Ces mat\u00e9riaux sont test\u00e9s pour \u00e9valuer leurs propri\u00e9t\u00e9s de r\u00e9tr\u00e9cissement, g\u00e9n\u00e9ralement utilis\u00e9es pour le contr\u00f4le des processus ou l'assurance qualit\u00e9 dans la fabrication.\r\n<h3>Processus de test<\/h3>\r\nA specimen is prepared, typically 100x100 mm, and carefully placed in a controlled temperature bath for 10 seconds to reach thermal equilibrium. During this time, the film undergoes unrestricted shrinkage. The dimensions before and after exposure are measured in both longitudinal and transverse directions. The percent shrinkage is calculated using the initial and final dimensions.\r\n<h3>Interpr\u00e9tation des r\u00e9sultats du test<\/h3>\r\nThe shrinkage percentage indicates the material's thermal response and its suitability for specific applications. Consistent shrinkage values help determine the stability and performance of the film during use.\r\n\r\n<\/div>\r\n<\/div>","link":"https:\/\/www.qualitester.com\/fr\/categorie-produit\/astm\/astm-d2732\/","name":"ASTM D2732","slug":"astm-d2732","taxonomy":"product_cat","parent":99,"meta":[],"_links":{"self":[{"href":"https:\/\/www.qualitester.com\/fr\/wp-json\/wp\/v2\/product_cat\/1044","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.qualitester.com\/fr\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/www.qualitester.com\/fr\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/www.qualitester.com\/fr\/wp-json\/wp\/v2\/product_cat\/99"}],"wp:post_type":[{"href":"https:\/\/www.qualitester.com\/fr\/wp-json\/wp\/v2\/product?product_cat=1044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
