To a certain extent, the harder body produces an elastic deformation of the softer one.  <\/p>\n<p>The object then returns to its original shape after being relieved. If the deformation is plastic, the body retains part of the deformation even when the pressure is no longer applied.

This is initially good for the sealing effect, as it increases the compression. However, if the pressure is too great, the effect is counterproductive.  <\/p>\n<p>The O-ring moves to the side of the groove facing away from the pressure. The O-ring may then move into the sealing gap. This so-called gap extrusion can cause permanent damage so that the sealing effect of the O-ring is lost.  <\/p>\n<p>There are two measures available to the designer for media with high pressure: He can optimize the installation situation so that the sealing gap is as small as possible. Choosing an O-ring with a higher hardness also helps with this problem. In the case of dynamic seals, friction and wear of the O-ring also play an important role.

The test engineer does not usually use this method to test the hardness of the finished part.  <\/p>\n<p>Instead, a standard sample with defined dimensions is used. This measured value can be found later in the O-ring data sheet. There are two different variants, Shore A and D. For O-ring materials, the Shore A test is particularly applicable.<\/p>\n<p>The standard stipulates a specimen thickness of at least 6 millimetres for testing vulcanizates, such as O-rings. The conical test specimen acts on the sample for 3 seconds under spring force. The temperature also has an influence on the material behavior.  <\/p>\n<p>For this reason, a target temperature of 23 degrees applies, from which there should be no deviation of more than 2 degrees up or down.<\/p>\n<p>During evaluation, the tester converts the measurement result for the penetration depth. A depth of 2.5 millimeters corresponds to a hardness of 0 Shore A. If the sample leaves no impression at all, the hardness is 100 Shore A. Very hard materials reach 90 points. The Shore hardness of finished parts can also be measured. This applies at least if the cord thickness of the O-ring is over 3 millimeters.<\/p>\n<p>In the Shore D hardness test for tougher elastomers, key parameters change with the pressure and dimensions of the test specimen. Therefore, there is no linear relationship between the measured values for the two Shore hardnesses.

The method is primarily used to determine the hardness of prefabricated parts.<\/p><p>However, the IRHD measurement is not suitable for line thicknesses of less than 1.6 millimeters. In contrast to the determination of the Shore hardness, a significantly smaller spherical test specimen penetrates the O-ring here. The highest point in the cross-section of the O-ring should be the attachment point. After the test specimen has acted on the O-ring for 30 seconds, the operator can read off the hardness.<\/p><p>It is important to note that the hardnesses of an identical elastomer determined on standard samples and finished parts will almost always differ. In addition, the measurement results according to Shore A and IRHD-M cannot be converted into each other. This is true even though the results in the medium hardness range can be relatively close to each other.<\/p><p>This is due to the different measuring methods, but also to the shape-related deviations in the properties. Geometrically, the standard sample of a material and the O-ring as a finished part hardly have anything in common.<\/p><p>Different material thicknesses and the curved surface affect the measurement. As the O-ring cross-section decreases, the precision of the process decreases significantly.<\/p><p>Just as important is where the tester places the test specimen on the finished part. The many possible errors pose a major problem in hardness testing. The results are generally much less reliable than the other measurement methods.<\/p><p>A tolerance of 5 Shore A or IRHD hardness points upwards and downwards is therefore common.

Very good suppliers of O-rings set themselves apart from average suppliers by taking comprehensive measures to monitor series quality. In this way, they ensure that their products meet the requirements of demanding applications.  <\/p>\n<p>In addition to hardness, they also keep an eye on other material properties such as weight and tensile strength. In addition, there is the behavior of the O-ring at high and low temperatures and the interaction with test media. Only together do these tests provide a comprehensive picture of the O-rings.<\/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<section class=\"elementor-section elementor-top-section elementor-element elementor-element-bdc0e6d elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"bdc0e6d\" 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-2bdac89\" data-id=\"2bdac89\" 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-7aec51d elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"7aec51d\" 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-bd8075d\" data-id=\"bd8075d\" 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-2c56dfd elementor-widget elementor-widget-text-editor\" data-id=\"2c56dfd\" 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.
