Contact the joint or connection manufacturer for information. 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.
In a compressed gas test, both the pressure stress on the system and the energy used to compress the gas are released at a failure. Active view current version of standard.

The ratio of decrease to elongation is the Poisson ratio. For field leak testing using pressurized gas, see Practice F It does not verify if a d2164 material or a piping system design is suitable for pressure service. For safety reasons, some manufacturers prohibit or restrict pneumatic pressure testing of their products. The amount of make-up water expansion allowance will vary because expansion is not linear.
Failure during a pressure leak test can be explosive, violent, and dangerous, especially if a compressed gas is used. Link to Active This link will always route to the current Active version of the standard.
See also Test Method F It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Contact component manufacturers for information about testing with gas under pressure.
The suitability of a piping system for pressure service and its pressure rating or operating pressure is determined solely by its design and its installed components. 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 right angles to the direction of the applied stress.

Leakage or faults usually occur at connections, joints, and mechanical seals where sealing under pressure is required. Warning —Safety is of paramount importance when conducting hydrostatic pressure leak tests because testing under pressure may cause sudden violent rupture 2f164 failure. Link to Active This link will always route to the current Active version of the standard.
For field-testing of plastic f1264 flow sewer lines, see Test Method F In these systems, leak inspections should be conducted during and after installation. For field-testing of plastic gravity flow sewer lines, see Test Method F To compensate for expansion, make-up water is added during the initial expansion phase.
Inspections typically include visual examination asgm joint appearance, mechanical checks of bolt or joint tightness, and other relevant examinations.
Under test pressure, piping materials will expand slightly in diameter and contract in length slightly according to the Poisson ratio of the material. In a compressed gas test, both the pressure stress on the system and the energy used to compress the gas are released ast a failure.
Historical Version s – view previous versions of standard. For safety reasons, some manufacturers prohibit or restrict pneumatic pressure testing of their products.
Such systems may contain lower pressure rated or non-pressure rated components that cannot be isolated from test pressure, or temporary caps or closures may not be practical. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Failure during a pressure leak test can be explosive, violent, and dangerous, especially if a compressed gas is used. Poisson-effect length reduction may affect or cause disjoining in other contiguous sections that have partially restrained or non-restrained joints, such as bell-and-spigot joints, when such joints are in-line with the test section. Additional safety information is presented in Section 7 and throughout this standard.
