Test de contrac\u021bie ASTM D4974:\u00a0<\/strong><\/p>\n Un specimen relaxat de fir sau cordon este supus c\u0103ldurii uscate pentru un timp specificat sub o tensiune specificat\u0103. Procentul de contrac\u021bie este afi\u0219at pe ecran \u00een timp ce specimenul este \u00eenc\u0103 sub tensiune \u0219i expus la c\u0103ldur\u0103.<\/p>\n Test de contrac\u021bie ASTM D5591:\u00a0<\/strong><\/p>\n O anumit\u0103 lungime de fir sau cablu este fixat\u0103 la o prindere, iar cel\u0103lalt cap\u0103t este montat cu o mas\u0103 de pretensionare, apoi masa este \u00eendep\u0103rtat\u0103, iar cap\u0103tul este conectat la o celul\u0103 de \u00eenc\u0103rcare. Dup\u0103 aceea, firul sau cordonul este expus la c\u0103ldur\u0103 uscat\u0103 la o temperatur\u0103 controlat\u0103.
