Thermoplastics piping systems for underground non-pressure applications. Test method for leaktightness of elastomeric sealing ring type joints Ingestion-build-143074 BS EN 61883-4:2009 includes someWhat is ISO 13259 about? ISO 13259 specifies a test method for determining the leak tightness of elastomeric sealing ring type joints for buried thermoplastics non pressure piping systems. ISO 13259 also describes the following four test conditions under which the tests are performed: Condition A: without any additional diametric or angular deflection. Condition B: with diametric deflection Condition C: with angular deflection Condition D: with
