Under test pressure, piping materials will expand slightly in diameter and contract in length slightly according to the Poisson ratio of the material. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Warning —Safety is of paramount importance when conducting hydrostatic pressure leak tests because testing under pressure may cause sudden violent rupture or failure. Contact component manufacturers for information about testing with gas under pressure.

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. 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.

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. Additional safety information is presented in Section 7 and throughout this standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Inspections typically include visual examination of joint appearance, mechanical checks of bolt or joint tightness, and other relevant examinations.

Contact the joint or connection manufacturer for information. Additional safety information is presented in Section 7 and throughout this standard. The ratio of decrease to elongation is the Poisson ratio. Historical Version s – view previous versions of standard. See also Test Method F Active view current version of standard. To compensate for expansion, make-up water is added during the initial expansion phase.

For safety reasons, some manufacturers prohibit or restrict pneumatic pressure testing of their products. Work Item s – proposed revisions of this standard.

For field leak testing using pressurized gas, see Practice 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 Aatm The suitability of awtm piping system for pressure service and its pressure rating or operating pressure is determined solely by its design and its installed components.

Link to Active This link will always route to the current Active version of the standard. It does not verify if a piping material or a piping system design is suitable for pressure service.

Leakage or faults usually occur at connections, joints, and mechanical seals where sealing under pressure is required.

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. In the test phase, expansion is suspended by slightly reducing test pressure. 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.

Work Item s – proposed revisions of this standard. For field-testing of plastic gravity flow sewer lines, see Test Method F The amount of make-up water expansion allowance will vary because expansion is not linear. 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.

This procedure compensates for expansion with an initial expansion phase, followed by a test phase. 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. Failure during a pressure leak test can f264 explosive, violent, and dangerous, especially if a compressed gas is used. For safety reasons, some manufacturers prohibit or restrict pneumatic pressure testing of their products.

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.
