Beurteilung des Langzeitverhaltens der Fuegenaehte von Kunststoff-Dichtungsbahnen zur Basis- und Oberflaechenabdichtung bei Deponien Schlussbericht

Abstract

Using PE (Vestolen A 3512 R) - sheetings of 2 mm and 3 mm thickness, the applicability of conventional short-time tests for evaluation of weld seam quality were evaluated. It is demonstrated that current short-line tests provide no reliable data. A long-time stress reference test at elevated temperatures is proposed as a practice-relevant accelerated life test. First relationships between welding parameters, geometrical parameters and reference test results are compiled. Criteria are given for the evaluation of seam quality.
