Of course, hardness testers are not all the same. And each one is suitable for a specific application. We invite you to keep reading to learn more about these non-destructive testing instruments.<\/p>\n\n
Click here<\/a><\/strong>\u00a0to check the Linkedin poll.<\/p>\n\n According to the famous encyclopedia\u00a0Britannica<\/strong><\/a>, a hardness tester is a \u201cdevice that indicates the hardness of a material, usually by measuring the effect on its surface of a localized penetration by a standardized rounded or pointed indenter of diamond, carbide, or hard steel.\u201d<\/p>\n\n Simply put, hardness testers are\u00a0non-destructive testing instruments<\/strong>\u00a0that\u00a0allow you to determine<\/strong>, based on the applicable standard,\u00a0the value of hardness of different materials<\/strong>, including, but not limited to:<\/p>\n\n The typical hardness test involves\u00a0an object called indenter<\/strong>\u00a0which is\u00a0pressed on and into the surface of the material being tested<\/strong>.<\/p>\n\n The indenter must have specific dimensions and must be loaded with a specific pressure depending on the type of tester.<\/p>\n\n Afterwards,\u00a0the hardness is determined by measuring the depth of the penetration or the area of the indentation.<\/strong>\u00a0Measuring one or the other will depend on the type of\u00a0hardness test<\/strong>\u00a0being performed. The most common ones include:<\/p>\n\n Knowing the hardness of the materials used on a piece or structure is important for various reasons.<\/p>\n\n First of all,\u00a0hardness testing allows you to assess important properties such as strength, ductility and wear resistance.<\/strong><\/p>\n\n Therefore,\u00a0with the information obtained, it is easy to determine whether the material is suitable for the application at hand or not<\/strong>\u00a0and whether further surface treatment is necessary to achieve the desired results.<\/p>\n\n Also,\u00a0it can be used to verify the quality of the material and determine if maintenance is required.<\/strong><\/p>\n\n As mentioned above, there are different hardness testers for different applications. So, let\u2019s take a look at the most common ones.<\/p>\n\n As the name suggests, these testers are based on the\u00a0Leeb hardness test<\/strong>\u00a0as defined in the ISO 16859 and ASTM A956 standards. It is a dynamic test method where\u00a0the ratio of rebound velocity to impact velocity of a moving impact body is used to determine the hardness.<\/strong><\/p>\n\n Leeb hardness testers\u00a0are usually employed for testing various metals and alloys<\/strong>, and they are a great choice when checking incoming and outgoing goods, for quality control activities, and maintenance of structures\u00a0and workpieces subject to wear.<\/strong><\/p>\n\n SAMA Tools\u00ae<\/strong> offers you 3 different models of rebound hardness testers:<\/strong><\/p>\n\n Similar to the previous type, these instruments are named after the hardness test that they perform,\u00a0the Barcol test<\/strong>.<\/p>\n\n This test is usually used\u00a0on softer materials such as aluminum, aluminum alloys and some plastics.<\/strong>\u00a0It was previously known as Barber-Colman Impressor since Walter Colman developed this test as a portable method during the World War II.<\/p>\n\n The process uses the indenter or \u201cimpressor\u201d to press on the material and measure how deep the tip of it penetrates.<\/p>\n\n We offer\u00a02 Barcol hardness tester models<\/strong>:<\/p>\n\n This simple model of hardness testers allows to measure\u00a0the hardness of soft materials such as soft steels, aluminum, brass and copper.<\/strong>\u00a0Moreover, it can be applied on different geometries and very small thickness values.<\/p>\n\n The values obtained can be easily converted to the common scales, including Vickers, Rockwell and Brinell.<\/strong><\/p>\n\n We offer\u00a03 versions<\/strong>\u00a0of the Webster hardness tester:<\/p>\n\n The main difference is the range of thickness and diameter they can be applied on.<\/strong><\/p>\n\n By definition, we can easily conclude that the process to perform a hardness test with a Shore hardness tester is very similar to the one with the Barcol tester.<\/p>\n\n There are different scales for Shore testing,\u00a0 the most common ones being\u00a0the Shore A scale for soft elastomers like rubber, and Shore D for hard elastomers and other polymers like thermoplastics and thermosets.<\/strong><\/p>\n\n This makes Shore hardness testers a great option for quality control activities in\u00a0rubber and plastics industries and for maintenance on ring nuts and gaskets.<\/strong><\/p>\n\n We offer\u00a03 different versions<\/strong>\u00a0of the Shore hardness testers:<\/p>\n\n The last one in the list is the most powerful of all, since it can handle more than the two scales mentioned above, and it comes with many other interesting features.<\/p>\n\n We also offer special stands<\/strong>\u00a0for more accurate and repeatable results,\u00a0and Shore test blocks for verification and calibration purposes.<\/strong><\/p>\n\n The most specialized hardness testers in the market are usually bench hardness testers, since they\u00a0offer a higher accuracy and repeatability.<\/strong>\u00a0Therefore, they are the favorite option\u00a0for metrological laboratories<\/strong>\u00a0and applications which require the maximum of these two aspects.<\/p>\n\n These testers work with the indentation principle by applying a constant load over a specific period of time on an indenter which is in contact with the sample. They can use indenters of different sizes, shapes and materials, thus providing the possibility to work with different standards and scales with the same device.<\/p>\n\n We offer\u00a05 versions<\/strong>\u00a0of bench hardness testers, some of them are manually operated and others which are motorized. The versions are:<\/p>\n\n All of our bench hardness testers come with a diamond cone indenter and corresponding test blocks.<\/p>\n\n According to the poll, most of the participants<\/strong>\u00a0who claim to use it or have used it in the past, say they\u00a0have used the bench hardness tester.<\/strong>\u00a0This is followed by users of shore hardness testers and Leeb hardness testers. Last but not least are the Webster and Barcol hardness testers.<\/strong><\/p>\n\n The most common answers to\u00a0what it was used for:<\/strong><\/p>\n\n When selecting the best hardness tester for your needs, there are different things to consider.
