Therefore, it is often carried out as part of an incoming goods inspection.<\/p>\n<h4>The Density Test<\/h4>\n<p>We determine the density of elastomers or thermoplastic elastomers using the Archimedes principle. These test methods are described in the standards DIN EN ISO 1183-1 or ISO 2781.<\/p>\n<p>A test specimen is first weighed in air and then in a liquid with a well-known density. Using the buoyancy of the test specimen in the different media, the density of the material under test can be calculated with special density scales.<\/p>\n<p>The density of an elastomer material is not only influenced by the base rubber, but also by all fillers and additives contained in the elastomer compound. Since the proportions and weights of the ingredients of an elastomer compound are subject to permissible tolerances depending on the formulation, there are typical density ranges for the individual elastomer families.<\/p>\n<p>For example, the typical density range of fluorocarbon rubber FKM is 1,90 \u2013 2,60 g\/cm\u00b3.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-1qtfk-2-d5d6c4b7831757519afdb5a48b38d40c\">\n@keyframes av_boxShadowEffect_av-1qtfk-2-d5d6c4b7831757519afdb5a48b38d40c-row {\n0%   { box-shadow:  0 0 0 0 rgba(164,164,164,0.4);
