{"id":854,"count":8,"description":"Rubber, vulcanized or thermoplastic. Determination of stress relaxation in compression. Part 1: Test at constant temperature\r\nThe Standard specifies two methods for determining the decrease in counterforce exerted by a vulcanized rubber or thermoplastic test piece that has been compressed to a constant strain and is thus maintained at a predetermined test temperature. The counterforce can be determined either by means of a continuous measurement system or a discontinuous measurement system.\r\nTwo test piece shapes are allowed: cylindrical test pieces and rings. Different test piece shapes and sizes give different results, and comparison of results should be limited to test pieces of similar size and shape. The use of annular test pieces is particularly suitable for the determination of stress relaxation in liquid environments.\r\nISO 3384-1 deals only with tests at constant or elevated temperature. Testing at temperatures below standard laboratory temperature is not specified. The methods have been used for low-temperature tests, but their reliability under these conditions has not been demonstrated.","link":"https:\/\/techlabsystems.com\/eng\/din\/1-2-3\/din-3384-1\/","name":"DIN 3384-1","slug":"din-3384-1","taxonomy":"din","parent":644,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/din\/854","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/din"}],"about":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/taxonomies\/din"}],"up":[{"embeddable":true,"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/din\/644"}],"wp:post_type":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/product?din=854"},{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/normas?din=854"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
