In the field of conservation, new consolidation products or intervention technologies are sometimes introduced before their impact on historical substances has been tested and verified. This happens because evaluating the impact of new agents on cultural heritage is not an easy task, which usually does not aspire to study all possible effects or to attain absolute standard values because relative data are mostly sufficient for decision-making. The effects on real materials and under real conditions of application and action should be examined, nonetheless, in practice investigations are usually carried out in laboratories. There are no comprehensive standard procedures for assessing consolidation effects on stones, especially when small-sized specimens are to be tested. Tabasso and Simon published a critical review of testing methods for the assessment of stone properties before and after conservation treatment, in it, the reader can find useful information on various standard as well as non-standard techniques. The testing of stones and evaluation of conservation interventions, including recommendations for compatibility criteria, have been studied further mainly in Germany, where many innovative ideas have originated. This chapter presents examples of test methodologies which have not been standardized but were specifically designed or are useful for dealing with practical tasks. The selected tests were intended to provide results which would best enable the characterization of the consolidation effects from the point of view of maximum efficiency, with no or negligible harmful consequences for the given rock.
