Building materials and furnishing used in contact with indoor air may have a positive effect to moderate the variations of indoor humidity seen in occupied buildings. Thus, very low humidity can be alleviated in winter, as well as can high indoor humidity in summer and during high occupancy loads. This way, materials can be used as a passive means of establishing indoor climatic conditions, which are comfortable for human occupancy, or for safe storing of artefacts which are sensible to humidity variation. But so far there has been a lack of a standardized quantity to characterize the moisture buffering capacity of materials. The objective of the NORDTEST project on Moisture Buffering of Building Materials has been to develop such a definition, and to present it in the form of a NORDTEST method. Apart from the definition of the Moisture Buffer Value, the project declares a test protocol which expresses how materials should be tested. The test protocol constitutes the project's proposal for a NORDTEST method, and can be seen as Appendix 1 of this report. Furthermore, as a part of the project some Round Robin Tests have been carried out on various typical building materials.
