Subject: ASTM paper aging research program
Since 1994, ASTM has been engaged in a major research program into the aging of printing and writing papers. Its goal was to develop scientifically sound methods by which to accelerate the aging of such papers. That goal has now been met. Three test methods have been developed. They use elevated temperature, elevated light flux and increased concentration of common atmospheric pollutant gas to accelerate the aging. To be considered scientifically sound, the research had to demonstrate that the chosen methods produced essentially the same chemical and physical changes in the paper as occur over long term natural aging. The research shows that the proposed methods are, indeed, scientifically sound. Five internationally distinguished laboratories participated in the research. Light aging studies were conducted at the USDA Forest Products Laboratory in Madison, WI and at KCL (the Finnish Pulp and Paper Research Institute) in Espoo, Finland. The pollutant studies were carried out at the Image Permanence Institute at Rochester Institute of Technology in Rochester, NY. The temperature studies were performed at the US Library of Congress in Washington, DC and at the Canadian Conservation Institute in Ottawa, ON. Thirty-three organizations sponsored this $4 million (USD) program. They ranged from pulp and paper companies and their suppliers to a number of distinguished organizations in the library, archive and museum communities.
