If it is determined on standard specimens, it allows, together with other material characteristics, to identify formulations. Together with the measurement of density and component dimensions, hardness measuring is one of the three most important parts of an identity verification. It is therefore often carried out as part of an incoming goods inspection.<\/p>\n<h4>The Hardness Test<\/h4>\n<p>There are different test methods to measure the hardness of a material. The selection of the appropriate measuring method depends primarily on the type of material and the geometry of the test specimen and is also determined by the degree of hardness to be expected.<\/p>\n<p>For hardness testing of elastomers and thermoplastic elastomers, depending on the basic hardness and geometry of the test specimen, the hardness measurement methods in accordance with Shore and IRHD are predominantly used. Therefore, we at Elastomer Institut Richter test exclusively using these methods.<\/p>\n<\/div><\/section><\/div>\n\n<\/div><\/div><\/div><!-- close content main div --><\/div><\/div><div id='av_section_4'  class='avia-section av-klm050jf-13-ec549a29ce07a5e28f82e1d168d3a4ef main_color avia-section-large avia-no-border-styling  avia-builder-el-13  el_after_av_section  el_before_av_section  no-padding-top acc avia-bg-style-scroll container_wrap fullsize'  ><div class='container av-section-cont-open' ><div class='template-page content  av-content-full alpha units'><div class='post-entry post-entry-type-page post-entry-3905'><div class='entry-content-wrapper clearfix'>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-1efst-8802404aeff588d61c322b982fa0e1c6\">\n.flex_column.av-1efst-8802404aeff588d61c322b982fa0e1c6{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-1efst-8802404aeff588d61c322b982fa0e1c6 av_one_half  avia-builder-el-14  el_before_av_one_half  avia-builder-el-first  first flex_column_div av-zero-column-padding  '     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-km38ga7n-b0bbf760837148d8537bed151671bcb6\">\n#top .togglecontainer.av-km38ga7n-b0bbf760837148d8537bed151671bcb6 p.toggler{\nborder-color:#a3c54e;\n}\n#top .togglecontainer.av-km38ga7n-b0bbf760837148d8537bed151671bcb6 .toggle_wrap .toggle_content{\nborder-color:#a3c54e;\n}\n<\/style>\n<div  class='togglecontainer av-km38ga7n-b0bbf760837148d8537bed151671bcb6 av-elegant-toggle  avia-builder-el-15  avia-builder-el-no-sibling  toggle_close_all' >\n<section class='av_toggle_section av-6bo6wy-84c81ae2904098a8f4b51bdc812d1436'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-1' data-fake-id='#toggle-id-1' class='toggler  av-title-above av-inherit-border-color'  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-1' data-slide-speed=\"200\" data-title=\"Hardness in accordance with Shore A and Shore D\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: Hardness in accordance with Shore A and Shore D\" data-aria_expanded=\"Click to collapse: Hardness in accordance with Shore A and Shore D\">Hardness in accordance with Shore A and Shore D<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-1' aria-labelledby='toggle-toggle-id-1' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color av-inherit-border-color'  itemprop=\"text\" ><p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-2540 alignleft\" src=\"http:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/Shore-Haerte-300x210.jpg\" alt=\"\" width=\"300\" height=\"210\" srcset=\"https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/Shore-Haerte-300x210.jpg 300w, https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/Shore-Haerte-1030x721.jpg 1030w, https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/Shore-Haerte-768x538.jpg 768w, https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/Shore-Haerte-705x494.jpg 705w, https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/Shore-Haerte.jpg 1200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>Shore hardness measurements in accordance with DIN EN ISO 868, DIN ISO 7619-1 and ASTM D2240-00 are intended as material parameters for measurement on plane-parallel standard specimens.<\/p>\n<p>A test on elastomer components depends on the geometry and is often used, even if the result is the &#8220;apparent&#8221; hardness and this must be specified beyond the standard hardness or agreed with the supplier.

However, this should be specified and agreed with the supplier. The indenters are ball-shaped and differ in diameter depending on the method. The IRHD methods are designated as M, H, N or L. The microhardness method, IRHD M, is usually used to determine the hardness of small elastomer components. Other methods are hardly ever used.<\/p>\n<\/div><\/div><\/div><\/section>\n<\/div><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-1efst-9-86fdccf2b4d6ff0336b7db205630d262\">\n.flex_column.av-1efst-9-86fdccf2b4d6ff0336b7db205630d262{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-1efst-9-86fdccf2b4d6ff0336b7db205630d262 av_one_half  avia-builder-el-16  el_after_av_one_half  avia-builder-el-last  flex_column_div av-zero-column-padding  '     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-km38ga7n-8-266804424f51128a9f41eae3088f9e43\">\n#top .togglecontainer.av-km38ga7n-8-266804424f51128a9f41eae3088f9e43 p.toggler{\nborder-color:#a3c54e;\n}\n#top .togglecontainer.av-km38ga7n-8-266804424f51128a9f41eae3088f9e43 .toggle_wrap .toggle_content{\nborder-color:#a3c54e;\n}\n<\/style>\n<div  class='togglecontainer av-km38ga7n-8-266804424f51128a9f41eae3088f9e43 av-elegant-toggle  avia-builder-el-17  avia-builder-el-no-sibling  toggle_close_all' >\n<section class='av_toggle_section av-8ho9u-e9c9576cf1eb2624790fb50b872f68d4'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-3' data-fake-id='#toggle-id-3' class='toggler  av-title-above av-inherit-border-color'  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-3' data-slide-speed=\"200\" data-title=\"IRHD Universal Hardness with the LNP Micro Indenter\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: IRHD Universal Hardness with the LNP Micro Indenter\" data-aria_expanded=\"Click to collapse: IRHD Universal Hardness with the LNP Micro Indenter\">IRHD Universal Hardness with the LNP Micro Indenter<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-3' aria-labelledby='toggle-toggle-id-3' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color av-inherit-border-color'  itemprop=\"text\" ><p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-2539 alignleft\" src=\"http:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/LNP-Mikroindenter-300x210.jpg\" alt=\"\" width=\"300\" height=\"210\" srcset=\"https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/LNP-Mikroindenter-300x210.jpg 300w, https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/LNP-Mikroindenter-1030x721.jpg 1030w, https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/LNP-Mikroindenter-768x538.jpg 768w, https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/LNP-Mikroindenter-705x494.jpg 705w, https:\/\/elastomer-institut.de\/wp-content\/uploads\/2021\/08\/LNP-Mikroindenter.jpg 1200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>The micro indenter LNP works with highly sensitive force and displacement measurement and almost arbitrarily small indenters.
