance with specifications from ANSI standards (American National Standards Institute). Blank dimensions refer to the steel cylindrical blank from which special taps are manufactured. Special taps may be different from standard tap design criteria as it relates to thread type, size, shape, number of threads per inch and so on.

What is a Durometer?

A Durometer is used to measure the hardness of non-metallic materials, such as rubber, plastic, foam, wood, etc. A durometer works by measuring the depth of an indentation in the material created by a standardized given force. The basic durometer test requires applying the force in a consistent manner, without shock measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the specified time and then calculated. There are several scales of durometer, used for materials with different properties. The two most common durometer scales are the ASTM D2240 type A and type D scales. The A durometer scale is for softer plastics, while the D durometer scale is for harder ones. However, there are a total of 12 durometer scales; types A, B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R. Each scale results in a value between 0 and 100, with higher values indicating a harder material.

The experts all have something to say about the economy for the upcoming year. There are as many opinions about what is going to happen as there are people that have these opinions. Many of the experts say the economy is beginning to recover and I am inclined to agree with them. Things are better than they were a year ago and they will continue to see a slow upward progression.

The best way a person can deal with a poor economy is to do everything we can to be prepared. One person cannot control the economy, but they can control their own destiny. The best thing a person can do to prevent financial distress is to live below their means and use the excess income to prepare yourself for times of economic down turn.

It does not necessarily take a recession to put you in a poor financial situation. It is actually times of prosperity that cause the problem. Many people spend money they don't have without thinking about it, by using credit cards and home equity loans. It is the times of recession that make this mindless spending more apparent.

The past several years have been a wake up call to many individuals. The best thing people can do is learn from it and make changes that will help them in the future. Begin by developing a debt management plan that will help you pay off your debt, if you have consumer debt. Before you buy, take time to decide if your purchase is a "need" or a "want" and how essential it is that you have this item.

Once you get a plan in place for debt elimination, begin thinking about building wealth. There is a lot of information about preparing yourself for a financially stable future. Become an expert in wealth building and pick and implement a plan that fits your personality. This is a challenge that may take several years, but it will be well worth it in the end.
