ISO 13254 is a standard that specifies a test method for the water tightness of thermoplastic products for non-pressurised applications. The standard describes how a test sample, consisting of the product to be tested or a pipe and/or fitting connection, is subjected to a specific internal pressure in order to check the tightness of the connection or product.
ISO 13259 is a standard that specifies test methods for the tightness of elastomeric sealing ring joints in underground, unpressurised piping systems made of thermoplastics. It describes various test pressures and conditions for checking the tightness of such connections.

The test stand consists of a test chamber with sliding doors. The sliding doors serve to protect against water jets in the event of a leak in the specimen.
The supply unit is located outside the test chamber. A crossbeam is located at the top of the chamber for mounting and disassembling the specimen. This is used to attach lifting straps for mounting and disassembling the specimen. The specimen is clamped between two bearings.
In the area of the pipe connection, the specimen is supported on a longitudinally adjustable support and secured with a strap. The bearing on one side is mounted on a deflection carriage.
