Development of Performance Criteria for the Selection of Stone Preservatives
This paper describes how test methods and performance criteria for the selection of stone preservatives are being developed. Accelerated aging of stone and of preservative treated stone followed by tests of the aged specimens is used to evaluate both test methods and stone preservatives. The laboratory aging procedure incorporates important causes of stone decay--Chemical Attack, Salt Action, Water Action, Thermal Effects--in a special test chamber (CAD) and test cycle. The effects of the accelerated aging on the weight, appearance, absorption of liquid water, permeability to water vapor, abrasion resistance, and surface hardness of the treated test specimens are used as measures of preservative performance. It is explained how this test data and the test methods employed can be used to set performance criteria for the selection of stone preservatives.
