Outdoor Performance of Plastics. VIII. First Update of Weathering Data

摘要

This report updates previous reports of the Manufacturing Chemists' Association's (MCA) project that was initiated in 1966. Since that time, 20 plastic samples have been exposed outdoors at three different exposure sites which represent varying climatic weather conditions encountered in the United States. The MCA project and its preliminary results have been described in a series of National Bureau of Standards Reports. These reports (1-7), are all entitled Outdoor Performance of Plastics.
