    Abstract

    Following up on ASTM MNL 18, Moisture Control in Buildings, ASTM Committees C16 and E06 now co-sponsor ASTM MNL 40, Moisture Analysis in Buildings. MNL 40 expands the chapters on Modeling and on Design Tools and adds to the chapters on Weather Data and Materials Data of MNL 18, published in 1994.

    The purpose of the new manual is to provide an overview of the current state of moisture analysis in buildings, to encourage the use of moisture analysis by building designers and practitioners, and to provide the necessary technical background for conducting moisture analysis as an integral part of building design. The manual consists of ten chapters written by individual experts. Included are an extensive Glossary of terms used in moisture analysis and a moisture primer addressing the reader with no or with only limited understanding of hygrothermal mechanisms. Other chapters discuss weather and material data and failure criteria. The manual continues with two overviews of analysis methods, a chapter on manual methods and chapters on the models MOIST and WUFI ORNL/IBP. The manual concludes with a Look to the Future. Enclosed with the manual are CD-ROM disks with the programs for MOIST and WUFI ORNL/IBP, including the necessary owners manuals, and with two conversion programs for properties of air.
