Whenever a copy of any record is made in accordance with the provisions of section 47:2-5 of this title, and after it has been compared with the original, it shall be certified by the public official or board having the legal custody and control of the original. Thereafter, the copy shall be considered and accepted as evidence, and treated for all other purposes, as though it were the original.

The original shall be cared for and preserved, as if no copy had been made, for such examination as may be directed by an order of court in any action or proceeding in which the accuracy of the copy is questioned.
