2021 Amsterdam : A METHODOLOGY TO DETERMINE CHARPY IMPACT STRENGTH OF NOTHCED SPECIMEN CUT FROM PLASTICS PIPES
Author(s) : Li, Yanjun, Xiang, Aimin, Xu, HaiyunBeijing, Xie, Jianling, Ho, Kinman, Xu, HaiyunBeijing
It is necessary to evaluate the impact resistance of plastics pipes as they have the potential to be
damaged by hitting or colliding during storage, transportation and installation. As a well-established
test method, the Charpy impact strength of unnotched test pieces cut from thermoplastics pipes is

2012 Barcelona : What Is The Risk Of Plastic Pipe Long-Term Degradation On Water Quality?
Author(s) : B. Rabaud, J. Baron, A. Ragot, A. Bruchet, and K. Glucina
Plastic piping products present the advantage of not being affected by electrochemical
corrosion. However, they can be severely degraded after long-term service by oxidation
process notably in presence of chlorinated disinfectant. This study was conducted in
order to investigate the impact of plastic pipe degradation...
