New NOVO Test paper for deacidification

For more than a decade mass paper deacidification has been the essential conservation procedure.

Now, with the DIN recommendation the first step towards standardization in the process of deacidification has been made. It is now necessary that this document is also used as the basis for deacidification tenders being opened.

The publication of the "Recommendation how to successfully examine the processes of deacidification treatment for printing and writing papers" which was released by the German Institute of Norm Standardization e.V. (DIN)*, has for the first time given archives and libraries a guidance tool enabling them to implement and control proper deacidification methods. You receive with the fulfilment of the DIN recommendation, an automatic guarantee for the desired/ordered requirements.

Conversely, the deacidification provider has the possibility through the application of the DIN recommendation to certify his procedure and thus is in the position to offer services transparent to all and also comparable to similar methods available on the market. The DIN recommendation is also a legitimate and due to its transparence a much desired document.This is also important because the standardization of deacidification methods contributes to the clarification whether the products offered are in accordance with the requirements set for proper conservation. Therfore this is an appeal to all archives and libraries, who for conservation purposes want paper deacidification done, ensure that the DIN recommendation is used as the basis for their tender description, and also demand that the provider offers permanent fulfilment of the DIN recommendation requirements."
