Tightness testing of individual pipe joints using water and air overpressure Examination of the test criteria

摘要

Tightness testing of waste-water ducts and lines can be performed either globally or section by section. In the case of section-by-section testing, the pipe joints in the ducts and lines are very frequently examined, since they constitute a weak point in the system under examination. Shortcomings in the test criteria specified in DIN EN 1610 for establishment of the Tightness of individual pipe joints became apparent during the research project per- Formed by the Institute for Construction Machinery and Procedure.
