Thermoplastics Piping Systems for Non-pressure
Applications - Test Method for Watertightness
1 Scope
This Standard specifies the test method for watertightness of thermoplastics piping
systems for non-pressure applications.
This Standard is applicable to products and plastic piping system joints made of two
ore more components through secondary processing.
2 Principle
Within the specified time, the secondary processed products or the assembly
composed of pipes and / or pipe fittings are subject to the specified internal hydrostatic
pressure. During the test, check the airtightness of the secondary processed products
or the assembly joints.
NOTE: the following test requirements may be provided by relevant standards:
a) Specimen preparation procedures in 4.1 and Chapter 5;
b) The number of specimens in 4.2.
3 Equipment
3.1 End Sealing Device
The joint assembly can be sealed and properly fixed; ensure that the sealing device or
specimen does not separate under the test pressure and no axial force shall be applied
to the specimen. The weight of the device shall not affect the deflection angle of the
specimen (see 5.2).
3.2 Hydrostatic Pressure Source
It is connected to at least one end of the sealing device. In accordance with the
requirements of 5.4, gradually and smoothly apply a pressure to the specimen. During
the test, the specified test pressure can be maintained, and the fluctuation range is
within 2െ1 % (see Chapter 5).
