Conservation of cultural heritage - Extraction and determination of soluble salts in natural stone and related materials used in and from cultural heritage
保护文化遗产 - 在文化遗产中使用的天然石材和相关材料中的可溶性盐的提取和测定
This European Standard 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 restoration. 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+
