Conservation of cultural heritage - Determination of soluble salts in natural stone and related materials used in cultural heritage
EN 16455 provides a methodology for the qualitative and quantitative analysis of anions and cations obtained by dissolution of soluble salts present in either natural stone or other porous inorganic materials constituting cultural heritage and in materials and products used for their conservation. The methodology requires samples to have been taken from the cultural property. The main ions considered in this standard are: Cl-, NO2-, NO3-, SO42-, Na+, K+, NH4+, Ca2+, Mg2+.

Diese Norm legt ein Verfahren für die qualitative und quantitative Bestimmung von Anionen und Kationen fest, die durch die Auflösung von löslichen Salzen – aus Naturstein oder anderen porösen anorganischen Materialien wie Mörtel, Stuck, Ziegel, und keramischem Material stammend – erhalten wurden.
Bei den in dieser Norm betrachteten Ionen handelt es sich um:
Cl-, NO2-, NO3-, PO43-, SO42-, C2O42-, CO32-, Na+, K+, NH4+, Ca2+, Mg2+
Conservation du patrimoine culturel - Détermination de la teneur en sels solubles de la pierre naturelle et des matériaux associés utilisés dans le patrimoine culturel
La présente norme fournit une méthodologie pour l’analyse qualitative et quantitative des anions et des cations obtenus par dissolution des sels solubles présents dans la pierre naturelle ou dans d’autres matériaux poreux inorganiques tels que les mortiers, le stuc, la brique et la céramique.
Les ions considérés dans la présente norme sont les suivants :
Cl-, NO2-, NO3-, PO4 3 - , SO42 -, C2O42 -, CO32-, Na+, K+, NH4+, Ca2+, Mg2+
Ohranjanje kulturne dediščine - Ugotavljanje topljivih soli v naravnem kamnu in sorodnih materialih, uporabljenih v kulturni dediščini
Standard EN 16455 določa metodologijo za kvalitativno in kvantitativno analizo anionov in kationov, pridobljenih z raztapljanjem topljivih soli, prisotnih v naravnem kamnu ali drugih poroznih anorganskih materialih, ki predstavljajo kulturno dediščino, ter v materialih in izdelkih, ki se uporabljajo za njihovo ohranjanje. Metodologija zahteva odvzem vzorcev iz kulturne dediščine. Glavni ioni, obravnavani v tem standardu, so: Cl-, NO2-, NO3-, SO42-, Na+, K+, NH4+, Ca2+, Mg2+.

EN 16455:2014 (E) 4 Introduction Soluble salts are often present in stones and other porous inorganic building materials as alteration products of chemical or biological origin. They can originate from surface deposition of environmental pollutants or from water capillary transport from other external sources and also from materials themselves or from conservation interventions. Soluble salts present in porous inorganic materials can, (depending on material properties, environmental conditions or possible treatments the surrounding conditions), initiate physical-chemical degradation processes. This standard describes a procedure to extract soluble salts present in porous inorganic materials to determine the ions and to estimate the content of soluble salts. There are several test methods for the analysis of salts, for example: a) recognition of salt crystals by microscopy; b) qualitative chemical reactions. These make it possible to identify the type of anions and cations present in a solution, after dissolution of salts in water (i.e. sulphates, nitrates, ch
