Several techniques of polymer characterization and different aging methods have been used with the aim of developing a simple, fast and reliable method to qualify com. pipe-grade polyethylene samples, and possibly to evidence the presence of recycled PE within PE pipes. The results of the different techniques used have been compared with respect to their capability to evidence differences in the degrdn. rate of different HDPE samples (including virgin HDPE, HDPE pipes obtained from virgin HDPE and HDPE pipes that probably contain recycled HDPE).

Abstract
Several techniques of polymer characterization and different aging methods have been used with the aim of developing a simple, fast and reliable method to qualify com. pipe-grade polyethylene samples, and possibly to evidence the presence of recycled PE within PE pipes. The results of the different techniques used have been compared with respect to their capability to evidence differences in the degrdn. rate of different HDPE samples (including virgin HDPE, HDPE pipes obtained from virgin HDPE and HDPE pipes that probably contain recycled HDPE).
