TNO (TNO Building and Construction Research, Delft) , IRPA-KIK (Royal Institute for the Cultural Ileritage, Brussels), and PDM (Politecnico Department of Structural Engineering, Milan) are involved in an EC research project 'Evaluation of the Performance of Surface Treatments for the Conservation of llistoric Brick Masonry'. Among the tasks in this project are: (a) to carry out 60 case studies of treated brick masonry monuments, in order to evaluate the performance, to collect knowledge on types of damage, darnaging processes and causes of damage and to fInd out about the relation between treatment and damage, and (b) to evaluate and improve test methods and eventually develop new methods or procedures. For two of the test methods, meant to assess the performance and to diagnose the damage, a proposal is presented and discuseed
