The Bank replaces damaged banknotes with new banknotes following the criteria below, provided that the two sides of the banknote are maintained, and the damaged banknotes are brought to the Bank's head office or branches by the possessor or his/her agent. Burnt banknotes are also exchangeable for new ones following the same criteria, provided that remaining ashes prove to be of banknotes.
A damaged banknote with two-thirds or more of the original remaining is exchanged at full face value.- Ссылка на первоисточник
