Materia\u0142y te s\u0105 testowane w celu oceny ich w\u0142a\u015bciwo\u015bci skurczowych, zwykle wykorzystywanych do kontroli procesu lub zapewnienia jako\u015bci w produkcji.\r\n<h3>Proces testowy<\/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>Interpretacja wynik\u00f3w testu<\/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\/pl\/kategoria-produktu\/astm\/astm-d2732\/","name":"ASTM D2732","slug":"astm-d2732","taxonomy":"product_cat","parent":99,"meta":[],"_links":{"self":[{"href":"https:\/\/www.qualitester.com\/pl\/wp-json\/wp\/v2\/product_cat\/1044","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.qualitester.com\/pl\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/www.qualitester.com\/pl\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/www.qualitester.com\/pl\/wp-json\/wp\/v2\/product_cat\/99"}],"wp:post_type":[{"href":"https:\/\/www.qualitester.com\/pl\/wp-json\/wp\/v2\/product?product_cat=1044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
