It is mainly used to determine the flow curves of brittle building materials (concrete, polymer concrete, bricks, wood, foams, etc.), packaging materials (e.g. cardboard, foams) and metals (e.g. cast iron) and is used to assess the material behavior under uniaxial compressive stress, whereby right-angled prisms, cylinders or tubes can be used as test specimens.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Our services at a glance:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pressure test on the component<\/li>\n\n\n\n<li>Compression test according to DIN EN ISO 604 (plastics in general)<\/li>\n\n\n\n<li>Bending properties according to DIN 50106 (metals)<\/li>\n\n\n\n<li>Flexural strength according to DIN EN ISO 178 (plastics) \/ 3-point \/ 4-point bending test<\/li>\n\n\n\n<li>Bending test (Dynstat) according to DIN 53435 (plastics) \/ 2-point bending test<\/li>\n\n\n\n<li>DIN EN ISO 7438 \u2013 Metallic materials \/ Bending test<\/li>\n\n\n\n<li>ASTM B 312 \u2013 Standard test method for green strength of specimens compacted from metal powders<\/li>\n\n\n\n<li>DIN EN ISO 148-1 \u2013 Metallic materials \/ Charpy notched bar impact test<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Pressure test according to DIN EN ISO 604<\/h2>\n\n\n\n<p>To investigate the compression deformation behavior of test specimens under an external uniaxial compression load and to determine compressive strength, compressive modulus of elasticity and other aspects of the compressive stress-compression relationship, we use DIN EN ISO 604 for<br>\u2013 Rigid and semi-rigid thermoplastic injection and extrusion molding compounds, including filled and reinforced molding compounds<br>\u2013 Rigid and semi-rigid thermoset molding compounds, including filled and reinforced molding compounds and thermotropic liquid-crystalline polymers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Flexural properties according to DIN 50106<\/h2>\n\n\n\n<p>This standard applies to the pressure test on all metallic materials and is used to assess the strength and deformation behavior of the material under investigation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Flexural strength according to DIN EN ISO 178<\/h2>\n\n\n\n<p>The bending test according to DIN EN ISO 178 is used in particular to test brittle materials that cause metrological problems in tensile tests due to their failure behavior.<br>The principle of the bending test consists in the use of a two-part bending device in which the test specimen is clamped as a bending beam between two outer supports and loaded via one (3-point) or two (4-point) internal supports. It is tested at a constant speed until failure or until a specified deformation is reached, with the force applied and the deflection being measured.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Bending test according to DIN 53435 (Dynstat)<\/h2>\n\n\n\n<p>The bending test according to DIN 53435 (Dynstat) is used to characterize material properties in components made of plastic.<br>There are different types of bending tests, the sequence of which is similar and which differ in the type of specimen storage and the number of load applications. Various material parameters as well as the stress-strain curve of the bending stress can be determined from the recorded bending force and deflection values.<br>In the 2-point bending test, the test specimen is clamped at one end and loaded with a test stamp on the exposed side.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Examples of compression and bending tests<\/h2>\n\n\n\n<figure
