ASTM F2164 – 13
Under test pressure, piping materials astm f2164 expand slightly in diameter and contract in length slightly according to the Poisson ratio of the material. Poisson-effect length reduction may affect or cause disjoining in other contiguous sections that astm f2164 partially restrained or non-restrained joints, such as bell-and-spigot joints, when such joints are in-line with the test section.
It is the responsibility of the astm f2164 of this standard to establish appropriate safety and health practices and determine the applicability of asstm limitations prior to use. It is the astm f2164 of the user astm f2164 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Contact the joint or connection manufacturer for information.
For safety reasons, some manufacturers prohibit or restrict pneumatic pressure testing of their products. For safety reasons, some manufacturers prohibit or restrict pneumatic pressure testing of their awtm. Contact sstm manufacturers for information about testing with gas astm f2164 pressure.

Contact component manufacturers for information about testing with gas under pressure. Active view current version of standard. In a compressed gas test, both the pressure stress on the astm f2164 and the energy used to compress the gas are released at a failure.
See also Test Method F Note 2 — When a tensile stress is applied to a material, it will elongate in the direction of the applied stress, and will decrease in dimension at astm f2164 angles to the direction of the applied stress.
In a compressed gas test, both the pressure stress on the system and the energy used to compress the gas are released astm f2164 a failure. Such systems may contain lower pressure rated or non-pressure rated components that cannot be astm f2164 from test pressure, or temporary caps or closures may not be practical.
The ratio of decrease to elongation is the Poisson ratio. It does not verify if a piping material or a piping system design is suitable for pressure service.
To prevent Poisson-effect disjoining, take measures such as the installation of external joint restraints diametrical clamps and tie-rods on in-line non-restrained joints, installing in-line thrust anchors at the ends of the fully restrained section, or isolating the fully restrained test section from piping with non-restrained or partially restrained joints. astm f2164
For field-testing of plastic gravity flow sewer lines, see Test Method F In the test phase, expansion is suspended by slightly reducing test pressure. In these systems, leak inspections astm f2164 be conducted during and after installation.
To compensate for expansion, make-up astm f2164 is added during the initial expansion phase. The amount of make-up water expansion allowance will vary because expansion is not linear.
This procedure compensates for expansion with an astm f2164 expansion phase, followed by a test phase. For field-testing of plastic gravity flow sewer lines, see Test Method F Leakage or faults usually occur at connections, joints, and mechanical seals astm f2164 sealing under pressure is required.
Failure during a pressure leak test can be explosive, violent, and dangerous, especially if a astm f2164 gas is used. Failure during a pressure leak test can be explosive, violent, and dangerous, especially if a compressed gas is used.
