Forces are measured to calculate static (force to start motion) and kinetic (force during motion) coefficients\u200b.\r\n<h3>ASTM D1894 Test Result Interpretation<\/h3>\r\nThe coefficients of friction are derived as the ratio of the pulling force to the sled's weight, providing insights into the material's surface interactions and suitability for applications\u200b.","link":"https:\/\/www.qualitester.com\/el\/product-category\/astm\/astm-d1894\/","name":"ASTM D1894","slug":"astm-d1894","taxonomy":"product_cat","parent":99,"meta":[],"_links":{"self":[{"href":"https:\/\/www.qualitester.com\/el\/wp-json\/wp\/v2\/product_cat\/106","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.qualitester.com\/el\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/www.qualitester.com\/el\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/www.qualitester.com\/el\/wp-json\/wp\/v2\/product_cat\/99"}],"wp:post_type":[{"href":"https:\/\/www.qualitester.com\/el\/wp-json\/wp\/v2\/product?product_cat=106"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
