all of these properties together determine how reliably O-rings can perform their sealing task.  <\/p>\n<p>Even a single deficit is enough to significantly reduce the service life of a seal. Then, despite careful design, there is a risk of short maintenance intervals or sudden machine defects.  <\/p>\n<p>Quality control of O-rings is therefore an essential and ongoing task for manufacturers and suppliers.

Whether the O-rings supplied fulfill their part of the task can be checked primarily on the basis of these properties:<\/p><ul><li>Inner diameter<\/li><li>Cord thickness<\/li><li>Hardness<\/li><li>Material composition<\/li><li>Compression set<\/li><\/ul><div><strong>Inner diameter<\/strong><\/div><p>The inside diameter of O-rings, together with the groove base diameter, determines the elongation of a piston seal when installed.<\/p><p>It is crucial for the sealing effect that this is within the target range. For example, excessive elongation causes the cross-section of the O-ring to flatten. As a result, there may be less compression on the cylinder surface.<\/p><p>Z<span style=\"color: var( --e-global-color-text );\">Various measuring methods are available for determining the inside diameter. The range extends from simple measuring cones to laser scanning micrometers.<\/span><\/p><p><strong>Cord thickness<\/strong><br \/><span style=\"color: var( --e-global-color-text );\">Together with the inner diameter, the cord thickness describes the basic dimensions of an O-ring. The outer diameter of the sealing element is calculated from the inner diameter and the cord thickness. <\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">Accordingly, a piston seal has a direct influence on compression. Cord thicknesses can be measured using probes or laser scanning micrometers.<\/span><\/p><p><strong>Shore hardness<\/strong><br \/><span style=\"color: var( --e-global-color-text );\">Harder O-rings are better suited for use under high pressure. <\/span><span style=\"color: var( --e-global-color-text );\">There is a risk that the O-ring will be pressed into the sealing gap, especially if there is a combination of a large sealing gap width and high operating pressure. <\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">A harder O-ring can withstand this stress for longer without shearing off material, for example. The common measuring principle consists of a truncated cone that presses on the material. Its penetration depth provides information about the hardness of the material. <\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">The common Shore A and IRHD methods differ primarily in terms of the weight and shape of the test specimen. <\/span><span style=\"color: var( --e-global-color-text );\">While Shore hardness is used for standard samples, IRHD is more suitable for measuring finished parts.<\/span><\/p><p><span style=\"color: var( --e-global-color-text );\"> <strong>Material composition<\/strong><\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">The content of the polymer material in relation to other formulation components indicates how the\u00a0<\/span><span style=\"color: #fe5050;\"><a style=\"color: #fe5050;\" href=\"https:\/\/nh-oring.de\/en\/o-ring-bestaendigkeitsliste\/\" target=\"_blank\" rel=\"noopener\">media resistance<\/a>\u00a0<\/span><span style=\"color: var( --e-global-color-text );\">or temperature behavior of an O-ring.<\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">For example, the acrylonitrile content of NBR sealing elements varies between 18 and 50 percent. A higher compound content improves resistance to oil and fuels. <\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">If the acrylonitrile content decreases, the elasticity improves in return. For reliable sealing, it is therefore crucial to rule out excessive fluctuations in the formulation. <\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">The composition of a material sample can be examined using thermogravimetric analysis (TGA).<\/span><\/p><p><span style=\"color: var( --e-global-color-text );\"> <strong>Compression set<\/strong><\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">As far as the temperature behavior of O-ring materials is concerned, the <span style=\"color: #fe5050;\"><a style=\"color: #fe5050;\" href=\"https:\/\/nh-oring.de\/en\/?page_id=24071\" target=\"_blank\" rel=\"noopener\">compression set<\/a><\/span> (DVR) allows the best conclusions to be drawn. <\/span><\/p><p><span style=\"color: var( --e-global-color-text );\">To determine the value, the O-ring is stored in a temperature-controlled medium in a deformed state.

This is particularly useful when assessing O-rings. Users can deduce the base polymer and the composition of the respective O-ring from the density. In practice, this is an effective approach for incoming goods inspection. It is used, for example, to reliably detect incorrect deliveries and uncover recipe fluctuations.\n<\/li>\n<li><strong>Tensile strength<\/strong><br>Manufacturers specify the tensile strength of an O-ring as well as the density in the data sheet. It provides information on the force required to tear a sample. Except for unfavorable assembly processes, however, O-rings are hardly ever subjected to tensile strength in practice.\n<\/li>\n<li><strong>Tensile elongation<\/strong><br>This value indicates how great the elongation is at the moment a sample is torn.

However, the <sub>TR10<\/sub> test has also become established. A sample strip is frozen in a 100 percent stretched state. After release from the test fixture, it is observed how the sample returns to its original shape as the temperature equalizes.

In addition to the equipment, compliance with the respective measurement standard also has a considerable influence on the measurement results.  <\/p>\n<p>To ensure that the results are reliable and can therefore be used, for example, in contact with suppliers, the requirements for the number of repetitions, temperatures or properties of standard samples must be taken into account. In practice, this often proves difficult.<\/p>\n<p>In addition, the conflict between specifications on standard samples and measurements on the finished O-ring remains.  <\/p>\n<p>Many relevant properties of O-rings are subject to shape dependency, so that measured finished part values cannot be easily compared with data sheet specifications for standard samples.  <\/p>\n<p>This is why more and more users of O-rings are specifying the properties of the finished part. For example, ISO 3601 also provides for hardness and strength.  <\/p>\n<p>In addition, users of O-rings can reduce their own measurements by working with reliable suppliers who in turn ensure stable product quality.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-80e061d elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"80e061d\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-ef1793f\" data-id=\"ef1793f\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-b51227b elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"b51227b\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-b1e799d\" data-id=\"b1e799d\" data-element_type=\"column\" data-e-type=\"column\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-616620c elementor-widget elementor-widget-text-editor\" data-id=\"616620c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>&#8220;I am convinced that we should share our knowledge with the world.
