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 conservation. The methodology requires samples to have been taken from the cultural property.

The main ions considered in this standard are:

Cl^-, NO₂ ^-, NO₃ ^-, SO₄ ^{2 -}, Na⁺, K⁺, NH₄ ⁺, Ca²⁺, Mg²⁺
