Abstract
Inventia se refera la o metoda de determinare a domeniului normal de variatie a echilibrului hidric al probelor de lemn, in baza careia se determinaun sir de caracteristici care sunt utilizate in autentificarea si studiile de compatibilitate a unor tratamente in operatiile de punere in opera a lemnului nou sau a unor lucrari de prezervare activasi restaurare a lemnului vechi. Metoda include prelevarea probelor de material, deshidratarea prealabila a acestora la o umiditate atmosferica de celmult 10% UR, pana la o masa constanta, hidratarea ulterioara a probelor la o umiditate atmosfericade cel putin 99%, pana la o masa constanta, cu cantarirea periodica, dupa care urmeaza deshidratarea la aceleasi conditii (UR<10%) pana la o masa constanta cu cantarire periodica, trasarea curbelor de hidratare si deshidratare, conform datelor obtinute la cantarire, determinarea domeniului normalde variatie a echilibrului hidric, care este cuprins intre curbele mentionate. Rezultatul consta indelimitarea riguroasa a domeniului normal de variatie a echilibrului hidric prin determinarea higroscopicitatii reversibile fiind utilizat un utilaj simplu, accesibil oricarui laborator, indiferent de dotare.
