Conservation of cultural heritage - Desalination of porous inorganic materials by poultices

This document specifies one method for the desalination by poultices of porous inorganic materials constituting cultural heritage. The desalination methodology can be applied to salt-loaded porous inorganic materials either affected by salt weathering and/or to allow conservation treatments incompatible with soluble salt(s) contamination, or to prevent salt damage where contamination is known to be present. In all cases the desalination aims to decrease salt content.
Furthermore, this document gives the fundamental requirements for the desalination operation and guidelines for the choice of the most appropriate poultice components according to the characteristics of the substrate and types/quantities of salt(s) present in order to optimize the desalination process.

Erhaltung des kulturellen Erbes - Entsalzung poröser anorganischer Materialien durch den Einsatz von Kompressen

Dieses Dokument legt ein Verfahren für die Entsalzung poröser anorganischer Materialien, welche kulturelles Erbe darstellen, durch den Einsatz von Kompressen fest. Die Methodik der Entsalzung kann bei salzbelasteten porösen anorganischen Materialien angewendet werden, die entweder von Salzverwitterung betroffen sind, und/oder um Konservierungsbehandlungen zu ermöglichen, die mit einer Verunreinigung durch lösliches Salz/lösliche Salze unverträglich sind, oder um bei bekannter Verunreinigung Salzschäden zu verhindern. In allen Fällen ist das Ziel der Entsalzung die Verringerung des Salzgehalts.
Darüber hinaus enthält dieses Dokument die grundlegenden Anforderungen an den Entsalzungsvorgang sowie Leitlinien für die Wahl der am besten geeigneten Kompressenbestandteile entsprechend den Eigen-schaften des Untergrunds und den Arten/Mengen des/der vorhandenen Salze(s), um den Entsalzungsprozess zu optimieren.

Conservation du patrimoine culturel - Dessalement des matériaux inorganiques poreux par application de compresses

Le présent document spécifie une méthode de dessalement par compresses des matériaux inorganiques poreux constituant un patrimoine culturel. La méthodologie de dessalement peut être appliquée aux matériaux inorganiques poreux chargés en sel, soit affectés par l’altération par les sels et/ou pour permettre des traitements de conservation incompatibles avec la contamination par le(s) sel(s) soluble(s), soit pour éviter les dommages causés par les sels lorsque la contamination est connue. Dans tous les cas, le dessalement a pour objectif de diminuer la teneur en sel.
De plus, le présent document fournit les exigences fondamentales pour l’opération de dessalement et les lignes directrices pour le choix des composants de compresse les plus appropriés selon les caractéristiques du substrat et les types/quantités de sel(s) présent(s) afin d’optimiser le processus de dessalement.

Ohranjanje kulturne dediščine - Razsoljevanje poroznih anorganskih materialov z oblogami

Ta dokument določa metodo za razsoljevanje poroznih anorganskih materialov z oblogami, ki predstavljajo kulturno dediščino. Metodologijo razsoljevanja je mogoče uporabiti za porozne anorganske materiale z visoko vsebnostjo soli, ki zaradi tega preperevajo, in/ali da se omogoči konzervativno obdelovanje, ki je nezdružljivo s kontaminacijo s topno soljo, ali za preprečevanje poškodb zaradi soli, kjer je kontaminacija ugotovljena. V vseh primerih je cilj razsoljevanja zmanjšati vsebnost soli.
Dokument prav tako podaja temeljne zahteve za postopek razsoljevanja in smernice za izbiro najprimernejših sestavnih delov oblog v skladu z značilnostmi podlage in vrstami/količinami prisotne soli za optimiziranje postopka razsoljevanja.
